Start DCV 30 sec
Full Name Starting Battery Voltage—30 seconds
Purpose The “Start DCV 30 sec” trigger enables the XW Auto Generator Start to
start the generator whenever the battery voltage reaches or drops below a
pre-set voltage for longer than 30 seconds.
The XW Auto Generator Start will stop the generator when the stop
trigger is provided (“Stop V”, “Stop Absorb”, or “Stop Float”).
Dependencies The “Start DCV 30 sec” trigger requires the XW Auto Generator Start to
be in Automatic mode and needs the “Stop Absorb” or “Stop Float”
trigger be enabled or a parameter to be set for the “Stop V” trigger.
Considerations If the voltage trigger is set too high, the generator will start more
frequently than is convenient.
If the voltage trigger is set too low, the batteries may be damaged by
repeated cycles of excessive discharge. The generator running time
necessary to charge the batteries may exceed “Max Run Time” and use
too much fuel in the process.
If using the XW Inverter/Charger Low Batt Cut Out voltage setting to
trigger a start-on-voltage setting on the XW Auto Generator Start, be sure
to set the XW Auto Generator Start voltage trigger higher than the XW
Inverter/Charger Low Batt Cut out voltage. Otherwise the inverter output
turns off and then back on when the generator auto-starts.
If using an automatic generator starting system with the start trigger set to
the same voltage as the LBCO voltage, do not set the LBCO Delay for
less than the amount of time it takes the generator to start and connect.
Otherwise, inverter output turns off and then back on when the generator
auto-starts.
Battery Voltage
Information Battery voltage can be monitored from the System screen or the inverter/
charger menu.
If “Stop Float” or “Stop Absorb” has been enabled, the generator will stop
when the Float or Absorption stages of the battery charging have begun.
If the “Stop V” is used, the generator will stop when the battery voltage
reaches the parameter set in this trigger, regardless of whether the
batteries are charged.
Values Default
Disabled, 4.0 V to 65.0 V(increments of 0.1 V) 44.0 V
