a. Manual Reset
The DC power system can be configured with
automatic
or
manual
alarm reset.
When
Manual Alarm Reset
is enabled -- and the alarm condition no
longer exists -- the operator must reset the alarm manually, via the
power systems user interface (web GUI or controller’s front keys).
When the Manual Alarm Reset is disabled, then the
Automatic Alarm
Reset
is enabled (default). In this case, when an alarm condition no
longer exists, the main controller will automatically reset the alarm,
by deactivating the alarm lamps and relays to indicate that normal
operation is established.
b. Hysteresis and Time Delay

c. Mains Independent
Check this option if you want that the LVD alarm monitor will reconnect
the LVD contactor when the rectifier system output voltage reaches
the Reconnect Voltage limit, regardless whether Mains is ON or OFF. For
example, this is possible using an additional primary supply.
Uncheck this option (Mains dependent) if you want that the LVD alarm
monitor will NOT reconnect the LVD contactor until Mains is ON again.
d. Temperature Dependent
Used with LVD contactors that disconnect the battery bank (LVBD).
Check this option if you want that the LVD alarm monitor will reconnect
the LVBD contactor when the battery temperature is lower than the
temperature limit configured in the “BatteryTemp” alarm monitor.
e. Disconnect Voltage
Enter a numeric value for the battery voltage drop-down limit. When --
after a Mains failure -- the battery voltage gradually drops down to this
limit; then the alarm monitor raises the alarm and trips the LVD contac-
tor.
f. Reconnect Voltage
Enter a numeric value for the battery voltage reconnection limit. When
the Mains supply is ON again, the rectifier system output voltage in-
creases to this limit; then the alarm monitor will reconnect the LVD
contactor.
g. Delay Time after Disconnect
Enter the Time delay or number of seconds the LVD contactor has to
be tripped or disconnected, before the alarm monitor is allowed to
reconnect the LVD contactor
