No Panel Indicators Lit
Check incoming voltage.
If no voltage, check input fuses within the charger.
If the incoming fuses are blown, contact Bonitron for assistance
before replacing fuses. This can be an indication of further damage
to the charger.
Check 24V power supply at TB3-1 and TB3-3. If there is no
voltage, contact Bonitron for further assistance.
Fuses blow at power up
Check for proper size & type fuses.
Make sure the voltage differential between the output of the
charger and the battery bank is below 50V before connecting the
charger to the storage bank.
Ensure charger is isolated from the drive system. Failure to use an
isolation transformer can cause a return path through the charger
that can produce high currents.
If problem persists, contact Bonitron.
Charger does not charge
Check panel indicators. If the Power indicator is not on, go to top
symptom.
Make sure th
e “Enable” input is activated. The “Charge” indicator
must be on.
If the “Charge” indicator is on, repeat the startup procedure to
check the voltage setpoint and current limits. If the unit is enabled
and the “Current Limit” indicator is on, the current limit may be set
too low.
Storage Bank will not fully charge
Check the input voltage, and verify that it is at least 50V higher than
the desired charge voltage.
If the “Charge” indicator is on, repeat the startup procedure to
check the voltage setpoint and current limits. If the unit is enabled
and the “Current Limit” indicator is on, the current limit may be set
too low.
Overtemp condition
This indicates that the charger is above 150°F (65°C).
Make sure the fan is operating and airflow is unrestricted.
Make sure the ambient temperature is below 100°F (40°C).
Cannot Bulk Charge / Equalize
battery bank
Make sure the Charge and Enable inputs are both active.
If the Charging and Equalize indicators are both on, make sure the
input voltage to the charger is at least 50V higher than the Equalize
Voltage.
Verify the Equalize voltage is correct.
Bulk Charge / Equalize stays on
after removing command
Ensure equalize mode jumper is in the correct position.
Bulk Charge / Equalize will not stay
on after removing command
Ensure equalize mode jumper is in the correct position.
