Opening the door with significant force
Note
If the motor starter protector is set to ON and the door is opened with a force of
> 150 to 200 N, the extension shaft cap will break away from the rotary switch on the motor
starter protector to prevent irreparable damage to the motor starter protector. The motor
starter protector remains set to ON.
The extension shaft then needs to be re-attached to the motor starter protector and the door-
coupling rotary operating mechanism as described below:
