Overview
DORMA operators meet high safety standards and comply
with all required technical rules and requirements. Operator-
monitors internal as well as external safety circuits that are
managed / monitored by the operator.
While operator is in use, certain situations may develop that
cause error messages.
Operator attempts to identify the cause and respond accordingly.
The response depends on severity of error and may vary from
a simple notification to deactivating the operator's automa-
tic function. In this case, operator will switch to emergency
mode and act like a door closer. Users can then access door
manually.

well as operating situations that interrupt automatic function
of operator system.

movement was stopped by operator.

turned into an error message.
