tem. Use the following matrix to define the construction of the supply system,
based on the six digits. For example, Part No. CM14BA represents a
Check-Mate supply system (CM), a carbon steel Check-Mate 100 MaxLife®
displacement pump with an NXT 2200 air motor with remote DataTrak (pump
code 14), a 3 in. dual post ram with integrated air controls (B) and a 55-gallon,
uncoated platen with a neoprene seal (A).
To order replacement parts, see Parts section in manual 313527. The digits in the matrix on the next page do not
correspond to the Ref. Nos. in the Parts drawings and lists.
All supply systems with DataTrak and 24 Vdc or 100-240 Vac power supplies are ETL approved.

The integrated air controls include:
• Main air slider valve (BA): turns air on and off to
the system. When closed, the valve relieves pres-
sure downstream.
•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. Remote DataTrak: The air solenoid
(X, FIG. 1), the air motor slider valve (BF), and the
main air slider valve (BA) must be open for air to
flow. (See Remote DataTrak Setup, page 23.)
•Blowoff button (BG): turns air on and off to push
the platen out of an empty drum.
Air Line Accessories
See FIG. 1.
• Air line drain valve (U)
•Air line filter (V): removes harmful dirt and mois-
ture from compressed air supply.
•Second bleed-type air valve (W): isolates air line
accessories and supply system for servicing. Locate
upstream from all other air line accessories.
•Air relief valve (attached to ram air regulator, not
visible): automatically relieves excessive pressure.
2-Button Interlock Air Controls
D60i, D200i, and D200si Models
Units that have 2-Button Interlock controls have the fol-
lowing additional components:

Air and Fluid Hoses
Be sure all air hoses (T) and fluid hoses (S) are properly
sized and pressure-rated for your system. Use only
electrically conductive hoses. Fluid hoses must have
spring guards on both ends. Use of a short whip hose
and a swivel between the main fluid hose and the
gun/valve allows freer gun/valve movement.

General Information
Accessories are available from Graco. Make certain all
accessories are adequately sized and pressure-rated to
meet the system’s requirements.
FIG. 1, FIG. 2, and FIG. 6 are only guides for selecting
and installing system components and accessories.
Contact your Graco distributor for assistance in design-
ing a system to suit your particular needs.
Location
Attach a lifting sling at the proper lift spots. Lift off the
pallet using a crane or a forklift.
Position the ram so the air controls are easily accessi-
ble. Ensure that there is enough space overhead for the
ram to raise fully. (See Dimensions, page 34.)
Using the holes in the ram base as a guide, drill holes
for 1/2 in. (13 mm) anchors.
Ensure that the ram base is level in all directions. If nec-
essary, level the base using metal shims. Secure the
base to the floor using 1/2 in. (13 mm) anchors that are
long enough to prevent the ram from tipping.
Grounding
Pump: use a ground wire and clamp. Loosen grounding
lug locknut and washer. Insert one end of supplied
ground wire into slot in lug and tighten locknut securely.
Connect other end of wire to a true earth ground. See
FIG. 8.
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 elec-
trical resistance of hoses. If total resistance to ground
exceeds 29 megohms, replace hose immediately.
Air compressor: follow manufacturer’s recommenda-
tions.
Spray gun/dispense valve: ground through connection
to a properly grounded fluid hose and pump.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code.
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.
Reference numbers and letters in parentheses in
the text refer to the callouts in the figures.
NOTICE
Always lift supply system at proper lift locations (see
FIG. 1, FIG. 2, and FIG. 6). Do not lift in any other way.
NOTICE
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by provid-
ing an escape wire for the electrical current due to
static build up or in the event of a short circuit.

Mechanical Setup
1. Fill displacement pump wet cup 2/3 full with Graco
Throat Seal Liquid (TSL).
2. Back-off air regulators to their full counterclockwise
position and close all shutoff valves.
3. Connect air line from an air source to the system air
inlet. See FIG. 1 or FIG. 2. Refer to the pump perfor-
mance curves in manual 312376 to determine your
air supply flow requirements. Use a supply hose
capable of meeting the required flow.
Connect Remote DataTrak to Power
100-240 Vac
The system has an IEC-C14 power input connection
located on the back of the power supply box. The user
must supply an appropriate adapter. The 100-240 Vac
supply must be capable of sourcing at least 1.2 Amps
and have supply current protection rated in accordance
with the supply wire gauge provided.
Have a trained electrician install and inspect power con-
nection per local code. Plug power supply cord into the
outlet on the back of the power supply box and into a
properly grounded electrical outlet. Use a zip tie, if
needed, to secure power cord in place.
24 Vdc
Attach 24V Class 2 power supply to terminals on the
24V assembly: +24 Vdc to terminal 2 (+) and -24 Vdc to
terminal 5 (-). Attach protective earthing (PE) conductor
to terminal marked .
The 24 Vdc supply must be capable of supplying at least
1.2 Amps and have supply current protection rated at no
more than 2.5 Amps.
Have a trained electrician install and inspect power con-
nection per local code.
Quick disconnects restrict flow for large air motors.

Attach and Adjust Drum
Low/Empty Sensor
For supply systems with remote DataTrak, an optional
kit can be purchased to indicate either when the drum is
low or when it is empty. Order kit 255469 for a D60 or
D200 3 in. ram, 255689 for a D200s 6.5 in. ram, or
257634 for a S20 3 in. ram.
1. Position ram at desired level (low or empty).
2. Attach low/empty sensor bracket (EA) to mounting
bracket (EB).
3. To measure either drum low or drum empty, attach
one sensor (EE) to the sensor bracket (EA).
4. For D60, D200, and D200s supply systems: Attach
the actuator (ED) to the ram piston rod, near the top,
so it passes in front of the sensor (EE) at the correct
level for drum low or drum empty. See FIG. 9.
5. For S20 supply systems: Attach the actuator (ED) to
the ram cylinder endcap, so the sensor (EE) passes
in front of the bracket (ED) at the correct level for
drum low or drum empty. See FIG. 10.
6. Make precise adjustments by moving the sensor
within the slot on the sensor bracket.
7. Attach the sensor to the corresponding connector
on the D-Sub harness of the remote DataTrak.

a. Close the air motor valve (DC) and the elevator
director valve (DD). The ram will slowly drop.
4. Unlock the gun/valve trigger.
5. Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail, and trigger the gun/valve
to relieve pressure.
6. Lock the gun/valve trigger.
7. Open the fluid line drain valve and the pump bleeder
valve (P). Have a container ready to catch the drain-
age.
8. Leave the pump bleeder valve (P) open until ready
to spray again.
If you suspect that the spray tip/nozzle or hose is com-
pletely clogged, or that pressure has not been fully
relieved after following the steps above, very slowly
loosen the tip guard retaining nut or hose end coupling
and relieve pressure gradually, then loosen completely.
Now clear the tip/nozzle or hose.
Flush Before Using Equipment
The pump was tested with lightweight oil, which is left in
the fluid passages to protect parts. To avoid contaminat-
ing fluid with oil, flush the pump with a compatible sol-
vent before use. See pump manual for flushing
directions.
