DocumentDocumentInstruction Manual sparkswItch RS The SparkSwitch RS is a compact, high-performance ignition switch featuring rotational speed (RPM) monitoring and optional voltage regulation for 6V ignition systems. The SparkSwitch RS enables the user to switch the ignition on and off conveniently from the transmitter. The switched state can be checked at any time using the external LED or a telemetry status message. These features of the SparkSwitch RS enhance operating safety as well as simplifying the handling of petrol engines. In an emergency - such as the failure of a throttle servo - the SparkSwitch RS can be used to stop the engine quickly. An important feature is galvanic separation between the receiving system and the ignition system. The switching process as well as RPM feedback from the ignition unit are optically isolated from the receiver. This ensures that a fault in the ignition system shielding, or any other defect, cannot cause interference to the sensitive receiving system. The RPM (rotational speed) monitor input can be connected directly to the Tacho output of the ignition unit - if present. If your ignition system does not include a Tacho socket, we can supply a separate sensor which can be connected in parallel with the Hall sensor. The RPM data can be transferred to any of the current telemetry systems: the SparkSwitch RS automatically detects the system in use, eliminating the need for adjustments using the USB interface. The SparkSwitch RS can be supplied in either of two variants: with or without voltage regulation. The regulated variant reliably reduces the input voltage (max. 9.0V) to 6.0V. The version without voltage regulation passes the full voltage (max. 13.0V) through. 2 PowerBox-Systems - World Leaders in RC Power Supply Systems Features · Optical separation between the receiving system and the ignition system · External LED switch status indicator · Regulated (6.0V) or pass-through output voltage · RPM monitor for all current telemetry systems · Telemetry function for PowerBox, Jeti, Futaba, Graupner, Multiplex, Spektrum, JR · Failsafe mode · Machined aluminium heat-sink · Compact, low-profile format 1. CONNECTIONS The connections are clearly labeled on the SparkSwitch RS; the following describes them in detail: PWM/BUS: The PWM socket is not needed if you are using a PowerBox, Jeti, Futaba or Spektrum radio control system, as the SparkSwitch RS receives its switching information directly via the telemetry servo bus. By default the SparkSwitch RS is set to channel 12 for switching the ignition on and off. With these systems all you have to do is connect the unit to the receiver using a patch lead. All other systems require two patch leads: one connection to switch the SparkSwitch, and one for the telemetry. · PowerBox P²-BUS: connect the BUS input to the P²-BUS on the receiver · Jeti Ex-BUS: connect the BUS input to an EX-BUS output on the receiver · Futaba S.BUS2: connect the BUS input to S.BUS2 on the receiver www.powerbox-systems.com 3 · Spektrum SRXL2: connect the BUS input to SRXLS2 on the receiver · Graupner, Multiplex, JR and other systems: connect the PWM input of the SparkSwitch RS to a servo socket on the receiver. The BUS input of the SparkSwitch RS should also be connected to the receiver's telemetry output. Battery Connect the ignition battery to this socket. The centre pin is Positive, both outer pins are Negative. This arrangement eliminates the possibility of reversed polarity even if you connect the plug the wrong way round (turned through 180°). It is essential to use a separate battery for the ignition system. Do not take the current from the receiver power supply, as this would negate the galvanic separation of the two power circuits. Ignition Connect the ignition unit to this socket. The centre pin is Positive, both outer pins are Negative. This arrangement eliminates the possibility of reversed polarity even if you connect the plug the wrong way round (turned through 180°). RPM If your ignition unit features a Tacho output, then it can be connected directly to this socket. For other ignition systems a separate sensor is available which derives the rotational speed from the Hall sensor. The RPM output also provides power to external sensors, which means that other types of rotational speed sensor - such as optical systems - can also be connected. LED The external LED is connected directly to the power output for the ignition unit, and is therefore a reliable indicator of the switched status. 4 PowerBox-Systems - World Leaders in RC Power Supply Systems 2. SETTINGS AT THE TRANSMITTER You must assign a dedicated channel at the transmitter for switching the ignition switch. The travel of the switched channel at the transmitter should be -100% to +100%; the switching threshold is located at around +50%. If you are using a system which supplies the switching signal via the telemetry bus (PowerBox, Jeti, Futaba and Spektrum), the simplest method is to use channel 12, as this is the default setting on the SparkSwitch RS. If this channel does not conform to your preferred transmitter layout, you can change the channel from the transmitter if you are a PowerBox (Telemetry menu) or Jeti (JetiBox MX) user. If you use a Futaba or Spektrum system, you can change the channel using PowerBox Terminal and the USB Interface. If you are using a Multiplex, Graupner or JR system, simply connect the PWM output to the assigned channel at the receiver. No other settings have to be changed, as the SparkSwitch RS detects the telemetry system automatically. 3. INSTALLATION Install the SparkSwitch RS close to the ignition unit. Under no circumstances install the unit close to the receiver. The cables to the ignition unit should be as short as possible, and should not be bundled together with other cables which feed into the receiving system - such as the throttle servo lead. In contrast, the cables to the receiver can be any length you like, as they are "clean" thanks to the optical isolation from the ignition system. www.powerbox-systems.com 5 4. IGNITION BATTERY Any type of ignition battery can be used: LiPo, LiIon and LiFe up to 3S, 8S NiCd or NiMh. When connecting the battery, it is essential to maintain correct polarity! Reversed polarity will destroy the electronics in the SparkSwitch RS. The regulated version of the SparkSwitch RS incorporates an integral regulator which basically limits the voltage to 6.0V. This makes the SparkSwitch RS suitable for all ignition units whose label states 4.8V and 6.0V. The unregulated version passes the full, unregulated input voltage (max. 13V) through, with low losses. This means: if you connect a 2S LiPo, the ignition unit is fed a voltage of up to 8.4V; with a 3S LiPo it is up to 12.6V. The ignition battery can be left permanently connected to the SparkSwitch RS. The current drain when switched off (1 A) is so low that the battery will not be discharged even over a period of months. 5. RPM DIVIDER / MULTIPLIER Depending on the type of RPM sensor you are using, it may be necessary to set up a divider or multiplier to obtain the correct rotational speed. PowerBox (Telemetry menu) and Jeti (JetiBox) users can set this directly from the transmitter; other systems require these settings to be changed using Terminal and the USB Interface. 6 PowerBox-Systems - World Leaders in RC Power Supply Systems 6.
