Chapter 6: Calibration Procedures
6-17
28. Press Key 5 until CHAIN VELOCITY appears. Note this value
because you need to enter it in the following step.
29. Press Key 5 until MAXIMUM CONVEYOR SPEED appears
and enter the CHAIN VELOCITY value from the previous
step. The optimum encoder value for the current line speed is
now calculated including the Calibrate Encoder Value, Encoder
Prescaler Value, and Gamma Sample Cutoff Limit.
30. While the conveyor is running at production speed, place a can
on the conveyor far enough upstream so that it does not slip on
the conveyor as it passes through the FT-70.
If the reject is late, check to be sure the encoder coupling is not
slipping. Try a rejection with a thin layer of grease on the pad.
If the resulting mark in the grease starts in the upstream third
of the pad face and is centered, then performance is acceptable.
If there are still significant early/late problems, and you are
certain that you have a standard conveyor chain, contact the
Industrial Dynamics Customer Service.
31. To store the settings in system memory, close dip switch S1-2
and then press Key 5 until SAVE DEFAULT CONSTANTS
appears.
32. Press the Arrow Key to execute. When COMPLETED appears,
open S1-2 to protect the saved settings.
33. Press Key 5 until SYSTEM DISPLAY appears and press the
Arrow Key to select the Operate Mode. This returns the FT-70
to a secured operating mode and completes the calibration
procedure.
34. If you are using this production line to produce more than one
type of container, you must repeat this procedure for each
different container type (i.e. containers with different
diameters, or line speeds).
