1. There must be a run-on of 0.5 mm in the fully operated position before the plunger reaches the stop

(for safety reasons);

2. Auxiliary limit switch 11.4 (Q8S2) for earthing switch ON must be operated immediately after the

dead centre position of the toggle spring mechanism is reached in the closing process and the

automatic rapid closing process has started;

3. Auxiliary limit switch 11.3 (Q8S1) for earthing switch OFF must:

a) be operated on earthing switches with manual mechanisms during the opening movement of the

slide 14.2 before half of the hexagonal shaft has become visible, or 1 mm before the tab of the

slide makes contact with the armature of the de-energised locking magnet;

b) be operated on earthing switches with motor operators (no slide 14.2 fitted) immediately after the

toggle spring mechanism has passed the dead centre position during rotation to the OFF position.

Note

Check the direction of rotation of the motor after repair work.

Do not allow the motor to run up against a lock if the direction of rotation is incorrect (also see section

7.5.4).

A spare parts list is available on request for procurement of spare parts. It basically includes moving
