24VDC PRO-Verter 5000-120 AGS Operator Manual
PRO-Verter Charger Problems: Solutions and Explanations
Unit won’t transfer to Charge mode when connected to generator or grid AC
Solution:
Is the charge (CHG) LED on the user interface blinking? If not, the charger does not
recognize the incoming AC as being within acceptable limits. Disconnect the AC input cable from
the PRO-Verter. Measure the voltage at the cable terminals—it should be 120 VAC +/- 20 VAC). If
the CHG LED is blinking, the transfer relay should close within 20 seconds and begin charging. If the
LED is on solid, the relay should be closed and the charger should begin charging.
Charger not charging even though Charger LED is on steady
Solution:
Check the METER 01A DC Volts and METER 01B DC Amps meter values on the LCD
screen. It should be close to the maximum rated (or programmed) charge current if the battery
voltage is under 28.8 VDC on 24-volt models. Check the Meter SETUP 03A AC Input Amps setting
and ensure that it is set in accordance with system requirements.
Charge amps are lower than expected, or is 0 amps DC
Solution:
The charge rate may have been reduced to keep the input voltage above 80 VAC
.
Also,
check the 03A AC Input Amps and SETUP 03E Max Charge Rate settings to determine if the current
is being limited.
Charger output voltage is different than expected
Solution:
Check the Battery Temperature Sensor (BTS) temperature. The charge voltage settings
will increase if the temperature around the BTS is below 77 °F (25 °C) or decrease if the temperature
around the BTS is higher than 77 °F (25 °C). The BTS is located inside of the PRO-Verter.
