SHUTOFF AND ALARM SYSTEMS
SYSTEMS OPERATION
water temperature switch (2) and through switch (4) to
the fuel shutoff solenoid. When the engine stops, engine
oil pressure will become less than the setting of the oil
pressure switch. The N.O. switch will open and stop the
flow of current to the time delay relay.
This will start the time delay relay timer. After 70
seconds, switch (4) will close and current will again flow
to the fuel shutoff solenoid.
If engine oil pressure gets less than the setting of the
oil pressure switch, the’ N.O. switch will open.
This will stop current flow through switch (4) to the fuel
shutoff solenoid. The current flow will stop to the time
delay
relay
and
start
the
time
delay
relay
timer. After 70 seconds, switch (4) will close and current
will again flow through the fuel shutoff solenoid.
NOTICE
To help prevent damage to the engine, find and
correct the problem that caused the engine to shut
off before the engine is restarted.
NOTE: To help prevent discharge oft’ the batteries when
the engine is shut off, a switch can be installed to turn off
the current to the shutoff solenoid.
