What can be done by the setting tool
 Functional Description
• Warning Zone Function
Incidence or interruption to a warning zone will not affect safety output operation. When an output
operation mode of auxiliary output or external indicator output is configured as a warning zone, its
unblocked/blocked status can be output.
- Auxiliary Output (Non-Safety Output) p.94
- External Indicator Output (Non-Safety Output) p.98
• Warning Zone Setting
You can teach a warning zone by interrupting beams to be set as the zone, or manually specify
number of beams from top or bottom beam. (figure 1 & 2)
For manual specification, configure beam number in case of the PC tool for F3SJ, or number of beams
in case of the setting console.
Configuration cannot be executed for cases shown below.
•All beams are configured as a warning zone (figure 4).
•A warning zone is specified without including any of end beams (figure 5)
Note that a warning zone can be configured for all beams if series connected F3SJs have one or more
normal beam. (Figure 3)
