When using the charging unit in schools and hobby- workshops the usage of power
supplies and charging units has to be controlled by responsible teachers or skilled
personell.
If covers are opened or parts are removed, except it is possible manually, voltage-
carrying components can lay open. Terminals can also carry voltage. If it is neces-
sary to open the unit before adjustment, maintenance, repairing or exchange of parts
or modules, the charging unit has to be separated from all voltage sources. Repairing
or maintenance of the charging unit may only be executed by SKILLED PERONELL
who know the dangers and the respective rules.
Condensers in the unit can still carry voltage even if the unit has been separated from
all voltage sources.
Don’t use the charging unit immediately after bringing it from a cold into a warm
room. Condensed water might impair or destroy your unit. Give the charger time to
warm up to room temperature without switching it on.

1. Introduction
Accumulators consists of two electrodes which are in an electrolyte; so an accumu-
lator is a chemical element. Inside this element chemical processes are active. As
these processes are reversible accumulators can be recharged.
This accu charger is constructed to charge and discharge up to four nickel-cadmium
and/or nickel-metal-hydride accumulators. The nickel-cadmium accumulators have
a positive electrode made from nickelhydroxide and a negative electrode from meta-
lic cadmium. The electrolyte consists of kaliumhydroxide. Nickel-metal-hydride
accumulators have a positive nickel- electrode and a negative hydride accumulating
electrode. The electrolyt is potash lye.
To charge up an accumulator the so called charging voltage is necessary which is
higher than the cell voltage. During charge more charge (mAh) has to be added as
you can take from it. This relation of added and taken charge is called efficiency.
The discharging capacity which is strongly dependent on the discharging current is
decisive for the condition of the accumulator. The voltage added cannot be used as
criterion because a part of it is lost (e.g. is converted into heat).
The capacity which is printed on the accumulator is the maximum charging capacity
which an accumulator is able to give off. This means an accumulator with a capacity
of 400 mAh can theoretically give off e.g. for one hour a current of 400 mA (= 0,4
Ampere). These values depend strongly on many factors (such as condition of the
accumulator, discharging current, temperature etc.).
At charging units the name C- rate is used very often. The C- rate is the current value
which is normally stated for charge and discharge. This current in Ampere corre-
sponds to the nominal capacity in Amperehours; this means for an accumulator with
400 mAh that 1C = 0.4 A.
Note that the discharge capacity of an accumulator strongly depends on the
discharge current: the lower the discharge current the greater the dischargeable
capacity. At automatic mode the discharge current is adapted automatically to the
condition of the accumulator. At manual mode discharge is C/3 at average.
Respectable manufacturers state the capacity of an accumulator at C/3. That means
e.g. that an accumulator with 1200 mAh will reach this 1200 mAh at a discharge cur-
rent of 400 mA (= C/3). If a discharge current of C/10 (= 120 mA) is stated you can be
sure that this accumulator doesn’t reach 1200 mAh at a discharge current of 400 mA.
Because of this the accumulator stated with C/10 is not so good as the C/3 one.
If accumulators are stored over a longer period of time they loose charge. This effect
is called self- discharge.

3. Features
This is a charging unit for nickel-cadmium and nickel-metal-hydride accumulators of
size mono (UM1/D), baby (UM2/C), mignon (UM3/AA), micro (UM4/AAA) and lady
(UM5/N). Up to four different accumulators can be charged at the same time.
The accumulators may only be inserted into the unit. Without any settings batteries
are charged with automatic mode.
Charging is controlled by a microcomputer and charges up the accumulator to
100%. 100% means 115% of the stated capacity in case of new accumulators and
below 100% of the stated capacity in case of older accumulators.
It is possible that the discharge capacity don’t reach 100%. However, this discharge
value must be higher than 80%. If he is smaller the accumulator is faulty (test with
ALIVE- program).
No overcharging is possible, therefore the longest life for the accumulators can be
reached.
Predischarge is not necessary before charging. The accumulator is charged to the
present possible 100%.
Charge and discharge cycle is independent of the charging state and the temperatu-
re of the accumulator.
The charge and discharge current is microcomputer controlled.
At automatic mode the stated capacity is insignificant for this charging unit. Only at
manual mode range of capacity has to be selected, which meets the accumulator.
The charging unit has an automatic accumulator- control (charging voltage and char-
ging quantity).
This unit has an automatic fan control. The two fans are getting started at charge and
discharge. At stand- by every 30 minits both fans are running for about 5 minits, too.
The automatic accumulator identification immediately recognizes when an accumu-
lator is connected or disconnected, even if the accumulator is fully discharged. At
automatic mode a refresh program will be startet to rebuild these full discharged
accumulators.
Self- discharge of the accumulator is prevented by trickle charge.

It is not allowed to connect power supplies and charging units to persons or animals.
When operating the unit pay attention to sufficient ventilation. Never cover the venti-
lating slots. Never place the unit on tableclothes or on carpets! Place the unit on a
hard and flame resistant base. Make sure good ventilation of the unit is possible.
Cooling of the unit is mainly achieved by two fans which are running during charge
and discharge and at stand-by every 30 minits for a short time too.
Attention:
If any accumulator inserted is charged or discharged easy to
recognize by the flowing current „I“ both fans must run. Running
fans are audible quite good. If these fans are not running switch
off immediately and secure against unintentional use!
Respectable manufacturers recommend an ambient temperature of 20°C when ope-
rating a charger. Avoid direct sunlight.
Do not operate charging units without supervision.
For work under voltage only approved tools may be used.
If there are doubts whether a safe usage is still possible the charging unit has to be
put out of operation and secured against unintentional use.
It must be supposed that a safe usage is no longer possible
- if the charging unit shows visible damage
- if the station does not work
- after longterm storage under unfavourable conditions
- after transport stress.
A damaged power cord may only be replaced by skilled peronell.
Use the unit only in dry and closed rooms.
The unit may only operate within an ambient temperature of 0°C to 40°C.
Pay attention to right polarity when inserting accumulators.
The unit is protected against short circuit.

Charging mode:
• AUTOMATIC (AUTO): current at charge and discharge is set automatically. Value
of current is adapted automatically to the condition of the accumulator.
• MANUAL (MAN): charge and discharge current are set indirectly by the selected
range of capacity.
Voltages (U):
Voltage of battery is measured when no current flows (therefore it can’t be controlled
during work). If no voltage is shown voltage was not measured until that time.
Charge condition:
To see at first sight approximate charge condition of a battery a symbol is displayed.
This symbol is only to recognize progress of charging or discharging within a short
time. At charge this symbol is filled from the buttom to the top and at discharge it is
made empty from the top to the buttom. This is no sign how much time does it take
until end of program. If condition of accumulator was not measured a symbol with a
horizontal line is shown (at this instruction manual symbol is represented by the let-
ter „S“).
Current of charge/discharge:
At charge and discharge the running current I is displayed. Note that amperage is set
automatically at automatic mode. If the current has not been measured at begin or
after finishing program (READY/ERROR) no current flows and I= ——A will appear.
Time:
Complete time in hours and minits (hh:mm) of treating the accumulator is shown.
Therefore at program Check, Cycle and Alive you see the whole added time of char-
ging and discharging. Only time for Trickle won’t be added.
Charging time for accumulators up to 2000 mAh reaches from 90 minits up to 4
hours at automatic mode and will take about 90 minits at manual mode. For accu-
mulators with 6000 mAh charge will take up to 8 hours at automatic mode and up to
4 hours at manual mode. The real charging times can differ as the accumulator defi-
nes it by himself.
8
No memory effect is possible (as charge and discharge currents are pulsed). A high
internal resistance of the accumulator decreases and the current load capacity
increases.
The efficiency of the accumulator is increased (relation of necessary charging quan-
tity and capacity which can be taken out).
Only one function key is needed to choose settings and to show data of the accu-
mulators.
The calculated charging and discharging capacities of the connected accumulators
are stored. These data can be recalled at any time and are stored until the accumu-
lator is removed.
The charging unit has a memory backup. During power failure data of accumulators
and programs are stored up to 24 hours. If the charging unit regains power these
programs continue. To guarantee this feature the unit has to be switched on for 2
hours.
The liquid crystal display (alphanumerical LCD) is used to display
• all charging programs (charge, discharge, check, cycle, alive)
• all charging modes (AUTOMATIC / MANUAL)
• all actual voltages (U)
• all charge conditions of batteries (battery symbol)
• all actual currents of charge/discharge (I)
• all needed times in hours and minits (hh:mm)
• all actual/stored accumulator data in mAh (C / D)
Charging programs:
- CHARGE = charging only one time
- DISCHARGE = discharging only one time
- CHECK = discharge and charge
- CYCLE = charge- discharge- charge
- ALIVE = charge- discharge- charge- discharge- charge
The ALIVE program is to refresh new accumulators and those stored over a long
period of time.
Please be aware that accumulators which have been treated badly can take up only
30% of their capacity at the beginning. This bad efficiency can be recognized by a
high charging capacity (C) and a very small discharging capacity (D). Charge those
accumulators with the ALIVE program. After some cycles discharge capacity (D)
increases.
