IOB LVD Number
(LVD Connector)
For IOBGP I/O boards, set to:
1, if the contactor is connected to XH4

See Input / Output Board on page 3.
Type
Set according to the type of contactor:
Normally Open
if contacts are open when coil
voltage is zero, or for latched contactors, which
open or close on current pulses.
Normally Closed
if contacts are closed when coil
voltage is zero.
Normally closed LVD contacts require special
system wiring when used to disconnect the
battery.
Smart Alarm Disconnect
An LVD control channel can be set to disconnect if a specified
Smart Alarm
becomes active. For
example, a battery LVD can be set to disconnect if the battery temperature is too high, or a load
LVD can be set to disconnect when
Ah Discharged
exceeds a defined value.
An unwanted LVD disconnect may occur if
Smart Alarm Disconnect
uses a sensor which
becomes faulty or disconnected.
An unwanted LVD disconnect may occur if
Battery Time Remaining
is used as a source
for Smart Alarm Disconnect.
