Shutdowns And Alarms; Spare Parts - Northern Lights OM944W3 Operator's Manual

SHUTDOWNS AND ALARMS

1. Your unit is fitted with a system to protect it from
high water temperature, low oil pressure, and high
exhaust temperature.
a. Generator sets have shutdown systems to stop
the engine. They have no warning horns.
b. Other alarms and shutdowns are available as
optional equipment.
NOTE: If your unit is equipped with optional
shutdowns and alarms, do not rely on your
warning or shutdown system to the exclusion
of careful gauge monitoring. Watching your
gauges can prevent damage to the unit and
dangerous power losses.
2. Do the following when your warning or shutdown
system is activated:
a. Engage the preheat switch to check the
temperature gauge.
b. If above 205°F (96°C), use the Troubleshooting
Guide on page 25 to isolate the cause of the over-
heat.
CAUTION: Do not remove the water fill
cap of an overheated engine. Escaping high
temperature steam can cause severe burns. Allow
the engine to cool and then remove the cap slowly
using protective clothing.
c. Make repairs and restart after the temperature
gauge registers below 200° F (94° C).
d. Watch the temperature gauge regularly and
turn off the unit if the temperature rises above
205° F (96° C). Repeat troubleshooting.
3. If shutdown is activated and the temperature gauge
shows temperature within normal temperature range:
a. This shutdown could have happened because
of a too high exhaust temperature. This could
have been caused by a damaged impeller or a
partially blocked sea water strainer. Check the sea
water strainer first. If it is clear, then check the
condition of the sea water pump impeller.
b. Check the engine crankcase oil level.

Operating Procedures
c. If the oil level is low, fill with recommended
lubricating oil and restart. Watch the oil pressure
gauge carefully and shut off the engine if it does
not show a normal reading (20-60 PSI) after a
few seconds of operation.
d. If the oil level is normal, DO NOT restart the
engine. Call your dealer for assistance.
