Dark SET
• Sets a threshold a programmable % offset above the presented condition
• Any condition lighter than the threshold condition causes the output to change state
• Threshold can be adjusted using “+” and “-” rocker button (Manual Adjust)
• Recommended for applications where only one condition is known, for example a stable dark background with varying lighter targets
• See Program Mode on page 3 for programming the Offset Percent setting
NOTE: Offset Percent MUST be programmed to Minimum Offset to accept conditions of no signal (0 counts).
A single sensing condition is presented, and the sensor positions a threshold a programmable % offset above the presented condition.
When a condition lighter than the threshold is sensed, the output either turns ON or OFF, depending on the LO/DO switch setting (see
LO/DO Switch in Top Panel Interface on page 2).
