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).

Dark SET and Manual Adjust
• Moves switching threshold value up or down to make adjustments
• Slide Mode switch to ADJ to enter Adjust mode
• Press “+” to increase; press “-” to decrease
• GREEN display shows the switching threshold value
• 2 seconds after adjustment, the GREEN display will flash 3 times to confirm
• Slide Mode switch to RUN to complete operation
Remember: Manual adjustments are disabled
when Auto Thresholds are ON
