RF100 Series DO INDUCTION LOAD (SOLENOID OR RELAY) USING A SNUBER DIODE IS HIGHLY RECOMMENDED DO# EXTERNAL POWER CONTROL DCOM Figure 9. Solid State Relays - Discrete Output The Discrete Output on the I/O termination board can be used in: • Toggle mode • Latching mode • Timed mode Calibration and Configuration All field/process inputs must be calibrated to the full range input of the installed sensors. Analog Inputs Analog Input calibration routines support a 2-point calibration. The low-end or zero reading (Set Zero) is calibrated first, followed by the high-end or full-scale reading (Set Span). The calculated and diagnostic analog inputs, such as instantaneous flow, accumulated flow, barometric pressure, input voltage, Board temperature, and Logic voltage, are not designed to be field calibrated. Supported inputs with the 2-point calibration are: • P1 Inlet pressure • P2 Outlet pressure • P3 Auxiliary pressure • Travel • I/O Board AI1 • I/O Board AI2 A brief description of the calibration procedure for these inputs is described below. Refer to the RegLink Software User Manual for additional information. Pressure Sensors The pressure sensors are factory calibrated for their full scale rated pressure. Routines support a two point calibration at zero (open to atmosphere) and at full scale pressure. The general procedure is: 1. Select Tools>Configure Device to display the Configuration window. Select the AI point and select the AI Calibration tab. 18 2. Click the calibrate button. 3. Calibrate the zero value for the pressure input. This can be done by referencing the sensor to atmospheric pressure. Enter the tester value (in engineering units) and click the Set Zero button. In this case the tester value would be “0”. 4. To calibrate the span value (100% of full scale range) for the pressure input, apply pressure to the sensor for the full scale range. Enter the Tester Value (actual pressure in engineering units) and click the Set Span button. Be sure to allow enough time for the Live Reading to update and stabilize. 5. Confirm that the Live Reading is correct and click Accept or Cancel. If the Live Reading is not correct, select cancel and repeat the procedure. 6. Repeat for each sensor. Travel Sensor The travel sensor on the Type RF100 must be calibrated to the travel of the regulator. Routines support a two point calibration at zero (regulator closed) and at full scale (regulator wide open). The general procedure is: 1. Select Tools>Configure Device to display the Configuration window. Select the AI point for travel and select the AI Calibration tab. 2. Click the Calibrate button. 3. Calibrate the zero value (0% of range) for the Travel. This should be with the regulator pressurized and in lock up. Enter “0” for the tester value and click the Set Zero button. Note Full stroke of the regulator must be achieved and should be verified to insure RegFlo instrument accuracy.
