DCA-150SSJU — PARTS AND OPERATION MANUAL — REV. #3 (09/07/01) — PAGE 31
The definitions below describe the controls and functions of
the DCA-150SSJU "
Engine Operating Panel " with Serial
Number greater than7600090 (Figure 9).
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 panel
light.
3. Oil Pressure Gauge – During normal operation this
gauge be should read 42 to 71 psi. When starting the
generator the oil pressure may read slightly higher, but
after the engine warms up the oil pressure should return
within that range.
4. Water Temperature Gauge – During normal operation
this gauge be should read 165
o -203 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. Auto Start Controller – This controller will indicated
with LEDs that an engine fault has been detected. When
a fault has been detected the controller will evaluate
the fault will shutdown the generator if it may be
damaging to the engine.
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
DCA-150SSJU — ENGINE OPERATING PANEL (With Engine Controller)
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 be started 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 that 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.
9. Throttle Handle - This handle controls the speed of
the engine (low or high).
10. Pre-Heat Button – This is to pre-heat the engine under
extreme cold conditions.
