In Application Calibration Out Of Application Calibration
YELLOW = 20mA
RED = 4mA
NOTES:
If the Full Level (Near Target) is set to 20mA, then the Empty Level (Far Target) must be set to 4mA.
If the Full Level (Near Target) is set to 4mA, then the Empty Level (Far Target) must be set to 20mA.
Most common issue is setting 20mA & 4mA to same target. Unit will not function properly if this is the case.
Sensor can be pointed at wall, floor, or solid object to do calibration.
OR
FULL 20mA (Near Target)
1.
Power on sensor. STATUS LED should be Green. Set
near target (Full Level). Aim sensor to near target.
2.
Push and hold Calibration Button until LED turns YEL-
LOW (20mA). Approximately 2 seconds. Release but-
ton. LED should flash and return to Green to
acknowledge the calibration. If not repeat step 1.
EMPTY 4mA (Far Target)
3.
STATUS LED should be Green. Set far target (Empty
Level). Aim sensor to far target.
4.
Push and hold Calibration Button until LED turns RED
(4mA). Approximately 7 seconds. Release button.
LED should flash and return to Green to acknowledge
the calibration. If not repeat step 3.
CALIBRATION: 20-4mA
FULL 4mA (Near Target)
1. Power on sensor. STATUS LED should be Green. Set
near target (Full Level). Aim sensor to near target.
2. Push and hold Calibration Button until LED turns RED
(4mA). Approximately 7 seconds. Release button.
LED should flash and return to Green to acknowledge
the calibration. If not repeat step 1.
EMPTY 20mA (Far Target)
3. STATUS LED should be Green. Set far target (Empty
Level). Aim sensor to far target.
4. Push and hold Calibration Button until LED turns
YELLOW (20mA). Approximately 2 seconds. Re-
lease button. LED should flash and return to Green
to acknowledge the calibration. If not repeat step 3.
CALIBRATION: 4-20mA
