Install the switch that activates the override in a location that provides a clear
view of the entire hazardous area and where it cannot be activated from within
the hazardous area. Make sure that nobody is in the hazardous area before
activating the override function.
Do not place fluorescent and/or incandescent lights within the effective aper-
ture angle of the receiver, as it may influence the F3S-TGR-CL system under
certain circumstances.
Install the sensor system so that it is not affected by any reflective surfaces.
Failure to do so may hinder detection, resulting in serious injury.
When using more than 1 set of F3S-TGR-CL system, install them so that
mutual interference does not occur, such as by configuring series connections
or using physical barriers between adjacent sets.
Make sure that the F3S-TGR-CL system is securely mounted and its cables
and connectors are properly connected.
Make sure that foreign objects such as water, oil, or dust do not enter the
inside of the F3S-TGR-CL system while the cover for the selector switches is
open and tighten the screws of the cover firmly after changing the settings.
Do not use the sensor system with mirrors in a retro-reflective configuration.
Doing so may hinder detection. It is possible to use mirrors to "bend" the
detection zone to a 90° angle.
Perform an inspection for all F3S-TGR-CL systems as described in the chap-
ter "Checkout and test procedure". When using series connections, perform
inspections for every connected F3S-TGR-CL system.
Do not short-circuit the output line to the +24 V line. Otherwise, the output is
always ON. Also, the 0 V of the power supply must be grounded so that the
output does not turn ON due to grounding of the output line.
Configure the system by using the optimal number of safety outputs that sat-
isfy the requirements of the necessary safety category.
Do not connect each line of F3S-TGR-CL system to a DC power supply of
more than 24 VDC+20%. Also, do not connect to an AC power supply. Failure
to do so may result in electric shock.
