Description
1
GENERATOR CONTACTOR
Relay output, 16A-AC This output provides energy to the generator
contactor. If the generator phases do not have
acceptable voltage or frequency values, the
generator contactor will be de-energized. In
order to provide extra security, the normally
closed contact of the mains contactor should
be serially connected to this output.
2
GEN-L1
Generator phase
inputs, 0-300V-AC
Connect the generator phases to these inputs.
The generator phase voltages upper and
lower limits are programmable.
3
GEN-L2
4
GEN-L3
5
GENERATOR NEUTRAL
Input, 0-300V-AC
Neutral terminal for the generator phases.
6
MAINS NEUTRAL
Input, 0-300V-AC
Neutral terminal for the mains phases.
7
MAINS-L3
Mains phase inputs,
0-300V-AC
Connect the mains phases to these inputs.
The mains voltages upper and lower limits are
programmable.
8
MAINS-L2
9
MAINS-L1
10
MAINS CONTACTOR
Relay output, 16A-AC
This output provides energy to the mains
contactor. If the mains phases do not have
acceptable voltages, the mains contactor will
be de-energized. In order to provide extra
security, the normally closed contact of the
generator
contactor
should
be
serially
connected to this output.
11
GROUND
O VDC
Power supply negative connection.
12
BATTERY POSITIVE
+12 or 24VDC

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.
