The allocation of pins on the I/O extension PCB is described
below.
Table 13: J14 Pin Listings
LED Indicators
The following table describes LED statuses for LED’s D10 through
D14 present on the I/O extension PCB.
Table 14: I/O Board LED Descriptions
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 7 is used to configure the overhang mode (see user
manual for further information) and DIP switch 8 is used to reset
default configuration. Note that once changed, DIP switch
settings are only recognized after a power cycle.
Table 15 details DIP switch settings for the I/O board. Please refer
to the Programming Guide for further information on the listed
functions.

Default Parameters
Table 9 lists the default values for each of the parameters
discussed above, that can be reset by use of switch 8 on DIP
switch array S1, followed by a power cycle.

Teach Process
The teach function allows the user to configure the parameters for
a number of functions by use of a push button on the I/O
extension PCB. The following sections detail the parameters that
can be taught to the sensor, as well as the steps associated with
this procedure.

ATTENTION
Protect the controller from ESD with proper
grounding or shunting and the use of static
control packaging and materials handling
products. Dissipate and neutralize by
grounding, ionization, and the use of
conductive and dissipative static control
materials.
