The test rod is detected when it is moved around in the detection zone as shown in the diagram below.
In other words, when a test rod is inserted into the detection zone, the stable-state indicators (STB)
turn off and the ON/OFF-state indicators turn red.
Confirm that hazardous parts should stop while the machine is operating, as shown below.
When muting function is used, installation condition of muting sensor must not be changed.
When muting function is used, muting state can be checked from where a worker operates or adjust
the machine.
Neither connector nor bracket must be loose.
 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 three
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-E/B is turned OFF while nothing is in the
detection zone.
 Items to inspect every six 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-E/B 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-B is connected again, a secondary sensor farthest from its power supply has either of the
followings:
•Cap
•Key cap for muting
Power supply's 0 V must be grounded.
Wiring must not be bent, cracked, nor damaged.
