:
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.
