AVP300/301/302/200/201/202 - SVP3000 Alphaplus Smart Valve Positioner Yamatake Corporation Chapter : Troubleshooting Troubleshooting The SVP is a precision instrument and requires the same level of care as any other field device Unlike an air-actuated control valve, the SVP contains many electronic components and mechanical parts which must have proper settings and calibration Poor SVP performance is usually easy to correct by adjusting settings A Minor Failure indicates no immediate danger or serious trouble in the operation of the SVP The SVP will continue to operate normally Connecting an SFC or HART Communicator or requesting a self-diagnostic through the supervisory monitoring system (model AVP301/302/200/201/202) is necessary to discover and determine Minor Failures A Major Failure indicates serious trouble in the operation of the SVP and, if no action is taken, may lead to damage to the SVP itself Should serious trouble occur during SVP operations, the SVP will drive the valve to the fail-safe position An SFC or HART® Communicator, or the supervisory monitoring system (model AVP301/302/ 200/201/202) are used to determine Major Failures 7-1 : Using an SFC If you have an SFC connected to the SVP and a Hash (#) mark appears in the lower right corner of the screen, then an alarm condition exists To determine an error: Make sure the SFC is in the Ready State Press SHIFT + STAT to see which error conditions exist If there is more than one, then each error condition flashes for seconds The following page lists error conditions, as well as the SFC error code and text message that is returned for each error, and possible solutions Model AVP300/301/302/200/201/202 - SVP3000 Alphaplus Smart Valve Positioner 7-1 Troubleshooting Yamatake Corporation 7-2 : Using a HART® Communicator If you have a HART Communicator connected to the SVP, you can perform a selfdiagnostic: Make sure the HART Communicator is in the Ready State Select “1 Device Setup,” “3 Basic Setup,” “4 Device Information,” and finally “7 Descriptor “ Either “STATUS = OK” or “STATUS = xxx” will be displayed If a number 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 SVP still not match your requirements, or the SVP fails, contact your local Yamatake representative 7-3 : General troubleshooting If, after attaching your SVP to a control valve and performing Auto-Setup or manual calibration, you are experiencing performance problems, follow the troubleshooting steps below If the troubleshooting procedures below not fix the problem, contact your Yamatake representative SVP does not operate (no output air pressure) Confirm that the internal SVP settings for actuator size, hysteresis, etc are appropriate for your control valve For model AVP300/301/200/201, refer to “(A) Basic data settings (SYSTEM CONFIG)” on page 4-1 For model AVP302/202, refer to "5-2 : Starting Communication" on page 5-5 Make sure that the SVP feedback lever is not exceeding a 20° angle of rotation If it is, add an extension bracket to the feedback lever to provide the necessary feedback lever length Check for air leaks in air supply Check electrical input signals Check Auto/Manual switch in Auto Check the flapper and the filter clears If communication can be made with a SFC or HART ®Communicator, perform self diagnostics and take action based on errors messages See “Troubleshooting Codes” on page 7-3 7-2 Model AVP300/301/302/200/201/202 - SVP3000 Alphaplus Smart Valve Positioner Yamatake Corporation Troubleshooting Abnormal action of control valve (although output air is supplied, the control valve does not operate properly): Change the A/M switch to manual (See page 6-1) and adjust the air pressure using the regulator valve from fully open to fully closed Watch to see if valve stem moves smoothly If it does not, this may indicated galling or hardening of the valve packing Confirm that the internal SVP settings for actuator size, hysteresis, etc are appropriate for your control valve For model AVP300/301/200/201, refer to “(A) Basic data settings (SYSTEM CONFIG)” on page 4-19.For model AVP302/202, refer to "5-2 : Starting Communication" on page 5-5 Hunting, Overshoot • Change hysteresis setting from medium to heavy If problem persists, set hysteresis at heavy and change the actuator size setting to smaller PRAM numbers • Check permissible angle of rotation of feedback lever Absence of full stroke, slow response • • • Check the zero (fully closed) and span (fully opened) are properly adjusted Check the EPM drive signals are within range of 50+/-25% Check the filter and the flapper clean No communication possible with an SFC or HART Communicator: Check input signal wiring mA is required for the SVP to operate Check that the SFC or HART Communicator and SVP are wired properly For model AVP300/301/200/201, refer to "4-3 : Connecting the SFC" on page 4-4 For model AVP302/202, refer to "5-2 : Starting Communication" on page 5-5 If the SFC or HART Communicator will not power on, check the batteries Troubleshooting Codes Message LO IIN VTD FAULT A/D FAULT NVM FAULT RAM FAULT ROM FAULT SHUT ON Cause Correction Input signal is too low (3.8 mA or lower) (Valve
