By using the Continuous Cycle Mode of the controller, the cylinder will continually cycle between the two
set point limits. In this case, there will be 8" of piston travel in each direction to perform the desired task.
FIGURE 20 illustrates the output actions and the ideal voltage output versus piston travel (seen at Ter-
minals 6 and 7). Control potentiometer 1 is used to set the inner limit (2") and control potentiometer 2
is used to set the outer limit (10"). Relay 1 will be on while the cylinder is retracting to the inner limit (2").
When the piston reaches the inner limit, Relay 1 will shut off and Relay 2 will be energized. Relay 2 will
cause the cylinder to extend until the piston reaches the outer limit (10"), where Relay 1 will turn on and
the process will repeat.
