OPERATING DISTANCE SELECTION
The maximum operating distance is based on installing the control in a relatively clean environment. Normal industrial environment
actually ranges from moderately Dusty to extremely Dirty.
Greater operating margin (excess gain) may be required, which
can be obtained by reducing the operating distance of the control.

CALIBRATION PROCEDURES
Before starting the calibration procedures for Analog Output or
Setpoint Output, be sure the control is at the same temperature as it’s
environment; it adjusts after approximately 15 minutes. Setpoint Calibration is best performed after calibration of the Analog Output has
been completed.
Calibration of Analog Output
Calibration of the Analog Output is done with a Voltmeter or an
Ammeter. When calibrating the Voltage Output, connect the Voltmeter between Terminal 2 (+) and the negative power supply, terminal 1
(--). Select the Voltmeter Scale for 10VDC. When calibrating the Current Output, install the Ammeterbetween Terminal2 (--) and the positive power supply Terminal (+), or the positive of a separate power
supply when used. Select the Ammeter scale for 20mA (DC).
1. With Selector Switches 1 and 2, select Analog Current or Voltage
Output.
2. With Selector Switches3 and 4, selectPositive or Negative Slope
operation.
3. Set retroreflective target at 2 (.61m). Adjust the Analog Output
Calibration pot. for 10VDC or 20mA (2%) when in Negative
Slope operation to 1VDC or 1mA (10%) when in Positive Slope
operation.
4. Set the retroreflective target at the desired range. 15 (4.57m)
maximum, 5 (1.52m) minimum. Adjust the Sensing Range Adjustment pot. for 1VDC or 1mA (10%) when using Negative
5. Bring the object to be detected at 1 (.3m). Re-adjust the Analog
Output Calibration pot. for 10VDC or 20mA (2%) when using
Negative Slope operation or to 1VDC or 1mA when using Positive Slope operation if necessary.
6. Place the object to be detected at the desired range. Re-adjust the
Sensing Range Adjustment pot. for 1VDC or 1mA (10%) when
using Negative Slope operation or to 10VDC or 20mA (2%)
when using Positive Slope operation if necessary.
The Analog Output is now calibrated.
Calibration of Setpoint Outputs
1. Place the object at the distance where the Setpoint Output A is to
come on.
2. Adjust the Setpoint pot. A to turn on Output A at this point. (Red
LED turns on.)
3. Place the object at the distance where the Setpoint Output B is to
come on.
4. Adjust the Setpoint B to turn on Output B at this point. (Green
LED turns on.)
This completes the calibration of Setpoint Outputs.
Slope operation or to 10VDC or 20mA (2%) when using Positive Slope operation.
INSTALLATION
The control must be securely mounted on a firm, stable surface or support. A mounting
which is subject to excessive vibration or shifting may cause intermittent operation.
