3.7 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).
3.7.1 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 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 figures belows).
