X44/ 1 and X44/ 2 are the thermistor inputs, X44/ 12 will
enable safe stop of the FC 102 (T-37) if the thermistor
values make it necessary and X44/ 10 will inform the FC
102 that a request for safe stop came from the MCB 112 in
order to ensure suitable alarm handling. One of the digital
Inputs of the FC 102 (or a DI of a mounted option) must
be set to PTC Card 1 [80] in order to use the information
from X44/ 10.
