ALARMS AND EVENTS LIST 

12.1

 

Description of alarm messages 

During machine operation, the user is aided by 

ALARMS

 or 

ALARM MESSAGES

 which 

make use of visual signals on the operator display panel to advise of possible anomalies in 
progress and machine alarms which have intervened. 

Intervention of an ALARM during operation of the system is signaled to the user by a 
message on the operator panel.  

The alarm which appears on the panel remains active until the cause of intervention is 
removed. 

The intervention of an alarm stops the wash cycle currently in progress.

display.
