To order a positioner with special span spring, specify: Positioner complete with R620-____ spring for ____ psi span.
SELECTING CORRECT SPAN SPRING FOR VARIOUS INSTRUMENT RANGES
"Zero" adjustment (pressure where actuator begins to move) of the standard positioner may be set as low as 3 psi, and as high as 9 psi. Many different instrument ranges can be accommodated, by setting different "zero" points, and by using various span springs. If, for example, an order specifies a positioner for a 5 to 11 psi instrument signal range, determine the correct span spring by subtracting the lower range number from the higher range number; 11 – 5 psi = 6 psi. Select the 6 psi span spring (R620-2113) substituting it for the standard spring. Set the zero adjustment screw so that the air motor begins to move with a 5 psi signal at the control instrument connection. An air signal, from 5 to 11 psi will then provide the full 26° travel. To order Conversion Kit for 1600, specify: 1600-P (includes positioner, gasket, adapter and spring) To order positioner, specify: R620-2101 positioner WARNING: Situations dangerous to personnel and property may exist with the operation and maintenance of any combustion equipment. The presence of fuels, oxidants, hot and cold combustion products, hot surfaces, electrical power in control and ignition circuits, etc., are inherent with any combustion application. Components in combustion systems may exceed 160°F (71°C) surface temperatures and present hot surface contact hazard.
