Low Oil Pressure (LOP) Shutdown
Connect a jumper wire from the LOP switch (lead 13) to
the generator set ground. Start the generator set. Verify
that the generator set shuts down after approximately
25--35 seconds of operation. Remove the jumper wire
from the LOP switch and ground. Start the generator set
and run it for at least 25--35 seconds to verify that the
generator set does not shut down.
Overcrank Shutdown
Disconnect the starter motor lead at the starter solenoid
terminal and the fuel solenoid valve. Press the RUN
button on the controller. Observe that the generator set
simulates cranking for 15 seconds and then rests for 15
seconds. Check that the generator set shuts down after
the third crank/rest cycle.
High Engine Temperature Shutdown
Disconnect the harness (connector P5) at the engine
temperature sensor (CTS). See Figure 5-22 for the
CTS location. Connect a jumper wire across the
temperature sensor (CTS) connections in connector
P5. See Figure 5-23. Press RUN to start the generator
set. After 5 seconds, verify that the controller display
shows HE, indicating a high engine temperature fault. If
a Model RRT transfer switch is connected, the
generator set will run for 5 minutes in engine cooldown
mode. The display will alternate HE and COOL.
Press the OFF button on the controller and remove the
jumper wire. Start the generator set and verify that the
generator set does not enter the engine cooldown cycle
or shut down on an HE fault. Reconnect P5 to the CTS.
