Positioning the sensor shaft

Prior to coupling the sensor shaft to the valve shaft, the user should ensure the sensor shaft is not in the
"no change zone" anywhere within the usable range of the valve. Do this by following these procedures:
If the desired rotation of the sensor shaft when installed in the application is counterclockwise (CCW) then
rotate the shaft a full rotation clockwise (CW) and then at least 45° CCW.
If the desired rotation of the sensor shaft when installed in the application is CW then rotate the shaft a full
rotation counterclockwise (CCW) and then at least 45° CW.
The amount of rotation in the desired direction (45° rotation) will affect the useable range of the sensor. To
achieve the full 250° rotation, do not rotate the shaft back more than 55°.

Scaling or Converting the Engineering Units

Table 3 outlines the procedure for scaling engineering units to a percentage that matches to the application.
Table 4 outlines the procedure for converting engineering units from percentage to angular degrees.

Step Action
In order to speed up the process of scaling the engineering units, it is recommended to change the update
rate of the sensor prior to adjusting the engineering units. Follow step 1 to change the update rate.
1 Changing the update rate (after device has been commissioned)
1.1 In the Offline window, double-click on the WCX transducer block (small rectangle with a T inside). The
parameters page will open.
1.2 In the Configuration tab, note the current update rate setting. If it is set to the default value of 30 seconds,
change the "Period" to 1 second and click OK.
1.3 In the Offline window, right-click on the WCX Main block and click Load.
1.4 Ensure that "State to Load" is set to OOS and "Post Load State" is set to Normal, and that both boxes at the
bottom of the window are checked. This will change the update rate on the sensor and re-load it.
WARNING
The following steps require reading the sensor output. If the sensor is currently installed in a hazardous
atmosphere, reading this output should be done via Wireless Builder or a mobile station. Do not remove
the cover from the sensor in a hazardous atmosphere.
2 Scaling the engineering units.
2.1 Prior to performing this procedure, the sensor should be mounted in the application and the sensor shaft
should be coupled to the valve.
2.2 In Wireless Builder, verify the range units are set to their factory defaults of EU@100% = 314 and EU@ 0%
= -4. If they are not, follow the steps in table 4 to reset the factory defaults.
Position the valve to the desired 0% location. Wait until the output stabilizes and record the sensor output
