Check the identification plate (ID) for the 6-digit part number of your tandem system.

To order replacement parts, see Parts starting on page 18.

Each tandem supply kit consists of one single air-powered r components necessary to configure all pneumatic tandem supply system controls. This kit must be added to an identical single ram supply system (identified with the model information) with supply hoses to make up a complete tandem supply unit. This kit is intended only f manual 3A2175). Attempts to integrate with other systems may not be functional and may require additional parts.

Kit Description

Each tandem supply kit consists of one single air-powered ram supply system and supply hose, as well as all

he components necessary to configure all pneumatic

t tandem supply system controls. This kit must be added to an identical single ram supply system (identified with the model information) with supply hoses to make up a complete tandem supply unit. This kit is intended only for use with HFRS systems that include a D200 or S20 supply system (See manual 3A2175). Attempts to integrate with other systems may not be functional and may

quire additional parts.

Keep clear of the inactive ram, as automatic crossover may occur unexpectedly. To repair or adjust the ram, first follow all steps of the Pressure Relief Procedure on page 10.

Overview

Pneumatic Crossover System Components

NOTE: D200, and S20 sizes are used in pneumatic crossover systems.

FIG. 1. shows a pneumatic crossover system. Refer to manual 313526 (supplied) for ram installation and operating 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 determines when the air motor is turned off. Start by positioning 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.

Setup

Ram Installation and Setup

1. Install and set up individual rams as explained in manual provided.

2. Install outlet check valve assemblies on each ram. Refer to page 25.

3. Install pneumatic crossover kits components on each ram.

a. See pilot valve assembly drawing on page 22.

b. Identify and locate the integrated air control

module.

c. Remove the air hose and air fitting from the top

of the integrated air control module.

NOTE: Leave the hose attached to the air motor on the other end

d. Install the pilot valve assembly on top of the

integrated air control module as shown on page

22.

k. Tube the system using the appropriate D200 or

S20 tubing drawing.

NOTE: The table on the drawing shows tubing cut lengths. Using longer tube lengths will require additional tubing (not provided).

4. When tubing is complete, slowly extend rams to the full up and full down positions and take note how the tubing moves.

5. Secure tubing in place with tape or wire ties.

NOTICE

To avoid machine damage and ensure proper operation, verify tubes are not pinched, kinked, or pulled taught where they are secured when the rams are raised or lowered.

e. Install removed fitting from step c into port 1 of

the pilot valve assembly.

f. Remove plug located on the integrated air con-

trol moduel and replace it with a tube fitting. (See item 209 on page 22).

g. Install the crossover valve assembly on the ram

cylinder as shown on page 22. This assembly will be installed on only one ram.

h. See tubing drawing on page 16 (D200 Ram

Tube Connection Diagram) or page 17 (S20 Ram Tube Connection Diagram) for location

of level switch assembly.

i. Install level switch assembly to the top of the

ram cylinder as shown on page 23.

j. Calibrate the switch to trip when the follower is

about 2 in (51 mm) above the ram base.
