ADDITIONAL FEATURES
a. REVERSE POLARITY PROTECTION
The REVERSE POLARITY INDICATOR LED will light and the power will not be sent to output cables if a reverse connection is
detected.
b. SHORT CIRCUIT PROTECTION
This protection is triggered if the charger detects less than 0.5V across the clamps, and no power will be sent to output cables.
Refer to Error Code of "Er1" in the section of TROUBLESHOOTING ERROR CODES.
c. OVER-VOLTAGE PROTECTION
When the charger is set to charge in a different voltage than the detected voltage of the battery, this protection will be engaged.
Refer to Error Code of "Er1" in the section of TROUBLESHOOTING ERROR CODES.
d. BATTERY DIAGNOSTICS FUNCTION
The charger continuously monitors battery condition and may report certain charging failures as fault codes. Refer to Error Code
of "Er1" and "Er2" in the section of TROUBLESHOOTING ERROR CODES. Conditions that cause the errors include: if the battery
voltage does not rise appropriately 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 could become sulphated and unable to accept a charge. Reconditioning Function may help
reverse the effects of sulphation and restore a batteries ability to accept a charge. If the charger detects a sulphated battery,
it will automatically activate Battery Reconditioning Function. If successful, normal recharging will resume after the battery is
desulphated. If unsuccessful at desulphating the battery, refer to Error Code of "Er2" in the section of TROUBLESHOOTING ERROR
CODES.
f. OVERHEAT PROTECTION
The charger is designed to decrease the charging current and even shut itself off if overheating is detected. Once the charger cools
down, it will resume charging automatically. Refer to Error Code of "Er3" in the section of TROUBLESHOOTING ERROR CODES.
g. MODE-SETTING MEMORY FUNCTION
The microprocessor inside the charger has mode-setting memory function, which means the charger can directly enter into the
mode the users set last time. This function can erase the users' worry about forgetting the setting for their owner batteries and
shorten the setting time for the users' convenience.
The housing of the charger is water resistant (IP 65). The first digit – "6" means protection of humans against the access to
dangerous parts by means of a wire – dust-proof protection.
The second digit "5" means the protection against the stream of water (12,5 l/min) poured on the housing from any direction. IP
65 apply to housing only, not clamps and AC power lead.
