Logik f.INHIBIT
Signal of 12-PULSE_LOGIC-function block
This signal is generated by the 12 pulse switch-off logic. In case this signal is used at the
12 pulse data exchange the converters will try to switch off each other in the event of an
error.
Based on the connection diagram this interconnection should be done:
- in case a 12 pulse system without redundancy is in use (see INHIBIT_LOGIC (3607)):
- connect this output to input START_INHIBIT (908) at both converters, Master and
Follower
- in case a 12 pulse system with redundancy is in use (see BC_LOGIC (3616)):
- don´t use this signal at both of the converters and keep START_INHIBIT (908) to
default or application dependent
