You can override the door interlock by a deliberate action. In this way, you can also open the

Door interlock
The door interlock of the door mounted rotary operator locks the door as soon as the door
mounted rotary operator is turned to position ON.
The door interlock can be overridden by a deliberate action. This is done by pressing the
door interlocking pin on the left side of the masking plate with a sharp object (e.g. a narrow
screwdriver). This means that the door can be opened with the operator in position ON so
that maintenance can be carried out, for example.
