C74  Indication of the Position Counter 

 

Displayed on selection: 
A positive integer representing encoder increments (512 increments from 0 – 511). This represents the 
angular wheel position. If the wheel position subsystem is not initialised (possibly because the machine 
has just been turned on and the system requires at least one revolution to initialise) "buSY" is displayed 
until a value is available. 
 
Step 1 options: 
Rotate the wheel to view the encoder increments changing with the wheel rotation. 
 
Step 2 options: 
NOTE: To perform this test you will have to remove the drive belt from the measuring shaft if 
you are testing a motor driven balancer (b9450 / b9460). 
 
A. To test the encoder handspin the shaft mounted wheel clockwise (measuring direction) and then press 
the RETURN key. After a few seconds "539" should be displayed. 
 
B. To test the encoder handspin the shaft mounted wheel counter-clockwise and then press the RETURN 
key. After a few seconds "551" should be displayed. 
 
Pressing the PLUS and MINUS keys together at any stage will act like an Escape key and exit the code. 
Pressing the RETURN key will also exit the code. 
 

C75  Indication of all voltages supplied to the analog-to-digital converter 
 

Displayed on selection: 
A 3 digit voltage level is displayed in the right display. An identifier from the range (a)"de1", (a)"de2", 
(a)"d0" – (a)"d23" indicating which A/D channel is being shown, is displayed in the left display. 
 
Step 1 options: 
Pressing the PLUS and MINUS keys cycles through the list of A/D channels. 
Pressing the PLUS and MINUS keys together at any stage will act like an Escape key and exit the code. 
Pressing the RETURN key will also exit the code.
