User manual GRAUPNER ULTRAMAT 5

[. . . ] The charge and power cables must not be coiled up when the charger is in use. check the charger at regular intervals for damage to cables , connectors , case etc. Avoid short-circuits between the power lead plug, the charge socket and the car bodywork, as the unit is not protected against these situations. [. . . ] -Batteries installed in a device, or which are electrically connected to other components. The aluminium fins on the case are designed to cool the unit, and must not be covered or obstructed in any way. Set up the unit with space all round it so that heat can dissipate freely. Allow the unit to cool down for a generous period after a rapid charge process. The unit is designed for charging the following battery types: The number before the letter states the number of cells, which in turn indicates the battery voltage (single cell 1. Error displays The charger features several functions which inform and warn you of particular problems. Power supply problem (car battery) Reverse polarity Poor contact Safety timer triggered Charger fault = lamp off = lamp flashes NiCd battery red red red green red NiMH battery red red red red green red Problem Car battery flat Reverse polarity at battery Intermittent battery contact Charge time exceeded Charger may overheated Do not attempt to rapid-charge any battery unless it is expressly stated to be suitable for the high currents which this charger produces. Please remember that new packs do not reach their full capacity until they have undergone several charge / discharge cycles, and the charge process may also be terminated prematurely with new batteries. We recommend that you carry out several test charges until you are confident that the automatic termination circuit works correctly, and that the unit charges your battery fully. Be sure to maintain correct polarity: red = positive terminal (OUT +), black = negative terminal (OUT -). If the connector on the charge adaptor does not match the one on the battery to be charged, you can easily make your own adaptor from any Graupner charge lead by cutting it down to a length of no more than 80 cm. Before you connect the charger to a cigar lighter socket check carefully that the socket is wired with the correct polarity, and can supply currents of up to 8 A. You will find this information in the instruction manual supplied with your car. To avoid damage, never place the charger and the pack to be charged directly on the car seat or other part of the car. The orange monitor lamp (NiCd) will now light up to show that the charger is ready for use. Every time you press the button the monitor lamp switches to the other battery type. The corresponding monitor lamp now switches colour from orange to green to confirm that it has detected the presence of the battery. As soon as the battery is fully charged, the rapid charge process is interrupted, the monitor lamp flashes green, and a brief audible alarm signal sounds. [. . . ] To prevent excessive charge currents the charge lead must be at least 80 cm long. Most RC system transmitters are equipped with a protective diode which prevents damage to the circuitry if the charge lead should be shorted or reversed. Please consult the instructions supplied with your transmitter for details of how to do this. [. . . ]
