ULTRAMAT

8. Using the charger for the first time

When the ULTRAMAT 14 is initially connected to a 12 V car battery or a 230 V mains socket, the

unit runs through the information routine which provides the user with a brief summary of the

essential user settings. The charger’s screen displays the following information in sequence:

The ULTRAMAT 14’s name appears on the screen.

After about two seconds the ULTRAMAT 14 switches to the Ni-Cd /

Ni-MH charge program. There the charge current and Delta Peak

point can be adjusted.

2 sec.

9. Ni-Cd / Ni-MH program

When set to the Ni-Cd / Ni-MH charge program the ULTRAMAT 14

can charge 1 - 14 cells. While the charge current indicator in the

top line is flashing, you can use the INC / DEC buttons as a conve-

nient means of setting the maximum charge current. The range of

adjustment is 0.1 - 5 A in increments of 0.1 A.

Press the ENTER button to confirm that the setting is correct; the

bottom line of the display now starts flashing. At this point you can

adjust the Delta Peak cut-off sensitivity in increments of 0.1 mV,

again using the INC / DEC buttons. The adjustment range is 3 mV

to 25 mV per cell.

A value of 15 mV has proved to be a useful basic setting, but ple-

ase refer to the information provided by the battery manufacturer if

you are unsure of this.

When you have entered these two settings you can connect a bat-

tery pack consisting of 1 - 14 Ni-Cd / Ni-MH cells to the charger.

You will hear an audible signal to confirm proper contact (unless

you have disabled the buzzer), and the screen display will start

flashing.

You can now initiate the charge process by pressing the ENTER

button.

The unit adjusts the charge current at intervals until the set charge

current is reached. During this time the screen displays the mes-

sage „CHG Max.“ in the top line, alternating with the momentary

charge current. As soon as the set charge current is reached, the

top line of the screen alternates between „CHG“ and „Ni“.

Please note that the maximum charge current varies according to

the number of cells in the pack on charge. If you wish to charge a

fairly large battery and set a charge current of, say, 5.0 A, the

ULTRAMAT 10 will never reach this value. In this case the mes-

sage „CHG Max.“ will be superimposed during the whole charge

process.

Press the INC or DEC button to change to a display of charge

time and charge capacity.

Press either of the two buttons a second time to revert to the pre-

vious display.

6. Charge programs

The various facilities of the charger are divided up into two program groups which you can select

by pressing the ENTER button. The sequence is shown in the flow chart below.

Note: If a battery is connected to the charger, it is not possible to switch to a different program

group. This is an intentional safety feature, designed to make it impossible to switch accidentally to

a charge program which is unsuitable for the battery you are using when a charge process is ac

tually in progress. You can interrupt the charge process at any time by pressing the „MODE“ but-

ton.

Ni-Cd / Ni-MH battery programs: for charging 1 - 14 cells, charge current variable within the range

0.1 - 5 A in 0.1 A increments; Delta Peak sensitivity variable within the range 3 - 25 mV in 1 mV in-

crements; variable „Safety Timer“, range 5 - 300 minutes in 5-minute increments; switchable buz.

zer.

Li-Po / Li-Ion battery programs: for charging 1 - 5 cells, charge capacity 100 - 9900 mAh, variab-

le in 100 mAh increments, variable „Safety Timer“, range 5 - 300 minutes in 5-minute increments;

switchable buzzer.
