I Indication and Output
When the product is purchased, “ful” will be indicated. As electro-
lytic capacitors deteriorate, indication changes to “hlf”. After the
remaining time to maintenance is reduced to two years, indication
automatically changes to a value, which decreases from “1.5” to “1.0”
to “0.5” to “0” (year) as the running hours increase.
If the maintenance forecast monitor setting is set to a value larger
than two years, value indication automatically begins after the
remaining time to maintenance is reduced to the set years.
If the remaining time becomes smaller than setting L (which can be
set arbitrarily between 0 and 5.0 years), an alarm (a02) and the
remaining time are indicated alternately.
With the S8VS-09024A, an output is given to an external device from
a transistor ((12) Yrs) to notify of the replacement timing, together
with indication. (The output is turned off after the replacement timing
is reached; with no continuity across (12) and (13).)
In the case that the
remaining time is reduced
to smaller than 0.5 year
and an alarm is issued.
Note: 1. The remaining time to maintenance is based on continuous
operation, not including the time when the power supply is
turned off, and so may take longer to reach than the actual
time indicated.
2. Until the power supply has been turned for about one month
in total, indication is fixed at “ful” to estimate the extent of
deterioration, while the output remains turned on (with con-
tinuity across (12) and (13)).
