    1. Remarks • Caution: • Before working at the machine make sure that the batteries are disconnected (disconnect battery plug); except for cases of current and voltage measurements. • When replacing the stripe fuses only loosen the screws. Do not remove them completely to avoid short-circuit hazard.

  • Page 52: Signal Measuring At The Drive Control Unit

    9.1 Signal Measuring at the Drive Control Unit Check the following items when testing the drive control unit. If the respective signals • do not apply, the drive control unit does not work sufficiently. In the circuit diagram the drive control unit is designated with A4. When testing the drive control unit, be supported by the circuit diagram and check the connections there since the complete procedure became more complex by releasing via A1, closing the drive rheostat switch, the direction switch and the K4 relay.
  • Page 53 9.1 Signal Measuring at the Drive Control Unit 1 Self test 1. Self-test Before the drive control unit is operable, it executes a self-test. This self-test starts automatically after switching on the machine with key switch. If, during this self-test, the drive control unit detects an error, the LED on the unit flashes to signal non-operability The machine will then not start riding flashes to signal non operability.
  • Page 54 9.1 Signal Measuring at the Drive Control Unit 2 Drive direction 2. Drive direction The drive direction is set via the direction selector switch S7 but closing of this switch alone is not sufficient for signalling the selection to the drive control unit. Simultaneous releasing of A1, closing of the drive rheostat switch S8 and the K4 relay switching contact is required.
  • Page 55 9.1 Signal Measuring at the Drive Control Unit Drive potentiometer switch S8: This switch is located at the accelerator and is closed after pedal actuation. Then it h i l t d t th d ft the battery plus signal is transferred to the coil of the K4 relay and the relay closes the switching contact.

    9.2 Settings at the Accelerator Pedal Setting the drive potentiometer switch S8 and the drive potentiometer ‘R1‘ at the • Accelerator pedal is required. Caution: Before proceeding to settings at the drive control unit make sure that the drive wheel t th d i th t th d i rotates freely and has no contact with the ground.
  • Page 60 9.2 Settings at the Accelerator Pedal The ‘S8’ drive potentiometer switch has to be set such that it is not activated in neutral pedal position, i.e. a small gap between the actuation roller of the switch and the eccentric disk of the accelerator is required. If the accelerator pedal is pressed down, the switch should be actuated ( li ki (clicking sound) but without bending the actuation lever.
