Repeat OK to read all messages until the display returns to “read status” 12. Scroll down to line 6 clear status, press -> 13. If clear fault codes not completed appears, press OK and read the message (Position Error, for example) or go to the troubleshooting guide. 14. Correct the problem (Is the air supply on?), and then go to clear status until Clear Fault codes Completed appears. 15. Press OK. Diagnostics The SVI II ESD provides two types of diagnostic information; the continuous diagnostics that require no user configuration for which no valve movement occurs and Partial Stroke Testing (PST) diagnostics that you can configure and run at any time. You can also manually run a proof test (see page 11). Partial Stroke Test Diagnostics The SVI II ESD is capable of partially stroking the valve to detect failures in the final control element assembly. The PST is configured using the pushbutton display or through ValVue ESD. Upon detection of a failure or deviation from the user configurable conditions the annunciation channel SW 1 sets its state to low. The PST can be configured to start automatically or can be initiated through setting the current input to 16.4 mA. +/- 0.1mA, local control panel pushbutton, or initiated locally by an operator. When configured to run automatically or when initiated through a safety rated logic solver, additional diagnostic credit can be taken for the PST. In addition to the safety rated I/O, HART communications are available to provide additional information on the SVI II ESD status. Additional diagnostic functions include: With ASD or A/DSD modes, the device is capable of capturing and storing the shutdown event when the safety function is engaged and / or when the valve is positioned using the control signal (4-20 mA or 0-24 VDC). The SVI II ESD can provide general information of the device’s sensor health (Temperature, Actuator Pressure, Air supply, Current, etc.). Capable of annunciating faults resulting from a PST. 56
Setup, Calibration and Partial Stroke Testing Partial Stroke Testing Discrete output (SW1) is de-energized for any fault related to the I/P, relay, or valve/actuation assembly, resulting from a PST or during normal operation. For most fault conditions, the ESD device attempts to remain in the energized state until an ESD command is given (unless specified otherwise during setup). Key components of Safety Instrumented System (SIS) are final control elements such as emergency shutdown devices, i.e. the SVI II ESD. The SVI II ESD and it’s associated valve are not continually moving like a typical control valve, but are normally expected to remain static in one position and then reliably operate upon an emergency situation. Valves that remain in one position for long periods of time can be become stuck in that position and may not operate when needed. To ensure the integrity of the ESD valve the SVI II ESD requires periodic testing. One of the great features of the SVI II ESD is the ability to test the safety valve on-line, without removing the safety valve from the SIS. The SVI II ESD allows you to automatically, or on demand perform a Partial Stroke Test (PST) which returns relevant variables about valve operation and can allow you to detect potentially dangerous failures. PST Configuration Before running PST, configure the parameters; travel, maximum pressure, maximum time, ramp speed, and spring. You can configure PST parameters from the pushbutton display and also using ValVue ESD. Refer to Table 6 on page 46 for PST configuration parameters. PST Configuration with Display When using the LCD display to configure PST: 1. Aces the PST Configuration (PST CONF) menu. (Refer to Figure 22 on page 51 for menu structure.) 2. Scroll through each PST parameter and adjust accordingly. PST Configuration with ValVue ESD When using ValVue ESD to configure PST: 1. Select the Configure Screen in ValVue ESD. 2. Set the PST parameters to the appropriate settings. 3. Apply and save changes. 57
