User manual GRACO PRO MIX 3KS 313882B

[. . . ] Operation ® ProMix 3KS 313882B ENG Plural Component Proportioner Manual system for proportional mixing of plural component coatings. Approved for use in explosive atmospheres (except the EasyKey and 3KS Power Supply Module). Important Safety Instructions Read all warnings and instructions in this manual. See page 4 for model information, including maximum working pressure. [. . . ] Start with the settings recommended in Mix Manifold Valve Settings, page 48, then adjust as needed. Fluid supply valves open and pressure set Component A, B, and C fluid supply pressures should be equal unless one component is more viscous and requires a higher pressure setting. Solenoid pressure set 75-100 psi inlet air supply (0. 5-0. 7 MPa, 5. 2-7 bar) 2. Turn the AC Power Switch on the EasyKey and on the Power Supply Module ON (I = ON, 0 = OFF). Make sure that the Booth Control is working. The active recipe number should display and the Standby LED should be lit. Graco logo, software revision, and "Establishing Communication" will display, followed by Status screen. At power up the system defaults to Recipe 61, which is not a valid recipe number. Initiate a color change to Recipe 0 or a valid recipe number (1-60). In bottom left corner, the system status displays, which can be Standby, Mix, Purge, or an alarm notification. I = ON 4. If this is the first time starting up the system, purge it as instructed in Purging Fluid Supply System, page 59. The equipment was tested with lightweight oil, which should be flushed out to avoid contaminating your material. Make sure that the Booth Control is in Standby mode. TI12656a TI14372a FIG. Power Switch 50 313882B System Operation 6. Adjust component A, B, and C fluid supplies as needed for your application. Do not exceed the maximum rated working pressure shown on the system identification label or the lowest rated component in the system. Open the fluid supply valves to the system. Most applications require about 80 psi (552 kPa, 5. 5 bar) air pressure to operate properly. Do not use less than 75 psi (517 kPa, 5. 2 bar). If using a gun flush box, place the gun into the box Watch the fluid flow rate displayed on the Status screen while the gun is fully open. Verify that the flow rate of components A, B, and C are within 10% of each other. If the fluid flow rate is too low: increase air pressure to component A, B, and C fluid supplies or increase the regulated fluid pressure.
