Test Point 13

Position Switch On Drive Closed During Activation

- Check triggering of actuators. Ground must be present at connectors T27 and T28, terminals 1 and 7, in the quiescent state.

Note: Positive voltage must be present at terminal 7 when the actuator is triggered in "open" direction. Positive voltage must be present at terminal 1 when the actuator is triggered in "closed" direction. Check directly at actuators if required.

Note: The actuators are only triggered for several milliseconds.

- Check wires from alarm control unit plug I, terminals 11 and 12, to the actuators for continuity.

- Check position switch at actuator, Test Point 4
