INSTALLATION AND OPERATIONCROSS-OVER CONTROLLER INSTALLATION ON RAMS
Install Cross-Over Controller assembly (67448) for
RM552H-XXX-XX, RM552 S-XXX-XX, RM052S-XXX-XX and
RM072S-XXX-XX Rams. (see Figures 5 & 7, pages 4 & 6).
a. Remove the two Cap Screws (96719) that hold the
Rotary Lever Valve (M512LR) to the Ram.
b. Place Cross-Over Controller assembly behind Rotary
Lever Valve and reattach the Rotary Lever Valve using
the two Cap Screws.
c. Repeat steps a-b for second Ram.
2. Install Cross-Over Controller assembly (67449) for
RM051S-XXX-XX Ram (see Figures 6 & 7, page 5 & 6).
a. Remove the Cap Screws (96702170) and Washers
(96756) that are on the Ram.
b. Attach Cross-Over Controller assembly to Ram using
(17) Cap Screws and (16) Washers.
c. Repeat steps a-b for second Ram.
3. Low Level Cutoff Kits (67500, 67501 or 67502) are re-
quired to make Cross-Over operational. Attach a Low Lev-
el Cuto to both Rams, using instructions in the manual
for the Low Level Cuto kit.
4. Remove both Tubing’s (94981-XXX-X) from the Low Level
Cuto on each Ram and discard.
5. Using (94981-XXX-X) Tubing. Attach Tubing to Port #2 on
the Limit Valve Assembly (402-A) of the Low Level Cuto.
Run Tubing to (8) “Y” Connector at pilot port closest to
port #1 on (2) Valve. Cut to length and attach to the “Y”
Connector. Approximant length of Tubing is 48 inches.
Repeat for second Ram.
6. Using (94981-XXX-X) Tubing. Attach Tubing to pilot port
on top of Valve (H254PS) closest to Port #3 of the Low
Level Cuto. Run Tubing to (7) Branch Connector at port
#1 on ( 2) Valve. Cut to le ngth and attach to the Branch
Connector. Approximant length of Tubing is 45 inches.
Repeat for second Ram.
7. Using (94981-XXX-X) Tubing. Attach Tubing to pilot port
on top of Valve (H254PS) closest to Port #2 of the Low
Level Cuto. Run Tubing to (9) Male Elbow at port #2 on
(2) Valve. Cut to length and attach to the Male Elbow.
Approximant length of Tubing is 45 inches. Repeat for
second Ram.
8. Using (94981-XXX-X) Tubing. Attach Tubing to (8) “Y” Con-
nector at pilot port closest to port #1 on (2) Valve on the
first Ram. Run Tubing to (7) Branch Connector at pilot
port closest to port #3 on (2) Valve on the second Ram.
1.
Cut to length and attach to the Branch Connector.
9 Using (94981-XXX-X) Tubing. Attach Tubing to (7) Branch
Connector at pilot port closest to port #3 on (2) Valve on
the rst Ram. Run Tubing to (8) “Y” Connector at pilot port
closest to port #1 on (2) Valve on the second Ram. Cut to
length and attach to the Branch Connector.
10. No tubing will be connected to port #3 on the Limit Valve
Assembly (402-A) of the Low Level Cuto.
11. One Time Only: When all air lines are connected, press
the “Stop” button on each Ram to insure the valves are in
the correct position.
OPERATION
Turn o the air supply to the pumps.
Raise the both R ams and place a drum of material into

The system is now ready for operation.
Press the “Start” button on one of the Rams to start the
pump.
When one drum becomes empty, the other pump will
begin pumping by receiving a signal from the Ram with
the empty drum.
NOTE: Priming operation will be required whenever there
is a drum change.
In order to stop the system, press the “Stop” button on
