9.2.3 Setting SA3.1
The break contact with contacts 11 and 12 is used to monitor the position of the brake
shoes. With the brake open, the switch is closed.
The make contact closes contacts 23 / 24 only when the wear limit of the brake linings
has been reached and the brake is closed. The contacts must be switched in such a
way that when one contact of both switches closes the drive is prevented from starting
up.
With a correctly set brake test switch, all switch contacts must be interrupted with a
closed brake.
Before starting to set the sensor; the stroke of the brake shoes must be adjusted!
