Graco Plural Component Proportioner MD1232

Warning: Wear eye protection to avoid splashing fluid in the eyes.

The fluid shutoff valves and ratio check valves are retained by mechanical stops that prevent accidental removal of the valve stem while the manifold is pressurized.

If you cannot turn the valve stems manually, relieve the system pressure, then disassemble and clean the valve to remove the resistance.

Calibrate the meter: The first time the system is operated, whenever new materials are used in the system, at least once per month as part of regular maintenance, whenever a flow meter is serviced or replaced.

K-factors on the Calibration Screen are updated automatically after the calibration procedure is completed.

K-factor values on the screen are viewable only. If needed, you can manually edit the K-factors in Advanced Setup Screen 4 or Recipe Setup Screen 5.

All values on this screen are in cc, independent of the units set in Configure Screen 1.

The controller will use the active recipe K-factors for meter calibration. The active recipe must be recipe 1 to recipe 60. Recipes 0 and 61 do not have K-factor values.

Before calibrating meter A or B, prime the system with material. For a color/catalyst change system, make sure the color/catalyst valve is open.
