Cleaning
The FF-SYA Series light curtains and mirrors are designed to operate in harsh industrial environments. Exposure to
dirt, dust, grease, and oil are unavoidable in these harsh environments. Periodically clean the emitter/receiver units
and mirrors. This section provides specific, step by step, instructions on the proper cleaning techniques for the FF-SYA
Series emitters, receivers, and mirrors.
5.4.1
Using a Dry Cloth
Clean dust or loose, dry dirt from the emitter and receiver units using a soft, clean, non-abrasive cloth.
POWER APPLIED TO MACHINE CONTROL SYSTEM
Turn off and disconnect power from FF-SYA Series light curtain and machine.
Failure to comply with these instructions could result in death or serious injury.
1.
Turn off and disconnect power to both the light curtain and the machine.
2.
Gently wipe the soiled areas with a soft, clean, non-abrasive cloth. Do not rub hard to prevent scratching the clear
plastic front plate or finish. If the dirt will not wipe off with a dry cloth, clean units with a soap and water solution.
See Using Soap and Water below.
3.
Connect power to the machine and light curtain.
4.
Perform the operational test to ensure proper functional readiness.
