Checklists
 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, all 5 incident light level indicators
turn OFF, and the OFF output indicator turns ON.
Use an appropriate test rod based on the type code and floating blanking function for inspection.
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 status can be checked from where a worker operates or adjust
the machine.
 Neither connector, cap, or 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 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.
 Safety distance has been calculated with changed detection capability when floating blanking is
changed.
Calculated distance: S = ( )mm
 When muting function setting is changed, a muting sensor must be installed so that muting state
should not occur when a human body enters a detection zone of F3SJ by mistake.
 When muting function setting is changed, a muting sensor must be installed so that muting state
should not occur when a human body enters a hazardous zone of a machine.
 When muting function setting is changed, a muting sensor must consist of 2 independent devices.
 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 24V must be grounded.
 Wiring must not be bent, cracked, nor damaged.
