Masoneilan SVi1000 Positioner Quick Start Guide =| 43Step 5: Verify Wiring ConnectionsSee C “Determining an SVI Positioner Compliance Voltage in a Control System” on page 63.CAUTION Improperly or inadequately grounded installations can causenoise or instability in the control loop. The internal electroniccomponents are isolated from ground. Grounding the case isunnecessary for functional purposes but grounding the case maybe necessary to conform to local codes.NOTE For split range installations the output voltage must be sufficientto operate two positioners (11 V @ 4 mA, 9 V @ 20 mA) and theexpected voltage drop in the cable.Step 6: ConfigurationThis section describes configuration using the local user interface pushbuttons. You can also useValVue and a PC with a HART® modem or a HART® Handheld Communicator. 5 “ValVue Softwareand the SVi1000” on page 49 describes ValVue software functions.Prior to changing the SVi1000 configuration, check the existing configuration. Use the proce-dures that follow to: run auto stops, run open stop adjustment and perform preset or auto tune.WARNING These procedures can cause the valve to move. Before proceedingensure the valve is isolated from the process. Keep hands clearfrom moving parts.Auto Find StopsThe process first exhausts the actuator and measures the position, then fills the actuator andmeasures the position. From these measurements the valve position is determined. Correctioncan be made for nominal valve travel if it is less than full travel. To perform auto find stops:1. Set the air action (0-7 for ATO or 8-F for ATC).2. Press auto find stops button until green LED 1 illuminates, then release(approximately 2 seconds to turn on and release before 7 seconds). The unit goesinto a Commission Process and green LED 1 blinks until the process completes.The auto find stops process occurs. When the process is complete, the unitautomatically returns to Normal mode.Press Cancel to abort the process and the green LED 1 goes off, the device returnsto Normal mode and no changes occur.
