INSTALLATION AND OPERATING INSTRUCTIONS

DESCRIPTION

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.

OPERATION

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 (

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. If 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.
