AC input wiring from utility / generator is connected to
AC output terminals instead of AC Input Terminals and
hence, creating back-feed condition
Unit will not boot / switch ON. LCD displays: “Wiring Error”
Low DC input voltage due to weak/bad battery:
No DC input voltage due to blowing of external DC fuse
as a result of overload or reverse polarity (AC input is
available).
CAUTIon! Reverse polarity is likely to cause
permanent damage and is not covered by warranty.
DC input voltage is < 5v for the 12v version or < 10v for the 24v version due to (i) Bad
battery and (ii) Blowing of external DC input fuse due to overload or reverse polarity.
•
LCD displays: “Bad Battery”
•
Unit will not switch off with the On / Off Key. Disconnect AC and DC input
connections. Fully charge the battery by external charger or replace with a new,
fully charged battery. Reconnect the AC and DC input connections and restart.
DC input voltage is < 9v for the 12v version or < 18v for the 24v version
•
LCD displays “Battery Weak”
•
CAUTIon!
Do not switch off the unit with the ON / OFF Key. Disconnect AC and
DC input connections. Fully charge the battery by external charger or replace with
new, fully charged battery. Reconnect the AC and DC input connections and restart.
Limit distortion of generator AC output waveform due to
overload by interrupting charging if generator frequency
is not within the range of 45 to 65 Hz.
•
Display screens “Battery Charging” (SCREEN 4, page 52) and “Charging Mode”
(SCREEN 6, page 52) will show message “Inp Hz Abnormal”
•
Display screen showing Internal (Int) and External (Ext) charging Amps
(SCREEN 5, page 52) will display 0 A against Internal (Int) Amps
•
Charging is resumed once the frequency of the generator is within the
window of 45 Hz to 65 Hz.
