DKG-225, is a low cost AMF controller for 12V-DC
gensets, featuring an internal battery charger. Internal
fuel and crank relays are rated at 40Amps@12V-DC
and do not require external relays.
Thus a typical transfer panel will simply consist on
one DKG-225 and two contactors, reducing material
cost, panel size and production time.
The unit supports also current transformer
connections allowing detailed power measurements
from both mains and genset sides. The standard unit
supports 1A and 5A secondary CTs. A special version
supports low cost and small 0.1A secondary CTs
allowing more compact panel design.
The 1Amp @12V-DC rated battery charger is
sufficient for the float charging of the engine start
battery.
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 is no serviceable parts
inside.
Fuses of fast type with a maximum rating of 6A
must be connected to phase voltage inputs in close
proximity of the unit.
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. Values
exceeding limits may shorten device life, destroy its
precision or damage it.
Do not try to clean the device with solvent or the
like. Only clean with a dump cloth.
Do not allow water to come in the unit.
Verify correct terminal connections before applying
power.
Only for front panel mounting.
Before installation:
Read the user manual carefully, determine the
correct connection diagram.
Remove all connectors and mounting brackets from
the unit, then pass the unit through the mounting
opening.
Put mounting brackets and tighten. Do not tighten
too much, this can brake the enclosure.
Make electrical connections with plugs removed
from sockets, then place plugs to their sockets.
Make sure that the ambient temperature does not
exceed the maximum operating temperature limit.
During Installation:
Cables should be compatible with the operating
temperature range. Use adequate cable section, at
least 0.75mm
2
(AWG18).
Below conditions may damage the device:
Incorrect connections.
Incorrect battery voltage.
Reverse battery voltage
Voltage at terminals beyond specified range.
Voltage applied to digital inputs over specified
range.
Current at terminals beyond specified range.
Overload or short circuit at relay outputs.
Excessive vibration, installation on vibrating parts.
Below conditions may cause abnormal operation:
Battery voltage below minimum acceptable level.
Frequency out of specified limits
Missing grounding.
Make electrical connections with
plugs removed from sockets,
otherwise the unit may get
damaged.
Engine body must be grounded for
the correct operation of the unit.
Otherwise faulty voltage and
frequency measurements may
occur.
Do not install the unit close to
high electromagnetic noise
emitting devices like contactors,
high current busbars, switchmode
power supplies and the like.
