Additional charger:
Fully automatic battery charger (CAC) MT 1240 with “IUoU” Lithium charging characteristic and intelligent charging
control with dynamic charging time calculation and temperature compensation of the charging current at temperatures
below 0°C and also above 50°C. Maximum charging power even with mains undervoltage.
Remote control/Display panel:
The display panel is located on the device in the storage box of your vehicle.
Operating indicators:
•
“Current” (charging current, red):
◦
Lights up brighter or darker depending on the charging current emitted.
•
“Batt. I” (on-board batteries, yellow):
◦
Lights up: On-board batteries are monitored and charged.
◦
Flashes: Battery protection: Abnormal battery temperature >50°C (depending on type), Switchover to
low safety charging voltage and half max. Charging current, automatic return when the batteries cool
down slightly.
◦
Goes out briefly every 2 s: Only for LiFePo: Battery temperature below 0°C, the charging current can
be reduced to protect the battery for all types of charging, longer charging times for discharged batteries
◦
Off: Charging output is blocked (safety switch)
•
“Battery full” (on-board batteries fully charged, green):
◦
Lights up: On-board batteries 100% charged, charge retention U2, finished.
◦
Flashes: The main charging process is in the U1 charging phase, charge status display of approx. 80%
(short flashing) gradually increasing to 100% (long flashing).
◦
Off: The main charging process is still in the I-phase.
•
“Main charging” (On-board batteries main charge, yellow):
◦
Lights up: The main charging process works in the I phase and then in the U1 charging phase.
◦
Flashes: 1. Battery temperature sensor is not connected for LiFePo charging characteristics! 2. External
overvoltage battery I or II, > 15.5 V delay 20 s, automatic reset < 12.8 V (depending on type),
delay 30 s.
◦
Off: Charge retention U2, or storage charge U3
•
“Batt. I” (On-board batteries II, yellow): (Note: This 2nd charging outlet is not used!)
◦
Lights up: On-board batteries are monitored and charged.
◦
Flashes: Battery protection: Abnormal Battery II temperature > 50°C (depending on type), Switchover to
low safety charging voltage and half max. Charging current, automatic return when the batteries cool down
slightly.
◦
Goes out briefly every 2 s: Only for LiFePo: Battery temperature below 0°C, the charging current can
be reduced to protect the battery for all types of charging, longer charging times for discharged
batteries
◦
Off: Charging output is blocked (safety switch)
•
“Power” (mains, green):
◦
Lights up: Mains present and charger ready.
◦
Flashes: 1. Safety timer shutdown, charging I-phase took too long, too many consumers, battery
defective (cell closure). Reset only by power switch (rear of device) in position “0”)
2. Internal device fault (overheating), automatic reset after cooling.
3. Battery reverse polarity (+ and - interchanged).
Note:
The secondary battery III (starter battery) is operated with reduced voltage and current together with the main
battery “I” (master) and does not have its own display on the device. The function of the output can be recognised by
the rise of the voltage on the battery to be charged .
Night reduction “Silent Mode”:
The Silent Mode function can be activated at the push of a button (1 second display on/off button) especially
for sleeping at night:
•
the internal cooling fan is constantly set to the lowest noise, even speed
•
all display LEDs are switched off, only the current display „Current“ lights up weakly,
•
the lower cooling capacity may reduce the charging capacity somewhat depending on the ambient
temperature of the charger
Reactivating the display and thus always the full charging capacity:
•
Manually possible at any time by pressing the button again (1 second)
•
Automatically after 10 hours by built-in timer (end of night‘s sleep)
No further operation or maintenance of the device is required.
