This instruction addresses Errors 55, 57, or 59 that
occur when the value read by the sonar is insufficent
to obtain a correct runout measurement.
1. Make sure the Radial Runout and Lateral Runout
Sonars are aligned correctly.
2. Set Encoder to pulley gap at 0.040”.
3. Go to Self-Test Screen (Green Screen) and verify
that the Encoder is operating correctly and the Sonar is
reading correctly. Use the Sonar check tool (p/n
8114165) or a tape measure and flat card for a target.

4. For XR 1800/1850 software (version 1.06 and
higher) and XR 1750 software (all versions):
From the Green Screen press button 2 for 2 seconds
and then the Encoder Test Screen will appear.
5. With hood down Press START to run the Encoder
Test. It will work with or without a wheel on the
machine. At the end of the Test Run lines of text will
appear below the graphs:
Line 1: > No. ck encoder: ENCA=64 ENCB=64
Both of these values should be 64, if not, an IN or
OUT encoder adjustment (from the 0.040” gap) is indi-
cated.
Line 2:
XR 1800/1850 Models
> Timing signal: ENCA=2000-3500
ENCB=3500-5000
XR 1750 Model
> Timing signal: ENCA=1500-3000
ENCB=2500-4000
(These numbers will vary within the range and some
even outside of the range. The important thing is to get
rid of Line 3: Error reset.)
If the encoder is not set correctly, a third line of text
will appear:
Line 3: > Error reset ENCA or Error reset ENCB
(If one of the above messages appear: Slightly loosen
the small nuts holding the encoder PCB to the bracket.
For ENCA rotate the PCB slightly upward and for ENCB
rotate the PCB slightly downward. Then re-tighten the
small nuts and rerun the Encoder Test.
Rotate the PCB until the Error reset messages are
eliminated.
6. Now, if any Error 55, 57, or 59 appears then the
problem is most likely a very rough tread pattern or
alignment of the sonar. Move the sonar to a different
spot near the center of the tread.
