2-2. Installing SVX Smart Valve Positioner for Rotary Valve designed for use in combination with rotary valve. The SVX weighs about 1.8 kg. It should be attached in the same way you would attach a conventional current-pneumatic positioner. CAUTION • Do not install the SVX near a large transformer, high-frequency furnace, or other equipment that generates a magnetic field. - Page 19 Procedure for fork lever type step Procedure The SVX comes with an actuator mounting kit appropriate to your control valve and actuator. Fasten the mounting plate to the rear of the SVX securely, using the four hexagon head bolts (M6 × 12) and spring washers provided. Fasten the SVX (mounting plate) securely to the actuator's mounting structure using the bolts and washers provided.

Page 29: Chapter 3. Operation
Chapter 3. Operation 3-1. Auto-setup Auto-setup is a unique program for automatically making various positioner adjustments. After installing your SVX, auto-setup should be performed. The built-in zero and span adjustment switches on the SVX provides non-interactive closed and open valve position setting. - Page 30 The following valve actuator characteristics are automatically detected during autosetup: „ Zero and span adjustment (However, as a default, the span point is taken to be 0% of the overstroke. If a span adjustment is performed after auto-setup completes, change the overstroke value and save the changed value.) „...

Page 54: Maintenance
4-6. Maintenance 4-6-1. Mode The HART® version has two modes. One is “In service” and the other is “Out of service. ” When performing calibration or adjustment, or when changing settings, the control valve will move, so first verify that these operations will not result in problems that could adversely affect plant operation. -
Page 55: Dummy Input Signal
4-6-3. Dummy input signal Sets the input signal via communication, regardless of the value of the input signal from the controller. This function can be effective when, for instance, isolating problems during troubleshooting. For example, if the control valve does not move in response to input signals from the controller, but the valve operates correctly in response to the simulated current input, it follows that the problem is somewhere between the wiring and the host system. -

The SVX will continue to operate normally. Connecting the Field Communication Software (model CFS100) or HART Communicator or requesting a self-diagnostic through the supervisory monitoring system (model SVX100/102) is necessary to discover and determine Minor Failures. A Major Failure indicates serious trouble in the operation of the SVX and, if no action is taken, may lead to damage to the SVX itself. -
Page 66: General Troubleshooting
If, after attaching your SVX to a control valve and performing Auto-S etup or manualcalibration, you are experiencing performance problems, follow the troubleshooting steps below. If the troubleshooting procedures below do not fix the problem, contact your Azbil Corporation representative. SVX does not operate (no output air pressure) - Page 67 Abnormal action of control valve (although output air is supplied, the control valve does not operate properly) step Procedure Change the A/M switch to manual (See page 59) and adjust the air pressure using the regulator valve from fully open to fully closed.
