Figure 516: Condition for enabling the close request (CL_REQ) for CBXCBR
When the open command is given from communication, via LHMI or activating the
AU_OPEN input, it is processed only if OPEN_ENAD is TRUE. OP_REQ output is also
available.

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 input. When the TRIP input is TRUE, the 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 CLOSE_ENAD signal is TRUE. When the TRIP
input is “TRUE”, CB closing is not allowed.
