Wear hand protection
Hands and arms must be protected when
working with batteries as there may be
contact with battery acid.
For indoor use only
Due to its design (protection class), this
device may be used in dry indoor areas only.
Protection class I
This is a class I appliance (protective
conductor)
Connect to electrical circuits with
adequate fuse protection only
The current required by the appliance can be
very high (see Technical Data). The electrical
circuit the device is connected to must have
adequate fuse protection.
Protection class IP40
This device is protected against ingress of
solid particles (D > 1 mm). It is not protected
against ingress of liquids in any manner.
ABOUT THE CHARGER
This charger can be used to charge all standard
12 V lead-acid batteries (wet-cell and start/stop
batteries). It must not be used to charge lithium
batteries. The charger is suitable for use with
batteries with capacities from 30 Ah to 500 Ah and
can be used without time limitation for charging and
float charging.
CHARGING GRAPH
The charging graph shows voltage (U) over time (t)
and current (I) over time (t). It applies to charging
operations carried out at an exterior temperature of
25°C. (see fig. A, page 3):
Initial analysis: battery status is analysed
Bulk charge: up to 14.4 V at 25°C and 32 A
Full charge: on reaching 14.4 V at 25°, charging
current decreases to 2 A
Post-charge analysis: checks whether battery
voltage falls below 12 V
10
Float charge: 13.6 V, maximum charging current
32 A, decreasing to 1 A
Float at 13.6 V, maximum charging current 32 A
Restart: charging cycle restarted
INITIAL ANALYSIS
The charger checks whether the battery is correctly
connected. The battery's charge level (V) and total
capacity (Ah) are measured to determine the correct
charging profile. Charge status is shown on the LED
display (see table, page 2).
BULK CHARGE AND FULL CHARGE
The charger begins to charge the battery at a
constant current to 14.4 V (at 25°C). The charging
voltage is then kept at a constant 14.4 V while
the charge current is reduced until it falls below a
defined value. The charging voltage then falls to
13.6 V before the float charge phase begins. During
charging, charging status is shown by the number
of LEDs illuminated. The flashing segment above the
LEDs shows that charging is in progress. When the
battery is fully charged, all 5 LED segments remain
illuminated constantly. If measured battery voltage is
below 2.0 V, the charger will enter error mode and
the warning triangle above the battery indicator will
start to flash.
POST-CHARGE ANALYSIS
When the charging phase is complete, the charger
analyses the battery again. If the charger finds a
fault in the battery, the warning triangle will begin
to flash. Short circuits in individual cells can be
detected during the post-charge analysis. This is not
possible during initial analysis. If the battery voltage
falls below 12 V within two minutes, the charger
will enter fault mode and the red warning triangle
will begin to flash. The charging operation will be
interrupted.
FLOAT CHARGE
When the battery is fully charged, the charger will
deliver a charge of 13.6 V at 25°C and a voltage
of up to 32 A. All LEDs will pulsate to indicate this.
