Electric locomotive selectors

Registered by Cédric GNIEWEK

An electric locomotive may need several selectors. The most common are the following:
- Pantograph selector: a locomotive may raise the pantograph at the front or at the rear or both.
- Voltage selector: a locomotive needs to configure its systems in order to accept the right voltage from the overhead wire.
- Power limiter selector: on some lines, the power available on the overhead wire is limited. The locomotive must be able to limit its power consumption in order to not decrease too much the voltage.

All of these selectors must be scriptable in order to take the particularities of a locomotive into account.

The selectors will give information to the power supply classes in order to trigger the right pantograph and to limit the power of the locomotives.
The power supply classes will also receive information from the TCS in order, for example, to check that the right voltage is selected.

In order to give an idea of what will be available, here's the example of what's available on a TGV Atlantic:

The pantograph selector has 3 positions: normal, rescue, local.
The pantographs that are raised depends on the voltage selected on the voltage selector:
- 1500 V : normal => all pantographs are raised, rescue => all pantographs are raised, local => only the pantograph at the front of the train is raised
- 25000 V : normal => the rear pantograph of each EMU is raised, rescue => the front pantograph of each EMU is raised, local => only the pantograph at the front of the train is raised

The voltage selector has 3 positions:
- 1500 V
- 25000 V conventional line
- 25000 V high speed line

The power limiter has 3 positions: I, II and III.
Depending on the position of this selector, the position of the voltage selector and the number of EMU in the train, the locomotives are power limited to different values.
