C) Winter / : The recommended charging program for cold weather conditions
(ambient temperature of -10°C to +5°C) for normal lead acid batteries (wet batteries)
Press the “Mode” button -> switch from the 12V AGM to the “Winter” charging program.
Note:
When the charger is disconnected from the socket outlet, the last charging program to
have been set will be saved (apart from RECOND and SUPPLY) and will be the default
program the next time the charger is used.
F Restoration of the charging capability of discharged lead acid batteries with higher
charging voltage. Not for AGM and GEL batteries!
K Charge status of the battery in percent (1 increment = 25%) and charging process
(increment lit = the battery has reached the charge level shown; increment in the
battery symbol ashes = the battery is being charged to the next charge level; all
increments are lit = the battery is fully charged).
G Clamps are wrongly connected (reverse polarity) or there is a short-circuit.
5.2 Setting the charging programs (Fig. 2)
If there is a short - circuit between the charging terminals while the SUPPLY function is
on, the message “Lo V” will appear in the LCD display.
E Charging voltage in volts, faulty battery (BAt) / fully charged (FUL) / connected with
reverse polarity or short-circuit at the clamps (Err) / short-circuit at the clamps in
SUPPLY operating mode (LoV).
D Charging a 12V battery (lead acid battery, AGM battery and GEL battery) in charge
maintenance mode.
H Power supply, e.g. when changing a battery.
Press the “Mode” button (Fig. 1/Item 1) to switch to the various programs. The symbol
for the applicable program will appear in the display. The batteries will be charged
using the program which is displayed.
5.2.1 Standard charging programs
If the voltage of the battery is less than 3.5 V or more than 15 V, the battery is either not
suitable for charging or it is faulty. The message “BAt” will appear in the LCD display.
A) 12V STD: Charging program for lead acid batteries (wet, EFB batteries). When the
charger is used for the rst time, 12V STD will appear in the display.
B) 12V AGM: Charging program for AGM batteries Press the “Mode” button -> switch
from the 12V STD to the 12V AGM charging program.
5.2.2 Special charging programs
D) 12V M: Charging program for batteries with a low capacity (see “Technical data”) and
for trickle charging of all batteries listed in 3. “Proper use”. Press the “Mode” button ->
switch from the “Winter” to the “12 M” charging program.
