‘Udc-ripple’
Volt Ripple Exceeds
‘ ’: blink
Voltage ripple on the DC input ex-
ceeds 1.25Vrms
Check the battery cables and termi-
nals.
Check the battery capacity; in-
crease it if necessary.
Udc-ripple
Volt Ripple Exceeds
The INVERTER of “Combi-Gamma”
cuts out as a result of excessive
voltage ripple on the DC input
Install batteries with a higher capac-
ity.
Use shorter and/or thicker battery
cables and reset the Combi-Gamma
(Power OFF and ON again).
‘Udc-OV’
Battery over voltage.
‘ ’: blink
Battery charger is not in normal
charging status to cause battery
voltage too high.
Replace the “Combi-Gamma”.
Udc-OV
Battery over voltage.
Incorrect battery voltage connection
(12V system but connected to 24V
battery)
Recheck if the Combi-Gamma and
the battery voltage is matched.
‘Idc-OC’
Over current.
‘ ’: blink
The actual charge current is 1.5
times larger than the set current
value (D1-08) when AC CHARGER
is operating.
Stop the Charge mode of the
“Combi-Gamma”.
Idc-OC
Over current.
Repair or replace the
“Combi-Gamma”.
‘Bat-NG’
Battery Fault
‘ ’: blink
The charging time of AC CHARGER
has been over 10 hours and re-
mains in Bulk Charge mode.
Replace the battery banks.
Bat-NG
Battery Fault
(D1-09=1) shows the battery is at
fault.
