4.1.6.4 Oil valves, type SI (X8-02, X8-03, X7-01, X7-02, X6-03)

These outputs are used for connecting the oil valves in accordance with the selected
fuel train. ↑ Fuel trains, ↑ Sequence diagrams.
Parameter FuelTrainOil (LightOilLO / HeavyOilHO / LO w Gasp / HO w
Gasp)
(Light oil with gas pilot and heavy oil with gas pilot may only be used in connection with
Gp2)

4.1.6.5 Gas valves, type SI (X9-01)

These outputs are used for connecting the gas valves in accordance with the selected
fuel train. ↑ Fuel trains, ↑ Sequence diagrams.
Parameter FuelTrainGas (DirectIgniG / Pilot Gp1 / Pilot Gp2)

4.1.6.6 Operation indication gas / oil, type SI (X8-01)

This output shows the operating position of the LMV5.
The outputs are connected directly to valve output V1Oil or V1Gas. The operating
position outputs for oil and gas must not be directly connected, since a wrong contact
position of valve output 1 (unused fuel) would be detected, which would lead to lockout.
Note!
During the valve proving sequence Filling, gas valve (V1) is controlled, so that Gas is
displayed for a moment!
