Charging Steps
STEP 1: DIAGNOSIS (Check if battery has connected with the charger and also check battery voltage)
STEP 2: DESULPHATION (If battery voltage is too low, programs automatically generate pulsing current to remove sulphate, up to 10 minutes)
STEP 3: ANALYSE (Check if the battery voltage reaches to the threshold after desulphation, and charging begins if the battery voltage is OK)
STEP 4: SOFT START (Charge with echelon constant current)
STEP 5: BULK (Charge with constant maximum current until battery voltage is reached to the threshold)
STEP 6: ABSORPTION (Provide gradually declining current charge for maximum battery voltage)
STEP 7: ANALYSE (Test if the battery can hold charge)
STEP 8: MAINTENANCE (Continuously monitor the battery, and charging current will intelligently adapt to the variable battery voltage)

CAUSE
The charger is overheated
1) Open-circuit
2) Dirty Battery Posts
3) Dead Battery
4) Output Short Circuit
Charging in 12 V Mode(s) for 24 V battery
Battery cannot store energy or cannot be
recovered through Repair Mode
Reverse Polarity
Overload in SUPPLY Mode
(will automatically shut down
for 30 seconds as protection)

SOLUTION
The charging will automatically pause. Do NOT cut off the
power supply, and the charger will work again when cooled
down.
1) Connect the red and black clamps to the battery posts
2) Clean the battery posts
3) Replace the battery with a new one immediately
4) Disconnect red and black output terminals
Restart the charger and choose the correct charge mode.
1) Replace the battery with a new one
2) If REPAIR Mode has not be tried, try it for recovery
Exchange the red and black clamps to
the correct battery posts
Disconnect the external device
