OPEN and CLOSE outputs
The
EXE_OP
output is activated when the open command is given (
AU_OPEN
, via
communication or from LHMI) and
OPEN_ENAD
signal is TRUE. In addition, the
protection trip commands can be routed through the CBXCBR function by using
the
TRIP

EXE_OP
output is activated
immediately and bypassing all enabling or blocking conditions.
The
EXE_CL
output is activated when the close command is given (
AU_CLOSE
, via
communication or from LHMI) and
