QUICK USER MANUAL

Simple Troubleshooting... The Control box blinks -E1- If the box indicates -E1- it MOST LIKELY means that the 4-20 mA control is NOT CONNECTED, (be sure to seat the Multi Stranded cable securely) and make sure that there is AT LEAST 3 mA. No connection to the 4-20 mA control line will throw this error. Use a FLUKE DVM, set in the Current Mode to MAKE SURE that the 4-20 mA signal does indeed vary from 4 to 20 mA. You do NOT have to cycle the power to clear the error after you connect a proper 4-20 mA Control Signal. This can ALSO happen if the input power is reversed momentarily. Just connect the DC 24+ to the DC24+ and the 1 to the DC 24 -. Provide at least 850 mA of current. The valve does not fully close with 4 mA or does not fully open with 20 mA If a user happens to push the programming buttons incorrectly the controller can go out of calibration. The controller can be easily instructed to self calibrate for 4-20 mA for the 0-100% open position.  Use the Automatic Calibration method shown on page 9 of the manual. Be careful with "live processes" because the valve will go from closed to full open and take about 80 seconds to complete. It does not matter what your 4-20 mA command signal is set to at this point. Details here... Press the A/M and the DOWN button (the two OUTER buttons) AT THE SAME TIME and hold until the display circles around, like a race track, then release (3 seconds or so). The calibration has been initiated when the race track circles around and it takes about 80 seconds to complete the entire process. If the valve is currently in the closed position it will likely display a number in the range of 28 and "measure" it for a while. If not closed it will drive the valve to the closed position and then then advance to the full open position and likely indicate a number of around 965. After a moment it will tweak the valve to the fully open position and the display will blink 100.0 indicating it is done. Hit the A/M button to resume normal operation. The valve will go to the position commanded by the 4-20 mA signal. 4 mA (or below) is 0.0% and 12 mA is 50.0% and 20 mA is 100.0%
