(1.3 Kg) Output Signal SENSOR SOLUTIONS /// SR1M 12//2015 Page 1 SR1M Industrial User Scalable 420mA Electrical Connection Factory Calibrated Stroke Range The full scale output signal is set at the factory to the maximum full stroke range of the sensor. The ZERO point (output = 4mA) is set at the beginning* of the stroke range (0 inches) and the SPAN point (output = 20mA) is set to the end of the range (125 inches or 175 inches depending on model). *Important The ZERO point is set at the factory with the measuring cable pulled out .125 inches from full retraction. If the measuring cable becomes fully retracted at any time when the sensor is under power, the output signal will begin to fluctuate. This is normal and fluctuation will stop as soon as the cable is extended greater than .125 inches. This is for the factory setting only and the ZERO may be reprogrammed at full retraction at any time. Cable Exit Direction Options Changing the Cable Exit Changing Measuring Cable Exit To change the direction of the measuring cable, remove the 4 mounting bracket screws and rotate bracket to one of four available positions. See figures 1 - 4 on the following pages for mounting dimensions. Changing Electrical Connector Direction To change the position of the electrical connector, remove the 4 rear cover screws and carefully separate rear cover from the sensor body. Rotate the rear cover to desired position being careful to not tangle the wiring harness that runs to the connector. SENSOR SOLUTIONS /// SR1M 12//2015 Page 2
