Figure 6. Dark Set (Light Operate shown)
• Dark Set sets a threshold approximately 12.5%
above the presented sensing condition.
• Any condition lighter than the threshold causes the
output to change state.
• In Light-Operate mode, the presented condition is
the Output OFF condition. In Dark-Operate mode,
the presented condition is the Output ON condition.
To change the Light-/Dark-Operate setting, see
Sensor Setup on page 3.
• Dark Set is recommended for applications where
only one condition is known, for example a stable
dark background with varying lighter targets, or
when maximum excess gain is required.
