Calibration
If the calibration procedures are not performed cor-
rectly, unsatisfactory truck performance or logged
events may result.
When to Calibrate
• When ACCESS 1, 2, 3, or 7 is replaced, full truck
calibration is required.
• When any potentiometer, encoder, or component
used to mount or position a potentiometer or en-
coder is replaced.
During most calibrations, you can press the right arrow
to view the component input or output value. You can
use this as a troubleshooting tool if there are problems
with the calibration process by comparing values with
a known working truck.
Calibration Error Message
The message "Calibration Failed" may be displayed if
required calibration criteria are not met. This message
may result from improper sequencing of switches to
component issues. If this message is displayed during
calibration, press the enter arrow to repeat calibration
procedures.
