Using The Charger For The Fi Rst Time; Nixx Charging Program - GRAUPNER ULTRA TWIN 40 Bedienungsanleitung

Connect the charger's 100 - 240 V AC input to a mains wall socket, or connect the charger's DC input to a 12 V car battery or an 11 ... 15 V DC mains
PSU with a capacity of at least 10 A.
WARNING: Never connect both inputs at the same time!

The ULTRA TWIN 40 is ready for use, both outputs are in NiXX mode. Each of the two charge outputs features a separate screen, operating controls and
sockets, and can be operated independently of the other. This means that you can set different battery types, cell counts and / or charge currents. The
charger is controlled using just three operating buttons.
Button Description
TYPE/AMP Select battery type / charging current
DATA Select data display
START Starts / stops the charging progress
Now you must set the type of battery to be charged, and the charge current. For NiXX batteries please see sequential diagram 12; for LiXX batteries see
diagram 13.
WARNING: The following types of battery must not be connected to the charger:
- Faulty or damaged cells or batteries.
- Non-rechargeable batteries (dry cells). Caution: explosion hazard!
- Batteries which are not expressly stated by the manufacturer to be suitable for the currents which this unit delivers during the charge process.
- Packs which are already fully charged or hot, or only partially discharged.
NiXX-Delta-Peak (- Peak) trigger voltage
The automatic charge termination circuit (battery full detection) works on the proven Delta Peak principle (also known as the
Delta-V process), which is already in use in millions of chargers. This process analyses the voltage peak of the charge curve,
which indicates with great accuracy when the maximum charge capacity is reached. When the charge process is started the
battery voltage initially rises continuously, but as the pack approaches full capacity it begins to heat up. This in turn causes the
battery voltage to fall slightly (Delta-V). The charger detects and assesses the voltage decline. The cut-off voltage for NiMH
batteries is fi xed at 5 mV per cell.
