Pneumatic Crossover System Components

NOTE:

D200, D60, and S20 sizes are used in pneumatic

crossover systems.

IG. 2. shows a pneumatic crossover system. Refer to

manual 313526 (supplied) for ram installation and oper-

ating instructions. The pneumatic crossover operates as

follows:

During system operation, as the ram approaches the

drum bottom, the top of the ram contacts the limit switch

(E). The limit switch shuts off air to the air motor via a

solenoid valve (Y), which stops air flow to one motor and

starts air flow to the other air motor. This allows continu-

ous material flow and changing of material drums.

The position of the limit switch (E) on the ram deter-

mines when the air motor is turned off. Start by position-

ing the limit switch to trip when the ram platen (D) is 1 in.

(25 mm) from the bottom of the drum. During operation

the position may be adjusted as desired.

The bypass valve (L) allows you to prime the inactive

pump after a drum change. Open the valve to prime the

pump. Close the valve when priming is complete, and

during normal operation.
