If charger's out voltage is under 60V, it is
abnormal.
Please refer to the error sheet.
When the charging voltage is indicated as
normal condition (63V), convert automatic
/ manual switch to automatic and start
charging.

EPROM fail
Over voltage - Refer to page 7-73
Over current - Refer to page 7-72, 74.
Battery error (After starting charging, the voltage doesn't go over 52V for 2 hours.)
Check the battery.
Transformer over heat (Stop charging when it is over 160
Á
C).
If input voltage is high, output current is over normal value and there is heat in the
trans because of SCR control part fault.
Check the output current and PCB control board
Heatsink over heat (Stop charging when it is over 100
Á
C).
Check the cooling fan, SCR connection cable contact point and control part.
Power supply error (input power 220/380V wrong wiring). - Refer to page 7-71.
Power supply error (absent phase) - Check if input cable is open.
AC fail (black out) - Check if input voltage is right.
Low current (If this sign is on for setting value (60 sec), charging is over).
Manual stop.
