8.14.2 Fault Shutdown Senders/Switches
Check the senders/switches on the engine by
performing the following tests. If the sensor does not
function as described, replace it.
Hazardous voltage.
Can cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
areinplace.
Moving parts.
WARNING
Servicing the generator set when it is operating. Exposed
moving parts can cause severe injury or death. Keep
hands, feet, hair, clothing, and test leads away from the belts
and pulleys when the generator set is running. Replace
guards, screens, and covers before operating the generator
set.
Short circuits. Hazardous voltage/current can cause
severe injury or death. Short circuits can cause bodily injury
and/or equipment damage. Do not contact electrical
connections with tools or jewelry while making adjustments or
repairs. Remove all jewelry before servicing the equipment.
Low Oil Pressure (LOP) Sender
Disconnect the low oil pressure sender and use an
ohmmeter to measure the resistance of the sender. The
sender resistances varies with pressures and should be
within the values shown in Figure 8-24. If the resistance
is very low or very high, replace the low oil pressure
sender.

Seawater Pressure Switch
See Figure 8-25 for the seawater pressure switch
location. Remove the seawater pressure switch and
install a pressure gauge to verify that the seawater
pressure is within the range specified before testing or
replacing the seawater pressure switch.
To test the seawater pressure switch, reinstall the switch
and start the generator set. If the unit shuts down,
disconnect lead 87 from the seawater pressure switch
and reset the controller. Restart the generator set and
verify that it does not shut down. A successful restart
indicates a bad seawater pressure switch. Replace the
seawater pressure switch if the calibration pressure (or
opening adjustment range) is not 0.5 ±0.2 psi.
