Operation
LED Functions:
Yellow - comes on when label backing (web) is under the sensing area
Red - comes on when output is active - NPN sinking or PNP sourcing
Green - comes on when label over label backing is under the sensing area
Operation Features:
The CS2000 has 3 different operation features that can be changed to accommodate
individual needs. They are Output Mode, Light/Dark Operation, and Contrast Setting.
Operation Features - Output Mode:
The CS2000 has 2 different output modes - Level Shift Output and Pulse Output. Level
Shift Output is either on for the length of the web, or on for the length of the label, depending
on the Light/Dark Operation setting. Pulse Output either comes on for 2 m.s. at the leading
edge of a label, or goes off for 2 m.s. at the leading edge of a label, depending on the
Light/Dark Operation setting. Refer to Program Mode (page 12) for more information.
Operation Features - Light/Dark Operation:
The CS2000 allows you the option of having the sensor's output active on the web
(Light Operate), or having the sensor's output active on the label (Dark Operate). Light Operate
is either on for the length of the web, or comes on for 2 m.s. at the leading edge of a label,
depending on the Output Mode setting. Dark Operate is either on for the length of the label, or
goes off for 2 m.s. at the leading edge of a label, depending on the Output Mode setting.
Refer to Program Mode (page 12) for more information.
Operation Features - Contrast Setting:
The CS2000 comes with a Normal Contrast Setting and a Low Contrast Setting.
Normal Contrast Setting should be fine for 99% of labels. But with labels that offer very little
contrast between the web and the label, the Low Contrast Setting can be selected very easily.
Refer to Program Mode (page 12) for more information. Adjustments to the label sensitivity
should be made more frequently when the Low Contrast Setting is selected.
