Revised Oct., 1983 MECHANICAL ALTERNATORS TYPES DG, OW, DR BUILD UP THE SWITCH TO MEET YOUR REQUIREMENTS FROM THE BASIC SWITCH, ROD AND FLOAT GROUPS BELOW. EXPLANATION OF FLOAT TRAVEL AND POSITION NORMAL OPERATION: Switches will cut in and cut out at the high point and low point of distance A plus B, given in the tables. Under normal conditions, as long as one pump alone is able to handle the incoming water, the pumps will alternate at this distance. With the water Type DG Shown with Rod Kit level continuing to rise, the second switch will cut in and start the second 9049 ER·5, pump when the float reaches the top of distance D. Both pumps will and Float Kit continue to run until the float returns to the low point of distance D plus 9049 HF -3 installed C, where one pump will cut out. The other pump will continue until the float reaches the low point of distance B. REVERSE OPERATION (FORM R): Both pumps will be running with the float at the low point of distance B. With the float rising to the top of distance B plus A, one pump will stop and the other continue until the float reaches the high point of distance D. Both pumps will alternate between the distance C plus D. These devices use graphite coated asbestos packing and are limited to 50 P.S.I. tank pressure.
