LiFePO4 Batteries:
Installation:
The
thermal contact
of sensor and
inside temperature
of the battery
should be well
. Thus, it should be
screwed down to the
negative pole
of the battery, because in most of the cases, this is the cooler side (the positive pole is
often biased by the exhaust heat of internal fuses of the battery, electronic systems for cell equalization, balancers etc.)
Function:
In case of abnormal battery temperatures, such as < -20 °C, > 50 °C, the charging voltage will be reduced strongly
to the
safety charging voltage
of approx. 12.80 V for battery protection, and the maximum charging current rate will be
halved (safety mode, LED
"Charge" is flashing
). Any charging data being recorded hitherto will be kept in memory. Battery
charging is then interrupted, but the supply of consumers being possibly connected will be continued by the charger until
the battery temperature is again within the acceptable range. After that, automatic charging will be resumed.
In case of temperatures
below 0 °C
,
the charging current will be reduced considerably for battery protection
, the LED
"Charge"
will turn off every 2 seconds, and longer charging times can be expected. Also refer to "
Charging Program 4
for
"
LiFePO4
Batteries, Charging Voltage Rates and Temperature Control",
page 9
.
Warning: If the charging program LiFePO4 had been set, the temperature sensor must be connected for
reasons of battery safety. Otherwise, the unit will not operate, and the LEDs
"Batt.
Full
" and "
Charge
" are
flashing simultaneously!
"Display"
6-pole plug-type connector for
remote control
:
Connection (plug and play) of a remote display/remote control is possible for convenient remote control, if the charging
converter had been installed in a difficult to access location.
Both units are equipped with a power "limit" function allowing to reduce the charging capacity temporarily at the touch of
a button (see technical data).
LED Remote Control S
Order No. 2076
7 LEDs for convenient control of functions and charging state.
LCD Charge Control S-VCC
Order No. 1248
With illuminated, excellently readable display showing the state of the charging converter, the current charging
phase, the voltage of board and STARTER battery and the instantaneous charging current.
Pilot Lamps:
"Batt. Full"
(BOARD battery fully charged,
green
)**:
If it is on:
Battery has been charged to 100 %, trickle charge U2, finished.
If it is flashing:
Main charging process is effected in the charging phase U1, indication of the charging state of
75 % (lead), approx. 90 % (LiFePO4) (short flashing), gradual increase to 100 % (long flashing).
Off:
Main charging process is still being executed in the phase I.
"Charge"
(Main charging BOARD battery,
yellow
)**:
If it is on:
Charging converter operates, the BOARD battery is controlled and charged.
If it is flashing:
Battery Protection: Battery overtemperature > 50 °C, switchover to low safety charging
voltage and half of the max. charging current. Automatic return, as soon as the temperature
is 2 °C less.
If it turns off shortly
every 2 s:
1. The power control of the charging converter has reduced the output capacity by more
than 30 % (STARTER battery discharge protection), since the voltage of the STARTER
battery dropped below the adjusted value for "Reduction of the charging capacity". The
charging capacity will be increased automatically, as soon as the voltage exceeds the value
"increase of the charging capacity".
2. Only LiFePO4: Battery temperature below 0 °C. The charging current can be reduced for
battery protection for all modes of charging. If the battery is discharged, longer charging
times.
Off:
Charging converter in idle mode.
** "Batt. Full"
and
"Charge"
are flashing alternately:
The battery temperature sensor is not connected with charging program LiFePO4!
