Term Function Technical data Description
11 GROUND O VDC Power supply negative connection.
12 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.
13 SPARE SENDER INPUT Input, 0-5000 ohms No connection to this terminal.
14 OIL PRESSURE SENDER Input, 0-5000 ohms Analogue oil pressure sender connection. Do
not connect the sender to other devices. The
input has programmable characteristics and
connects to any kind of sender.
15 COOLANT TEMP. SENDER
Input, 0-5000 ohms Analogue high temperature sender
connection. Do not connect the sender to
other devices. The input has programmable
characteristics and connects to any kind of
sender.
16 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.
17 RELAY-2 (HORN RELAY) Output 10A/28VDC This relay has programmable function,
selectable from a list.
18 RELAY-1 (STOP RELAY) Output 10A/28VDC This relay has programmable function,
selectable from a list.
19 START RELAY Output 10A/28VDC This relay controls the engine cranking.
20 FUEL RELAY Output 10A/28VDC This relay is used for fuel solenoid control. It is
internally connected to terminal 16 for
supplying the charge alternator’s excitation
current.
21 EMERGENCY STOP Digital inputs These inputs have programmable
characteristics selected via the program
menu. Each input may be driven by a
‘
normally closed ’ or ‘ normally open ’ contact,
switching either or battery- . The
effect of the switch is also selectable from a
list. See
PROGRAMMING section for more
details.

25 COOLANT LEVEL
26 HIGH TEMP
27 LOW OIL PRESSURE
28 RECTIFIER FAIL
29 Current transformer
inputs, 5A-AC
Connect the generator current transformer
terminals to these inputs. Do not connect the
same current transformer to other instruments
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).
