TP-5606 6/02 Controller Troubleshooting 5-3
Stopping
A normal stop is initiated by rocking the Start/Stop
Switch on the controller front panel to the Stop position
and then releasing the switch. Holding the switch in
the Stop position energizes the C1 relay, causing
further, unnecessary heating of the intake manifold.
In the Stop position, the Start/Stop switch provides a
ground through two blocking diodes to energize the K4
relay (LED4 lights). The normally open K4A contacts
then close, latching the K4 relay in an energized
condition.
At the same time, normally closed K4B contacts open to
de-energize the FP (fuel pump) motor, the K25 relay,
and the K30 relay. The normally open K30 relay contacts
open to de-energize the 12 VDC fan for the remote
radiator. The normally open K25 contacts open to
de-energize the FS (fuel) solenoid, turning off the flow of
fuel. With the fuel supply and fuel pump both turned off,
the engine turns off.
When the engine turns off, the generator output decays
and causes relays K1 and K5 to de-energize (LED1 and
LED5 go out). The normally open K1D contacts then
open, de-energizing the K2 relay (LED2 goes out).
When the K2 relay de-energizes, the normally open K2
contacts open to interrupt power to the remaining
controller relay circuits, including relay K4. As a result,
thelatch-upoftheK4relayisbrokentoreturnthe
controller circuits to a normal prestart condition.
