Quick Installation Manual
7. Pre-Operation Checklists / Maintenance Checklists
After wiring, mounting and beam alignment are done, check the operation of the F3SJ-B-01T.
Pre-Operation Checklists
After installation, the highest level administrator must use the following checklist to verify the operation, plac-
ing a check mark in each of the boxes.
■Checklists
- Installation Condition Check
□The machine itself does not prevent the operation of safety functions such as stopping.
□The hazardous part of a machine cannot be reached without passing through the detection zone of the
F3SJ-B-01T.
□The system is configured so that the F3SJ-B-01T can always detect a worker who is working in the haz-
ardous zone.
□The interlock reset switch is installed in a location that provides a clear view of the entire hazardous zone
and it cannot be activated from within the hazardous zone.
□Safety distance has been calculated. Calculated distance: S = ( ) mm
□The actual distance is equal to or greater than the calculated distance. Actual distance = ( ) mm
□Reflective surfaces are not installed in prohibited zones.
□Not installed in a reflective configuration.
□Not used in flammable or explosive atmosphere.
- Wiring check before power is turned ON
□Sharing the power supply with other devices may cause the F3SJ-B-01T to be affected by noise or volt-
age drop. It is recommended that this safety component use a dedicated power supply but do not share
with other devices.
□The power supply unit provides 24 VDC while complying with the EMC Directive, Low Voltage Directive,
output holding specification.
□The power supply polarity is not connected in reverse.
□Emitter/receiver cables are properly connected to the respective emitters/receivers.
□Double insulation is provided between input/output and hazardous voltage (commercial power source,
etc.).
□Outputs are not short-circuited to 0 V line.
□Loads are not connected to the 0 V line.
□All lines are not connected to commercial power source.
□Model of emitter and receiver must be the same.
□When two or more sets of F3SJ-B-01Ts are used, they are series-connected or mutual interference pre-
vention measures are taken.
□When 2 or more sets of F3SJ-B-01T are used in series connection, they must not be connected to a sen-
sor other than F3SJ-B-01T.
□A cap is attached to the secondary sensor that is located farthest from the power supply.
□Neither connector nor bracket must be loose.
□Auxiliary output must not be used as safety output.
□Power supply's +24 V must be grounded.
□Wiring must not be bent, cracked, nor damaged.
-Operation Check While the Machine Is Stopped
□The test rod is not deformed.
Depending on the unit's model and settings of floating blanking function, detection capability may vary.
Use a test rod with an appropriate diameter for inspection. The model name of test rod is as follows.
