Datakom DKG-155 Installation And Operating Instructions

INSTALLATION AND OPERATING INSTRUCTIONS
DESCRIPTION
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.
OPERATION
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.

MANUAL START UNIT
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.
