S8T-DCBU-01
When
S8T-DCBU-01
is used
The backup state is not
returned to even after the
power is restored from a power
failure.
A probable cause is that a protection
function on the S8TS-06024
was
activated to stop S8TS-06024
operation.
Cancel the protection functions on the
S8TS-06024
. (Turn OFF the power of
S8TS-06024
Basic Block, and after at
least one minute turn ON the input voltage
again.)
Output was cut during backup
operation.
A probable cause is that the overdischrge
protection function was activated by
battery voltage dropping due to discharge.
If a remedy is required during backup
operation, allow backup to finish until the
battery status indicator lit.
A probable cause is that an overcurrent
state is reached due to load fluctuations
during backup operation.
Provide sufficient margin for the load
capacity when using the S8T-DCBU-01.
Backup operation and regular
operation are alternately
repeated.
A probable cause is that one of the S8TS-
06024
s is out of order when two or more
S8TS-06024
s are connected.
Replace the out-of-order S8TS-06024
.
Refer to
Backup
on page 3 for details.
A probable cause is that the S8TS-
06024
is in an overcurrent state due to
load fluctuations during regular operation.
Provide sufficient margin for the load
capacity when using the S8T-DCBU-01.
When inspecting
batteries
Backup time is too short.
A probable cause is that the battery has
reached the end of its service life.
We recommend periodically replacing the
battery.
Refer to
Replacing Batteries
on page 9 for
details.
A probable cause is that the S8T-DCBU-
01 was stored for a long time with the
battery connected.
Storing the S8T-DCBU-01 with the battery
connected may considerably shorten the
service life of the battery due to leakage
current from equipment. When storing the
S8T-DCBU-01, first disconnect the
battery.
A probable cause is that battery
characteristics caused the backup time to
shorten in low temperatures.
Check the backup time in the operating
environment before use.
The voltages of the two
batteries used in series are
considerably different.
A probable cause is a battery abnormality. Replace both batteries.
