    MultiCharger 1500 getting damaged. The MultiCharger 1500 is designed as a bench unit, which is cooled by the free flow of air from the base to the top. You should therefore make sure that your MultiCharger 1500 remains uncovered.

  • Page 9: Connections

    Mains power is connected to the MultiCharger 1500 through a plug for non-heating devices. 3 potential-free relay contacts, which signal various states of the MultiCharger 1500, and also a hardware contact "Remote On/Off", can be connected through a 15-pole SUB-D socket.

  • Page 10: 15-Pole Sub-D Socket

    1.2.3 USB interface A Mini-USB socket is fitted on the right front side of the MultiCharger 1500, which can be used to connect a laptop or PC. The MultiCharger 1500 can be configured through this interface and software updates can be carried out.

  • Page 11: Displays And Operating Controls

    1.3.1 Button 1 (On/Off) Button 1 is used to switch the MultiCharger 1500 on and off. If the connected mains power voltage is over 90V, pressing button 1 switches the MultiCharger 1500 on and makes it ready for use. You will also need to use button 1 to re-enable the system if a fault makes the unit shut down.

    1.3.7 LC Display The MultiCharger 1500’s LCD has two lines and can show 16 characters per line. The current output voltage and current output are displayed on the top line. The bottom line acts as a status display, showing in plain text the operating state and details of any faults that occur (see Appendix A).

  • Page 13: Operating Modes

    Setting operating mode You can only set the operating mode if the MultiCharger 1500 is ready for use, i.e. if it has been switched on via button 1 (On/Off). However, the unit does not have to be charging a battery and no battery needs to be connected to the charger output.

  • Page 14: Output Current In Battery Charging Mode

    For example, if the rated current is exceeded for 30 seconds, the MultiCharger 1500 current limit is held at the level of the rated current for 2 minutes 30 seconds. After that time, the rated current can again be exceeded.

  • Page 15: External Power Supply (Eps) Mode

    Connecting a battery (with a voltage of >1V) to the MultiCharger 1500 before the output voltage is switched on is not allowed. If this is done, a ‘Return voltage’ error message will appear. The output voltage on the MultiCharger 1500 can then not be switched on until the battery is once again removed.

    MultiCharger 1500 maximum charging current (100A for 12V batteries) being too high for some types of battery. Should this be the case, the MultiCharger 1500 output current limit should therefore be set lower (see section 5.6). For the maximum permitted charging current, refer to the technical specifications of the relevant motorcycle battery.

  • Page 17: Internal Monitoring

    These are individually described in the following sub-sections. Mains power monitoring If the mains voltage drops below 85V, the MultiCharger 1500 signals a fault and switches off. The message ‘Mains error’ appears on the LCD display. If the mains voltage rises above 90V, the MultiCharger 1500 can be made ready for use by pressing button 1 (On/Off).

  • Page 18: Temperature Monitoring

    This monitoring function measures the temperature inside the MultiCharger 1500. If this rises above the maximum limit of 90°C, the MultiCharger 1500 signals a fault and is switched off, but not locked. The message ‘Temperature err.’ appears on the LCD display and the red LED comes on.

  • Page 19: External Monitoring

    Short circuit The MultiCharger 1500 can tell that it has an output short circuit if this occurs in the current limiter and output voltage drops below the set lower limit (default setting 7V or 14V respectively). In this case, the MultiCharger 1500 signals a fault and switches itself off to the locked position. The message ‘Short circuit’...

  • Page 20: Reverse Polarity Return Voltage

    This monitoring function is only active in EPS mode (see section 2.3). You are not permitted to connect a battery to the MultiCharger 1500 in this operating mode. If you do nevertheless connect a battery before trying to start charging, and connect it the wrong way round, the MultiCharger 1500 signals a fault.

    Inappropriate changes can detrimentally impact the way the charger works. None of the settings can be changed unless the MultiCharger 1500 is ready for use, i.e. unless it has been switched on via button 1 (On/Off). However, the unit should not be charging a battery and no battery should to be connected.
