9.7 PTC Thermistor Card MCB 112
The MCB 112 option makes it possible to monitor the
temperature of an electrical motor through a galvanically-
isolated PTC thermistor input. It is a B-option for FC 302
with Safe Torque Off (STO).
For information on mounting and installing the option, see
the instructions that accompany it. For different
application possibilities, see .
X44/1 and X44/2 are the thermistor inputs. X44/12 enables
safe torque off of the FC 302 (T-37) if the thermistor values
make it necessary, and X44/10 informs the FC 302 that a
request for safe torque off has come from the MCB 112 to
ensure suitable alarm handling. One of the digital inputs of
the FC 302 (or a DI of a mounted option) must be set to
PTC Card 1 [80] in order to use the information from
X44/10. 5-19 Terminal 37 Safe Stop must be configured to
the desired safe torque off functionality. Default is safe
torque off alarm.
