General Troubleshooting
This test raises the lift plate to verify motion and sensor operation. If the test is
requested for a tray not installed, an “Option Not Detected” message appears.

Reports the highest peak
during the first quarter of the
lifting interval.
2 Slack Take-up Time
(sec)
Reports the interval between
the initial power min (when the
plate is not yet engaged), and
the point where the lifting
power becomes a constant.
3 Average Lift Power
(watts)
Reports the average power
over the center ¾ of the lifting
interval.
4 Lift Contact Time
(sec)
Reports the interval from the
motor start time until the
required lift power starts to
increase due to the initial
contact with the Nudger Roller.
5 Lift Time (sec) Reports the interval from the
motor start time until plate
lifted is indicated.
