Fig. 5. Sequential operation of three motors with Q7230A
Interface Module.
11. Recheck the fully open position and readjust the span
potentiometer, if necessary. (Turn the span potentiome-
ter clockwise to close the motor, counterclockwise to
open the motor.)
12. For sequential operation at two or more motors (as
shown in Fig. 5), repeat the above steps for each motor,
individually adjusting each for the desired response to
the input signal.
