Automatic computer charger
MP 24 / MP 24 DUO
Operating instructions
The MP 24 computer charger is a micro-processor controlled
unit designed for recharging NC batteries. The MP 24 DUO can
also charge NC receiver battery packs (4 or 5 NC cells).
A 16 character LCD panel keeps you informed of the charge
current, charge period, battery voltage and final charged volta-
ge. At the end of the process the final voltage and charge period
are stored for as long as the unit is left connected to the car
battery. The display also warns you of reversed polarity or
insufficient car battery voltage.
The MP 24 DUO also features two LEDs which indicate the
charge status of the receiver battery.
Different audible signals are provided to indicate start, battery
full, reversed polarity and car battery discharged.
The charge current is infinitely variable within the range 0.4 A
to 3 A by means of a potentiometer. The charger automatically
detects the number of NC cells connected to it.
Diode protected or deeply discharged batteries can also be
charged by means of the "Unterspannung" (low voltage) but-
ton.
The MP 24 DUO provides a constant 400 mA current for
recharging receiver batteries.
All terminals are fitted with reverse polarity protection systems.
The unit is protected against overheating (as a result of direct
sunshine, charging too many cells etc.) by monitor circuits
which guard against excess current and temperature.

Charging 4 to 24 cells at 0.4 to 3 A
MP 24 and MP 24 DUO
1. Connect the charger to a 12 V car battery.
Check that both clips are making good contact.
RED = POSITIVE (+)
BLACK = NEGATIVE (-)
When the 12 V car battery is connected you will see the
message READY in the display.
2. Rotate the current adjustor knob fully anti-clockwise (minimum
charge current).
3. Connect the NC battery to the output sockets on the right hand
side of the front panel of the charger.
RED = POSITIVE (+)
BLACK = NEGATIVE (-)
The voltage of the NC pack should now appear in the display,
together with the word "START", indicating that the MP 24 is
ready to charge the NC battery.
If the word "READY" is still visible, the NC pack is either
discharged too deeply or protected against reverse polarity by
a built-in diode (sometimes used in transmitters). If you now
hold down the button "Unterspannung" (low voltage) you can
start the charging procedure with the "START" button as
described in step 4.
4. Start the charge process.
a. If the battery voltage appears in the display:
Start the charge process by pressing the "START" button
briefly. You can then set the charge current to the correct value
(4.c).
b. If the display still shows "READY":
Press and hold the "Unterspannung" (low voltage) button,
then start the charge process by pressing the "START" button
briefly.
c. Be sure to set a charge current which is suitable for the battery
connected to the unit. Refer to the battery manufacturer's
information if you are not sure.
For MULTIPLEX batteries we recommend 2 x C as a starting
point, i.e. battery capacity in Ah x 2 = charge current in A.
The voltage indicated when the "Unterspannung" (low voltage)
button is pressed does not refer to the actual voltage of the NC
pack. When you release the "START" and "Unterspannung"
buttons the voltage of the NC pack is increased by the forward
voltage of the diode; it is this value which appears in the display.
Charging 4- or 5-cell
NiCd receiver batteries at 400 mA
MP 24 DUO only !
1. Connect the charger to a 12 V car battery.
Check that both clips are making good contact.
RED = POSITIVE (+)
BLACK = NEGATIVE (-)
When the 12 V car battery is connected you will see the
message "READY" in the display.
2. Connect the receiver battery to the output sockets on the left
hand side of the front panel of the charger. This will automati-
cally start the charging process.
RED = POSITIVE (+)
BLACK = NEGATIVE (-)
The red LED marked "Laden" (charge) should now light up and
a series of audible beeps indicates that the charging process
has started.
3. When the battery is fully charged a series of beeps sounds and
the green LED "Fertig" (complete) lights up. You can now
disconnect the battery from the charger.
Do not touch any bare contacts or connections.
This unit is designed specifically for use with a 12V
DC battery (car battery). Do not connect it to any
other power source.
Dangerous voltages can be present at the output
sockets when NiCd batteries are faulty.
Always use insulated plugs.
