Engine Operating Panel - MULTIQUIP Power WHISPERWATT DCA150SSI Operation And Parts Manual

The definitions below describe the controls and functions
of the Engine Operating Panel (Figure 5).
panel light
1. — 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.

preheat lamp
3. — 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.
4. Warning lamp — This lamp will illuminate whe a
critical engine fault has occured.
5. Engine Speed Switch
speed of the engine (low/high).
6. oil pressure gauge
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.
Water Temperature Gauge
7.
this gauge be should read between 167°~203°F (75°
~95°c
Charging Ammeter Gauge

being supplied by the engine's alternator which
provides current for generator's control circuits and
battery charging system.
Fuel gauge
9. — Indicates amount of diesel fuel
available.
Tachometer
10. — 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. auto Start/Stop engine Controller (eCu)
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.

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
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
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.

and duration are programmable. It is pre-set at 3
cycles with a 10 second duration. This is considered
a major fault.
