Single-Point Dark Set

•

Sets a threshold slightly above the taught condition

•

Any condition lighter than the threshold condition causes the

output to change state

•

Threshold position is adjustable using the “+” and “-” buttons

(see Manual Adjust on page 10)

•

Recommended for applications where only one condition is

known, for example a stable dark background with varying

lighter targets

A single sensing condition is presented, and the sensor positions a

threshold slightly above the taught condition. When a condition lighter

than the threshold is sensed, the output either turns ON or OFF,

depending on the Light/Dark Operate setting (see Sensor Setup on

page 10).

Dark Set and Light/Dark Operate Selection

Dark Set teaches the Output OFF condition and forces the sensor into

Light Operate (LO) mode. The sensor can be reconfigured to Dark

Operate (DO) mode after the condition has been taught (see Sensor

Setup on page 10).
