Checking the polarity of the two-states magnets (for end slowdowns)
The polarity of the two-state magnets must be checked to ensure that the upper and
lower slowdowns will be correctly read by the controller.
RH stands for upper end slowdown
RB stands for lower end slowdown
This checking may be done visually thanks to both leds RH and RB on CB2 plug on 211SP board:
Or by enabling the VTA function (see chapter §1 Annex 3)
Or in the following menu of the controller :
+ …
+ …
CAR’S POSITION : EXPECTED STATES ON RH / RB :
Above « Highest slowdown ACTIVE »
RH
Between
RH & RB
Below « Lowest slowdown ACTIVE »
RB
Reverse the magnets vertically, if the states seen are wrong.
