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:
Valve Air to Open (ATO) or Air to Close (ATC)
Actuator pressure rating
Actuator spring range
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:
“Perform a Visual Inspection” on page
42
“Use ValVue to Check Magnet Position” on page
43
Perform a Visual Inspection
Rotary Valves
Ensure that mounting has been performed as per “Mounting the SVi1000 on
Rotary Valves” on page
24.
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
30).
