DKG-155
MANUAL START UNIT
INSTALLATION AND OPERATING INSTRUCTIONS
The model DKG-155 is a microprocessor controlled
unit used to start and stop the genset manually
using the key switch on the front panel.
In the
OFF
position, the DC supply is removed from
the module, thus zero power consumption is
achieved.
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 also an optional variant with magnetic
pickup input. The teeth count is calibrated using a
potentiometer situated at the top of the unit.
The unit powers up when the
RUN
position on the
front panel is selected. This will also energize the
fuel solenoid relay. The engine is started using the
next spring-loaded position marked
START
. Once
the engine has started, the switch should be
released.
The alarm checking is only enabled after the
protection hold-off timer
is expired. This timer
resets to 45 seconds if the unit is powered up, it
resets to 10 seconds when 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,
-Spare alarm.
If a fault condition occurs, the
FUEL
solenoid will
be deenergized, the
ALARM
relay output will be
energized and the led associated with this fault
condition will turn on. To reset the fault condition,
turn the switch to the
OFF
position for a few
seconds.
The
Charge Fail
input 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,
select the
OFF
position on the switch.
