PowerBox Systems SparkSwitch RS Instruction Manual page 2

The SparkSwitch RS is a compact, high-performance ignition switch featuring
rotational speed (RPM) monitoring and optional voltage regulation for 6V igniti-
on 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 par-
allel 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 vol-
tage 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.
