Description
Where to find:
Voltage Based
Disconnect
If
Enabled
, the LVD will disconnect if the bus
voltage has been below the
Disconnect Voltage
for
the
Recognition Time
and reconnect if the bus
voltage has been above the
Reconnect Voltage
for
the
Recognition Time.

AC Timer Based
Disconnect
If
Enabled
, then during an ac supply failure the
LVD will disconnect after the
AC Timer Delay
,
even if the
Disconnect Voltage
has not been
reached.

Smart Alarm Based
Disconnect
If
Enabled
, the LVD will disconnect when the
Smart Alarm
specified by
Smart Alarm Index
becomes active.

(Chaining)
If
Enabled
, the LVD channel will only disconnect
if one of its disconnect conditions is true and the
preceding LVD channel has been disconnected
for the
Recognition Time.
This applies in reverse
when reconnecting.
Does not apply to LVD 1.
* If the LVD channel operates contactors used as a load-disconnect, ensure the Reconnect Voltage
is set higher than the expected open-circuit recovery voltage of the discharged batteries.
