encoder counts per meter. Using this parameter, a variety of
standard, retrofit, and custom devices can be used. The setting for
the Model 2075 series towers is :

1620

If the given value does not appear to work correctly, the encoder
calibration value can be determined using the following procedure:

1. Set the encoder calibration value to 1000.

2. Insure that the tower is positioned to allow at least a meter of

travel in the upward direction at an easily measurable height,
and then set the current position reading to 000.0. NOTE: It
will be necessary to adjust the lower limit setting to allow this.

3. Using the STEP keys, adjust the height of the carrier until it is

one meter above the start point.

4. Record the reading of the display, ignoring the decimal point

(i.e. 200.0 would be 2000). This is the encoder calibration
value. NOTE: If the value is below 1000, the resolution of the
encoder is low and thus the 2090 will not provide 0.1 cm
resolution, even though the display shows that digit. If the
value has gone past 9999, the encoder has too many counts per
meter and the 2090 can not correct for it. In this case, contact
ETS-Lindgren for assistance.

5. Enter this value for the encoder calibration value and reset the

limits and position information.

6. Test the tower by moving it a known distance and comparing

the display to the measured distance traveled. It may be
necessary to adjust the encoder calibration value up or down
slightly depending on the result.
