Overview

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 elec-

trical resistance of hoses. If total resistance to ground

exceeds 29 megohms, replace hose immediately.

Air compressor: follow manufacturer’s recommenda-

tions.

Dispense valve: ground through connection to a prop-

erly grounded fluid hose and pump.

Fluid supply container: 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.

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 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

(Y, F

IG. 2), the air motor slider valve (BF), and the

main air slider valve (BA) must be open for air to

flow. (See Remote DataTrak Setup section in Supply

Systems operation manual 313526.)

• Blowoff button (BG): turns air on and off to push

the platen out of an empty drum.

Air Line Accessories

See FIG. 2.

• 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.
