The definitions below describe the controls and functions
of the Engine Operating Panel (Figure 5).
1.
panel light — Normally used in dark areas or at night
time. When activated, panel lights will illuminate. When
the generator is not in use be sure to turn the panel light
switch to the OFF position.
2. panel light Switch — When activated will turn on control
panel light.
3. oil pressure gauge — During normal operation this
gauge should read between 42 ~71 psi. (290~490 kPa).
When starting the generator the oil pressure may read a
little higher, but after the engine warms up the oil pressure
should return to the correct pressure range.
4. Water Temperature gauge — During normal operation this
gauge be should read between 167°~203°F (75° ~95°C
5. Charging ammeter gauge — Indicates the current
being supplied by the engine’s alternator which provides
current for generator’s control circuits and battery
charging system.
6. Fuel gauge — Indicates amount of diesel fuel available.
7. Tachometer — Indicates engine speed in RPM’s for 60
Hz operation. This meter should indicate 1800 RPM’s
when the rated load is applied. In addition a built in hour
meter will record the number of operational hours that
the generator has been in use.
8. preheat lamp — As the engine cranks, this lamp will
illuminate to indicate automatic preheating of the engine
glow plugs. When the lamp turns off, this indicates that
the preheat cycle is complte and the engine will start
automatically.
9. Warning lamp — This lamp will illuminate when a critical
engine fault has occured.
10. Fuel leak Detected alarm lamp — This lamp will
illuminate when fuel level is low (25.5 gal/98 liters)
11. engine Speed Switch — This switch controls the speed
of the engine (low/high).
12. auto STarT/STop engine Controller (eCU) — This
controller has a vertical row of status LED's (inset),
that when lit, indicate that an
engine malfunction (fault) has
been detected. When a fault
has been detected the engine
controller will evaluate the fault
and all major faults will shutdown
the generator. During cranking
cycle, the ECU will attempt to
crank the engine for 10 seconds
before disengaging.
If the engine does not engage (start) by the third
attempt, the engine will be shutdown by the engine
controller’s Over Crank Protection mode. If the engine
engages at a speed (RPM's) that is not safe, the
controller will shutdown the engine by initializing the
Over Speed Protection mode.
Also the engine controller will shut down the engine in
the event of low oil pressure, high coolant temperature,
low coolant level, and loss of magnetic pickup.
These conditions can be observed by monitoring the
LED status indicators on the front of the controller
module.
A. mpeC Control Switch — This switch controls the
running of the unit. If this switch is set to the OFF/
RESET position, the unit will not run. When this switch
is set to the manual position, the generator will start
immediately.
If the generator is to be connected to a building’s
AC power source via an automatic transfer switch
(isolation), place the switch in the AUTO position. In this
position, should an outage occur, the automatic transfer
switch (ATS) will start the generator automatically
via the generator’s auto-start contacts connected to
the ATS’s start contacts. Please refer to your ATS
installation manual for further instructions for the
correct installation of the auto-start contacts of the
generator to the ATS.
B. low oil pressure — Indicates the engine pressure
has fallen below 15 psi (103 kPa). The oil pressure
is detected using variable resistive values from the
oil pressure sending unit. This is considered a major
fault.
C. high Coolant Temperature — Indicates the engine
temperature has exceeded 230°F (110°C). The engine
temperature is detected using variable resistive values
from the temperature sending unit. This is considered
a major fault.
D. overcrank Shutdown — Indicates the unit has
attempted to start a pre- programmed number of
times, and has failed to start. The number of cycles
and duration are programmable. It is pre-set at 3
cycles with a 10 second duration. This is considered
a major fault.
E. overspeed Shutdown — Indicates the engine is
running at an unsafe speed. This is considered a
major fault.
F. engine running — Indicates that engine is running
at a safe operating speed.
