a reduction in battery capacity. The charger will then charge at a higher voltage to recover the
battery's capacity.
Stage 9 — Restoring: Automatic on-off monitoring. The charger monitors a fully charged
battery. If the battery falls below 12.8V DC, the charger will restart and enter stage one
charging again.
ADDITIONAL FEATURES
a. Reverse Polarity Protection
The REVERSE POLARITY INDICATOR LED will light and the charger will cut out if a
reverse connection is detected.
b. Short Circuit Protection
If the charger detects less than 0.5V across the clamps it will cut out and display the
error code "Er1". Please see TROUBLESHOOTING ERROR CODES.
c. Over-voltage Protection
If the charger is set to charge at a different voltage than the detected voltage of the
battery, 'Over-Voltage Protection' will be engaged. The error code "Er1" will be displayed.
Please see TROUBLESHOOTING ERROR CODES.
d. Battery Diagnostics Function
The charger continuously monitors the battery's condition and may report certain
charging failures as fault codes.The error codes "Er1" or "Er2" will be displayed.
Please see TROUBLESHOOTING ERROR CODES.
Errors occur if: the battery voltage does not rise as expected during the charging process
(indicating a shorted cell) or if the maximum charge time has been exceeded, etc.
e. Battery Reconditioning Function
If a battery is discharged deeply, it may be sulphated and unable to accept a charge.
The reconditioning function may help restore a battery's ability to accept a charge.
The charger will automatically diagnose this situation and if successful normal
recharging will resume, after the battery has been de-sulphated. If unsuccessful at
de-sulphating the battery error code "Er2" will be displayed. Please see
TROUBLESHOOTING ERROR CODES.
f. Overheat Protection
If it overheats the charger is designed to decrease the charging current or even shut
itself off. Once the charger cools down, it will resume charging automatically. Error code
"Er3" will be displayed. Please see TROUBLESHOOTING ERROR CODES.
g. Mode-setting Memory Function
With its mode-setting memory function the charger can enter the mode that it was last
set to. This function can reduce the worry about forgetting battery settings and reduce
set up time.
