Use ValVue to Check Magnet Position
To check the magnet using ValVue:
1.
Connect to the positioner in accordance with the ValVue instructions.
a.
Ensure the positioner has been installed and set up with a HART® modem in a HART®
compliant communications loop, if required, install ValVue on the computer that is
connected to the HART® modem.
b. Run ValVue.
c.
Select the installed positioner from the list of Connected Devices.
d.
Select the Check tab to view the current operating conditions of the selected positioner.
2.
Read Raw Position data. When the valve is:
o
Closed, the value should be between – 1000 and +1000 for a reciprocating valve or a
60° rotation rotary valve.
o
At mid-travel, the value should be between –1000 and +1000 for a greater than 60°
rotation rotary valve.
Step 4: Checking the Air Supply
To check the air supply:
1.
Turn on the air supply.
2.
Adjust the filter regulator.
3. Supply pressure must be a minimum of 5 psi greater than the spring range of the actuator
but may not exceed the rated actuator pressure. Refer to the valve or actuator instruction
manual.
4. Inspect the tubing connections between the filter-regulator and the positioner for leaks.
5.
Verify that the tubing is not bent or crushed.
6. Verify that all fittings are leak tight.
CAUTION
Do not use Teflon pipe seal tape. The Teflon tape
can shred into particles that are harmful to the
pneumatic components.
