2-26-4. Power-ON Time
The user can view the following information related to the power-on time of the F3SG-SR. The power-
on time information is recorded in the F3SG-SR main unit every 15 minutes. This information is useful
to better understand when to schedule of the F3SG-SR.
• Power-on time threshold
It is possible to give an output signal to the auxiliary output or indicate with Area Beam Indicator (ABI)
when the power-on time exceeds the power-on time threshold. The excess power-on time information
must be assigned to the output operation mode of the auxiliary output or Area Beam Indicator (ABI).
For the details of the information assigned to the auxiliary output, refer to 2-12. Auxiliary Output.
• Power-on time
This is the current power-on time since the power-on time was last reset. If the power-on time has
never been reset, this value is the same as the accumulated power-on time. The information is
displayed for the emitter and receiver, respectively.
• Accumulated power-on time
This is the cumulative power-on time, from when the F3SG-SR is powered on for the first time after
purchase until the present. It is not possible to reset this value by the power-on time reset function.
• Power-on time reset
This function can reset the power-on time of the F3SG-SR to zero. When the F3SG-SR is in cascade
connection, the power-on time can be reset for each cascaded F3SG-SR segment.
The user can make changes to the settings by the SD Manager 3.
2-26-5. Load Switching Frequency
The user can view the number of switching operations of the load connected to the F3SG-SR. The
load switching frequency information is recorded in the F3SG-SR main unit every 15 minutes. This
information is useful to understand the switching frequency of relays and contactors connected to the
F3SG-SR.
• Load switching frequency threshold
It is possible to give an output signal to the auxiliary output or indicate with Area Beam Indicator (ABI)
when the switching frequency exceeds the switching frequency threshold. The excess load switching
frequency information must be assigned to the output operation mode of the auxiliary output or Area
Beam Indicator (ABI).
For the details of the information assigned to the auxiliary output, refer to 2-12. Auxiliary Output.
• Load switching frequency
This is the switching frequency of the load connected to the F3SG-SR. When the F3SG-SR is in
cascade connection, the load switching frequency can be reset for each cascaded F3SG-SR segment.
• Accumulated load switching frequency
This is the cumulative load switching frequency, from when the F3SG-SR is powered on for the first
time after purchase until the present. It is not possible to reset this value by the load switching
frequency reset function.
• Load switching frequency reset
This function can reset the load switching frequency of the F3SG-SR to zero. When the F3SG-SR is in
cascade connection, the load switching frequency can be reset for each cascaded F3SG-SR segment.
Use this reset function whenever you install or replace relays or contactors.
