Setting the Maintenance Forecast Monitor Detection Threshold: LFE (Life)
The Maintenance Forecast Monitor Detection Threshold Setting (LFE) will be
displayed if the Up (SEL) Key ( ) is pressed from the Undervoltage Detec-
tion Threshold Setting Display (V-U).
Note The maintenance forecast monitor output is an estimate of the lifetime of the
electrolytic capacitor in the power supply circuit. It is calculated from the
power-ON time and internal temperature. When the estimated lifetime falls
below the threshold value, the maintenance forecast monitor output (LFE)
photoswitch output will turn OFF, and the seven-segment display will alter-
nately show error code A23 and the remaining lifetime (in 0.5-year incre-
ments).

This parameter sets the maintenance forecast monitor output.
Press the Key to display the set value (SV). The SV
can be changed by pressing the and Keys.
The setting range is 0 to 5 years, in 0.5-year increments.
• If the or Key is pressed for more than 2 s, the
SV will change in 1.0-V increments instead of 0.5-V
increments.
Change the SV with the and Keys.
The S8AS will automatically return to the LFE display if
no key is pressed within 3 s.
When the Key is pressed, the SV display will flash.
When the flashing stops, the new setting will be saved
and the S8AS will return to LFE display.
If you want to confirm the new setting, press the Key
