3. APPLICATIONS

The SAFETY-SWITCH LiPo and SAFETY-SWITCH LiPo TwinBatt are ultra-modern electronic switch harnesses / power supply systems. They are intended exclusively for use in modelling applications.

It is prohibited to use these devices for applications such as man-carrying aircraft or industrial equipment.

TwinBatt 4. SPECIAL FEATURES

SAFETY-SWITCH LiPo and SAFETY-SWITCH LiPo TwinBatt:

Electronic switch harnesses.
- Much more robust than conventional mechanical switches, as they are not susceptible to vibration, wear or contact corrosion problems.
- Extremely rugged plastic housing, large heat-sink for voltage regulator, high-flex connecting leads.
- Power supply for servos and receiver optionally from 2S LiPo or 5-cell NiXX battery.
- Linear IC-controlled stabilisation generates a stabilised output voltage of 5.5V , corresponding to a fully-charged four-cell NiXX battery. This ensures that the servos operate at constant speed and torque over the full period of operation - an important requirement for high-quality aerobatics.
- Battery connection via encapsulated MPX high-current connectors (M6 system).
- Two receiver connecting leads (UNI system) for maximum possible security, with double conductor cross-section and twice the number of electrical contacts.
- Three-colour LEDs provide constant visual four-stage indication of receiver battery voltage.
- Simple, carefully thought-out power-on procedure: an internal program ensures completely secure switching processes; it is impossible to switch the harness on or off accidentally.

The SAFETY-SWITCH LiPo TwinBatt also offers:

• High-performance integral battery backer, permitting the use of two receiver batteries ( 9.2.4).
• One sensor button for each power circuit, with security button. Each power circuit can be switched on and checked individually.
• Two linear voltage regulators - one for each battery input.
• Two electronic switches - one for each power circuit.
• Two voltage monitors for monitoring the two batteries.
• Two three-colour LEDs for four-stage display of the voltage of both batteries.
• Two minimum value (low voltage) memories, can be read out separately for each battery.

5. INTENDED APPLICATIONS / TYPICAL MODEL TYPES

5.1 SAFETY-SWITCH LiPo

Designed for use in small to medium-sized model aircraft of all kinds, e.g.:

Power models with wingspans up to around 1.8m/5kg all-up weight and 5-6 servos
- Model gliders with wingspans up to around 3.5m and 6 - 8 servos
- Model helicopters up to around .50 / 6S class
- Petrol engine ignition systems which are normally operated on the voltage of a four-cell NiXX battery

5.2 SAFETY-SWITCH LiPo TwinBatt

Designed for use in medium-sized model aircraft of all kinds, e.g.:

Power models with wingspans up to around 2.2m/5 - 8kg all-up weight and 5-6 servos
- Model gliders with wingspans up to around 5 m and 8-10 servos
- Model helicopters of around .50 - .90 / 8 - 10S class

Notes

The recommended model types should only be considered as a guideline. The maximum possible number of servos varies substantially according to the input voltage, the installation, the cooling of the switch, and the servo type and current drain.

The SAFETY-SWITCH LiPo and SAFETY-SWITCH LiPo TwinBatt are equipped with linear voltage regulators. The input voltage (approx. 8.0 V with 2S LiPo, approx. 6.5 V with 5 NiXX cells) affects the maximum possible continuous current (2.0 A with 2S LiPo / 5.0 A with 5 NiXX cells): the higher the input voltage, the lower the maximum possible continuous current:

Max. dissipated power P = (U BATT - UOUT) x I

Key to formula:

Max. dissipated power P: 5.0 Watts

U_BATT = battery voltage with 2S LiPo or 5 NiXX cells

U_OUT = 5.5 V , i.e. output voltage

I = cont. current: 2.0 A with 2S LiPo | 5.0 A with 5 NiXX cells

The maximum possible continuous current is largely determined by the size of the heat-sink and its cooling in the model.

If the switch harness heats up severely (more than 60^ ) when in use, you must assume that the servos are consuming a disproportionate current (power). If this happens, you should check the servos, the control linkages (excessive friction), pushrods, etc.

If the battery voltage falls below the regulator output voltage (5.5 V), then the full remaining voltage is switched through directly. The electronic circuit continues to work down to below 2.5 Volts.

6. INSTALLATION IN THE MODEL

The switch harness should be installed in a position where as much cooling air as possible can flow over it. For good cooling - and therefore for good performance - it is important not to cover the heat-sink, so that heat can be dissipated efficiently ( 5) .

The switch harness should be mounted in a position in the model where vibration levels are low.

The switch housing features two countersunk holes for mounting the unit.

7.3 Connection to the receiver

The SAFETY-SWITCH LiPo and SAFETY-SWITCH LiPo TwinBatt are connected to the receiver via the two leads which terminate in UNI connectors. These are compatible with the connectors used by most radio control system manufacturers (MULTIPLEX, HiTEC, robbe/Futaba, Graupner/JR, ...).

1. Connect one of the two leads to the receiver socket for the receiver battery.
2. Connect the second lead to the second receiver battery socket on the receiver, or to any vacant servo socket. The second battery lead increases operational security, as the current is distributed over two leads and a higher number of electrical contacts.

When you are connecting the unit to the receiver, please ensure correct polarity (pin assignment), especially with other makes of receiver:

Blue wire = negative (-), red wire = positive (+).

7.4 Connecting the receiver battery or batteries

SAFETY-SWITCH LiPo

Locate the battery lead terminating in an M6 connector (M6 plug # 8 5213, M6 socket # 8 5214), and connect a two-cell LiPo battery or a five-cell NiXX battery to it with correct polarity.

SAFETY-SWITCH LiPo TwinBatt

Locate the two battery leads terminating in M6 connectors (M6 plug # 85213, M6 socket # 85214), and connect a two-cell LiPo battery or a five-cell NiXX battery to each with correct polarity.

The two batteries must be of identical type and capacity!

When connecting the receiver battery or batteries, take care to maintain correct polarity (pin assignment). Blue wire = negative (-), red wire = positive (+).

Caution: connecting the unit with reversed polarity will immediately ruin the regulator IC in the switch!

Ensure that all the components powered via the switch harness (servos, gyro, speed controller,...) are approved by the manufacturer for use on a voltage of 5.5V .

Batteries must be of adequate capacity

To power your receiving system you should only use low-impedance batteries of the highest quality. We recommend the use of batteries with a capacity of at least 1500 - 2000 mAh. For larger models batteries of up to 3000 mAh are more appropriate. At the end of the flight the batteries should still retain at least 1/3 of their full capacity. Never discharge batteries completely!

8. SAFETY-SWITCH LIPO:

CONTROLS, DISPLAY ELEMENTS,

USING THE UNIT FOR THE FIRST TIME

8.1 Controls and display elements

The only control on the SAFETY-SWITCH LiPo is a single button (sensor button); the unit is therefore extremely easy to use.

The button simply passes on the switching signal to the electronic switch. The button's function plays no part in actually switching the current.

Once switched on, the self-latching electronic switch always remains at the "ON" setting. Even interruptions in the voltage (e.g. intermittent contact, poor leads, failing battery solder tags) while the system is switched on have no effect on the status of the switch.

This button is also used for setting the battery type you wish to use.

The multi-colour LED acts as a constant visual four-stage indicator of the voltage of the receiver battery.

8.2 Using the device for the first time

8.2.1 Switching on and off, LED colours

Switching on:

1. Connect the battery to the switch harness
2. Hold the sensor button pressed in for about 0.5 sec.

LED glows orange

1. Release the sensor button, and immediately press it briefly a second time
   LED glows green* (assuming the battery is fully charged): the SAFETY-SWITCH LiPo is switched on

2. The LED may also glow orange, red, or flashing red, according to the battery's state of charge (see below).

Switching off:

1. Hold the sensor button pressed in for about 0.5 sec.
   LED glows orange
2. Release the sensor button, and immediately press it briefly a second time
   LED goes out: the SAFETY-SWITCH LiPo is switched off

Note

The requirement to press the button twice when switching on and off eliminates the risk of operating the switch accidentally.

LED colours:

The three-colour LED indicates the current voltage of the battery:

• Green: Battery voltage satisfactory
  Orange: Battery approximately half-empty
  Red: Battery flat
• Flashing red: Maximum alarm stage!

Note

The switch harness is in the 'ON' state when supplied. When you connect a battery after purchasing the unit, the three-colour LED will immediately light up, indicating the current state of the battery (default setting = LiPo battery!).

Tip

When the RC system is switched on prior to flying, we recommend that you "stir the sticks" to move the servos, and check that everything is in order when the battery is under load. The colour of the LED is a useful indicator if the battery is not suitable (too small, too flat) for the servos installed in the model.

8.2.2 Setting the battery type

If you need to change the battery type setting, this is accomplished using the sensor button.

1. The default setting is for a two-cell LiPo battery. If you wish to use this battery type, no further adjustments are required.

2. If you wish to use a five-cell NiXX battery, you must set the voltage monitor to this battery type.

To switch to the NiXX battery setting:

Connect your preferred battery to the unit (the SAFETY-SWITCH LiPo must already be switched on (see 8.2.1)).

Hold the sensor button pressed in:

a) First the LED glows orange
b) Then the LED changes to red
c) Finally the LED flashes green once

Release the button: the set battery type is now LiPo

Alternatively wait until the LED flashes green twice

Release the button: the set battery type is now NiXX

9. SAFETY-SWITCH LIPO TWINBATT:

CONTROLS, DISPLAY ELEMENTS,

USING THE UNIT FOR THE FIRST TIME

9.1 Controls and display elements

The push Buttons on the SAFETY-SWITCH LiPo TwinBatt are marked "SET", "I" and "II".

The sensor buttons do not switch the current for the receiver and servos. The actual switching process is carried out by the two independent electronic switches in the SAFETY-SWITCH LiPo TwinBatt.

The switch harness is equipped with an LED power-on indicator for both power circuits: if one battery is switched on, the associated multi-colour LED lights up. If both batteries are activated, both LEDs light up.

The central red LED is used in conjunction with the power-on and power-off process, and when setting the battery type in use.

9.2 Using the device for the first time

9.2.1 Switching on and off, LED colours

Switching on:

1. Connect the two receiver batteries to the SAFETY-SWITCH LiPo TwinBatt

2. Hold the SET button pressed in

The red LED glows

1. Continue to hold the SET button pressed in, then press the buttons I and II briefly in turn

The left and right LEDs light up: the SAFETY-SWITCH

LiPo TwinBatt is switched on

1. Now release the SET button

Switching off:

1. Hold the SET button pressed in

The central LED glows red

1. Continue to hold the SET button pressed in, then press the two buttons I and II briefly in turn

All the LEDs go out: the SAFETY-SWITCH LiPo Twin Batt is switched off

3) Now release the SET button

LED colours:

The switch harness is equipped with two independent voltage monitors. The current voltage of the batteries is assigned to the two multi-colour LEDs (right and left LED) in the switch housing. The LEDs indicate the current voltage of the two batteries in four stages:

• Green: Battery voltage satisfactory
  Orange: Battery approximately half-empty
  Red: Battery flat
• Flashing red: Maximum alarm stage!

Tip

When the RC system is switched on prior to flying, we recommend that you "stir the sticks" to move the servos, and check that everything is in order when the batteries are under load. The colour of the LED is a useful indicator if the battery is not suitable (too small, too flat) for the servos installed in the model. Both power circuits can be switched on and off separately using the push Buttons I and II. This method of switching enables the user to check each power circuit or battery separately:

1. Switch one power circuit on, "stir the sticks" to move the servos, and check that the battery voltage does not collapse.
2. Switch the first power circuit off again.
3. Switch the second power circuit on, and carry out the same check as described under 1.
4. If everything is in order, switch the first power circuit on again.

You now have genuine double security.

9.2.2 Setting the battery type

If you need to change the battery type setting, this is accomplished using the sensor button marked SET.

1. The default setting is for a two-cell LiPo battery.

If you wish to use this battery type, no further adjustments are required.

1. If you wish to use five-cell NiXX batteries, the voltage monitors have to be set to this battery type.

To switch to the NiXX battery setting:

Connect both NiXX batteries (the SAFETY-SWITCH LiPo TwinBatt must already be switched on (see 9.2.1)).

The left and right LEDs now both flash red, since the default setting for the voltage monitor is for LiPo batteries. To re-set the voltage monitor to five-cell NiXX batteries the program has to be changed; the change affects both batteries.

This is accomplished by holding the SET button pressed in:

a) The central LED now starts to glow (red), in addition to the left and right LEDs
b) After a further period of about five seconds all the LEDs go out briefly
c) The central LED flashes red once

Now release the SET button: the set battery type is LiPo
If you continue to hold the button pressed in, the central LED flashes red twice
At this point - and not before - release the SET button: the voltage monitor is now set to five-cell NiXX batteries

9.2.3 SAFETY-SWITCH LiPo TwinBatt: minimum value memory

For even better monitoring of the power supply, the SAFETY-SWITCH LiPo TwinBatt features a supplementary minimum value memory (low voltage memory).

This low voltage memory records any voltage collapses in one or both batteries during the flight just completed.

Calling up the minimum value memory after the flight:

Before switching the system off, hold both sensor buttons I and II pressed in simultaneously.

The colour of the left and right LEDs now indicates to you the minimum voltage values for each battery since the last time the system was switched on.

Note

Switching the power supply off resets both memories (RESET). Next time you switch on, the recording process starts again.

9.2.4 SAFETY-SWITCH LiPo TwinBatt: battery backer function

The SAFETY-SWITCH LiPo TwinBatt features an integral battery backer which enables you to use two receiver batteries for enhanced security.

If one battery should fail, the second pack assumes the role of power supply for the receiving system. Under normal circumstances the current load of the entire receiving system in the model is shared by two batteries.

The system is of duplicated construction, i.e. each of the two power supply paths contains its own electronic switch, a separate voltage regulator and a separate voltage monitor for each of the two batteries.

This lay-out makes it easy for you to identify a defective receiver battery, or a pack nearing the end of its useful life, and replace it in good time.

10. S AFETY "HOLD" MODE

If a problem occurs - overheating, component failure, intermittent contact in the leads or battery - while the system is switched on, the SAFETY-SWITCH LiPo and SAFETY-SWITCH LiPo Twin

Batt always remain switched on. The program also invokes a safety "hold" mode if the user carries out the power-off procedure incorrectly; in this state it is no longer possible to switch the system off using the button.

If this should occur, please disconnect the battery from the switch harness and wait for at least thirty seconds. Reconnecting the battery re-starts the program, and the switching function will be available once more.

If this should occur often, please check the condition of your batteries.

11. I F THE SYSTEM IS NOT TO BE USED FOR A LONG PERIOD: DISCONNECT THE RECEIVER BATTERY

When the system is switched off with a battery still connected, what is known as a "stand-by" circuit is active.

In this state an idle current of around 5.0 A (per battery) flows; this is lower than the self-discharge rate of any battery.

We recommend that you disconnect the battery or batteries from the SAFETY-SWITCH LiPo / SAFETY-SWITCH LiPo TwinBatt if you know you will not be flying your model for a long period.

12. U SING LIIO AND LIFE BATTERIES

If you have connected two-cell Lilo batteries (Lilo = Lithium-iron) with a nominal cell voltage of 3.6 V to the switch harness, you should leave the unit set to the default battery type "LiPo" ( 8.2.2 or 9.2.2).

It is also possible to use two-cell LiFe batteries (LiFe = LithiumFerrite) with a nominal cell voltage of 3.3 V. In this case you should change the setting of the switch harness to the battery type "NiXX" ( 8.2.2 or 9.2.2).
