OPERATING THE AT10.1

2.3.6. Enabling the High DC Voltage shutdown feature
The AT10.1 has a built-in High DC Voltage Shutdown feature. In case of
any maladjustment or internal failure that results in a continuous output
voltage that is too high, the AT10.1 shuts down after 30 seconds to protect
the battery. The front panel meter displays code
E 03
, and the summary
alarm relay contact (TB3) transfers.
NOTICE
The AT10.1 is normally shipped from the factory with the
High DC Voltage Shutdown feature
disabled .
You can adjust the high dc voltage shutdown
(the setting is the same as the high dc voltage
alarm setting). Refer to Section 2.3.4.
To enable the shutdown feature:
•
The AT10.1 must be in normal operation (not
the Edit Mode ) to enable HVDC Shutdown.
•
Press and hold the
UP
key, then...
•
Press the
CHRG MODE
key.
The HIGH DC VOLTAGE indicator lights, and
the display flashes
ON
. You can toggle the
shutdown feature OFF and ON by pressing the
CHRG MODE
key repeatedly.
Parallel Operation
If two (or more) AT10.1s
are connected in parallel,
both sense the output
voltage. If one AT10.1 runs
away, it will supply all the
output current. The other
will have zero output
current. The high dc
voltage shutdown does not
operate in an AT10.1 with
zero output current, so that
only the
defective AT10.1
(of two or more in parallel)
shuts down. The other
AT10.1 will continue to
supply the load normally.
If you do not press any key within 4 seconds, the last state indicated (
ON
or OFF ) is saved internally. Note that you do not use the
EDIT/ENTER
key
for this feature.
If the AT10.1 shuts down because of a high dc voltage, the meter displays
error code
E 03 . Reset the AT10.1 by turning the ac input circuit breaker
(CB1) off, then on again.
