Error lock
If the input is inactive = OFF when the safe outputs are switched off or active = ON when the
safe outputs are switched on, the system switches to the error state and locks.
Limited error lock
If the input is inactive = OFF when the safe outputs are switched off, the system switches to
the error state and locks. If the input remains active after the safe outputs are switched
active = ON, e.g. when the contactor no longer engages due to a blown fuse, the contactor
monitor switches the safe outputs of the OSSD back off.
Configuration log
Note
With dynamic contactor monitoring with error lock, series connection of the contactor controller
with operational switches is not possible.
Notice
The combination of the dynamic contactor monitoring with limited error lock together with au-
tomatic start is not permitted, as in this combination it is possible for the safe outputs of the
AS-Interface safety monitor to be continuously switched on and off.
