When the Main Unit reaches the time when it can no longer exhibit sufficient performance due to the
degradation of characteristics of the electrolytic capacitor inside the Main Unit, the display on the Main
Unit and the communications status change. Use this function to know the approximate replacement
time of the Main Unit.
Note The replacement timing announcement indicates a guideline that the Main Unit cannot achieve sufficient
performance due to deterioration of the electrolytic capacitor. The guideline does not include failures
caused by other factors.
When the Main Unit reaches the approximate replacement time, it will be notified by the following meth-
ods.
• The AGE indicator on the Main Unit front-panel that displays the status lights to notify users when to
replace.
(Note) Turn ON the Use Running Time, so that the AGE LED lights up when the guideline for the
replacement time is reached. The default setting of the Use Running Time is OFF.
• The Running Time bit ON in the Main Unit status notifies users when to replace. It can be read
through communications.
The changed setting parameter is enabled after power is again supplied to the Main Unit, or after soft-
ware reset.
An operation example of an alarm is described below.
The operation performed under the following general conditions is as described below.
Conditions: When the threshold value is such that threshold 2 > threshold 1, there is no alarm latch,
and there is no arrival prediction
Example:
Note The above example is for a case when there is one current value. In actuality, individual alarm determina-
tion is performed based on multiple current values, and the result of OR logic is reflected in status display
and transistor output as a comprehensive alarm.
