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:
Closed, the value should be between – 1000 and +1000 for a reciprocating
valve or a 60° rotation rotary valve.
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.
