Procedure
To open the control cabinet door, set the motor
starter protector to O (OFF). This will release the
extension shaft from the rotary operating
mechanism so that you can open the door.
If you need to open the control cabinet door
during operation, press the knob next to the
rotary knob to "override" the interlock (Step 1).
To close the door during operation, press this
knob again so that the extension shaft can re-
engage.
