352),VDIH
If "override" mode is activated the operator can safely operate the associated plant area with
the enabling buttons. The HMI device is considered to be permanently logged on in the
effective range, without analyzing the transponder signals.
Deactivation of "override" mode
The operator deactivates "override" mode in the following manner:
1.
The operator activates the override switch.
"Override" mode is deactivated by the safety program.
2.
The operator logs off from the effective range.
Subsequent logon at this effective range is only possible if the operator has terminated
"override" mode with the override switch.
3.
The operator leaves the protected area.
If the operator leaves the protected area without deactivating "override" mode, "override"
mode is deactivated by the safety program.
