The MCU must be powered with 230V / 50 or 60 Hz on the interlock input in order to drive the motor. This signal is a confirmation that the door is closed and locked. MCU receives its commands to rotate the drum from the CPU via a serial communication link between the MCU and CPU.
  • Page 144 Troubleshooting 21:5 MOTOR SHORT CIRCIUT This error code is generated by the MCU for drum motor. The MCU reads the power consumption of the motor continuously. If the current for some reason exceeds a predetermined limit, the MCU will cut the current to the motor. After the motor has stopped (= tachometer indicates stationary motor), the MCU will attempt to restart it.
  • Page 145 Troubleshooting 21:7 LOW DC VOLTAGE This error code is generated by the MCU for drum motor. The MCU constantly measures the voltage over the mains input. If the voltage is below a predefined limit, the MCU will shut off the current to the motor.
