CHAPTER 6
6.3 NORTHERN LIGHTS 240V 9KW GENERATOR
See Northern Lights Generator Operating Manual. for more information
.
Break-In Period
Change engine oil and filter at 50 hours and again at 100 hours. Oil consumption
is greater until piston rings are seated. Maintain at least a 75% load on the generator for the first 100
hours, varying the load to help seat the rings.
Generator Racor Fuel Pre-Filter
is located to port of the Genset and
forward against the bulkhead in the engine room of the triple engine 50z
and on the aft bulkhad on the twin. The
Groco Rawe Water Strainer
should be close by
Pre-Start Checks
Refer to diagrams of genset on next page.
(1) Check coolant is 1” below filler cap
(2) Check oil at dipstick
(3) Open fuel line lever over port fuel tank.
(4) Close the raw water seacock, check & clean sea strainer & reopen
seacock
(5) Turn ON the GENERATOR BATTERY SWITCH over the 12v DC
Panel. Keep this ON whilte running or the battery charging regulator could be damaged.
(6) Be sure Breaker on 120V AC Panel that reads Generator/Shorepower 1 is ON.
(7) Keep OFF the GENERATOR switch on the 240V AC Panel which activates the Air Conditioning,
Hot Water Heater and Gyro.You don’t want to start the generator with any load.
(8) Turn OFF the Inverter toggle switch on Victron Phoenix Panel
(9)
PREHEAT
: On the Control Panel, DEPRESS PREHEAT ON and hold for 10 Seconds
(10)
START:
Then, depress START switch while continuing to depress PREHEAT switch. Keep
pressing in for a few seconds to be sure the Generator is running.
(11) RELEASE both switches. Do not crank for more than 20 seconds at a time. Allow the generator
to run for about 15 seconds
(12) Tun ON GENERATOR Selection switch on the
240V AC Panel to activate all circuits and be sure that
the two HOUSE and ENGINE START BATTERY
switches are ON. Check to see that digital meters on
Panels are reading volts
NOTE: if the generator starts, but no AC voltage is
seen, check first that the selector switches (sliding
interlocks) are ON. If so, there is a
possibility the generator was overloaded and the AC
breaker on the generator Control Box has tripped due
to a momentary overload. Open the generator cover
and reset (pull up) the AC Output Circuit Breaker
TO STOP:
Turn OFF GENERATOR Selector switch on the 240v AC Panel. Allow the
generator to run for a 3-5 minute cool-down period. Depress STOP momentarily on the
lower part of the rocker switch. Turn OFF the GENERATOR BATTERY SWITCH over
the 12v DC Panel.
POWER MANAGEMENT
A following page shows the amperage draw of various
electrical equipment on the boat as an aid to managing those loads on the generator..
The 9KW Generator is not designed to power all equipment at one time.
