• Turning off power at any time during the teach process cancels

the process. The previously stored values remain valid.

• The analog output is active during the teach process and the

output value represents the actual state based on the current

interrupted beams and the values taught during the current

teach process.

• Default values (analog output scaled to full length of

connected light arrays) can be reset by setting DIP switch 1:8 to

ON and cycling power.

• Connecting a different length light array pair to the controller

will result in the analog output being scaled to the full length

of the array, thus overwriting any taught values for minimum

and maximum analog output value.

• The slope of the analog output can be made positive or

negative by changing the order in which the two different

sized objects are presented during the teach process. For

example, presenting the taller object in step 2 and the shorter

object in step 3 will result in a negative slope in the analog

output.

Functional Description—Basic Model

Figure 4: Basic Model

This controller model provides a basic discrete (on/off) output

indicating the overall state of the arrays.

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. Note that once

changed, DIP switch settings are only recognized after a power

cycle.

The following table details DIP switch settings for the I/O board.

Please refer to the user manual for further information on the

listed functions.
