2-7. SAFETY TIMER
- If charging is not finished within charging time, this Safety Timer should stop
charging.
- When charge current is changed, the Safety Timer is also automatically changed.
Safety Timer per battery type is gained based on Linear charge mode
NiCd, NiMH = (Selected capacity * 60 / Selected current) * 1.5
LiIo, LiPo, LiFe, Pb = (Selected capacity * 60 / Selected current) * 2.0
Safety Timer should be "OFF" if the safety timer is bigger than 900minutes.
- Expected time can vary depending on input power or AC power (internal) in
CONFIG SETUP.
(Refer to the file " watt limit & safe timer.xls" )
2-8. FLAT CHECK
- "END : FLAT CHECK " : This message should be shown when the battery voltage
is not changed for a specific time during charging.
- Also, when a battery which has BIG capacity is being charged with smaller charge
current, this message could be also shown.
f. e. 4800mAh 0.1A Charge
- You can turn on or off for this FLAT CHECK function.
2-9. REPEAK CYCLE
- This is to recharge battery pack which is charged.
- This mode should be activated when it moves to "REPEAK" mode from CHARGE
PROCESS
- Since this function is to charge again the fully charged battery, this PEAK DELAY
should be automatically set to "0". ( PEAK DELAY setting value is not charged )
- Set wanted repeak charge cycle number.
2-10. REPEAK DELAY
- Set the delay time between first repeak and second repeak.
2-11. CHG-VOLTAGE
- This is only for lithium battery.
- Setting charging voltage can be used as battery storage.
Normally, LiPo battery is charged to 4.2V/cell, for the battery storage, it can
be charged to 3.7V/cell with CV charging.
- For charging range per battery type, please refer to "Setup Range sheet" and
battery instruction. Normal max. charging voltage settings are for:
LiFe: 3.6V/cell, LiIo: 4.1V/cell, LiMn = LiPo: 4.2V/cell. For higher cycle life
time, use 0.1V less. For storage use 0.4-0.5V less.
