A First edition for PIB30.

1 SYSTEM DESCRIPTION

1.1 Overview

General

The Simrad PI30 is an integration of proven marine technologies into a comprehensive tool specifically deigned for purse seining. This robust and maintenance-free monitoring system allows unparalleled control over the fishing operation by providing continuous, centralised information concerning the vessels position, gear and the environment at and below the water's surface.

System components

The PI30 Purse seine system is made up of a control and display unit, hydrophone and one or more sensors attached to the bottom of the net.

Figure 1 - PI30 components

1 PI30 Display and control unit
2 PS30 Depth sensor
3 PS30 Depth sensor
4 Optional PS30 temperature sensor
5 Hydrophone

The system is designed to be used with up to three sensors, optimally two depth sensors and one temperature sensor. Variations in this configuration may be made to suite individual needs.

PI30 p#p#seiseine system primary functions

The PI30 is a multi-functional instrument that has been designed to aid in the following:

•Purse seine monitoring

- Net depth at three locations or

- Water temperature and net depth at two locations

- Echo sounding*

- Water temperature at surface

- Water depth

- High resolution fishfinder - Bottom discrimination

- Navigation**

- Numerical GPS repeater

- Graphical track information

- Speed / Heading / Distance to WP / Time to WP / Cross track error

*Requires interface with an optional echo sounder transducer or triducer.

**Requires interface with an optional GPS.

Derivable purse seine information

Using the known relative location of the sensors attached to the purse seine, combined with the information they transmit, the following may be derived:

- When to begin pursuing.

•Optimal speed to purse.

•Risk of of pursuing over a school of fish.

- Risk net damage due to contact with the bottom.

- Risk ecological damage to the bottom and its inhabitants due to net contact or loss.

- Net sink rate.

- When the net has stopped sinking.

- When the net has started rising.

•Water temperature at different depths.

- When the net passes the thermo cline.

1.2 PI30 Display and control unit

General

The Display and control unit is a water-proof, marine grade electronic instrument incorporating an impact resistant polycarbonate front panel, die-cast aluminium housing and watertight electrical connections.

Display and control unit components

The PI30's electronics are sealed in the display and control unit allowing the it to be flush or bracket mounted in the wheelhouse or at an exposed control station.

1.3 PS30 Depth sensor

The PS30 Depth sensor is protected by a shock-absorbing, abrasion-resistant polyurethane shell and is designed to survive the extreme forces encountered at depth and while shooting and hauling a purse seine.

Yellow plastic object with four black circular holes, resembling a stylized helmet or cushion (no text or symbols visible)

Figure 5 - PI30 Depth sensor

Housed safely inside the unit are the electronics and self-contained power supply used to send depth information to the hydrophone connected by shielded cable to the display and control unit.

To further enhance sensor strength and avoid corrosion high grade titanium is used for all metal parts. The HyperYellow exterior colour provides maximum visibility to aid in retrieval. The compact design, quick update rate, extensive battery life and long-range transmission capability allows the PS30 Depth sensor to be used with any size net.

PS30 Temperature sensor

The PS30 Temperature sensor is physically identical to the PS30 Depth sensor with the exception that its function is to read and transmit the ambient water temperature.

Sensor codes

Differently coded signals for individual sensors are available to avoid interference from other vessels operating in the vicinity. Sensor codes can be programmed in the field using a computer.

Sensor charger

Three different Simrad sensor chargers are available depending on the vessel's main power supply:

• 220 VAC - Simrad sensor charger (reg. nr. 107-073189).
• 110 VAC - Simrad sensor charger (reg. nr. 107-073190).
• 24 VDC - Simrad sensor charger (reg. nr. 107-204060).

Exterior view of a SIMRAD sensor charger connected to a white electrical plug and coiled cable (no text or symbols visible on main subject)

Figure 6 - Simrad Sensor charger

Hull mounted Hydrophone

The hull mounted hydrophone has a 90^ horizontal beam and a 30^ vertical beam to provide the PI30 with optimal reception from the sensors. Its beam diagram makes it especially effective for use in purse seining and the wide coverage area reduces the need for careful alignment.

→ See figure 7.

Figure 77 Hull mounted hydrophone and cable

Portable Hydrophone

The portable hydrophone is designed as a temporary measure until a fixed hydrophone can be installed at the vessel's next planned dry docking. It has an omni-directional beam and a 50m integrated cable which is sheathed in polyurethane providing robust external protection to compliment its 150 kg tensile strength. The cable is supplied on a reel for convenient retrieval/stowage and is equipped with a plug for easy attachment to the control cabinet.

Sensor calibration

Sensors are calibrated at Simrad before shipment, but may be calibrated at any time on board the vessel. The reference level (distance from the surface of the water to the sensor) used as the basis for depth calculations may be changed from the default setting of 1.0 m to + or - 9.9 m.

Sensors may be calibrated simultaneously (or individually) as follows:

1 Suspend the sensors one meter below the water's surface, the vessel's draft plus one meter or the depth to be used as the reference point which will be displayed as one meter on the LCD. Offset values can also be entered directly, but is not recommended.

2 Energise the PI30 Display and control unit and open the Sensor alarm/calibration window.

3 Note the displayed offset values for each of sensors before calibration on the Sensor calibration table (table 1).

4 Check that depth values from all of the sensors are being received, sensors that do not transmit will not be calibrated.

5 Select, Calibration: YES in the Sensor alarm/calibration window. This will open the Warning window.

6 Press MENU to cancel or ENT to calibrate the sensors.

7=Commencing the calibration sequence will reset all values and .= will be displayed. Proper calibration requires that ten consecutive pings (taking approximately one minute) be received. The sensors' respective depth values (e.g. 1.0 m) will be displayed once they are calibrated.

8=The sensors' internal data has now been updated and a depth of one meter should be displayed confirming that successful calibration has been accomplished. New offset values have also been updated and should be noted on the Sensor calibration table (table 1) for future reference.

4 REFERENCE

4.1 Purse seine display references

Overview

Purse seine functions provide continuous monitoring of the fishing operation with regard to the gear and environment. The three available displays from the purse seine drop-down menu are:

• Numeric display
• Graphic display
• Status display

Numeric display with three depth sensor windows

Information concerning up to three depth sensors is horizontally grouped using three different background colours. It is broken down both numerically and symbolically to provide a quick reference for the depth, rise/sink rate and alarm levels of each sensor. By combining this data with the known attachment locations of the sensors to the purse seine, the captain can determine the depth of the net under the surface and if it has, or is about to, stop sinking or begun to rise.

Figure 54 - Numeric display using three depth sensors

1 Senors - Depth sensors are designated by a D1, D2 or D3 and each corresponds to a respective data window. Individual attachment locations to the purse seine must be known so that the displayed numeric information may be properly evaluated.

2 Alarms - Alarm warnings are represented by triangle. Apex up indicates the value is below the alarm level, apex down indicates the value is above the alarm level. Alarm functions are accessed via the Sensor setup alarm/calibration window.
3 D e p t h - Numeric information is calculated and dis in accordance with the units selected. Sensor information is not being received if “*.*” is displayed in place of the depth value. Uncertain readings are indicated by the depth value changing from black to grey.
4 Sensor movement - The black triangular arrow pointing downward indicates the sensor is descending. A black triangular arrow pointing upward indicates the sensor is ascending.
5 Units - Are selected in the Setup for Speed alarm, units and language window.
6 Interference icon- Indicates signal interference due to an other vessel operating in the vicinity. Differently coded signals for individual sensors are available and can be programmed in the field using a PC.
7 Pulse lamp - Signal reception is indicated when the yellow pulse lamp is blinking.
8 Sink rate - Displays the respective sensor's vertical velocity in the selected units per minute.

Note!

Data windows may be displayed in the order which best represents their respective sensors' location on the purse seine. Data window background colours (which aid in the interpretation of displayed data) are selected in Pallet setup. An empty data window signifies that no sensor has been correlated with that particular window.

Numeric display with two depth and one temperature sensor windows

Information concerning up to two depth and one temperature sensors is horizontally grouped using three different data window background colours.

→ Refer to figure 55.

1 Sign - A plus (+) or minus (-) symbol before the value indicates if the ambient water temperature around the sensor is above or below the freezing point for fresh water.
2 Temperature - The ambient water temperature around the sensor.
3 Units - Temperature is displayed in either °C or °F as indicated following the displayed value.

Figure 555 Nu Numeric display using two depth and one temperature sensor
4 Temperature change - A black triangular arrow pointing downward indicates the water temperature in the vicinity of the sensor is decreasing. A black triangular arrow pointing upward indicates that it is increasing.

Numeric setup

Pressing ENT with the Numeric display open will activate the Numeric setup window.

Numeric setup:
Data window 1:	Depth 1 - sensor 1
Data window 2:	Depth 2 - sensor 2
Data window 3:	Depth 3 - sensor 3
Show graphic alarm:	ALWAYS

Figure 56 - Numeric setup window

Variable parameters in the Numeric setup are:

- Data window 1, 2 and 3: Is used to select which sensor is displayed in which data window. This is to help give an overview when several sensors are attached to the purse seine. It is not possible to “remove” sensors and only configurations that agree with regard to senor type are allowed (conflicting combinations will not be registered).

• Show graphic alarm: ON, OFF, ALWAYS

• ON - Displays a graphic alarm when the acoustic alarm is activated.
• OFF - No alarm is displayed.
• ALWAYS - Displays a graphic alarm for values within the selected alarm parameters even if the alarm function is set to OFF in the Sensor alarm/calibration window.

Graphic Display

To differentiate between sensors, information is grouped using the same background colours as the numeric display. The graphic display provides a historic plot of the sinkrate profile of the purse seine.

If an optional echo sounder transducer is installed, the echo sounder display may be superimposed over the graphic display so that data may be compared.

Note ! In this case it is recommended to operate the echo sounder on a frequency of 200kHz to avoid interference with the sensors.

Graphic display information may also be superimposed on an external echo sounder which is capable of reading data in NMEA format.

Depth sensors

Figure 57 - Graphic display using three depth sensors

Data windows - Display sensor depth, pulse lamp activity, and sensor identification, they correspond to the data windows used in the numeric display.

1 Main body - Illustrates the sinking profile of the net by means of a depth/time line graph. Individual curves correspond to their respective sensor data windows and are identified by like colours.
2 Time scale - Displayed in minutes on the bottom of the window and is dependent on scroll speed settings.
3 Bar graph - Illustrates the depth of the purse from a "side view" perspective. Individual bars correspond to respective sensor data windows and are identified by colour. The horizontal black hash marks designate the upper and lower selected alarm ranges for each sensor.
4 Depth scale - Display in the scale selected, common for main body and bar graph/alarm range information.

With temperature sensor

Status display

The status display provides an overview of PI30 data and insight into the system's performance. This is the first place to look if the system malfunctions.

Information regarding receiver monitoring, digital signal processor (DSP) efficiency and signal to noise ratio (S/N) are conveniently displayed in one main window. Access to such information is a valuable tool in helping to diagnose problems related to the system's hydro- acoustic communications link. The display is designed so that the user can easily interpret and forward critical system information to a shore based technician who can assist in troubleshooting any problems that may arise.

4.3 Echo sounder display references

Overview

Echo sounder functions provide primary information with regard to the depth, bottom and targets under the vessel when the PI30 is connected to an optional echo sounder transducer (refer to the Simrad EQ32 operator manual).

The PI30 has two different Echo sounder drop-down menus available. The complete drop-down menu is made up of six choices and the abbreviated version is made up of four. The Turn A-scope ON/OFF and Turn VRM ON/OFF drop down menus do not activate display windows.

The abbreviated Echo sounder drop-down menu is displayed when the unit is turned on for the first time or after being reset using the Master reset function. To replace the abbreviated drop-down menu with the complete version:

The four available displays from the abbreviated Echo sounder drop-down menu are:

• Echo display
• Bottom expansion
  •VRN expansion
• Echo sounder setup

General

The PI30 must have an optional echo sounder transducer installed to enable the corresponding functions. Specific echo sounder parameters are accessed through the Presentation setup window activated by pressing ENT while the corresponding main function window is displayed. General echo sounder parameters are selected in the ECHO (main menu) and Echo sounder setup (drop-down menu).

Echo display

The basic presentation mode (Echo display window) is primarily used for observing schools of fish and the seabed.

Sensor configuration & receiver setup information:

- Sensor 1: Set to either DEPTH, TEMPERATURE or NONE and Channels 1 to 30 or NO.

- Sensor 2: Same as above.

- Sensor 3: Same as above.

• Hydr. audio: Not implemented.

• Volume: Not implemented.

- AGC: Automatic Gain Control, the default setting is ON and is controlled manually in steps of 0, 20 and 40 decibels when set to OFF.

- Manual gain - When AGC is set to ON this setting has no effect. Manual gain is useful when working at maximum detection ranges with favourable noise levels. The default setting is 0 decibels. Refer to the section discussing the status display for more information.

- MP filter / MPF level: The Multi Path filter default setting is OFF and the Multi Path level default setting is 42dB. When the Multi Path filter is set to OFF, the Multi Path level is not of consequence.

Operating in an areas with substantial reverberation due to bottom topography or in shallow waters can cause problems when consecutive operating channels have been configured, but the corresponding sensors are not in use. False signals and sporadic error values can also be caused by other types of hydro acoustical equipment operating on PI30 frequency range.

The MP filter should be set to ON when interference is experienced. If this does not help, adjust the MPF level in small steps to correct the situation (lower values represent stronger filtering). It is best to experiment with this parameter by reducing the value in steps of 3dB until the detection error disappears. Check that the signals from the sensor in use are still being received, if they are not, the MP filter will not be of help in this particular situation. The MP filter's effectiveness is both location and net specific. Therefore, the same parameters will not necessary work in different areas or using various types of nets.

• Max shooting speed: From 0 to 20 knots.

The PI30 has a built in Doppler compensation function which is configured using the Max shooting speed (the default value is five knots). This parameter and related function is only relevant if sensor data is desired while the purse seine is being deployed and has no effect once the vessel is stopped, waiting for the net to sink. Be aware that setting the Max shooting speed parameter too high can create a conflict with the channel selection (Refer to the section on Setup for sensor alarm/calibration on page 33). Should this situation arise, the message "Max shooting speed differs from wanted, channels are set too close to each other" will be displayed.

- Detection Threshold (DT): Has a default value of 8dB. If there is a problem with interference signals generating false data and all of the configured sensors are operative (analogous with the Multi Path problem); increase the value carefully in steps of 1dB.

High DT values allow only strong sensor signals to be detected. A lower DT value will provide greater range if conditions are optimal, but if too low, interference will be detected. It is best to experiment with different values to determine which to employ.

Note!

If the Detection Threshold (DT) value is set higher than 28dB, all signals will be prevented from being detected.

- Sensor filter: OFF (default), LIGHT or HEAVY. When the Sensor filter is set to OFF, no filtering takes place. Light filtering averages the data received by the last four pings. Heavy filtering averages the data received by the last eight pings and is only recommended if there are large fluctuations in the displayed data, or the rate of change is small. Reduced filtering shortens the delay between updating the changes in sensor location and the corresponding displayed information.

The HP30 is designed to quickly update data. After the sensors have been submerged, the receiver requires only three consecutive pings from individual sensors to calculate and display their respective information. Should one or two pings be lost, the predicted value is displayed in grey text (uncertain reading). If all three pings where not received, the value is displayed as *.*

•Time: Present time
•Date: Present date

Sensor configuration & receiver parameters

Sensor configuration

Sensors can be configured in any combination. For example, sensor 1, 2 or 3 can be configured as depths 1, 2 or 3 representing the 1/4, 2/4 (1/2) and 3/4 sections of the purse seine, or as two depth sensors and one temperature sensor. What ever configuration is selected, the attachment locations of the sensors must be noted so that the received data may be properly interpreted.

Channel selection

Each sensor must be clearly marked before hand with its configured channel number (from 1 to 30).

→ Refer to figure 90 on page 83

These individual coded signals should be carefully chosen to avoid interference from other vessels operating in the vicinity. The selected operating channels for the individual sensors should be noted in the Sensor calibration table (table 1 on page 34).

Optimally, selected channels should be separated as much as possible to increase Doppler tolerance. The PI30's internal computer protects against incompatible channel selection due to Doppler tolerance conflicts and is controlled by the parameter Max shooting speed. Should two consecutive channels be chosen, Max shooting speed may be set to no more than six knots.

Display colour

The LCD colours may be customized as desired. There are nine different display settings for all objects and text shown on the screen.

6 MAINTENANCE AND REPAIR

6.1 General

Service

The PI30 Purse seine system does not contain any operator serviceable parts. Opening individual components will void their respective warranties and touching internal electrical parts may cause bodily harm. Consult the section on troubleshooting if the system is not working properly or contact your authorized Simrad dealer for service and repair.

Spare parts

Fuses (2AF) may be purchased from a chandlery or a marine supply store. If you require a Simrad part, please contact your authorized dealer.

6.2 PI30 Display and control cabinet

Surface cleaning

Wipe the cabinet and LCD with a clean cloth moistened with fresh water. For heavier cleaning, dip the cloth in a solution of mild dish soap and water. Be sure to avoid excessive moister or cleaning solutions that contain alcohol or petroleum products.

Electrical connections

Periodically check the electrical connections for corrosion. Make sure that all connections are tight and that cables are not frayed or worn.

6.3 PS30 Hydrophone

Cleaning

Periodically clean the face of the hydrophone with a plastic utensil using a scrubbing action. Do not use harsh abrasive or solvents.

Dry dock

Protect the hydrophone face from sand/water-blasting and painting.

6.4 PSS00 portable hydrophone

Cleaning

The portable hydrophone and cable should be cleaned with fresh water after use. Keep the plug at the end of the cable as dry as possible and avoid it from being immersed in water.

Storage

The hydrophone and cable should not be left on deck when not in use and stored on the supplied reel with the following general precautions:

•The cable does not chafe due to motion of the vessel.
- Avoid sharp edges that could damage the hydrophone cable insulation.
- Do not knot or kinked the cable.

6.5 PS30 Depth and temperature sensors

Cleaning

Sensors and related mounting hardware should be cleaned with fresh water after use and before storage.

Note ! The sensors are designed to turn themselves on automatically when week current passes from the cover to the fastening lugs. A film of residual sa on the surface of a sensor can conduct enough electricity to automatically energise the the unit and inadvertently drain the battery.

Extra protection

To protect against the build-up of salt, cover the surface of the unit and its cover with a thin layer of silicon grease.

7 BATTERY CHARGING AND TESTING

7.1 Charging PS30 sensors

General

PS30 depth and temperature sensors are charged in the same manner, each with its respective charger. Three different Simrad sensor chargers are available depending on the vessel's main power supply:

• 220 VAC - Simrad sensor charger (reg. nr. 107-073189).
• 110 VAC - Simrad sensor charger (reg. nr. 107-073190).
• 24 VDC - Simrad sensor charger (reg. nr. 107-204060).

Sensor charger with coiled cable and two clampers on a wooden surface (no text or symbols visible on main subject)

Figure 80 - Sensor charger

WARNING!

The use of chargers or procedures not specified in these instructions is forbidden. Incorrect charging of PS30 depth/temperature sensors can result in material damage or personal injury due to fire or explosion.

When to charge the sensors

The PS30 depth/temperature sensors' internal batteries are charged (normal charge) with a constant current of 50 mA. This allows the chargers to remain connected to the sensors for extended periods of time with no danger of overcharging.

PS30 sensors should be charged:

• After 30 hours of consecutive use.
- Not in use / storage.

7.2 Charging procedure

The following procedure will insure maximum battery life and optimal system performance:

1 Clean the tRS30S sensor in fresh water to remove salt.
2 Secure the PS30 sensor against the motion of the vessel. Ensure that the fastening lugs do not come in contact with conductive material. Completing the circuit between a negative and positive fastening lug will prevent charging.

Figure 81 - PS30 depth/temperature sensor

3 Attach the Sensor charger's red alligator clamp to one of the PS30 sensor's fastening lugs designated with a plus (+) symbol.
4 Attach the Sensor charger's black alligator clamp to one of the PS30 sensor's fastening lugs designated with a minus (-) symbol.

Note!

Check that there is direct metal-to-metal contact between the alligator clamps and fastening lugs. Objects such as wet rope separating the two metal surfaces or shorting of the positive and negative terminals may cause electrolysis with the possibility of severely damaging or creating a short between the fastening lugs.

5 Check that the red light on the Sensor charger is illuminated confirming that the alligator clamps are connected correctly.

If the battery is completely dead, the red light on the Sensor charger many not illuminate. Should this be the case, clean the sensor in fresh water and resume charging. Once the battery voltage begins to increase, the red light on the Sensor charger will illuminate and the sensor should then be charged for a minimum of 14 to 16 hours.

Note!

The red light will illuminate even if an object capable of conducting electricity, such as wet rope, is trapped between an alligator clamp and fastening lug.

6 Check that the PS30 sensor's internal light blinks every four seconds confirming that it is charging.
7 Charge sensors with flat batteries a minimum of 14 to 16 hours.

Note!

Never charge PS30 depth/temperature sensors at a temperature of lower than 0 ^ ( 32 ^ ).

7.3 Testing

Normal condition

Touch the test point (bare metal tab) on the depth cover and a fastening lug at the same time. This will cause the sensor to identify the channel it transmits on with a series of blinks and begin sending data if it is not programmed differently.

→See figure 90 on page 83.

Depleted battery

If the sensor does not blink, it should be charge for a few minutes and tested again. If it then blinks and begins to send data, it should be charged for at least 16 hours. If the sensor continues to just blink, charge it a little longer and then test it again.

Possible fault

If a charged sensor blinks its identification code every four seconds, there is a fault with the depth cover. Contact your nearest Simrad dealer.

8 SYSTEM INSTALLATION

8.1 General

Planning

Installation of the PI30 should be carefully planned keeping in mind that the supplied cable for connecting the display and control unit to the hydrophone is ten meters long.

Cable

Running the hydrophone cable through a grounded conduit greatly decreases the likelihood of interference. To further reduce the chance of poor system performance, the hydrophone cable should be installed away from other electrical cables or sources. If it is necessary to pass close to other cables, it is best to keep as much distance from them as possible and make all crossings at right angles.

Sealed system

The PI30 display and control unit, depth / temperature sensors and hydrophone are all factory sealed and do not contain any user serviceable parts. Opening the the system's components is unnecessary for installation and doing so will void their respective warranties.

Grounding

The PI30 is a sophisticated piece of electronic equipment. To reduce electrical interference and risk of electrical shock, properly ground the system using the designated terminal on the back of the display and control unit.

→ Note the location of the ground screw in figure 82.

Power source, fuse and power cable

Ensure that the DC power supplied to the PI30 is within the range of 10 to 32V. Note that only a 2 A fuse may be employed and that the power cable is firmly attached.

8.2 PI30 display and control unit

Mounting

The PI30 display and control unit's compact design and installation flexibility allow it to be flat, bracket, overhead, bulkhead or console mounted.

Figure 882- BacBack of PI30 cabinet

Bracket mounting

The display and control unit may be securely mounted on any flat surface using the supplied bracket. The unit is tilted as required by loosening and tightening the integrated pivot wheels on each side of the cabinet.

→See figure 83.

Bracket mounted

Figure 83 - Bracket mounted PI30

Mounting options

Bracket mounting of the PI30 is less complicated than flush mounting and affords greater flexibility with regard to screen orientation. Problems involving glare, background lighting or obstructed viability of the LCD may not be realised until after installation. In such cases the unit may be both tilted in the horizontal plan using the pivot wheels or the bracket re-mounted to change the aspect in the horizontal plane.

Figure 884 MoMounting options for the PI30

Flush mounting

The PI30 may be counter-sunk into any flat surface using the four screw holes hidden under the removable corners. Refer to the cut-out template for specific instructions.

→See figure 85.

8.3 Electrical connections

General

All of the PI30 system's cable connections are located at the back of the display and control unit. The hydrophone wire must be spliced as necessary.

→ See figure 106 on page 104.

Power supply connections

Cable

The internal voltage regulator allows the PI30 to operate normally with power supply fluctuations ranging from 10 to 32Vdc. The display and control cabinet is connected to the external power supply by the supplied 1.5m power cable.

Once the supplied cable is connected to the power source, push the plug as far as it will go into the two pin receptacle labelled PWR on the back of the PI30 cabinet. Turn the plug's coupling ring clockwise until it "clicks" into the locked position.

Fuse

Use the supplied 2AF fuse or a specified replacement. Jumping the circuit or using a non-specified fuse, even for a short period of time, may result in irreparable damage to the equipment.

Figure 85 - Flush mounted PI30

Hydrophone connection

Cable

The PI30 is connected to the hydrophone by the supplied 22 meter cable. The cable's female plug is pushed as far as it will go into the receptacle labelled ANT on the back of the display and control cabinet. Turn the plug's coupling ring clockwise until it "clicks" into the locked position. The PI30 must be turned off when connecting or disconnecting the hydrophone cable.

Note!

Do not plug the hydrophone's female plug into the receptacle labelled ECHO on the back of the display and control cabinet. This could damage the hydrophone by subjecting it to voltage higher than it was designed for.

NMEA 0183 interface connections

Cable

NMEA 0183 interface connections are made using the receptacle labelled NMEA on the back of the display and control cabinet. Turn the plug's coupling ring clockwise until it "clicks" into the locked position. The PI30 must be turned off when connecting or disconnecting the NMEA 0183 interface connections.

Sensor configuration

See the section on PI30 Setup on page 58.

9 SENSOR CONFIGURATION

General

Sensors are delivered from the factory configured with common default settings. Individual sensors may be re-programmed with regard to:

•30 different transmission channels
- LED control
- Ping control
- LED flash at start up

Sensor configuration normally takes place on shore and is performed by an authorised Simrad dealer. It may also be at sea as only a PC and the correct software is required.

The wide range of available channels allows several vessels using PI30 systems simultaneously to operate in the same area without interference.

Necessary equipment

The following is required for PC/sensor interface:

• PS30 Sensor Configuration Software (Simrad reg. nr. 889-204037)
  • A PC capable of running the configuration software

9.2 Self-made programming cable

Required parts

Should a Simrad programming cable not be available, it is possible to make an adequate substitution using the following:

• A 9-pin, Sub-D female connector
• Approximately one to two meters of 2- wire cable
• A 3 kohm resistor
- Two alligator clamps

Assembly procedure

The cable assembly procedure is as follows:

1 Connect pin number two of the 9-pin, Sub-D female connector to one end of the (+) lead of the 2- wire cable. At the other end of the (+) lead, connect the positive (red) alligator clamp.
2 Connect pin number five of the 9-pin, Sub-D female connector to one end of the (-) lead of the 2- wire cable. At the other end of the (-), connect the negative (black) alligator clamp.

3 Conceir the the sistor between pins number two and three of the 9-pin, Sub-D female connector.

4 Check both alligator clamps and respective pins for continuity.

10 DEPTH SENSOR ATTACHMENT

General

The correct attachment of depth sensors to the purse seine is vital to system performance and safety of the units. It is therefore highly recommended that the supplied stainless steel karabiners (two per sensor, Simrad reg. nr 099-204046), or their equivalent, be used. Also available as optional equipment through your Simrad dealer are the various wire and rubber straps described in the following chapter.

Coverage

A PS30 sensor transmit information in the form of sound waves from within its hemispherical top. This conically shaped transmission beam covers a sector of approximately 70^ from the vertical axis of the unit providing communication with the hydrophone even when not optimally oriented.

Figure 91 - PS30 transmission beam

Attachment

It is very difficult to control the orientation of sensors attached to a purse seine. They should normally be allowed to hang as freely as possible so that the centre of their beams are directed vertically providing symmetrical coverage on the surface. Special arrangements, or sensors attached differently than described in these instructions, must ensure that their beams are directed toward the hydrophone when pursuing.

The type of fishing operation provides the basis for which mounting arrangement should be used. Due to the fact that vessels, procedures, nets and related gear vary widely, it is not feasible to consider all possible alternatives and provide a method for each that will work.

The following information describes various scenarios for several common fishing operations. These instructions are to be used as a guide and sensor mounting should be tailored to suit individual needs as performance and experience dictate.

Attaching depth sensors to the purse line

Sensors are attached to a purse line using a purse ring, through which is passed a wire strop with two karabiners at either end made fast to the unit's topmost fastening lugs. This attachment method is only recommended when the purse rings are hung and deployed outboard of the bulwarks.

Diagram of a rope harness with hanging weights and a hanging weight labeled (CD5493), no text or symbols present.

Figure 92 - Purse line attachment

The benefits of attaching sensors to the purse line are they:

• Are located outboard of the bulwarks when shooting and are deployed directly into the sea avoiding contact with the vessel.
• Hang vertical when deployed and their orientation is negligibly effected when pursuing.
• Are easily removed from the purse line.
• Do not need to pass through the power-block.

The disadvantages of attaching sensors to the purse line are they:

• May be subject to bottom contact in the event the net sinks too deep.
  • May be lost if the purse line parts.

Attaching depth sensors to the bridle

Sensors are attached utilizing two bights of rope, spliced directly to the bridle with karabiners at each end which are secured to the unit's topmost fastening lugs. Alternatively, the bights of rope may spliced directly to the bridle and the sensor's topmost fastening lugs. Permanently securing the sensors removes any possibility for quick disconnection and care must be exercised when charging to avoid personal injury due to electrical shock and possible electrolysis damage to the sensors' fastening lugs (refer to the following cautionary note).

Caution!

Check that there is direct metal-to-metal contact between the alligator clamps and fastening lugs when charging the sensors. Objects such as wet rope separating the two metal surfaces may cause electrolysis with the possibility of severely damaging or creating a short between the fastening lugs.

Sensors may be removed from the bridle to avoid them from passing thought the power-block by attaching a relatively long rope strop to the sensor's bottommost fastening lugs and a seine ring. This attachment method is only recommended when the purse rings are hung and deployed outboard of the bulwarks.

Figure 93 - Bridle attachment

The benefits of attaching sensors to the bridle are they:

• Are located outboard of the bulwarks when shooting and are deployed directly into the sea avoiding contact with the vessel.
  • Hang relatively vertically when pursuing.
• May be easily removed from the bridle and do not need to pass through the power-block.

The disadvantage of attaching sensors to the bridle are they:

- May be subject to bottom contact in the event the net sinks too deep.

Attaching depth sensors to the footrope

Sensors are attached utilizing bights of rope that are spliced directly to the footrope and have karabiners at each end which are secured to the unit's topmost fastening lugs. The bights of rope must be long enough to allow the sensors to hang outboard and clear of the bulwarks when shooting. Alternatively, the bights of rope may spliced directly to the footrope and the sensor's topmost fastening lugs. Permanently securing the sensors removes any possibility for quick disconnection and care must be exercised when charging to avoid personal injury due to electrical shock and possible electrolysis damage to the sensors' fastening lugs (refer to the previous cautionary note). This method of attachment makes it difficult to remove the sensors before they pass through the power-block.

Figure 94 - Footrope attachment

The benefits of attaching sensors to the footrope are they:

- Are located outboard of the bulwarks when shooting and are deployed directly into the sea avoiding contact with the vessel.

• Hang relatively vertically when pursuing.

The disadvantage of attaching sensors to the footrope are they:

- Are difficult to remove before they pass through the power-block.

Attaching depth sensors to the footrope (tuna)

Sensors are attached utilizing strops that are spliced directly to the footrope and have karabiners at each end which are secured to the unit's topmost fastening lugs. The karabiners may also be bent directly to the chain which is secured to the footrope at a distance of 10 to 15cm. The separation should be such that a bridle is created suspending the sensor so that it is correctly orientated. Alternatively, the bights of rope may spliced directly to the footrope and the sensor's topmost fastening lugs. Permanently securing the sensors removes any possibility for quick disconnection and care must be exercised when charging to avoid personal injury due to electrical shock and possible electrolysis damage to the sensors' fastening lugs (refer to the previous cautionary note). This method of attachment requires that the sensor pass over the bulwarks or transom when the net is shot and therefore it must be properly secured to withstand the extreme forces involved.

Unstable communication between the hydrophone and sensors while the net is sinking, later stabilizing as the sinkrate decreases, is a sign that the sensors are not maintaining their vertical orientation. A solution to this problem is the attachment of approximately two to three kilos of ballast to the bottom of the sensors. Added weight will improve the vertical stability of the sensors as they sink.

→ Refer to figure 95.

The benefit of attaching sensors to the footrope (tuna) are they:

- Hang vertical when deployed and their orientation is negligibly effected when pursuing.

The disadvantage of attaching sensors to the footrope (tuna) are they:

- Follow the same path as the purse seine when hauling and shooting and may be subject to abuse.

Figure 995 FooFootrope attachment (tuna)

Attaching depth sensors to the net wall (tuna)

Sensors are attached utilizing strops that are spliced directly to the footrope and have karabiners at each end which are secured to the unit's bottommost fastening lugs. The karabiners may also be bent directly to the footrope at a distance of 10 to 15cm. The separation of the strops should be such that a bridle is created suspending the sensor so that it is correctly orientated. The sensor's topmost fastening lugs are secured to the net wall using elastic strops tensioned so that the units are held in a stable position.

Alternatively, the bights of rope may spliced directly to the footrope and sensor's bottommost fastening lugs. Permanently securing the sensors removes any possibility for quick disconnection and care must be exercised when charging to avoid personal injury due to electrical shock and possible electrolysis damage to the sensors' fastening lugs (refer to the previous cautionary note). Attachment of the sensors to the net wall may help to reduce the amount of abuse the units are subject to when the purse seine passes over the bulwarks or transom.

→ Refer to figure 96.

The benefits of attaching sensors to the net wall (tuna) are they:

- Are slightly better protected when shooting.

Figure 906 NetNet wall attachment (tuna)

- Maintain their vertical orientation as the net sinks.

The disadvantage of attaching sensors to the net wall (tuna) are they:

- Oriented in the same direction as the net wall when pursuing which may provide poor communication with the hydrophone.

Conclusion

This information is a basic guide to attaching sensors to a purse seine and not a substitute for common sense, good seamanlike practices or experience. Each installation must be considered individually and the best solution determined with regard its particular characteristics.

11 HYDROPHONE INSTALLATION

11.1 Overview

Hydrophone location

Correct installation of the PI30 Hydrophone is vital to the system's performance. Several variables must be taken into consideration, the most important of which is the vessel's construction. This guide is for use in selecting the best location for the hydrophone and includes a brief description of areas to be avoided.

Depth

Water just below the sea surface contains a myriad of small air bubbles created by the turbulence of breaking waves. The first five to ten metres may be heavily saturated in moderate seas with the greatest concentration and largest bubbles closest the surface.

Air bubbles disrupt sound waves in water. The degree to which they absorb and reflect such energy vary, but in some cases they can block hydrophone reception. It is therefore recommended to mount the unit as deep as possible.

Pounding danger

When a vessel is in ballast and pitching in heavy seas, it is important that the hydrophone not be lifted out of the water. Should a vessel pound so heavily that the hydrophone be exposed, sound reception will be interrupted and the unit may be damaged on impact.

The boundary layer

The flow of water in the immediate vicinity of the hull of a moving vessel is known as a boundary layer. This flow is responsible for underwater noise that can disturb hydrophone reception and its thickness is contingent on a vessel's:

•Hull form
- Size and number of underwater protrusions
• Velocity
•Hull roughness

The boundary layer is thin (laminar flow) near the vessel's bow and becomes thicker (turbulent flow) as it moves aft. Laminar flow is smooth with streamlines approximately parallel to the hull and contributes relatively little to noise created by flow. Conversely, turbulent flow is more disorderly and in turn contributes to a greater extent.

Air bubbles may also be introduced into the boundary layer. If the vessel's hull has little flare and is relatively narrow, bubbles may escape to the sea surface without incident. On the other hand a wide, flat hull with minimal deadrise is prone to trapping air bubbles no matter how little flare it has. Regardless of a vessel's hull form, hydrophones are generally recommended to be installed on the forward part of the hull to minimising the influence of both turbulence and air bubbles.

Figure 97 - An exaggerated view of the boundary layer.

Bulbous bow

The bulbous bow may be an acceptable hydrophone location. Should this position be chosen, the foremost part of the bulb is often best, but also the most susceptible to pounding.

Figure 98 - Hydrophone location on a bulbous bow

Propeller noise

When shooting the purse seine the main propeller is the dominant source of under water noise. The hydrophone should be placed as far away as practical and outside its line-of-sight.

Bow/sternthruster noise

Bow and sternthruster operation may severely effect hydrophone reception. Hydrophone installation closer than four meters to either is strongly discouraged.

When not in operation, bow/sternthruster tunnels create turbulence and hence underwater noise when a vessel is under way. Also, as a vessel pitches in heavy weather, thruster tunnels may fill with air or aerated water which can disturb hydrophone reception when released. Hydrophone installation should take into regard the noise and down stream disturbances found around and aft of thrusters.

Noise from protruding objects and other sources

The primary sources of underwater disturbance (other than a vessel's main propeller and bow/sternthruster) that affect hydrophone reception are:

• Main or bilge keels
• Zinc anodes
  • Cooling elements protruding from the hull
  • Equipment such as sonar hydrophones and pitot tubes
• Sea chests
  • Overboard discharges
• Dents in the hull

All appendages to the hull, indentations and pipe outlets are potential sources of underwater noise. They may act as resonant cavities amplifying noise at certain frequencies, create cavitation or turbulence. Hydrophones should not be located in the vicinity of such objects and especially not immediately aft of them.

Optimal location

The most influential factors effecting hydrophone reception common to most vessels are: noise from the main propeller, bow/sternthrusters and air bubbles. Taking these main sources of disturbance into consideration, the generally recommended location for mounting a single hydrophone is approximately one third the vessel's water-line length from the bow.

Installations requiring the use of two hydrophones may position the first as described above and the second forward of the bowthruster in conjunction with the transducer shoe for the echo sounder. Both hydrophones must be located at least four meters from the bowthruster.

Optimal hydrophone placement differs from vessel to vessel. Variables effecting hydrophone performance must be understood so that the best location may be chosen given a vessel's design and particular operation.

Figure 99 - Recommended fore and aft locations for single hydrophone installations (both locations are used with dual installations).

11.2 Hydrophone coverage area, horizontal orientation and tilt

General

Once the fore and aft placement of the hydrophone is decided, it is equally important to carefully consider its horizontal and vertical orientation. Hydrophone orientation can have a large influence on system performance.

The hydrophone's beam sensitivity is concentrated within a 90^ horizontal and -30^ vertical sector. Both keel and hull installations are to be located on the side of the vessel that the seine is shot.

Note!

These installation instructions and related drawings are for vessels shooting and pursuing to STARBOARD.

Horizontal coverage area

When the seine is normally located forward of the starboard beam when pursuing the following information should be taken into consideration:

- When the seine is pursed in the sector from approximately 000^ to 120^ relative to the bow, the hydrophone should be installed at an angle of 70^ to the vessels centre line.

→ See figure 100.

Figure 1000 To Top view of the PI30's horizontal coverage area. The hydrophone is installed at an angle of 70^ to the vessel's centre line.

- When the seine is pursed in the sector from approximately 030^ to 150^ relative to the bow, the hydrophone should be installed at an angle of 90^ to the vessel's centre line.

The most important elements with regard to the horizontal coverage area of the hydrophone are:

- An unobstructed line-of-sight to the PS30 sensor(s) attached to the purse seine.

•The hydrophone is directed at the middle of the net when pursuing.

- Two hydrophones may be used for applications requiring a large coverage area, see the section on Dual hydrophone installation for more information.

Vertical coverage area

The hydrophone has a vertical beam width of -30^ and should be tilted so that the most important part of the seine is adequately covered. Tilt should be no less than -15^ in most instances with the optimal tilt angle depending on the size (length/depth) of the seine in use. Heeling of the vessel after the seine is set must also be taken into consideration. For a large purse seine (about 1000m or longer) the recommend a tilt angle is -15^ plus the estimated angle of heel when the net is set. For smaller and deeper seines it may be necessary to increase the tilt angle.

Tilt angle

The tilt angle is a function of net length and depth and may be estimated as follows:

$$ \alpha = - [ \text { and } \text { tan } = (\text { depth / length } * \pi) - 1 5 ^ {\circ} + \beta ] $$

$$ \alpha = = \text { tilt } = \text { angle } $$

= angle = of = heel = (to = port) = after = deploying = the = purse = seine = to starboard

→ Hydrophone in blister (821-203072), page 120 to 122.

Keel mounted shoes

The hydrophone shoe may be keel mounted to avoid creating an appendage to the hull which may foul the purse wire.

- The=hydrophone=must=have=an=unobstructed=line-of-sight=to the=PS30=sensor(s)=attached=to=the=seine.

Figure 1001- Ke Keel mounted hydrophone shoe

• The centre of the hydrophone's beam should be directed as much as possible toward the bottom of the net where the PS30 sensors are located. The tilt angle should be increased with regard to the expected heel of the vessel.
• For a short and deep seine a tilt angle of 20^ to 25^ is recommended. For a short and shallow or large seine a 15^ tilt angle may be best.
• If monitoring of the headline under pursing is desired the hydrophone should not be tilted more than 15^ .
  •The hydrophone shoe should be mounted as deep as possible on the keel, but not so deep that it may be damaged while docking.
  •The hydrophone shoe should be streamlined to avoid creating turbulence and underwater noise. See the enclosed drawings for more information.
• For applications that require extensive coverage, regardless of net size, several hydrophones may be installed with different tilt angles. See the section on Dual hydrophone installation for more information.

Freestanding hydrophone in blister

If there is no risk that hull protrusions will be fouled by the purse wire, mounting the hydrophone in a freestanding blister is a viable option.

→ See figure 102.

Should this solution be chosen, the following must be taken into consideration:

Figure 1002-Fr Freestanding hydrophone in blister

• The centre of the hydrophone's beam should be directed as much as possible toward the bottom of the net where the PS30 sensor(s) arelocated. The tiltangles should be increased regard to the expected heel of the vessel.
• For a short and deep seine a tilt angle of 20^ to 25^ is recommended. For a short and shallow or large seine a 15^ tilt angle may be best.
• If monitoring of the headline under pursing is desired the hydrophone should not be tilted more than 15^ .
• For applications that require extensive coverage, regardless of net size, several hydrophones may be installed with different tilt angles.
  • See the enclosed drawings for more information on freestanding hydrophones.

Dual hydrophone installation

Large vessels and operations requiring a greater than normal coverage area can install two hydrophones with a vertical and horizontal overlap. Hydrophone selection is made with the help of a switch located in the wheelhouse.

To reduce the possibility of interference from air bubbles and underwater noise when reversing propulsion or using thrusters the two hydrophones should be located at least five meters from each other in the fore and aft plane. It is also recommended to install the two hydrophones with a slightly different tilt angles so that a larger vertical sector may be covered.

Vessels equipped with a bowthruster or bulbous bow can install the first hydrophone forward of the bowthruster on the bulbous bow and the second aft of the bowthruster.

→ See figure 99 on page 95.

Dual hydrophone installations may be either keel mounted or installed in free-standing blisters.

Dual hydrophone horizontal coverage areas

When the seine is normally located forward of the starboard beam when pursuing the following information should be taken into consideration:

- When the seine is pursed in the sector from approximately 000^ to about 130^ relative to the bow, the fore-most hydrophone should be installed at an angle of 50^ and the after 90^ to the vessel's centre line.

Figure 103 - Horizontal coverage area of a dual hydrophone installation

- Should special circumstances require coverage outside the standard 000^ to 130^ sector the hydrophones may be installed accordingly.

Dual hydrophone vertical coverage area

When the seine is normally located forward of the starboard beam when pursuing the following information should be taken into consideration:

•The optimal tilt angle for dual hydrophone installations is derived in the same manner as a for single hydrophone installations. Consult the section on Tilt angle for more information.

•The hydrophones should be tilted so that the most important part of the seine is adequately covered. Tilting the forward hydrophone -25^ and the after -15^ will provide proper coverage in most instances.

→ See figure 104.

Figure 104 - Vertical coverage area of a dual hydrophone installation

- Tilt should be no less than - 15^ in most instances with the optimal tilt angle depending on the size (length/depth) of the seine in use.

- Heeling of the vessel after the seine is set must be taken into consideration when calculating the tilt angle.

11.4 Portable hydrophone

A portable hydrophone has been developed to be used temporarily until a fixed hydrophone can be installed at the vessel's next dry docking. Unlike permanently mounted units, the portable hydrophone has an omni-directional beam. It can also be lowered below the level of high underwater noise and air bubbles generated by the main propeller and bow/sternthrusters which can block reception of hull mounted units. The hydrophone's cable is 50 meters long and sheathed in polyurethane providing robust external protection to compliment its 150 kg tensile strength.

When the seine is normally located forward of the starboard beam when pursuing the following information should be taken into consideration:

•The portable hydrophone is to be deployed over the port side of the vessel, midships, as far away from bow or sternthruster(s) used when pursuing as possible.
- Note that the portable hydrophone's location is opposite to that of a permanently mounted unit. When pursuing to starboard the hydrophone is normally lowered over on the port side of the vessel.

→ See figure 105.

Figure 1005 Po Portable hydrophone

• The hydrophone cable should be made fast to the vessel's bulwarks.
• Sharp edges that could damage the hydrophone cable insulation should be avoided and the cable lying on deck should not be walked on.
  •The hydrophone cable should not be knotted and kinking must be avoided.
  •The hydrophone should be lowered deeper than the vessel's keel.
• Special care should be taken so that the hydrophone or cable do not become fouled in the main propeller, thrusters or gear.

Storage

The portable hydrophone and cable should not be left on deck when not in use and stored with the following general precautions:

• Cleaned with fresh water after use.
• Care taken so that the cable does not chafe due to motion of the vessel.
• Contact with sharp edges that could damage the hydrophone cable insulation avoided.
  •The hydrophone cable should not be knotted or kinked.

11.5 Installation precautions

Caution!

The following precautions must be observed. Failure to do so can result in damage to the hydrophone which may rendering the PI30 Purse seining system inoperative.

1 Observe the maximum allowable torque warning of 5 Nm when tightening the hydrophone studs.
2 Use only M8x30 (reg. no. 560-095360) socket countersunk head screws for mounting the hydrophone.
3 Secure threaded hydrophone hardware with Loctite™ 270 or the equivalent.
4 Do not paint the hydrophone.
5 Do not sand- blast, power or steam wash the hydrophone.
6 Do not scrape the hydrophone with metal or other hard objects that may damage the polyurethane sheathing.
7 Do not strike the hydrophone.
8 Do not expose the hydrophone to harsh chemicals.
9 Do not perform hot work in the vicinity of the hydrophone.
10 Do not lift the hydrophone by its cable.

11.6 Cable layout

General

The following information is a general description of installation requirements for PI30 system cables. These instructions must be used together with the applicable cable plans.

Note!

All cable connections and related installations must be made in accordance with the guide-lines set forth by the vessel's classification society.

→ See figures 106 and 107 on pages 104 and 105.

Notes

The following notes refer to the PI30 cable plan:

Caution!

Use a multimeter to check for continuity. DO NOT subject the PI30's wiring or related components to high voltage.

Note 1 - Local supply

Note 2 - The hydrophone is delivered with a 22m long cable that may be spliced if necessary. Junction boxes made of metal must be grounded. Cable shielding must be continuous, it is terminated in the cabinet and must not be grounded in the junction boxes. The cable consist of six individual wires and a shield, only two of the wires (YE and R) are used. The topmost wires (BK, BL, and GN) are not to be connected. Simrad recommends running the cable between the hydrophone and PI30 cabinet through metal conduit to minimize electrical interference.

Note 3 - After making the connection, check continuity between the plug and the wires in the hydrophone's cable with the transducer selector in the forward and aft positions as follows:

• PiRirl 1to the red wire.
• Pin 7 to the yellow wire.
- Shielding is connected with pin 4, not grounded.

Note 4 - The portable hydrophone is delivered with a 50m stretch-proof cable (150kg tensile strength) consisting of a twisted pair, connected to a 10m PVC sheathed cable equipped with a seven pin plug for direct connection to the PI30 cabinet. If necessary the PVC sheathed cable may be spliced. Use a junction box constructed of mental which is grounded. The hydrophone cable's shielding is terminated at the plug and must not be terminated at the junction box.

Note 5 - Refer to the respective installation instruction for the connection of an echo sounder transducer.

Note!

The PI30's echo sounder is designed for use with a high-impedance ceramic traducers, it may be therefore necessary to employ a matching transformer should a low-impedance transducer is used.

Note 6 - Selection between the forward and aft hydrophones can be accomplished using a two-poll switch (Simrad reg. no. 351-078450 or equivalent). Cable shielding must be continuous, it is terminated in the PI30 cabinet and must not be grounded in the junction box or transducer selector.

Note 7 - Terminal numbers refer to Simrad's hydrophone selector (forward hydrophone, position 1/5; aft hydrophone position 3/7).

Note 8 - If an optional echo sounder transducer is installed, the PI30 becomes a fully functional echo sounder with the ability to superimpose sensor data over the echo sounder display for comparison.

14 GLOSSARY OFF TERMS

Alarms - can be activated when the PI30 detects a target above (shallower than) the minimum set alarm depth or below (deeper than) the maximum set alarm depth. The system allows alarm depths to be set individually and enabled or disabled as necessary.

A-Scope - a method of displaying echo sounder information where echoes are displayed in a bar-graph format. Stronger echoes may be differentiated from weaker by colour and width which corresponds to the strength of the return.

Colour threshold - a function that allows noise and weaker targets normally represented by blues and greens not to be shown by the selectively eliminating such colours from the display.

Configuration - are the setup parameters which allow the PI30 to be tailored to specific needs. The majority of displayed information including: units of measure, colours, language, scroll speed, window selection and other functions may be changed to suit a particular situation.

Default - initial setup parameters programmed by the factory.

Echogram background colour - the LCD background colour may be set to be black or white. Black is normally selected for night time operation.

Echo sounder frequency - may be set to either 200 kHz or 50 kHz employing narrow (15°) and wide (45°) transmitter beams respectively. For general purpose use the 200 kHz frequency offers optimum discrimination. The 50 kHz frequency is more effective when searching a wider area, determining bottom condition or operating at maximum depth.

Event marker - superimposes a vertical marker on the LCD at the location of the current ping to indicate for example a school of fish.

Expansion (zoom) - provides an enlarged view around a specified depth and may be adjusted in as required. The area near the bottom or variable range marker may also be magnified by using Bottom and VRM expansion functions respectively.

Gain - controls the PI30's sensitivity. Increasing the gain provides better return from smaller and deeper targets. Excessive gain will fill the LCD with unwanted targets known as “noise” and should be set to just below this point.

Interface - the electronic connection of one or more pieces of equipment allowing them to share data.

LOG speed calibration - the PI30 is calibrated at the factory to receive 19000 pulses per nautical mile using a paddle-wheel type log. Due to hydrodynamic differences between various installations this figure may have to be changed. The correct pulse rate may be calculated using the following equation:

$$ 1 9 0 0 0 \times \frac {S T W}{S O G} = P u l s e s / n m $$

STW= Speed Through Water from the vessel's speed log.

SOG= Speed Over Ground from the vessel's GPS.

Measurement units - in=the=range=display=are=in=either=meters, feet=or=fathoms.

MENU - an=on=screen=display=of=PI30's=functions=and=options navigable=using=the=cursor.

NMEA - The National Marine Electronics Association is a group of=equipment=manufactures=responsible=for=adopting=NMEA 0183=as=a=standard=for=interfacing=marine=electronics.

Note!

If the White line feature is activated when the Range start function is set at a water depth deeper than the actual depth, a continuous reset sequence will commence. The unit will continue to reset itself until the actual water depth exceeds the depth entered for the Range start function. Should a continuous reset situation arise and the vessel not be travelling toward deeper water, the transducer cable must be disconnected allowing the Range start depth to be changed to zero or a depth that will not result in the unit continuously resetting itself.

Scroll speed - is the rate of movement targets travel from right to left across the LCD. It may be adjusted to show a longer "history" if required.

Scroll synchronization - the screen can be updated on the basis of time or distance (when data from last ping appears on the display).

Signal threshold - removes unwanted noise using an automatically controlled threshold level. This function should be used with caution due to the possibility that small fish and other objects may be eliminated from the display.

Transducer - is the under water element of the system that both sends and receives acoustic signals which are used to determine the depth of objects.

TVG - Time Varying Gain - makes corrections for the majority of energy loss and absorption that occurs when sound waves pass through (sea) water. When making a selection in Presentation setup the best choice is normally Bottom 20logR. In shallower water the setting Fish 40logR gives a stronger return, but is more susceptible to surface noise.

White line - places a white or black line at the same depth as the sea floor shown on the LCD. By removing four pixels just below this line, targets that may have been obscured by the bottom are more easily identifiable.

VRM - Variable Range Marker is a controllable horizontal black line on the LCD that when oriented over a target displays its depth on the left side of the screen.
