Corrective Action
1. Ensure that the battery voltage is
correct and the cable connections are
secure; ensure that the battery is in
good condition.
1. Contact an authorized Toro distributor.
1. Possible causes include poor battery
health, very deeply discharged battery,
poorly connected battery, and/or
high parasitic loads on battery while
charging. Possible solutions: Replace
batteries. Check DC connections.
Disconnect parasitic loads. This error
will clear once the charger is reset by
cycling DC.
1. The battery is connected to the charger
incorrectly. Ensure that the battery
connections are secure.
1. Connect charger to an AC source that
provides stable AC between 85 - 270
VAC / 45-65 Hz.
1. The charger failed to turn on properly.
Disconnect the AC input and battery
connection for 30 seconds before
retrying.
1. The AC source is unstable. Could
be caused by undersized generator
or severely undersized input cables.
Connect charger to an AC source that
provides stable AC between 85 - 270
VAC / 45-65 Hz.
1. Software upgrade failure or script
operation failure. Ensure that the new
software is correct.
1. Ensure that the connection of the
signal wires to the battery is secure.
1. Ensure that the connection of the
signal wires to the battery is secure.
Corrective Action
1. Remove the AC connection and
battery connection for a minimum of
30 seconds and retry. If it fails again,
please contact an authorized Toro
distributor.
