GROUND
O VDC
Power supply negative connection.
31
CHARGE
Input and output
Connect the charge alternator’s D+ terminal
to this terminal. This terminal will supply the
excitation current and measure the voltage of
the charge alternator.
32
RELAY-6 (FUEL RELAY)
Output 10A/28VDC
This relay is normally used for fuel solenoid
control. It is internally connected to terminal
31
for supplying the charge alternator’s excitation
current.
33
RELAY-2 (CRANK RELAY)
Output 10A/28VDC
This relay has programmable function,
selectable from a list. However it is generally
used as engine crank output.
34
BATTERY POSITIVE
+12 or 24VDC
The positive terminal of the DC Supply shall
be connected to this terminal. The unit
operates on both 12V and 24V battery
systems, depending on the voltage selection
jumper. Do not operate a 12V-DC unit with a
24V-DC system. This may cause the
destruction of the unit. Always disconnect
the voltage selector jumper of a stocked unit.
35
RELAY-7 (STOP RELAY)
Output 10A/28VDC
36
RELAY-1 (PREHEAT)
Output 10A/28VDC
37
RELAY-3 (ALARM RELAY)
Output 10A/28VDC
These relays have programmable functions,
selectable from a list.

Current transformer
inputs, 5A-AC
Connect the mains current transformer
terminals to these inputs. Do not connect the
same current transformer to other units than
DKG-705 otherwise a unit fault will occur.
Connect each terminal of the transformer to
the unit’s related terminal. Do not use
common terminals. Do not use grounding.
Correct polarity of connection is vital. If the
measured power is negative, then change the
polarity of each 3 current transformers. The
rating of the transformers should be the same
for each of the 3 phases. The secondary
winding rating shall be 5 Amperes. (For ex.
200/5 Amps).

MAGNETIC PICKUP
Inputs, 0.5-70V
0-20KHz
Connect the magnetic pickup signal to these
inputs.

AVR CONTROL
Output,
isolated resistor,
300-100,000 ohms.
AVR voltage control outputs. Connect to the
external adjust potentiometer terminals of the
AVR. The polarity is not important.
48
GOVERNOR CONTROL
Output, 0-10VDC
Connect this output to the terminal
‘J’
or ‘
EXT
’
of the speed governor.
