DKG-175 AUTOMATIC
TRANSFER SWITCH
(WITHOUT DC SUPPLY)
Datakom DKG-175 is a DIN Rail mounted ATS
controller not requiring DC supply. Thanks to this
feature, it is not required to carry the DC supply from
the battery to the transfer panels, providing ease of
installation.
The unit monitors 3-phase mains voltages, sends
remote start command to the generating set and
performs changeover of both generator and mains
contactors.
The front panel leds provide information about mains
and generator power availability as well as contactor
positions. Moreover, mains phase voltages and
frequency can be seen on front panel.
Mains voltage and frequency high and low limits,
mains waiting timer, mains fail timer, generator start
delay, cooldown timer and mains contactor timer are
front panel programmable. Generator contactor timer
is adjustable between 1 and 40 seconds through front
panel knob.
DIN Rail mounted
No DC supply required
Mains phase order check

Programmable mains frequency and voltage high
and low limits
Programmable delay timers
10A/250VAC MCB and GCB outputs
10A/28VDC remote start output

Electrical equipment should be installed only by qualified specialist. No responsibility is
assured by the manufacturer or any of its subsidiaries for any consequences resulting from
the non-compliance to these instructions.
Check the unit for cracks and damages due to transportation. Do not install damaged
equipment.
Do not open the unit. There are no serviceable parts inside.
Fuses must be connected to the power supply and phase voltage inputs, in close proximity of
the unit.
Fuses must be of fast type with a maximum rating of 6A.
Disconnect all power before working on equipment.
When the unit is connected to the network do not touch terminals.
Any electrical parameter applied to the device must be in the range specified in the user
manual. Although the unit is designed with a wide safety margin, over-range parameters may
reduce lifetime, alter operational precision or even damage the unit.
Do not try to clean the device with solvent or the like. Only clean with a dump cloth.
Verify correct terminal connections before applying power.

Although the unit is protected against electromagnetic disturbance, excessive disturbance can affect the
operation, measurement precision and data communication quality.
ALWAYS remove plug connectors when inserting wires with a screwdriver.
Fuses must be connected to the power supply and phase voltage inputs, in close
proximity of the unit.
Fuses must be of fast type with a maximum rating of 6A.
Use cables of appropriate temperature range.
Use adequate cable section, at least 0.75mm2 (AWG18).
Follow national rules for electrical installation.
Do not install the unit close to high electromagnetic
noise emitting devices like contactors, high current
busbars, switch mode power supplies and the like.

If 3-phases of mains voltage and frequency are withing limits and phase order is correct:
-MC, RST leds turn on.
-MCB terminal is supplied with voltage R.
-REMOTE START relay will be energised. (Normally closed and normally open contacts will switch
position.)
If any phase voltage or frequency goes outside of the limits:
-ALARM led turns on, RST led turns off.
-After the expiration of mains fail timer MCB terminal is open, MC led turns off.
-REMOTE START relay de-energises after engine start delay timer. (Contacts switch back to normal
positions) Generator must run.
When genset voltage is over the limit:
-G led turns on.
-GC led turns on after generator contactor timer. GCB terminal is supplied with voltage G.
When mains voltages and frequency are inside the limits:
-RST led turns on.
-ALARM led turns off.
-After the expiration of mains waiting timer, GCB terminal is open.
-After the expiration of mains contactor timer, MC led turns on, MCB terminal is supplied with voltage R.
-After expiration of Cooldown timer (Cooldown timer starts counting when GCB terminal is open)
REMOTE START relay energises. (Normally closed and normally open contacts will switch position.)
Test mode will be active if button is held pressed for 2 seconds on operation mode. ALARM led
blinks, remote start relay will be deactive and generator is expected to start. Test mode will be disabled
at the end of test mode timer.Test mode will also be disabled by holding pressed the button for 2
seconds before expiration of test mode timer.
