Shutdowns And Alarms - Northern Lights M80A13S Operator's Manual

3. Fill the fuel tank to minimize possible water
condensation problems. Filling tanks at end of day
drives out moisture-laden air.
4. For Heat Exchanger Engines: If the engine will
be subjected to temperatures at or below 0°C(32°F),
open the sea water pump end cover to drain the sea
water from the system to prevent freezing. The sea
water pump will require priming before starting the
engine.
5. Observe the hour meter reading on diagnostic gauge/
hourmeter to determine if periodic maintenance is
necessary. Make appropriate entries in maintenance
logs. (See LUBRICATION AND MAINTENANCE
RECORDS Section.)
6. Perform required periodic maintenance on all other
equipment, as recommended by the equipment
manufacturers.
Operating Procedures

SHUTDOWNS AND ALARMS

1. Your unit is fitted with a system to protect it from
high water temperature or low oil pressure.
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: 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 shutdown system is
activated:
a. Check the temperature gauge. If the temperature is
above 205°F (97°C), shut off the engine immediately.
b. Use the Trouble Shooting Guide on pages 22- 24
to isolate the cause of the overheat.
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 180°F (83°C).
. Watch the temperature gauge regularly and turn
d
off the unit if the temperature rises above 200°F
(94°C). Repeat the troubleshooting process.
3. If the shutdown is activated and the temperature
gauge shows temperature within normal temperature
range:
a. Check the engine crankcase oil level.
b. 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 after a few seconds of operation.
c. If the oil level was normal, DO NOT restart the
engine. Call your Northern Lights or Lugger
dealer for assistance.
