Figure 2-1 Point-of-operation Guarding (use FF-SYA14 and FF-SYA30 only)
Point-of-operation is defined as that area where a machine performs work (such as cutting, shaping, boring, or forming) on a
material.
FULL REVOLUTION MECHANICAL POWER PRESSES CANNOT BE STOPPED IN MID-STROKE (OSHA 29CFR
1910.217).
DO NOT use FF-SYA Series light curtains on full revolution mechanical power presses.
Failure to comply with these instructions will result in death or serious injury.
For point-of-operation guarding, the light curtain(s) and any mechanical guards should be installed so no one can stand
between the light curtain and the danger zone. This may require additional hard guarding, horizontal or angled positioning of
the light curtain, or additional light curtains.
Figure 2-2 Point-of-operation Guarding (use the FF-SYA14 and FF-SYA30 light curtains only)
IMPROPER POINT-OF-OPERATION PROTECTION
Do NOT use FF-SYA60 Series light curtains or the FF-SYA234 multibeam systems in point-of-operation applications.
Failure to comply with these instructions will result in death or serious injury.
