EV8611CD was reading -5% on EPICS suggesting it was closed. However visual inspection of the valve stem suggested that perhaps it was not fully closed. Cycling it a few times seems to have resolved the problem. Could you check that all is well, particularly with the LVDT calibration? <br><br>2. EV8611JT. <br>The EPICS symbol did not turn red on valve closure. If it displayed a large negative number (e.g. -1.17%), then the symbol turned red, otherwise, if it displayed just -0.5%, it remained green. <br><br>Could all the other valves be behaving this way too? <br><br>Regards <br><br>Ruben</div></div><br></div></div></body></html>
