DKG-154
REMOTE START UNIT
INSTALLATION AND OPERATING INSTRUCTIONS
The DATAKOM model DKG-154 is a low cost,
microprocessor controlled unit designed to start
and stop the genset automatically on request of an
external Remote Start signal.
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 the
auxiliary relay 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 :
50 Hz nominal, AUX is Preheat output
B & C :
60 Hz nominal, AUX is Preheat output
C & D :
60 Hz nominal, AUX is Stop output
D & A :
50 Hz nominal, AUX is Stop output
In the
OFF
position, the DC supply is removed from
the module, thus remote start operation is disabled
and zero power consumption is achieved.
The unit powers up when the
AUTO
position on the
front panel is selected. It will start the engine when
its Remote Start input is pulled to battery negative
and will act like below:
If
‘Preheat’
option is selected, it energizes the
AUXILIARY
output for
Preheat Delay
, then
releases it.
Then it energizes the
FUEL
output for
Wait Before
Start
delay, then energizes the
START
output for
Start Duration
. If the engine fires, the start output
is immediately released. The protections will be
enabled only after the
Protection Hold-off Timer
has expired.
If the engine does not fire, start and fuel outputs are
deenergized, if
‘Preheat’
option is selected, the
AUXILIARY
output will be energized and the unit
will wait for
Wait Between Starts
period before a
new crank cycle is initiated. The engine is cranked
up to 3 times.
If the Remote Start signal disappears while the
engine is running, the engine will continue to run for
Cooldown Duration
. Then the fuel output is
deenergized, if the
‘Activate to Stop’
option is
selected, the
AUXILIARY
output will be energized
for
Stop Timer
, and the unit will be ready for a new
Remote Start.
The
PREHEAT/STOP (
)
led will continuously
indicate the
AUXILIARY
output status.
The occurrence of below fault conditions will cause
the engine to be stopped immediately:
-Overspeed,
-Underspeed,
-High engine temperature,
-Low oil pressure,
If a fault condition occurs, the
FUEL
solenoid will
be deenergized. I
f the ‘
Energize to Stop
’ option is
selected, the
AUXILIARY
output will be energized
during
Stop Timer
and the led associated with this
fault condition will turn on.
Only the first occurring fault will be indicated. 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.
