Chapter 5. Maintenance and Troubleshooting
5-1. Troubleshooting
The SVX is a precision instrument and requires the same level of care as any other field device.
Unlike an air-actuated control valve, the SVX contains many electronic components and
mechanical parts which must have proper settings and calibration.
Poor SVX performance is usually easy to correct by adjusting settings.
A Minor Failure indicates no immediate danger or serious trouble in the operation of the SVX.
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. Should serious trouble occur during SVX
operations, the SVX will drive the valve to the fail-safe position. The Field Communication
Software (model CFS100) or HART Communicator, or the supervisory monitoring system
(model SVX100/102) are used to determine Major Failures.
5-1-1. Using the Field Communication Software (Model CFS100)
Refer to the operation manual for Smart Valve Positioner (CM2-CFS100-2010)
5-1-2. Using a HART Communicator
If you have a HART Communicator connected to the SVX, you can perform a selfdiagnostic:
step Procedure
1 Make sure the HART Communicator is in the Ready State.
2 Select [5. Device Status] >> [2. Failures] or [3. Notices].
3 If a message is displayed, see the following page for a list of error conditions as
well as the HART error code and possible solutions.
If after reading this troubleshooting section and solutions, the specifications of the SVX still
do not match your requirements, or the SVX fails, contact your local
