Danger due to
acid, gases and
vapours

Working with battery chargers poses a number of dangers, such as:

Electrical hazard due to grid and charging current

-

Hazardous electromagnetic fields that may pose a risk of death for individu-

-

als with pacemakers.

An electric shock can be fatal. Every electric shock poses a risk of death. To pre­vent electric shock during operation:

Do not touch any voltage-carrying parts inside or outside of the device.

-

Never touch the battery poles.

-

Do not short-circuit the charging cable or charging terminals.

-

All cables and leads must be secured, undamaged, insulated, and adequately di­mensioned. Loose connections, scorched, damaged, or under-dimensioned
cables and leads must be repaired immediately by an authorized specialist.

Batteries contain acids which pose a risk to the eyes and skin. Furthermore, char­ging batteries produces gases and vapors that may be hazardous to your health
and are highly explosive under certain circumstances.

Only use battery chargers in well ventilated rooms in order to prevent the accu­mulation of explosive gases. Battery charging rooms are not considered at risk of
explosion if a hydrogen concentration of less than 4 % is guaranteed by natural or
artificial ventilation.

During charging, observe a minimum distance of 0.5 m (19.69 in.) between the
battery and battery charger. Keep potential sources of ignition such as fire and
open flames away from the battery.

Never disconnect the battery (e.g., charging terminals) during charging.

Never breathe in the gases and vapors produced by the battery – ensure there is
a sufficient supply of fresh air.

Do not place any tools or electrically conductive metals on the battery, in order
to prevent short circuits.

Never allow battery acid to come into contact with your eyes, skin, or clothing.
Wear eye protection and appropriate protective clothing. Rinse away any
splashed acid immediately and thoroughly with clean water, and consult a physi­cian if necessary.

General informa­tion on working
with batteries

Protect batteries from dirt and mechanical damage.

-

Store charged batteries in cool rooms. The lowest self discharge occurs at

-

approx. +2°C (35.6°F).
Refer to the specifications of the battery manufacturer or conduct weekly

-

visual inspections to ensure that the battery is filled with acid (electrolyte)
up to the maximum marking.
Do not start operating the device, or immediately stop operation, and have

-

the battery inspected by an authorized specialist if:

The acid level is uneven or there is high water consumption in individual

-

cells caused by a possible defect

-

EN

Personal protec­tion and protec­tion of others

Safety measures
in normal opera­tion

Keep persons, especially children, away from the device and working area during
operation. However, if persons are in the vicinity:

Inform them of any dangers (hazardous acids and gases, risk due to grid and

-

charging current, etc.),
Provide suitable protective equipment.

-

Before leaving the working area, ensure that no personal injury or property dam­age can occur in your absence.

Operate devices with ground conductors only on a grid with a ground conductor
and a socket with a ground conductor contact. Operating the device on a grid
without a ground conductor or on a socket without a ground conductor contact is
considered gross negligence. The manufacturer accepts no liability for any dam­age resulting from improper use.

Only operate the device in accordance with the protection class shown on the
rating plate.

Never commission the device if it is damaged.

Have the grid and device supply lead regularly inspected by an electrician to en­sure that the ground conductor is functioning properly.

Safety devices that are not fully functional and components with defects must
be repaired by an authorized specialist before the device is turned on.

EMC measures In certain cases, even though a device complies with the standard limit values for

emissions, it may affect the application area for which it was designed (e.g. when
there is sensitive equipment at the same location, or if the site where the device
is installed is close to either radio or television receivers).
If this is the case, then the operating company is obliged to take appropriate ac­tion to rectify the situation.

Data protection The user is responsible for the safekeeping of any changes made to the factory

settings. The manufacturer accepts no liability for any deleted personal settings.

Maintenance Before each start-up, check the mains plug and mains cable and charging cables

and charging terminals for damage.
If dirt accumulates on the device, clean the surface of the device housing with a
soft cloth and only with solvent-free cleaning agents.

"Configuration mode" section.

A list appears with the following selection options:

The individual selection options are explained in greater detail below:

Electrolyte circulation ("Air pump") - for 3 kW (C1) devices only:

The electrolyte circulation cycle is controlled by the battery charger's control
system. A number of selection options are available for this purpose.

More information on the electrolyte
circulation can be found under
"Electrolyte circulation 3 kW (C1)" in
the "Options" chapter.

The following settings are available for electrolyte circulation:

Off:

-

Electrolyte circulation switched off

-

Continuous operation ("continuous"):

-

Electrolyte circulation permanently on

-

-

Automatic adjustment of electrolyte circulation flow rate based on the

-

set battery parameters

"User" - "On"/"Off":

-

Individual setting of the electrolyte circulation

-

The settings for "On" and "Off" determine the pulse/pause ratio of the

-

air flow intervals

Default electrolyte circulation programs and their relevant parameters can be
found in the table below:

Program ON 1 OFF 1 Repeat ON 2 OFF 2

1 30 min 25 min 1 x 5 min 25 min

2 3 min 10 min 4 x 3 min 20 min

3 3 min 12 min 1 x 3 min 12 min

36

4 5 min 10 min 3 x 5 min 20 min

5 2.5 min 7.5 min 1 x 2.5 min 7.5 min

In each of these programs, the solenoid valve opens for a time "ON 1" and closes
for a time "OFF 1". This process is repeated for the number of times specified
under "Repeat". After this number of repetitions has been completed, the pro­cess continues with the "ON 2" and "OFF 2" times until charging is completed.

Temperature-controlled charging:

The following settings are available for temperature-controlled charging:

automatic/OFF/required:

-

automatic ... Temperature-dependent adjustment of the charging char-

-

acteristic
OFF ... The measured battery temperature is not taken into account

-

required ...

-

Charging only starts when a temperature sensor is connected

Error overtemperature ON/OFF:

-

ON ... Error message in the event of battery overtemperature

-

Charging process stops and can only be continued once the battery has
cooled down and been reconnected
OFF ... No error message in the event of battery overtemperature

-

-

EN

Equalising charge:

OFF:

-

There is no equalising charge.
Delay:

-

If the battery remains connected to the battery charger for the duration of
the equalising charge delay ("equalize charge delay"), then a special type of
charging takes place. This prevents acid stratification.
The parameters for the current (ampere / 100 ampere hours), voltage (volt /
cell) and duration of the equalising charge can be changed.
Weekday:

-

Specify the weekday on which the equalising charge is to take place.
The parameters for the current (ampere / 100 ampere hours), voltage (volt /
cell) and duration of the equalising charge can be changed.
Manual equalising charge ("Manual"):

-

An equalising charge can be started manually by pressing the relevant key on
the display. The equalising charge starts after a set delay time has been ob­served. The charge parameters that have been set are followed. The para­meters for the current (ampere / 100 ampere hours), voltage (volt / cell) and
duration of the equalising charge may all be changed. This function is only
available for Pb-Wet characteristics.

If a setting for the equalising charge is enabled, a symbol on the home screen
next to the set ampere hours or charging time shows whether an equalising
charge is being carried out or can be started.

37

Delay:

charge start delay:
Delay time (minutes) of actual start of charging relative to the moment when
charge start was initiated

charge end delay:
Delay time (minutes) before charge end is signalled (e.g. green indicator) relative
to the moment when charging actually stopped

at mains failure restart charging:
If this option is selected, the charging process is restarted automatically as soon
as the electrical grid becomes available again after a disruption to the electrical
grid.

Calendar:

The calendar function allows charging to be started automatically according to
the following criteria:

Time window in which charging may not be started if a battery is connected

-

Time window in which charging is to be started using a defined characteristic

-

Symbol for characteristic 2:

-

Time window in which charging is
to be started using characteristic 2
(e.g. 20:00-24:00)

Please note:

Ongoing charging operations are not affected by the set time windows.
If in the example above a battery is connected at 5:45, the charge end time is
governed by the requirements of the battery and is not interrupted by the end
time specified for the set time window (6:00 in the example).

EN

If the battery is connected during the "stop" time window, charging is started
automatically during the next time window.

Options

Safety The housing has to be partially opened to connect the options.

WARNING!

Danger of electric shock.

This may result in serious injuries or death.

The housing must never be opened by anyone other than a service technician

▶

trained by the manufacturer.
Before working with the housing open, the device must be disconnected from

▶

the grid.
A suitable measuring device must be used to ensure that electrically charged

▶

components (e.g., capacitors) are completely discharged.
With the aid of a clearly legible, understandable warning sign, ensure that

▶

the device remains disconnected from the grid until all work has been com­pleted.

WARNING!

Danger due to work that is not carried out properly.

This can result in severe personal injury and damage to property.

All work involved with connecting optional components must only be carried

▶

out by service technicians trained by the manufacturer.
If there are Installation Instructions or User Information for the optional

▶

component concerned, then all warning notices and instructions therein
must be obeyed.
For all options with electrical connections, a safety inspection must be car-

▶

ried out in accordance with the applicable national and international stand­ards and guidelines after connection work has been carried out.
You can obtain more information about the safety inspection from the au-

▶

thorized service body.
The service body will provide the necessary documents upon request.

Electrolyte cir­culation 3 kW
(C1)

52

NOTE!

Danger due to the ingress of electrolyte from the battery or due to operation
without any back pressure.

This may result in damage to the air pump.

Always set up the charger at least 0.5 m (1 ft. 7.69 in.) above the battery to

▶

be charged.
Always use an undamaged connecting hose provided specifically for this pur-

▶

pose to connect the charger's compressed air outlet to the battery.

NOTE!

Danger due to non-observance of the permissible mains voltage tolerance.

This can cause malfunctions and damage.

For the electrolyte circulation option, a restricted mains voltage tolerance

▶

vis-à-vis the charger of +/-10 V applies.

The electrolyte circulation option introduces air into the battery through capil­lary tubes that are provided specifically for this purpose. This allows intensive

mixing of the electrolyte to take place. The benefit is reduced heating of the bat­tery, and consequently longer battery-life, plus reduced water loss during char­ging.

If a pump fault or leaks in the connection with the battery result in a fault being
detected, then the status code "Statecode 14" will appear on the display. One
way in which this fault can be indicated is by using an external indicator lamp to
show a common error.

Weight of the electrolyte circulation set:
Air-Puls + air hose kit

3 kW (C1) 2.5 kg (5.51 lb)

Electrolyte circulation air filter insert

The air filter insert for the integrated air pump should be cleaned once a year. In
dusty environments, the cleaning interval should be shortened accordingly. The
air filter insert must be removed for cleaning. Remove the air filter by levering it
out with a slotted screwdriver; then refit it as follows.

NOTE!

Danger from using the air filter with unsuitable chargers.

This can result in damage to property.

Only use the air filter with the chargers provided by the manufacturer for

▶

this purpose.

External start/
stop

The external start/stop option prevents spark formation at the charging plug if it
is disconnected during charging. Special contacts inside the charging plug re­gister a disconnection. These contacts are leading in comparison to the main
contacts. An immediate charging stop is triggered. There is therefore no wear on
the main contacts and the level of safety against oxyhydrogen ignition is in­creased.

Temperature­controlled char­ging

The temperature-controlled charging option always adjusts the charging voltage
according to the current temperature of the battery. This results in considerably
longer battery-life, especially where batteries are used in cold stores.

LED strip The LED strip acts as a status indicator and lights up in the same colours as the

display elements on the control panel. An LED strip including a diffuser is in­stalled in the gap between the front wall and upper part of the housing.

Air filter In dusty environments, the air filter prevents the inside of the device from be-

coming dirty. This avoids a possible reduction in power and other problems. De-
