C4 

Unbalance compensation (B9000 Version) 

 

Displayed on selection: 
"C4" in left display, "0" or "1" in right display. Factory setting is "0". 
 
Step 1 options: 
A. Spin wheel to compensate for adaptor unbalance. 
The digit "1" is displayed in the left display to indicate the step number. 
All adaptors, cones and wheels must be removed from the machine shaft. 
Spin the flange by hand in the correct direction for wheel balancing. 
Upon completion of the spin a beep is generated and the step number is incremented and displayed. Ten 
spins are required in total to perform the compensation. The user must repeatedly spin the shaft until 
this number of spins have been achieved. The machine will then beep and the function will exit. 
The machine stores the new compensation values and exits to the service menu. 
 
B. Alternatively, if C4 is already active when the service code is selected, the PLUS or MINUS keys will 
toggle the status of the code between 0 and 1. Pressing RETURN with 0 displayed cancels the code. If 1 
is displayed and return is pressed an error beep is generated as to enable the function the shaft must be 
spun. 
 
Pressing the PLUS and MINUS keys together at any stage will act like an Escape key and exit the code 
without changing anything.
