Graco 3A2098H Ground, Connect Fluid and Air Lines, Air and Fluid Hoses, Dispense Valve

Ground

To reduce the risk of fire, explosion, or electric shock, when grounding, connecting cables, connecting to a power source or making other electrical connections:

•The control center must be electrically connected to a true earth ground; the ground in the electrical system may not be sufficient. Refer to your local code for the requirements for a “true earth ground” in your area.

•All wires used for grounding must be 18 AWG min- imum.

•A qualified electrician must complete all grounding and wiring connections.

•For 24 Vdc wiring refer to FIG. 13.

•For 100-240 Vac wiring refer to FIG. 14.

•Incoming power wiring must be guarded from the enclosure. Use a protective grommet where the power wiring enters the enclosure to prevent wear.

NOTICE

If power and grounding connections are not done properly, the equipment will be damaged and the warranty voided.

Ground the fluid plate assembly as instructed here and in the individual component manuals. Make sure the fluid plate assembly and its components are installed correctly to ensure proper grounding.

Air and Fluid Hoses

For static dissipation, use only electrically conductive hoses or ground the applicator / dispense valves.

Dispense Valve

Follow the grounding instructions in the dispense valve manual.

Installation

Connect Fluid and Air Lines

NOTICE

Route all fluid and air lines carefully. Avoid pinching and premature wear due to excessive flexing or rub- bing. Hose life is directly related to how well they are supported.

Follow the instructions in your separate component manuals to connect air and fluid lines. The following are only general guidelines.

•The PCF fluid plate assembly should be installed on the automation unit or in another appropriate place, as close as practical to the dispense valve.

•Connect a fluid line between the fluid plate outlet and the dispense valve. Smaller diameter and shorter fluid lines (hoses) will provide better fluid system response.

•Connect a fluid line to the flow meter fluid inlet or to the regulator inlet if your system does not have a flow meter.

•Air must be clean and dry, between 60-120 psi

(0.41-0.82 MPa, 4.14-8.27 bar). Flush air line before plumbing in air filter assembly (234967). Plumb in air filter assembly near air drop site (upstream of fluid plate module). Adding an air regulator to this line will provide more consistent dispense valve response times.

•Connect an air supply line to the 1/4 npt inlet port on the fluid plate(s) air supply inlet.

•Connect 5/32 in. or 4 mm OD air lines from the appli- cator's solenoid valve to the applicator. Plug any unused solenoid ports.

NOTE: To maximize system performance keep the dis- pense hose length and ID as small as the application will allow.
