INSTALLATION AND OPERATING INSTRUCTIONS
DESCRIPTION
The model DKG-153 is a microprocessor controlled
unit used to start and stop the genset manually
using the key switch and pushbuttons on the front
panel.
When the engine is running, the unit monitors fault
conditions and shuts-down the engine automatically
in the occurrence of an alarm. The alarms are
identified by a group of LEDs displaying only the
first occurring one.
The unit has jumper selectable options for 50/60Hz
nominal frequency and the auxiliary output function.
The selection is made by the position of a single
jumper situated at the left side panel of the unit.
If the jumper is placed between:
A & B : 50Hz nominal, AUX is Preheat output
B & C : 60Hz nominal, AUX is Preheat output
C & D : 60Hz nominal, AUX is Stop output
D & A : 50Hz nominal, AUX is Stop output.
In the OFF position, the DC supply is removed from
the module, thus zero power consumption is
achieved.
OPERATION
The unit powers up when the RUN position on the
front
panel
is
selected.
PREHEAT/STOP (
) button may be depressed
as long as needed. This will activate the
AUXILIARY relay output and the related front panel
led marked (

MANUAL START UNIT
The engine is started using the pushbutton marked
CRANK (I). This will also energize the fuel solenoid
output. Once the engine is running, the switch
should be released. However the internal logic
inhibits cranking when the engine fires up.
The alarm checking is only enabled after the
protection hold-off timer is expired. This timer
resets to 12 seconds if:
-the unit is powered up,
-or CRANK (I) button is pressed,
-or PREHEAT/STOP (
-or the engine gets running.
The occurrence of below fault signals (which are
close on fault) will cause the engine to be stopped
immediately:
-Overspeed,
-Underspeed,
-High engine temperature,
-Low oil pressure,
-Auxiliary shutdown.
If a fault condition occurs, the FUEL solenoid will
be deenergized. If the auxiliary output is set to Stop
option, it will be energized during stop timeout and
the led associated with this condition will turn on.
To reset the fault condition, turn the switch to the
OFF position for a few seconds.
The Charge Fail condition is treated as a warning
only and do not cause the engine to stop. The input
monitors the D+ terminal of the charge alternator.
To shut-down the engine manually:
-if the AUX output is set to Stop option, press the
PREHEAT/STOP (
comes to rest. Then select the OFF position on the
switch.
-else select the OFF position on the switch.
