Écran C F H - Carré C (SNCF)

Signal-ID: 240 (hex: 0xF0)

Using this signal configuration, the following signals can for example be operated:

Châssis-Écran C
Châssis-Écran F
Châssis-Écran H

Using this signal configuration, the small Châssis-Écran A can also be operated with only two or three lamps. For easier operation, however, we recommend that you use the signal configuration "Écran A" with Signal-ID 242 (hex: 0xF2).

This signal configuration is designed to switch two violet lamps (Carré CV). If you wish to connect signals with a violet lamp (Carré violet C), then use the signal configuration "Écran C F H - Carré violet Cv" with Signal-ID 241 (hex: 0xF1).

With the usual DCC "Basic Accessory Command", only 4*4=16 signal aspects can be switched, see the columns "Trigger" and "Mode".Theoretically, however, an SNCF signal can when fully developed present more than 16 signal aspects. For this reason, restrictions must be made for the signal aspects "RR+(A)" and "(RR)+(A)", which are rare anyway.

If you wish to use the full scope of functions and really want to switch all possible signal aspects, then you can do this using a DCC control centre which commands the "DCC Extended Accessory Command". See also the column DCCext:

The signal aspects C, S, M, A and VL are switched with the values 0, 1, 2, 4 and 16.
Then add 32 to obtain the flashing variants (S), (M), (A) and (VL).
The signal aspect "Ralentissement 30 R" or "Ralentissement 60 (R)" is switched with the value 3 or 6.
Then add 64 to obtain the repeat variant "Rappel de ralentissement 30 RR" or "Rappel de ralentissement 60 (RR)".
To obtain combinations of A and R or RR, add the respective values. Example: "(RR)+(A)" = (6+64)+(4+32) = 106.
