8.3 Deciphering 

Alarm 

Messages 

In front of some alarm messages you may see these designators:  
C1, C2, C3, C4, C5, C6, along with alarm text.  
C stands for component and 1,2,3,4,5, and 6 refer to the bin that is causing the 
alarm. It is important to look at the alarm text and check to see if there is a prob-
lem with the component bin number listed. 

8.4  Alarm messages and correction 

Alarm Message 

 

Possible Cause 

Solution 

 

If you press 

 and 

the component is set at “_ _ 
_”, the batch will continue 
and an alarm message is 
recorded.  

 If you press 

 and 

the component is set at 
“Stop”, the component the 
control is alarming on will 
stop dispensing and an  
Error Stop Message will be 
received.  The alarm mes-
sage will be recorded. 

Note:  C = component   
1,2,3,4,5, and 6 = the hop-
per/bin number 

  Dosing time is less than 

zero or greater than 100 
and therefore unusable. 

Perform a material rate cali-
bration. See section 7.7.2 
Calibrating.
