Opening and closing operations
The opening and closing operations are available via communication, binary inputs or
LHMI commands. As a prerequisite for control commands, there are enabling and
blocking functionalities for both opening and closing commands (CLOSE_ENAD and
OPEN_ENAD signals). If the control command is executed against the blocking or if the
enabling of the corresponding command is not valid, 52 generates an error message.
When close command is given from communication, via LHMI or activating the
AU_CLOSE input, it is carried out (the EXE_CL output) only if CLOSE_ENAD is TRUE.
If the 25 function is used in “Command” mode, the CL_REQ output can be used in 52.
Initially, the SYNC_OK input is FALSE. When the close command given, it activates the
CL_REQ output, which should be routed to 25. The close command is then processed only
after SYNC_OK is received from 25.
When using 25 in the “Command” mode, the 52 setting Operation timeout
should be set longer than 25 setting Maximum Syn time.

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.
