stationary), the MCU checks to see whether the input voltage is still low. If it is, this error code is shown. The reason
for this error code being activated can be low mains voltage or that the machine’s on/off switch has been operated in
an unsuitable manner.
Further information can be obtained by studying the contents of

MCU ERROR LOG 1

and

MCU ERROR LOG 2

:

•

UNDERVOLTAGE 2

(specifies how many times this error code has been active).

•

UNDERVOLTAGE 1

(specifies how many times the voltage has dropped below the limit. The difference between

undervoltage 1 and undervoltage 2 indicates how many times there has been an undervoltage 1 without it being
confirmed when the motor has stopped).

•

LAST FAULT CODE N/8

(shows the 8 latest error codes) Undervoltages can be registered even during normal op-

eration. Consequently, a small number of registrations need not mean that there is an error in the MCU.

Recommended actions:

1. Check that the supply voltage is stable and never drops below nominal voltage - 10%.
2. Check the fuses and cables.
3. Check the supply voltage in the network cabling and at the MCU in the machine.

21:8 HIGH 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 exceeds a predefined limit, the MCU
will shut off the current to the motor. Once the motor has stopped (= the tacho sensor indicates that the motor is sta-
tionary), the MCU checks to see whether the input voltage is still high. If it is, this error code is shown.
Recommended actions:

1. Check incoming AC voltage.

21:12 NO PARAMET. SET IN MCU

This error code is generated by the MCU for drum motor.
The MCU contains several different parameter sets for different motors. During power up the control system checks
that the correct parameter set digit is written into the MCU. If not, the control system will write down the parameter
set digit defined in fixed configuration.
If the MCU discovers that no parameter set value is written down into the MCU, the error code will be shown.
Possible causes:
This can be caused by wrong software in CPU or wrong MCU for the current machine.
Recommended actions:

1. Make sure correct machine software and correct MCU are used.

21:13 UNBALANCE

This error code is generated by the MCU for drum motor.
The MCU monitors the unbalance switch status. If the status is active already at program start, this error code is
shown.

21:15 MOTOR NOT FOLLOW

This error code is generated by the MCU. The MCU must always receive information on the rotation of the motor from
the tacho sensor in order to rotate. If the tacho sensor is not working, the motor can rotate for max. 10 seconds during
the starting process. After this period, this error code will be activated.
Possible causes:

• Break in the cables between the tacho sensor and the MCU.
• Break in connectors in tacho cables.
• Break in one of the phases to the motor (cables or connectors). This error can be suspected if the motor does not

rotate for 10 seconds (the motor will not start with only two phases).

• Error in tacho generator.
• Error in tacho circuits in the MCU.
Further information can be obtained by studying the contents of

MCU ERROR LOG 1

and

MCU ERROR LOG 2

. Study the

following:

•

MOTOR NOT FOLLOW

(specifies how many times this error code has occurred).
