The definitions below describe the controls and functions
of the Engine Control Panel (Figure 5).
1.
panel light Switch
— When activated will turn on
control panel light
2.
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.
3.
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 complete and the
engine will start automatically.
4.
Warning lamp
— This lamp will illuminate whe a
critical engine fault has occured.
5.
Coolant alarm lamp
— This lamp will illuminate when
the coolant level falls below a safe operating level and
the engine will stop.
6.
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.
7.
Water Temperature gauge
— During normal operation this
gauge be should read between 167°~203°F (75°~95°C).
8.
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.
9.
Fuel gauge
— Indicates amount of diesel fuel
available.
10.
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.
11.
engine Speed Switch
— This switch controls the
speed of the engine (low/high).
12.
emergency Stop Button
— Push this button inward to
stop the engine in the event of an emergency.
Do noT
use this button as a means of stopping the engine.
13.
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.
