Table 2.2 Unit wiring description
Pin Function
1 L1
2 L2
3 L3
Mains voltage inputs. Used to detect failure for controlling automatic transfer of load
to alternator. Pins 2 and 3 not used on single phase applications.
4 Mains voltage neutral
5 L1
6 L2
7 L3
Alternator voltage inputs. Unit can be programmed to use frequency of alternator
output to detect when engine has started. Pins 6 and 7 not used on single phase
applications.
8 Alternator voltage neutral
9 Not connected
10 Fuel level sender
11 Coolant temperature sender
12 Low oil pressure sender
13 Magnetic input +ve. An AC signal from the magnetic pick-up +ve for speed sensing.
14 Magnetic input –ve. An AC signal from the magnetic pick-up -ve for speed sensing.
15 Input from charge generator. Can be used to detect when engine has started.
16
Configurable input-6. This is a negative switched configurable input, see Digital
Configurable Input-6 Page Section for options available. It is possible to configure input to
be a normally closed signal or a normally open signal.
17
High Temperature or Configurable input-5. This is a negative switched. If Configurable
input-5 is not selected as High Temperature, It is possible to configure input to be a
normally closed signal or a normally open signal. See Digital Configurable Input-5 Page
Section for options available.
18
Low Oil Pressure or Configurable input-4. Normally closed contact. Switch to 0V. If
Configurable input-4 is not selected as Low Oil Pressure, It is possible to configure input to
be a normally closed signal or a normally open signal. See Digital Configurable Input-4 Page
Section for options available.
19
Configurable input-3. This is a negative switched configurable input, see Digital
Configurable Input-3 Page Section for options available. It is possible to configure input to
be a normally closed signal or a normally open signal.
20
Configurable input-2. This is a negative switched configurable input, see Digital
Configurable Input-2 Page Section for options available. It is possible to configure input to
be a normally closed signal or a normally open signal.
21
Configurable input-1. This is a negative switched configurable input, see Digital
Configurable Input-1 Page Section for options available. It is possible to configure input to
be a normally closed signal or a normally open signal.
22
Input from emergency stop switch. Normally closed contact. Switch to 0V. when the switch
is opened, the engine is stopped.
