S70 has recognized the DeviceNet bus does not have a conflicting address and is configured at the correct baud rate If the DeviceNet LED D17 is red or flashing red refer to section 4 3 for trouble shooting If any other LEDS are flashing this indicates an error condition Refer to Section 4 to interpret the LED error codes for corrective action Once the DeviceNet LED D17 is flashing green the S70 has become part of the DeviceNet network and is ready to be commissioned Section 3 1 5 2 4 Calibration The S70 calibration defines the limits of operation of the Series 70 Actuator between the open valve position and the closed valve position The S70 calibration is flexible and does not require that the valve be at the full opened or closed position to define the calibration end points The cams on the Series 70 which define the opened and closed positions of the valve are relative to the users requirements and can be set at any location The only exception is that the open Cam limit setting must correspond to a valve position that is more open than the Cam which defines the closed limit valve position Perform the following before the calibration 1 Before entering the calibration mode adjust the open and close limit Cams on the Series 70 to the desired position then manually adjust the valve with the Series 70 Handwheel engaged to a position midway between the Cams so then neither Cam is engaged 2000 BRAY CONTROLS Page 6 of 24
