Additionally, the CAN and RS485 controller models offer the
flexibility of adjusting these settings through use of specified
commands over the serial interface.
Resetting Default Parameter Settings
All controllers are shipped with default parameter values, that can
be changed through the teach process for the I/O model and
through serial commands for the RS485 and CAN models. The
default parameters can be reset in all models through the
following procedure:
• Turn controller power off.
• Set switch 8 on DIP switch array S1 to ON.
• Turn controller power on.
• Set switch eight on DIP switch array S1 to OFF.
• Default settings should now be restored.
Functional Description—Analog Model
Figure 3: Analog Model
The analog controller model offers either 4…20 mA or 0…10V
(current or voltage selectable via DIP switch) output proportional
to target height, width, or position. The output is automatically
scaled to the length of the connected arrays, so most applications
do not require additional adjustments. A teach button is available
for applications that require customized scaling of the output.

DIP Switch Settings
DIP switches 1 through 6 on the S1 DIP switch array are
configured for the various applications described below. If no
information is otherwise provided these DIP switches should
remain in the OFF position.
DIP switch 8 is used to reset default configuration.
