Engine System - Petrol (Gasoline)206Service Manual – H aram Captor IINormal Running• When the key is released to the “run” position, the main machine controller turns off the voltage to thecrank request circuit. This de-energizes the crank request relay and removes power from the startersolenoid.• The rest of the circuit remains unchanged.Engine RPM ControlThe Woodward L-series actuator directly monitors the engine speed sensor input and adjusts the throttlelinkage 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 requestrelay through the actuator. Note that if the actuator loses the RPM signal while the engine is running, it willshut the engine down. If the actuator never sees an RPM signal, it does not know that the engine is runningand has not tried but failed to control the RPM. Therefore it remains in a “cranking mode” and does not shutthe engine down.The main machine controller communicates the desired engine speed mode to the actuator via the Throttle 1and Throttle 2 wires. It either sends out 0v or 12v on each wire, depending on the desired speed mode.Speed Mode Engine Speed Throttle 1 Throttle 2Idle 1700 RPM 0 0Run 2500 RPM 0 12vMaximum Power 2700 RPM 12v 12v10AIGN.
