Calibration of Analog Output

Calibration of the Analog Output is done with a Voltmeter or an

Ammeter. When calibrating the Voltage Output, connect the Voltme-

ter between Terminal 2 (+) and the negative power supply Terminal 1

(--). Select the Voltmeter Scale for 10VDC. When calibrating the Cur-

rent Output, install the Ammeter between Terminal 2 (--) and the posi-

tive 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 Switches 3 and 4, select Diffuse or Retroreflective

operation.

Retroreflective Operation

1. Set retroreflective target at 2 (.61m). Adjust the Analog Output

Calibration pot. for 10VDC or 20mA (2%).

2. Set the retroreflective target at the desired range. 15 (4.57m)

maximum, 5 (1.52m) minimum. Adjust the Sensing Range Ad-

justment pot. for 1VDC or 1mA (10%).

3. Bring the retroreflective target back to 2 (.61m). Re-adjust the

Analog Output Calibration pot. for 10VDC or 20mA (2%) if

necessary.

4. Place the retroreflective target at the desired range. Re-adjust the

Sensing Range Adjustment pot. for 1VDC or 1mA (10%) if

necessary.

The Analog Output is now calibrated for Retroreflective operation.

Diffuse Operation

1. Place the object to be detected at 1 (.3m). Adjust the Analog

Output Calibration pot. for 10VDC or 20mA (2%).

2. Set the object to be detected back to the desired range, 5 (1.52m)

maximum or 3 (.91m) minimum. Adjust the Sensing Range Ad-

justment pot. for 1VDC or 1mA (10%).

3. Bring the object to be detected at 1 (.3m). Re-adjust the Analog

Output Calibration pot. for 10VDC or 20mA (2%) if necessary.

4. Place the object to be detected at the desired range. Re-adjust the

Sensing Range Adjustment pot. for 1VDC or 1mA (10%) if

necessary.

The Analog Output is now calibrated for Diffuse operation.
Calibration of Setpoint Outputs

1. Place the retroreflective target 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 retroreflective target 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.)

Note: Be aware that in the retroreflective mode, when setting the

range beyond 11 (3.35m), white paper response may occur

between 1 (2.54cm) and 1 (.3m).

This completes the calibration of Setpoint Outputs.

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.
