Mounting Considerations
This section discusses optical alignment and mounting considerations. There are several different ways to mount the FF-SYA
Series light curtains (singularly, in groups, and in several different orientations).
3.8.1
Optical Alignment
Proper optical alignment of the FF-SYA Series light curtains ensures optimum operation. The emitter and receiver units must be
mounted in parallel, at the same height, and with an angular displacement of no more than ± 2,5
o
. See figure below for proper
alignment.

IMPROPER INSTALLATION OF FF-SYA SERIES LIGHT CURTAIN
•
Mount FF-SYA Series light curtains so that any entry into protected area must interrupt sensing field of the safety light curtain
or activate other safeguarding devices.
•
Install mechanical guards or additional FF-SYA light curtains to prevent operating personnel from reaching around, under, or
over the sensing field.
Failure to comply with these instructions could result in death or serious injury.
Vertical mounting may require the installation of mechanical guards or additional light curtains to prevent operating personnel
from reaching around, under, or over the sensing field.

< 70 mm / 2.75 in
For point-of-operation guarding, the light curtain(s) and any mechanical guards must be installed to detect or prevent operating
personnel from standing between the light curtain and the danger zone (see Figure 3-12 et Figure 3-13).
