The AGM60… switch unit connected to the LMV36... serves for changeover of valve
control or for feedback signals from the 2 types of fuel. The signals are monitored by the
LMV36... basic unit (same as with the single-fuel variant) which, in the event of fault,
also triggers shutdown.

2.4.1 Electrical connections of fuel actuators
When using only 1 fuel actuator, it must be connected directly to the LMV36... In that
case, a connecting cable (AGV61.100) is not required.
When using 2 fuel actuators for each type, they must be connected to the AGM60...
Fuel selection choices:
- Gas / oil
- Gas / gas
- Oil / oil
When wiring the components, we recommend to make the following fuel assignments as
standard:
Fuel 0 = gas
Fuel 1 = oil
This can be set via parameter 201 / 301 (refer to chapter Selection of operating mode).
Following switching’s of inputs and outputs are made via AGM60...:
- Fuel at the LMV36...
- Fuel valve
- Pressure switch or POC
- Actuator (SQM3... or SQN1...)
