Figure 307:

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.

Figure 308:

Condition for enabling the open request (OP_REQ) for CBXCBR

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.
