Calibration Troubleshooting:
13. If the time to run for calibration is less than 4 seconds, the cab console will display TIME TOO LOW.
Pressing the FUNCTION key will bring up the ENTER TARGET AMOUNT screen. The target should
be raised to increase the calibration time. If the time is greater than 255 seconds, the cab console will
display TIME TOO HIGH. Pressing the FUNCTION key will bring up the ENTER TARGET AMOUNT
screen. The target should be lowered to decrease the calibration time.
14. While rate calibration is running, one of four error messages may be displayed:
Pressing FUNCTION will exit rate calibration from these error screens.
Message Cause Solution
COMM TIMEOUT Power to or communication
with the external controller
was interrupted during cali-
bration. Check power and communi-
cation connections from the
cab console to the external
controller and rerun calibra-
tion.
TIME OVER LIMIT The external controller ran
too long in calibration. Rerun calibration. If the
same message appears, call
technical support.
USER TERMINATED The engage key was
pressed during calibration. Rerun calibration.
CALIBRATE ERROR The drive did not turn when
calibration began. Check encoder cable and
connection, solenoid cable
and connection, and hydrau-
lic lever position.
