Engine System - Petrol (Gasoline)205Service Manual – H aram Captor IICranking• When the main machine controller sees the 36v cranking request from the key switch, it sends out 12v onthe crank request circuit to the crank request relay winding. The other side of the winding is groundedthrough pin 9 of the actuator (as long as there is not a shutdown condition within the L-Series actuator).This energizes the crank request relay and battery power is passed through the contacts to the startersolenoid engaging the starter to turn the engine crankshaft. The starter motor power is also fed to thechoke solenoid which pulls the carburetor choke closed.• Once oil pressure builds up, the oil pressure switch opens.– The loss of ground through the oil pressure switch causes the low oil pressure shutdown relay to de-energize.◦ Battery power is then passed through the “closed at rest” contacts to the main machine controller asthe “engine run” signal and to the Woodward L series actuator pin 8. From this point on, the “runenable” signal to the actuator is maintained by the low oil pressure shutdown relay.◦ The same power is also passed to the power relay coil energizing the relay.− Battery power is then passed through the “closed when energized” contacts of the power relayback into the ignition request circuit and to the control relay winding, energizing the controlrelay.10AIGN.
