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 the installation is changed. 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 or the FF-SYA234 multibeam systems) through the sensing
field to ensure the light curtain will detect it (see
Figure 5-1
). 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 and the FF-SYA234). The included test rod will have a
diameter equal to the resolution of the light curtain.
