:

The last 10 disconnections due to errors resulting in code 

 can be read on the mixer display:

• 

Press the emergency stop

• 

Press 

 and 

 to browse the log

• 

The diodes on the speed indicator light up. The age of the error is indicated by the diode that illuminates:

The first diode lights up – the last (most recent) error code is displayed

The second diode lights up – the second-last error code is displayed

The third diode lights up – the third-last error code is displayed, etc.
