Engine System - Petrol (Gasoline) 206Service Manual – Haram Captor II
Normal Running
• When the key is released to the “run” position, the main machine controller turns off the voltage to the
crank request circuit. This de-energizes the crank request relay and removes power from the starter
solenoid.
• The rest of the circuit remains unchanged.
Engine RPM Control
The Woodward L-series actuator directly monitors the engine speed sensor input and adjusts the throttle
linkage to maintain the current target engine speed. If it is unable to maintain the speed within the desired
“window”, it will shut the engine down by removing the path to battery negative for the ignition request
relay through the actuator. Note that if the actuator loses the RPM signal while the engine is running, it will
shut the engine down. If the actuator never sees an RPM signal, it does not know that the engine is running
and has not tried but failed to control the RPM. Therefore it remains in a “cranking mode” and does not shut
the engine down.
The main machine controller communicates the desired engine speed mode to the actuator via the Throttle 1
and Throttle 2 wires. It either sends out 0v or 12v on each wire, depending on the desired speed mode.
