9.1.12 MCB 112 PTC Termistor Card

The following two examples show the possibilities, when using the VLT PTC Thermistor Card MCB 112.
Connection of MCB 112
Terminals X44/ 1 and X44/ 2 (T1 and T2) are used to connect the PTCs from the motor with the option card. X44/ 12 is connected with Safe Stop terminal
37 of the FC 302.
Terminal X44/ 10 is connected to a digital input of the FC 302. This digital input can be terminal 33, but this is only an example - any other digital input
could be used instead. The use of this signal allows the drive to determine, which source has activated the Safe Stop, as other components can be
connected to the Safe Stop terminal 37 of the FC 302 at the same time.
NB!
Terminal X44/10 must be connected.
