PJ180 First Setup and Test Dispensing

Use this procedure only when the PJ180 touchscreen matches the MCGS interface shown below. On this version, A Spd and B Spd are separate gram targets for a five-second discharge, and the production A:B ratio is based on weight. Verify each component with a timed weight test, correct only its calibration factor, then restore the mixer and make one controlled waste discharge before testing a product. PJ180 does not need XYZ path programming.

• Use the machine nameplate, delivered configuration, current Robota manual and the resin supplier’s TDS and SDS.
• If your screen does not match the MCGS interface in this tutorial, stop and use the instructions supplied with that machine.
• Prepare the approved A and B materials, separate clean collection cups, a suitable scale, waste container and required PPE.
• Before removing the common mixing tube and blade for separate collection, stop the machine and follow the delivered shutdown and safe-pressure-release procedure. Never remove mixing parts while a pump or mixing motor is running.
• Confirm the cleaning liquid is compatible with the resin and machine materials. Do not copy a temperature, pressure or ratio from another resin.
• Tank stirring and vacuum are optional. A button in a manual does not confirm that the hardware is installed on your machine.

1. Confirm the order-specific power, grounding, air connection and emergency-stop condition before switching on.
2. Check resin levels, tank lids, hoses, seals and outlet condition. Open only the valves required by the delivered configuration.
3. With the common mixing tube and blade safely removed, route A and B into separate clean cups without passing either component through a common mixing chamber or residual mixed material. On the Main Page, keep Anti-Cure off for production setup and keep dynamic mixing off.

4. Confirm that both three-way valves are in the approved open position. Never close a working valve or obstruct the outlet to force pressure through the system.

5. Set the A and B timed-test fields to five seconds. Tare a clean cup, run Timed Disp. A, allow the final drop to settle and record the weight. Repeat for B with a separate clean cup.
6. Compare each measured weight with its own A Spd or B Spd target. If correction is needed, change only the matching A or B calibration factor. A larger factor increases actual delivery; a smaller factor decreases it.
7. Repeat the weight checks until readings are stable for the approved job. Do not change the production ratio to hide a component-delivery error.

8. After the separate readings are confirmed, stop the machine and follow the same delivered shutdown and safe-pressure-release procedure to reinstall the confirmed mixing blade and tube. Then use A+B timed or jog dispensing into a waste cup and run dynamic mixing as required by the delivered setup until the flow is continuous and free of visible air.
9. Do not use the manual’s high-pressure valve-blocking method. If residual air, interrupted flow or abnormal pressure remains after the normal purge sequence, stop and contact Robota.
10. Check clean shut-off, then dispense conservatively onto one level sample. Keep resin inside the intended edge and cure it only under the resin supplier’s approved conditions.

• A and B five-second weights are stable and match the approved job targets.
• The production weight ratio remains the approved resin ratio; it was not used as a calibration workaround.
• Mixed flow is continuous, with no visible air pocket, leakage or abnormal pressure.
• The outlet stops cleanly and the first sample stays inside the intended edge.

• The touchscreen layout differs from the MCGS page shown here.
• The resin ratio, cleaning-liquid compatibility, optional hardware or approved operating condition is uncertain.
• Weights remain unstable, air remains in the system, or pressure, leakage, alarms or unusual noise appears.
• Cured material is visible inside a pump, valve, hose or mixer.
