Battery Charger Troubleshooting
To determine the cause of a charger error condition, refer to the troubleshooting
solutions below to resolve the situation.
Problem Possible Cause Solution
AC1/AC2 LED is on,
but will not start
charging (allow 40
seconds to
synchronize).
1) Charger is disabled on the Setup
menu.
2) Charger Block is enabled and the
Conext XW+ is inside of the charger
block time window.
3) The Conext XW+ is load shaving.
4) Charger is set for 2-stage charging
and has completed a full charge
cycle.
5) Battery voltage is below 40 V and
AC source could not be qualified.
6) Gen support is enabled and the
draw from the loads exceeds the Gen
support amps setting.
1) Enable the charger.
2) Disable Charger Block if you need
to override this feature.
3) Check the load shave settings. If the
load draw from the grid exceeds
Load Shave Amps, the charger will not
operate.
4) No action required. The charger
comes on when the battery reaches
the ReCharge Volts setting.
Otherwise use the Force Chg setting
on the device setup menu to force a
bulk or float charge.
5) Recharge the batteries with an
external battery charger or replace the
batteries.
6) Temporarily disable Gen support
mode, or reduce loads below Gen
Support Amps setting.
