DCA-600SSV — OPERATION AND PARTS MANUAL — REV. #0 (07/13/09) — PAGE 23
DCA-600SSV — GENERATOR CONTROL PANEL
14. Auto On/Off Engine Controller (MPEC) – This
controller has a vertical row of status LED's (inset),
that when lit, indicates 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
MPEC will attempt to crank
the engine for 10 seconds
before disengaging.
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 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 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 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. The oil pressure is detected
using variable resistive values from the oil pressure
sending unit. This is considered a
major
fault and will
shut down the generator.
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 and will shut down the generator.
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. Typical programmable
start settings is 3 cycles with a 10 second duration.
This is considered a
major
fault and will shut down
the generator.
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.
10. Circuit Breaker OFF Lamp – When the circuit
breaker ON switch is placed in the OFF position this
lamp will be turned OFF.
11. Circuit Breaker ON Lamp – When the circuit breaker
ON switch is placed in the ON position this lamp will
be turned ON.
12. Circuit Breaker OFF Switch – Press this switch to
place the 1600 amp circuit breaker in the open (OFF)
position.
13. Circuit Breaker ON Switch – Press this switch to
place the 1600 amp circuit breaker in the closed (ON)
position.
