F3S-B

MAINTENANCE

Do not use the F3S-B until the following inspections are completed.
Failure to do so may result in loss of life or serious injury.
Do not disassemble, repair or modify the F3S-B.
Note:
1. For Safety, be sure to record and store inspection results.
2. Make sure you are thoroughly familiar with the F3S-B and the machine prior to conducting an inspection.
3. Make sure all personnel have adequate guidelines for performing maintenance and inspections.
4. Check all items in "3-2 Check List" again if the protective structures preventing access to the hazard
are changed.

6-1 Daily Inspections

Be sure to inspect the following items at the start of work or after a shift change.
1. % No intrusion paths into a hazardous part of a machine except through the F3S-B detection zone.
2. % Some part of the operator's body remains in the F3S-B detection zone at all times while the operator
works in the hazardous area.
3. % The actual safety distance is greater than the calculated distance.
4. % No dirt or scratches on the optical surface.
Operate the machine and check to see if the hazardous part stops under the conditions below.
5. % The hazardous part moves when there is nothing in the detection zone (normal operation).
6. % The hazardous part stops within the calculated time when the test rod is inserted into the detection
zone directly in front of the emitter, directly in front of the receiver and midway between the emitter
and receiver.
7. % The hazardous part remains stopped as long as the test rod is present in the detection zone.
8. % The hazardous part stops when the F3S-B power supply is turned OFF.

6-2 Inspection Every Six Month

Inspect the following items every six months or when a machine setting is changed.
1. % Machine structure does not hinder stop and safety functions.
2. % There is no machine modification or connection change that will adversely affect the control system.
3. % The F3S-B outputs are correctly wired to the machine.
4. % The actual overall response time of the machine is less than the calculated response time.
5. % The control relay and connector are in good condition.
6. % The brackets are securely tightened.

6-3 Cleaning

If the surface of the F3S-B is extremely dirty, F3S-B will stop activating outputs. In this case, use a clean soft
cloth and clean the surface without pressure. Do not use any solvents such as paint thinners, benzene or
acetone to clean the F3S-B because they will damage the translucent surface.
