Step 1: Inspect the Actuator, Linkages, or Rotary Adapter
1.
Verify that the mounting has not been damaged in shipment for a pre-mounted SVi1000,
physically inspect the actuator and linkage.
2.
Record the following information for the configuration checkout:
o
Valve Air to Open (ATO) or Air to Close (ATC)
o
Actuator pressure rating
o
Actuator spring range
o
Inherent trim characteristic of the control valve; linear, equal percentage, or other.
NOTE
Refer to the valve data sheet or model number of control
valve.
Step 2: Verify Mounting and Linkage Adjustment
Inspect the mounting and make any needed adjustments before running the positioner and
checking the digital configuration.
Step 3: Checking the Magnet
There are two methods of checking the SVi1000 magnet:
o
Perform a Visual Inspection on page 38
o
Use ValVue to Check Magnet Position on page 39
Perform a Visual Inspection
Rotary Valves
o
Ensure that mounting has been performed as per Mounting the SVi1000 on Rotary
Valves on page 22.
Reciprocating Valves
1.
Ensure the adjustable link turnbuckle is parallel to the valve stem.
2.
Ensure proper mounting by verifying that the hole in the lever aligns with the alignment hole
in the bracket when the valve is in the closed position. Ensure the bracket is mounted using
the proper holes (see Table 3 on page 27).
