turned ON, and calculates the level of deterioration of the electrolytic capaci-
tor from the operating time and internal temperature. The replacement notifi-
cation function displays the approximate time until the Power Supply Unit will
stop functioning at its full capacity due to the characteristic deterioration of the
electrolytic capacitor, based on the calculated level of deterioration. When 6
months are remaining until replacement is required, the alarm output will turn
OFF.
Note The replacement notification function provides an indication of when the dete-
rioration of the electrolytic capacitor will prevent the power supply functioning
at its full capacity. It does not provide information on failures occurring due to
other causes.

The replacement notification for of the Power Supply Unit is shown using
three 7-segment LED displays.
• At time of purchase "FUL" is displayed. The display changes to "HLF" as
the electrolytic capacitor deteriorates ("HLF" may not be displayed,
depending on the operating environment).
• When the time until replacement is required drops below 2 years, the dis-
play will change corresponding to the operating time from "1.5" to "1.0" to
"0.5" to "0.0"/"A02." When the remaining service life reaches 6 months or
less, the display will alternate between "0.0" and "A02" in 2-second inter-
vals.
