F3SJ-A-TS
Quick Installation Manual
6. Pre-Operation Checklists / Maintenance Checklists
After wiring, mounting and beam alignment are done, check the operation of the F3SJ-A-TS.
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-A-TS.
□The system is configured so that the can always detect a worker who is working in the hazardous 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.
□When muting function is used, a muting sensor must be installed so that muting state should not occur
when a human body enters a detection zone of F3SJ-A-TS by mistake.
□When muting function is used, 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 is used, muting state can be checked from where a worker operates or adjust the
machine.
□A muting sensor consists of 2 independent devices.
□It is not used in flammable or explosive atmosphere.
- Wiring Check Before Power Is Turned ON
□When the power supply unit is connected to multiple devices, the power supply unit must have tolerance
against total rated current of the devices.
□The power supply unit is a 24 VDC unit that conforms to the EMC Directive, Low-voltage Directive, and
output holding specifications.
□The power supply polarity is not connected in reverse.
□Emitter/receiver cables are properly connected to the respective emitters/receivers.
□Double insulation is used between I/O lines and the hazard potential (commercial power supplies, etc.).
□Outputs are not short-circuited to the +24V line.
□Loads are not connected to the +24V line.
□All lines are not connected to commercial power source.
□F3SJ-A-TS's power supply connector and series connection connector must not be attached upside
down.
□Model of emitter and receiver must be the same.
□When 2 or more sets of F3SJ-A-TS are used, series connection is made or mutual interference preven-
tion measures are taken.
□When 2 or more sets of F3SJ-A-TSs are used in series connection, PNP output type and NPN output
type must not be connected.
□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)
□Neither connector, cap, or bracket must be loose.
□Auxiliary outputs 1 and 2, and external indicator outputs 1 and 2 must not be used as safety output.
□Power supply's 0V must be grounded.
□Wiring must not be bent, cracked, nor damaged.
-Operation Check While the Machine Is Stopped
□The test rod is not deformed.
