Scanning Ranges
The Nominal scanning range is the maximum distance allowed between the emitter and the receiver. A selector switch is
available on the emitter unit for the selection of the adequate emission power. Refer to the chapter 3.6 Mutual Interference or
cross-talk for correct adjustment.
The FF-SYA Series light curtains have the following scanning ranges:

MINIMUM SCANNING RANGE (FF-SYA14, FF-SYA30 and FF-SYA60 only)
Using the FF-SYA14, FF-SYA30 or FF-SYA60 light curtains below the specified minimum scanning range will maintain the
light curtain in a lock out condition. To go back to normal conditions of operations, switch the power off, move away the
receiver from the emitter, then restore the power.
IMPROPER MINIMUM SCANNING RANGE (FF-SYA234 only)
Always install the FF-SYA234 multibeam systems at a distance superior to the minimum value of the selected scanning range
or select a lower scanning range on the emitter. When installed at a distance below the specified minimum scanning range,
the FF-SYA234 multibeam systems for access detection may NOT comply with IEC/ pr EN 61496-2 optical requirements for
aperture angle.
Failure to comply with these instructions could result in death or serious injury.
