Instruction Manual PrO
Dear customer, we are delighted that you have selected the SparkSwitch PRO from PowerBox-Systems. The SparkSwitch PRO is the logical development of the original SparkSwitch, which has been successful in the market since its introduction in 2008. The SparkSwitch PRO combines acknowledged reliability with new telemetry transmission options.
- External power-on LED - Power circuits isolated using IRDA light transmission - Two different switching modes - Telemetry function for PowerBox, Jeti, Futaba, Graupner, Multiplex, JR - Telemetry data includes battery voltage, current, consumed capacity, temperature and RPM - Failsafe mode - Stand-by current drain, ignition side: 60 µA - Weight: 16 g 2.
3. FIRST STEPS BEFORE USING THE UNIT 3.1. CONNECTING Complete all the electrical connections as shown in the wiring diagram above. The battery should be connected last. For safety reasons the external LED must always be connected. It should be installed in such a position that the external LED is clearly visible to the pilot at all times when the engine is being started. Caution: If the external LED is not installed, the pilot has no way of knowing whether the ignition is switched on or off.
3.4. IGNITION BATTERY All types of ignition battery can be used: LiPo, Li-Ion and LiFe up to 3S, NiCd or NiMH up to 5S. Take care to maintain correct polarity when connecting the battery, as reversed polarity will ruin the electronics in the SparkSwitch PRO. The unit’s integral regulator basically limits the voltage to 5.9 V, which means that the SparkSwitch PRO is suitable for all battery types such as 4.8 V, 6.0 V.
3.5. DEFINING THE SWITCH CHANNEL AT THE TRANSMITTER Normal mode: Switch position A is programmed to 0% at the transmitter, and is always the “OFF” position. Switch position B is programmed to +100% at the transmitter, and always switches the SparkSwitch “ON”. If no valid signal is present at the receiver, the SparkSwitch switches itself off. Ideally you should program the transmitter’s fail-safe function so that the SparkSwitch cuts the engine if the signal is lost.
switch off the SparkSwitch. Non-latching transmitter switches are ideal for this mode: pull the switch and release it in order to switch the ignition on; repeat the procedure to switch the ignition off again. If there is a loss of voltage on the receiver side, the SparkSwitch always switches off, and stores the last switched state, i.e. if the signal is restored, the SparkSwitch will either be “ON” or “OFF” according to its previous switched state.
- Jeti EX The SparkSwitch PRO must be set to use the Jeti telemetry system. This can be accomplished using the Terminal program or the Jeti USB adapter. Connect the SparkSwitch RX input to the receiver’s switch channel. The receiver’s Telemetry input must be set to JETI BOX. Connect the Telemetry output from the SparkSwitch to the receiver’s Telemetry input using the second patch lead. The telemetry data are displayed in the transmitter’s Sensor menu. - Futaba S.
- JR DMSS The SparkSwitch PRO must be set to the JR telemetry system. Connect the RX input on the SparkSwitch to the receiver’s switch channel, then connect the Telemetry output on the SparkSwitch to the receiver’s SENS input using the second patch lead. The telemetry data are displayed on the transmitter as F-PACK (V, C, A), Temp. and RPM. 3.7. INSTALLING THE TEMPERATURE SENSOR The temperature sensor is attached to the cylinder head using a ring-screw. This requires a 3.
supply and Tacho output are linked using a Y-lead. You will find detailed, illustrated instructions on the procedure for connecting the Tacho output in our PowerBox Support Forum. 4.
