Features
Protective Height Available in Incremental
Sizes
Easy-to-Read Light Level and Error Mode
Display
Beam alignment is simplified using 5 LEDs that display the incident light
level.
Error status is indicated on 3 additional LEDs when an error occurs.
Indicator Display Patterns p.7
Additional Safety Functions
•External test (light emission stop)
•External device monitoring function
Enhanced Mutual Interference Prevention
When the series connection function is used, mutual interference is prevented in up to 240 beams in 3
sets.
When F3SJ are used individually, the newly designed interference light detection and cycle shift
algorithm prevents mutual interference in up to 3 sets.
Muting/Override Function are Provided
An F3SJ by itself can operate with muting or override function without using a controller.
Definition of muting function and override function p.125
