IMPROPER PRESENCE SENSING PROTECTION
•
Install FF-SYA Light Curtains and mechanical guards so NO person can stand between light curtain and danger zone
without being detected.
•
DO NOT install the FF-SYA60 Series light curtains at a height lower than 150 mm/5.90 in above the floor.
•
DO NOT use the FF-SYA234 multibeam systems for presence sensing protection.
Failure to comply with these instructions will result in death or serious injury.

IMPROPER PRESENCE SENSING PROTECTION
•
Install FF-SYA Light Curtains and mechanical guards so NO person can stand between light curtain and danger zone
without being detected.
•
DO NOT install the FF-SYA60 Series light curtains at a height lower than 150 mm/5.90 in above the floor.
•
DO NOT use the FF-SYA234 multibeam systems for presence sensing protection.
Failure to comply with these instructions will result in death or serious injury.
IMPROPER INSTALLATION FOR POINT-OF-OPERATION
To prevent operating personnel from access to danger zone, install hard guard or right-angle mounting if distance between
danger zone and closest light beam is greater than 70 millimetres (2.8 in).
Failure to comply with these instructions could result in death or serious injury.
For point-of-operation guarding, the safety light curtain(s) and any hard guarding must be installed so that no person can stand
between the light curtain and the danger zone without being detected. Installation may require additional hard guarding,
horizontal or diagonal mounting of the light curtain, or additional light curtains mounted at right angles to each other.

< 70 mm / 2.8 in
A right-angle mounting arrangement may be used if the altered resolution at the joint is acceptable to the local regulatory
agency. The emitters and receivers units should be mounted with opposite orientations to prevent mutual interference or cross-
talk (see Figure 3-19).
