 Load Switching Frequency
 Overview
This value represents load switching frequency connected to F3SJ.
 Functional Description
The number of times the F3SJ safety output has switched from ON to OFF is recorded in the F3SJ
main unit every 15 minutes. The record is made when in normal operation or during lockout. By
monitoring the number of times the safety output has switched from ON to OFF, you can understand
the number of responses that have been made by the relays and contactors connected to the F3SJ.
• Load switching frequency
This value represents load switching frequency connected to F3SJ. In the case of series connection,
load switching frequency can be displayed for each F3SJ CH.
• Load switching frequency threshold value
When load switching frequency exceeds this value, output can be performed to the auxiliary output
or the external indicator output.
Note that excess load switching frequency information must be assigned to an output operation
mode.
- Auxiliary Output (Non-Safety Output) p.94
- External Indicator Output (Non-Safety Output) p.98
• Accumulated load switching frequency
This value indicates the cumulative value for load switching frequency, from the time that power was
first supplied to the F3SJ until the present.
It is not possible to reset this value using load switching frequency reset function.
• Load switching frequency reset
This function resets load switching frequency recorded in the F3SJ. Use this reset function
whenever you install or replace relays or contactors.
