)
Displays when the maintenance forecast has reached the set value.
Indication and Output
When the Product is purchased, “
ful
” will be indicated. As
electrolytic capacitors deteriorate, indication changes to “
hlf
” (Refer
to page 30). “
ful
” will be indicated for the maintenance forecast
display for approximately one month after the Power Supply is first
turned ON. The accumulated value will then be displayed depending
on the ambient conditions thereafter. (However, the “
hlf
” indication
may not appear, depending on the usage environment and the set
value for maintenance forecast.)
S8VS-06024A:
After the remaining time to maintenance is reduced to less than two
years, indication automatically changes to a value, which decreases
from “
1.5
” to “
1.0
” to “
0.5
” to “
0.0
” (year) as the running hours
increase. If the remaining time becomes less than 0.5 year, an alarm
(
a02
) and “
0.0
” are indicated alternately.

If the maintenance forecast setting L (which can be set arbitrarily from
0.0 to 5.0 years in 0.5-year steps) is set to a value larger than two
years, the indication automatically changes to a value (L - 0.5) after
the remaining time to maintenance is reduced to the set years, and an
alarm (
a02
) and the remaining time are indicated alternately.
If the setting is less than 2.0 years, the indication changes to a value
(
1.5
) after the remaining time becomes less than two years, and after
the remaining time becomes less than the set time, an alarm (
a02
)
and the remaining time (L - 0.5) are indicated alternately.
If the alarm (
a02
) and a numeric value are indicated alternately, a
transistor (maintenance forecast output terminal (Yrs)) will turn OFF
to indicate the need for maintenance. (The transistor turns OFF when
the maintenance forecast time is reached, i.e., there will be no
continuity at the maintenance forecast output terminal.)
Note: 1.
The remaining time to maintenance is based on continuous
operation, not including the time when the power supply is
turned OFF.
2.
“
ful
” will be indicated until approximately one month of
time is accumulated to estimate the speed of deterioration
and the output will remain ON (continuity at the
maintenance forecast output terminal (Yrs)).
