FIGURE 22 shows the condition of the output relays during cylinder movement. The cylinder extends
with both relays 2 and 4 on and solenoid 2 and 4 energized. At 6 inches solenoid 2 turns off, removing
the high speed source from the cylinder. The pressure coming from valve 2 is reduced, therefore, the cyl-
inder moves slower between 6 inches and 7 inches. Solenoid 4 remains on until the cylinder reaches 7
inches where it stops. The operation is similar on the retract cycle (using the retract switch and solenoids
1 and 3). Controls 1, 2, 3, and 4 determine the switching positions of relays 1 through 4 respectively. The
panel LEDs correspond to relay operation.
