3.2.4 Offset Percent
The Offset Percent is used during the Window, Light, or Dark SET methods. The threshold(s) are positioned a programmable % offset
from the taught condition.
The allowable offset percent range varies based on the response speed, teach method and sensitivity settings as shown below:
Teach Method Response Speed Sensitivity Offset % Range
Window Set, Light Set 50 µs, 250 µs High 2 to 98%
Standard 5 to 95%
Low 10 to 90%
500 µs, 1000 µs, 2000 µs High 1 to 99%
Standard 2 to 98%
Low 5 to 95%
Dark Set 50 µs, 250 µs High 2 to 999%
Standard 5 to 999%
Low 10 to 999%
500 µs, 1000 µs, 2000 µs High 1 to 999%
Standard 2 to 999%
Low 5 to 999%
3.2.5 Auto Thresholds
Auto Thresholds can be programmed to be ON/OFF. The Auto Thresholds algorithm continuously tracks slow changes in the taught
condition(s), and optimizes the threshold(s) to provide for reliable sensing. For Two-Point and Dynamic TEACH, the algorithm optimizes
the threshold to be centered between the light and dark conditions. For Window, Light, and Dark SET, the algorithm optimizes the
threshold(s) to maintain the programmed Offset Percent from the taught condition.
• After programming Auto Thresholds to ON, it is highly recommended to re-perform the TEACH/SET method
• Manual Adjustments are disabled when Auto Thresholds are ON
• Auto Thresholds are automatically disabled in Calibration SET (see Calibration SET on page 20)
• Severe contamination/changes in the taught condition can prevent the Auto Thresholds algorithm from optimizing the
threshold(s). If this occurs, the DF-G2 enters a Threshold Alert or Threshold Error state. See Troubleshooting on page 21 for
more explanation.
