3.5 Plug-In Check
Output 2c12 (KA) outputs a 12 V signal which is looped via all the I/O modules of the
controller. The loop is closed at 2c10 (KE) of the UKA. An interrupted loop is evaluated
(marker 20). If a signal check loop is not to be connected, 2c10 is to be jumpered with
2c12.
3.6 PEAB Monitoring
The perfect condition of the PEAB is monitored and signalled by saving and rewriting
PEAB signals. The following figure shows the hardware prerequisites for a system
