6.6. ALARM HISTORY 

 

 

The unit keeps the list of 9 most recent alarm records. 

 

A new occurring alarm will appear at the top of the list. 

 

The alarm list may be visualized on the screen or read through Modbus. 

 

The alarm list is kept in a non-volatile memory and is not affected by power failures. 

 

The alarm will be added to the list only if it is different from the previous alarm or the 

motor has run at least 6 minutes after its previous occurrence. 

 

In order to visualize the latest alarm in the history press MENU 

 button until

(alarm history 1) comes to the display.  

 

To visualize previous alarms use RUN 

 and STOP 

 pushbuttons. 

 

 

When the alarm history is scrolled the STOP 

 

button 

is always active and stops the compressor. However the  

RUN 

  

button is not active and does not run the 

compressor. To scroll the alarm history when the 

compressor is running please use only the RUN 

  

button.
