Sensor Tests
The technician should test the functionality of each sensor by blocking the sensor and watching
its state change on the front panel.
Note: Several jam sensors only change state if a jam has occurred. All doors (interlock
switches) must remain closed or defeated to test for a changed state. To update the sensor
status, open and close the Interlock.
