Checking that Hazardous Parts Stop While the Machine Operates
The hazardous parts are movable when nothing is in the detection zone.
The hazardous parts stop immediately when a test rod is inserted into the detection zone at 3
positions: "directly in front of the emitter", "directly in front of the receiver", and "between the emitter
and receiver". (Use the appropriate test rod.)
The hazardous parts remain stopped as long as the test rod is in the detection zone.
The hazardous parts stop when the power of the F3SJ is turned OFF while nothing is in the detection
zone.
