Sena 010303 - Additional Features and Protection; Protection and Memory Functions

8
Stage 6- CV (Constant Voltage): The battery is charged to nearly full, and will top o󰀨 at 14.6V
DC;
Stage 7 - Resting: The charger will cut o󰀨 with full charged statement, and achieves the high
energy e󰀩ciency;
Stage 8-Recond: When it is fully charged and low to 12.8V within 2min, the charger will judge
automatically.
Stage 9 - Restoring: The charger monitors a fully charged battery automatically. If the battery
falls below 12.8V DC, the charger will restart from stage 4 to stage 7.
ADDITIONAL FEATURES
a. REVERSE POLARITY PROTECTION
The REVERSE POLARITY INDICATOR LED will light and the power will not be sent to out-
put 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 TROUBLE-
SHOOTING ERROR CODES.
c. OVER-VOLTAGE PROTECTION
When the charger is set to charge in a di󰀨erent voltage than the detected voltage of the
battery, this protection will be engaged. Refer to Error Code of “Er1” in the section of TRO-
UBLESHOOTING ERROR CODES.
d. BATTERY DIAGNOTICS 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 e󰀨ects 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 o󰀨 if overhe-
ating 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 rst 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.
