Rockwell Automation 42DRP Diffuse/Analog Control - Manual (Page 2)

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 Positive 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 Ad-
justment pot. for 1VDC or 1mA (10%) when using Negative
Slope operation or to 10VDC or 20mA (2%) when using Posi-
tive Slope operation.
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 Posi-
tive 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.
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.
