"Door Closed" and "Door Open" patterns are independently adjustable. It is necessary to adjust the pattern
for a closed door, and then to adjust the pattern again when the door is open. The following functions may be
independently adjusted for each door position:
• Sensitivity
• Pattern width
• Pattern depth
The following functions apply to both "Door Closed" and "Door Open" positions:
• Auto-Learn time
• Immunity (“medium” and “high” affect interpretation of objects in detection field relative to background;
Learn time is unaffected)
• Frequency
• Output configuration
• Door control mode
• Hold time
• Interface type
