DCA-100SSJU — PARTS AND OPERATION MANUAL (STD)— REV. #2 (05/03/01) — PAGE 33
The definitions below describe the controls and functions of
the DCA-100SSJU "
Engine Operating Panel " (Figure
10).
1.
Panel light - Normally used in dark places or at night.
When activated, panel will luminate. When the generator
is not in use, 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 – Normal operation should be about
25 psi. When starting the generator the oil pressure
may read a bit higher, but after the engine warms up
the oil pressure should return to normal.

9.
Pre-Heat Button – Press hold this button
(Figure 11) until the preheat lamp is lit
(ON).
10. MPEC – Microprocessor
Engine Control Module –
(MPEC) has a vertical row of
status LED's (Figure 11), that
when lit, indicate that an engine
malfunction (fault), has been
detected. When a fault has
4.
Water Temperature Gauge – During normal operation
this gauge be should read between 165
o
F to 215
o
F.
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.
Engine speed Handle- This handle will change the
speed of the engine from high to low.
been detected the MPEC will evaluate the fault and all
major faults will shutdown the generator. During
cranking cycle , The MPEC 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 MPEC's " Over Crank
Protection" mode. If the engine engages at a speed
(RPM's) that is not safe, the MPEC will shutdown the
engine by initializing the "Over Speed Protection" mode.
Also the MPEC will shutdown the generator 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 MPEC module.
A.
Off/Manual/Auto Switch – This switch controls the
running of the generator. If this switch is left in the "OFF"
position, the generator 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 a transfer switch (isolation), place the
switch in the
auto position. In this position the generator
will monitor the AC line output from the building's power
source.
B.
Low Oil Pressure – Indicates the engine pressure
has fallen below 15 psi. 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 215
°
F. 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 preset 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.
