9. DESCRIPTION OF DEVICE

General characteristics

The IUC 24 InterPuls is a control box equipped with a switching transformer used to supply power to the electrical pulsator with a 24 Vcc 8.4 A output at a maximum of 25°C.

It is capable of supplying power to a maximum of 24 pulsators (Front & Rear) divided in 4 channels (maximum of 6 pulsators per channel).

Every pulsator is equipped with two coils: one Rear and one Front controlled by duty-cycles programmable within a 10÷90 (90÷10) range and with a programmable frequency of between 30 and 260 pulsations/minute.

Maximum absorption of every coil: 3.6W at 24Vcc (absorption approximately 150mAcc).

Every channel must supply a maximum nominal of 1.8A (two coils simultaneously for 6 pulsators) and has a maximum power supply limit set by the controlling CPU of approximately 2.0A +10% -0%.

The device uses the classic switching technology and therefore absorbs the current with almost unitary power as per the norms in force in Europe (EN61000 and derivatives), United States and/or Japan (ex IEC555)

• Rapid response to rate of loading
- Reduced dimensions

The convertor is carried out at high frequency to reduce electrical component and packaging waste.

14. SWITCHING ON FOR THE FIRST TIME

First time procedure

WARNING

Before switching on, ensure that all the connections have been correctly installed as indicated in the paragraph - Errore. L'origine riferimento non è stata trovata.

- Switch the device on by turning the main switch on the control unit to the ON position.

Figure 26

- Wait until the control unit starts up and enters its normal operation cycle.

The following data are displayed

C1 RATE 60 PPM F 60/40 R 60/40

Menu

• Press the button and enter the password 1 3 2.
• Set the pulsation parameters as explained in paragraph 12.1 - Menu 1.1 & Menu 1.2 - Setup Pulsation Parameters SET1 and SET2 Pulsation Parameters.
• Once the pulsation parameters have been successfully set, press the

Menu

button until

the

stand-by

screen

returns

C1 RATE 60 PPM F60/40 R 60/40 II

- All the settings programmed are stored, even when the power supply is cut off.

15. SWITCHING ON AFTER THE FIRST TIME

Switching on after the first time

• Turn the switch on.
• For 20 seconds, the control unit shows the software version stored in the memory.
• The currently set pulsation parameters are loaded. This time prior to the starting of the pulsators allows optimum vacuum to be obtained in the system before the pulsators start up.

DATA RESTORED FROM EEPROM

• The message FROM EEPROM indicates that the control unit has loaded the set parameters correctly and that it will start up with the last set of parameters selected.
• Pulsation then starts up and the following message is displayed

C1 RATE 60 PPM F 60/40 R 60/40 I

• The alternating flashing of the two bars in the bottom right hand corner of the display indicates that the microprocessor is controlling the power transistor of the pulsators correctly.
• The message is displayed for 10 seconds on each channel and is repeated cyclically

Cont...

- By pressing the 📄 or 📋 button, it is possible to display the information relative to a specific channel, without having to wait for the automatic scrolling.

- In order to switch from the settings stored for SET1 to those stored for

SET2, hold down the

Set 1/2

button for at least 3 seconds.

NOTE : It is possible to switch from SET1 to SET2 both during the normal operation of the control unit and also from the programming menu.

- The SET1 and SET2 LEDs indicate which of the two sets of parameters is currently active.

NOTE : If the set is switched during the normal operation of the control, the display is immediately updated with the new pulsation parameters.

NOTE : When the control unit is switched on, the device starts operating in the last SET of parameters selected prior to being switched off and it reserves all the data programmed before it was switched off.

16. TROUBLESHOOTING AND ALERTS

16.1. No command to pulsators

Problem Encountered

No command to the pulsators; no pulsation on some of the pulsator channels

Checks to be performed

During the Stand-by condition, failure of one of the two flashing bars indicates a pulsator channel power failure.

Solutions

Contact Service immediately. A part of the system may not be receiving the pulsation command.

16.2. Excessive current

Problem Encountered

No command to the pulsators; no pulsation on some of the pulsator channels.

Checks to be performed

During operation, the normal Stand-by screen alternates with another indicating “SHORT CIRCUIT”.This happens when the current of a single section (F or R) of a channel exceeds the limit of 2.0A. The second line of the display shows which section of which channel is in overload condition (e.g.: F1=Front Channel 1, R4=Rear Channel 4). This channel is isolated from the load, i.e. it is no longer powered while all the other sections continue to work normally.Channel 1 F in overload or short circuit condition.If several overload/short circuit conditions occur at the same time, the control unit reacts by interrupting the pulsation command only on the channels affected by the problem and a message is displayed indicating which channels are affected by the failure.Channels 1, 3, 4 coil R in overload or short circuit condition.The control unit automatically eliminates the pulsation command in the faulty part of the system only.If the damage is temporary, the situation returns to normal and the message disappears; otherwise, the channel remains disabled until the control unit is switched off and then switched on again.

Solutions

Contact Service without delay. Do not use the channels affected by the problem for milking.There might be a problem in the electrical connections between the pulsators and the control unit.[DOWA]NOTE: The excess load condition can be maintained indefinitely without damage because the power transistors that feed the pulsators are protected against permanent short circuit.NOTE: The control unit verifies the short circuit or overload condition by attempting to restore the power supply to the pulsators 3 times at 6-second intervals. If, after the third attempt, the failure persists, the power supply is cut off until the control unit has been switched off and then switched on again.NOTE: The SHORT CIRCUIT message is associated with an intermittent buzzer.NOTE: In the event of multiple alarms, the message SHORT CIRCUIT alternates with the reporting of the other currently active alarms (WARNING LOW VOLTAGE and/or OPERATING HOURS TECHNICAL SUPPORT)

16.3. Memory error

Problem Encountered
The control unit is not operating correctly and one of the following messages is displayed:
NO DATA SAVEDIN EEPROM MEMORY	EEPROMERROR
Checks to be performed
Switch off the control unit and wait for 30 seconds before switching it on again. Check whether the error message is still displayed.
Solutions
Contact Service without delay.The message indicates the existence of errors in the memory of the control unit. These errors cancel the settings saved and delete the service hours stored by the machine.

16.4. Service control time exceeded

Problem Encountered

The control unit displays the following message:SERVICETIME OVERDUEThe message displayed is associated with an intermittent buzzer (0.5sec ON - 2sec OFF)

Checks to be performed

Ensure that, after 10 seconds, the display starts showing the operating parameters again.

Solutions

Contact Service immediately.When the operating time of the control unit exceeds the number of hours set for the next periodical check (default=5000 hours), each time the control unit is switched on a message will appear for 10 seconds reminding the operator to call Service for the periodical check of the equipment.NOTE: Only Service can cancel the alarm message by entering – by means of the appropriate password – the Menu 1.3 Timer

16.5. Low pulsator command voltage

Problem Encountered

The control unit displays the following message:WARNINGLOW VOLTAGEThis message alternates on the display with the normal message indicating that pulsator control is in operation (2sec ON - 10sec OFF)

Solutions

Contact Service immediately.The output voltage of the power supply unit requires adjustment.The microprocessor control works well even with very low voltages but some pulsators might NOT work properly with command voltages that are too low. An alarm signal sounds when the supply voltage of the pulsator drops below 21V.

17. MAINTENANCE

Checks to be performed

A specialised technician's visit is recommended for maintenance every 12 months in order to check the state of wear of the electrical and mechanical components of the Programming system
