PROTECTION FUNCTIONS

Over current protection	Yes
AC Input under voltage protection	When AC voltage <85Vac@120Vac or <150Vac@220Vac, the charger will switch off
Output short circuit protection	Yes, will automatic resume after short is removed
Battery reversed protection	yes
No-load protection	yes
Over temperature	The charger must be able to operate up to 45℃ and will de-rate the charge current linearly to 50% when reaching 60℃. When the case reaching >65℃ the charger is allowed to stop, when the temperature falls, the charger automatically resumes. No defects at high temperatures
Temperature compensation	For the lead-acid charger the NTC is used for temperature compensation at -4mV/⁰C per 2V cell; the length of NTC cable is 1 meter For the Lithium charger the external temperature sensor is used to prevent charging < 0 ℃ ambient temperature
Fan cooling	The Fan rotates at charging and stops after fully charged
Fully charged automatic disconnect	Only for Lithium version by internal relay
Fault LED indication	Yes, see chapter LED indicators

SAFETY AND ENVIRONMENT

Safety test AC to DC	≤20mA@2000Vac/1min
Safety test AC to CASE	≤20mA@2000Vac/1min
Safety test DC to CASE	≤20mA@1000Vac/1min
Insulation Resistance test	AC to CASE > 100MΩ/DC 500V
Working ambient temperature	-20 …+45⁰C ; 45…60⁰C linear de-rating to 50%

LED INDICATORS

LED Indication Label	For LI Battery	For LA Battery
Battery Capacity Status	In Charging：Red light flashes Fully Charged：Green light is glowing	Red LED flash per second, to show capacity < 80% Yellow LED flash per second, to show capacity> 80% Green LED flash per second, to show capacity = 100%
Non Load Status	R,G,R,G,R,G
Fault Status( “-“: means pause)	Over-volt/current protection: flash R, G, R, -, -, - Ambient temperature too high or low: flash R,G,R,G, -, - Over temperature: flash G,R,-,-,-,- Output under-voltage: flash R,G,-,-,-,- Input AC voltage abnormal: flash R,G,R,G,R,- Other faults: flash G,R,G,-,-,-

COMMON FAULT AND SOLUTIONS

LED Indication Status ( “-“: means pause)	Fault Indication	Solution
R,G,R,G,R,G	Non Load connection	Check the connection between charger and battery, whether B+,B- polarity reversed, whether battery voltage lower than start voltage
R, G, R, -, -, -	Over Voltage/Current	If restart the charger still can’t fix, the charger failed, return to repair
R,G,R,G, -, -	Environmental Temp over-heat or too low	Check whether temperature around the charger too high, whether the FAN rotate normally, whether the heat emission slots under the FAN cover blocked, whether environment ventilation isn’t good, check the temperature sensor probe…etc
G,R,-,-,-,-	Charger over-heat	Check the temperature as upon
R,G,-,-,-,-	Output under-voltage	If restart the charger still can’t fix, the charger failed, return to repair
R,G,R,G,R,-	Input AC voltage abnormal	Check Input AC voltage need charger spec, also check AC plug connection
G,R,G,-,-,-	When one of upon 5 faults repeat 5 times, the LED shows status	Unplug the AC power and re-power on the charger, to see which fault item match, fix it accordingly.
