User manual GRAUPNER ULTRAMAT 5

[. . . ] The charger must always be used with the original connecting leads. The charge outputs and connecting leads must not be modified, extended or connected to each other in any way. 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. [. . . ] -Batteries installed in a device, or which are electrically connected to other components. the charger develops considerable heat in use. 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. Check before charging: are all connections in good condition?Please bear in mind that fast-charging NC packs can be hazardous. 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. simply eliminate the problem and press the START button. 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. The following types are suitable: Order No. Be sure to use the correct size and type of connector. 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. Always set them up on a non-inflammable, heat-resistant surface. The orange monitor lamp (NiCd) will now light up to show that the charger is ready for use. [. . . ] 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. This diode must be by-passed if the charger is to work correctly. Please consult the instructions supplied with your transmitter for details of how to do this. We recommend that you remove the battery from the transmitter to avoid the possibility of damage due to overheating. [. . . ]
