INSTALLATION AND OPERATION
CROSS-OVER CONTROLLER INSTALLATION
ON RAMS
1. Install Cross-Over Controller assembly (67448) for
RM552H-XXX-XX, RM552S-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-B Ram (see Figures 6 & 7, page 5 & 6).
a. Remove the Cap Screws (96702170) and Washers
(96756) that are on the Ram. (Only needed on models
SP0443X2XXXXXXXX and NP322XX4XR7-XX)
b. Attach Cross-Over Controller assembly to upper bolt
pattern of Ram Head (Ref PN 97543-1 on Ram Assem
bly) using (16) Washers, (17) Cap Screws, (18) Lock
Washers, and (19) Nuts (see figure 6, page 5).
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 Cutoff to both Rams, using instructions in the manual
for the Low Level Cutoff kit.
4. Remove both Tubing’s (94981-XXX-X) from the Low Level
Cutoff on each Ram and discard.
5. Remove push-tubing fitting from Limit Valve Assembly
(MQ3863) Port #2 and install tube fitting (59756-56) in Port
#1.
Remove Exhaust Silencer from Limit Valve Assembly
(MQ3863) Port #1 and install in Port #2.
Port #3 to remain open with no tubing connected.
Using (59675-XXX-X) Tubing, attach tubing to Port #1 on
the Limit Valve Assembly (MQ3863) to the Low Level Cut-
off to (15) Reducer attached to Port #1 on (2) Valve. Cut
to length desired, approximately 48 inches (for Two Post
RAM). Can be shorter for Single Post RAM. Repeat for the
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 Cutoff. Run Tubing to (7) Branch Connector at port
#1 on (2) Valve. Cut to length and attach to the Branch
Connector. Approximant length of Tubing is 45 inches
(for Two Post RAM). Can be shorter for Single Post RAM.
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 Cutoff. 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 (for Two Post
RAM). Can be shorter for Single Post RAM. Repeat for sec-
ond Ram.
8. Using (94981-XXX-X) Tubing. Attach Tubing to (8) “Y”
Connector 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.
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 first 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 (MQ3863) of the Low Level Cutoff.
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
1. Turn off the air supply to the pumps.
2. Raise the both Rams and place a drum of material into
position.
3. Lower both Rams into the drums.
4. Press and hold the “Primer” button. This allows you to
prime the pump. This has to be done on both Rams.
5. The system is now ready for operation.
6. Press the “Start” button on one of the Rams to start the
pump.
7. When one drum becomes empty, the other pump will
begin pumping by receiving a signal from the Ram with
the empty drum.
8.
NOTE:
Priming operation will be required whenever there
is a drum change.
9. In order to stop the system, press the “Stop” button on
the Ram that needs to be stopped.
