Maximum Feed Rate in mm/sec. = (registration mark width in mm – 1.2) / 0.002

Example with a 5 mm registration mark:

Maximum Feed Rate = (5 mm – 1.2) / 0.002 = 1900 mm/sec.

Note: Registration marks narrower than the 1.2 mm sensing image width can be detected at feed rates less than 600

mm/sec, but the contrast is reduced due to averaging of the background and the registration mark.

Dynamic TEACH and Manual Adjust

Sensitivity may be adjusted at any time when the sensor is in Run mode by clicking the “+” and “-” buttons. Each click translates to 1/2

segment on the bargraph display. For best sensing reliability, the light and dark conditions should register equally distant from the

switchpoint on the bargraph display.

Table 1: Contrast

Bargraph Display Segment (following TEACH)

Relative Contrast/Recommendation

6 to 8

Excellent: Very stable operation.

4 to 5

Good: Minor sensing variables will not affect sensing reliability.

2 to 3

Low: Minor sensing variables may affect sensing reliability.

1

Poor: Consider an alternate sensing scheme.

Note: High contrast relates directly to sensing reliability; high-contrast sensing applications are most tolerant of

sensing variables (for example, web flutter or variations in registration mark color and print density).

Release Dynamic (+).

Teach Accepted

•

The bargraph display flashes

one segment for three seconds

to indicate relative contrast (see

Table 1 on page 6).

•

The sensor enters Run mode.

Teach Not Accepted

•

Pairs of bargraph display

segments flash in unison for

three seconds to warn of

unacceptably low contrast.

•

The sensor returns to Run mode

without changing settings.

Remote Input

Release the remote input/switch.

Setup Mode

Use Setup mode to configure the discrete sensor output response for:

4 0.04 seconds ≤ “click” ≤ 0.8 seconds

5 0.04 seconds ≤ “T” ≤ 0.8 seconds
