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.
Items to Inspect Every 6 Months or When Machine Settings Are Changed
In addition to inspection item at operation start, following items must also be verified.
The outputs of the F3SJ and the machine are properly wired.
The total number of times that the control relays/contactors have switched is significantly lower than
their design lives.
There is no disturbance light.
When F3SJ is connected again, a secondary sensor farthest from its power supply has either of the
followings:
- Cap
- Key cap for muting
- Muting lamp (set of lamp and cable)
Power supply's 0V must be grounded.
