CONTROL PANEL (TYPE 5)
SYSTEMS OPERATION
Engine Does Not Start
If the engine does not start in approximately 30
seconds, overcrank timer (OCT) will let current flow to
overcrank indicating relay (OCR). Contact (OCR2)
closes to lock in the (OCR) relay and contact (OCR1)
opens to open the RR relay circuit. This de-energizes
run relay (RR) and magnetic switch (MS).
When run relay (RR) is de-energized, contact (RR2)
closes and contact (RR1) opens. Contact (RR2) closed
completes a circuit to shutoff solenoid (SS) until TDX
opens.
NOTE: TDR contact closes after 9 seconds
into the 30 second cranking cycle. The TDX
relay in turn energizes. This causes the TDX
contacts to close. The TDX contacts will
remain closed for 70 seconds after the end of
the 30 second cranking cycle.
Contact (RR1) open de-energizes arming relay (AR),
and overcrank timer (OCT).
When magnetic switch (MS) is de-energized, (MS)
contacts open. This de-energizes pinion solenoid (PS).
(PS) contacts open and de-energize starting motor (SM).
Overcrank indicating relaying (OCR) will give light.
To start the engine, do the steps that follow:
1.
Turn
engine
control
switch
(ACS)
to
OFF/RESET. This will open (ACS) contact (IS)
and de-energize overcrank indicating relay
(OCR). Contact OCR1 will close so that the run
relay (RR) can be energized.
2.
Turn the engine control switch to MANUAL or
AUTO if I contact is closed. If the engine does
not start in approximately 30 seconds, the
overcrank indicating relay will give light.
3.
Turn engine control switch (ACS) to STOP
position. Observe fault lights and turn ACS to
OFF/RESET. Correct the problem that caused
the engine not to start. Make reference to
TROUBLESHOOTING.
NOTE: If the engine can not be started or
stopped with the panel controls, check the
condition of circuit breaker (CB2). (There is
no visual indication of its condition). Press
to reset.
