Table 5-1: Troubleshooting
Display never comes on
•
Ensure that the input power cable is connected firmly to the unit
and to a functioning power source at the correct voltage.
•
If both connections and the power supply are good, make sure
the input circuit breaker has not tripped.
Output voltage never rises
above zero while charging
•
Check the connections between the unit and the load, making
sure that the connection is solid and that the polarity is correct.
•
Check the output voltage with a separate voltage meter; if voltage
is present, the internal circuitry may need service. Consult
Bonitron for service options.
Display shows no output
current while charging
•
Check the output connections to make sure there is good contact.
•
Make sure there is voltage at the output terminals.
Load capacitor takes a long
time to charge/discharge
•
Check the connections between the unit and the load, making
sure that the connection is solid and that the polarity is correct.
•
Large loads may take a long time to charge or discharge (such as
a load in excess of 1 Farad).
•
Excessively leaky loads may not be able to reach the full 800V
range.
•
Make sure the charging current is not set to a very low value.
SEE WARNING BELOW!
Red voltage present light is
ON
•
The voltage present light indicates that there is voltage between
the output terminals of the unit. If the display indicates that no
voltage is present, contact Bonitron.
Red voltage present light
never turns on regardless of
output voltage
•
Check the output voltage with a separate voltmeter. If the voltage
is above 50VDC, your unit may require service. Contact Bonitron.
DANGER!
Always monitor the output voltage while operating the unit. Ensure that the
attached loads do not exceed their rated voltage, as catastrophic damage,
injury, or death may occur.
