5.1 Overview
This chapter contains operational test procedures, troubleshooting, cleaning, and
maintenance, instructions.
IMPROPER MAINTENANCE
Strictly adhere to all maintenance and troubleshooting instructions.
Failure to comply with these instructions could result in death or serious injury.
5.2 Operational Test
To ensure operational readiness, perform the operational test at least once a day and
every time the light curtain is repaired or powered up. The operational test consists of
passing a test rod (included with the FF-SYA14 or FF-SYA30 units) or the hand (for the
FF-SYA60 units) through the sensing field to ensure the light curtain will detect it (see
figure below). The sensing function of the light curtain shall be actuated by moving the
relevant test rod at a maximum speed of 2.5 m/s for the FF-SYA14 and the FF-SYA30 (or
by moving the hand at a maximum speed of 1.6 m/s for the FF-SYA60). The included test
rod will have a diameter equal to the resolution of the light curtain. The resolutions of the
FF-SYA Series light curtains are as follows:
