Prevent restart

To prevent the machine restarting (unintentionally) while there is someone inside the
danger zone, a padlock can be attached via the through hole on the actuator (see diagram).
As a result the actuator cannot engage with the safety switch, guard locking is not activated
and the machine is prevented from starting.

If the actuator is to blocked using several locks in parallel, a multiple lock can be used
