Overview
Overview
System Description
Each tandem supply system consists of two air-powered
rams. Each ram drives a Check-Mate pump and a platen
into a drum of material. The pump removes material
from the drum and pushes it through a supply hose to a
customer-supplied header. Material flows through the
header to individual dispense drops.
When one drum is emptied the system performs an
automatic crossover, shutting off the air supply to the
pump on the empty ram and activating the pump on the
full ram.
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 19.
Ram Installation
Install the rams as explained in manual 312371, supplied. See also F
over systems) and F
crossover systems).
IG. 2 on page 11 (for pneumatic cross-
IG. 3 on page 14 (for electronic
Grounding
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
Pump: use ground wire and clamp (supplied). Loosen
grounding lug locknut and washer. Insert ground wire
end into lug slot and tighten locknut securely. Connect
ground clamp to a true earth ground.
Air and fluid hoses: use only electrically conductive
hoses with a maximum of 500 ft. (150 m) combined
hose length to ensure grounding continuity. Check electrical resistance of hoses. If total resistance to ground
exceeds 29 megohms, replace hose immediately.
Air compressor: follow manufacturer’s recommendations.
Dispense valve: ground through connection to a prop-
erly grounded fluid hose and pump.
Fluid supply container: follow local code.
Fluid Filter Kit Installation
Solvent pails used when flushing: follow local code.
Some systems include a fluid filter kit. See Fluid Filter
Kit Dimensions on page 32. Ensure that the fluid filter
stand base is level in all directions. If necessary, level
the base using metal shims. Secure the base to the floor
using anchors that are long enough to prevent the filter
stand from tipping.
312395D 9
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive sur-
face, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the dispense
valve firmly to the side of a grounded metal pail, then
trigger the valve.
Overview
Integrated Air Controls
The integrated air controls include:
• Main air slider valve (BA): turns air on and off to
the system. When closed, the valve relieves pressure downstream.
BF
• Ram air regulator (BB): controls ram up and down
pressure and blowoff pressure.
• Ram director valve (BC): controls ram direction.
• Exhaust port with muffler (BD)
• Air motor regulator (BE): controls air pressure to
motor.
• Air motor slider valve (BF): turns air on and off to
the air motor. When closed, the valve relieves air
trapped between it and the air motor. Push the valve
in to shutoff.
• Blowoff button (BG): turns air on and off to push
the platen out of an empty drum.
The air solenoid (Y, FIG. 3), the air motor slider
valve (BF), and the main air slider valve (BA) must
be open for air to flow to the air motor.
• Air relief valve (not visible, attached to ram air reg-
ulator): automatically relieves excessive pressure to
the pump.

System Components (Pneumatic Crossover)
FIG. 2. shows a pneumatic crossover system. Refer to
manual 312371 (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 continuous 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.
