Frequently Asked Questions - PROMIX 2KS GRACO

What types of paints can the ProMix 2KS mix?

The ProMix 2KS can mix most two-component paints: epoxy, polyurethane, acid-catalyst varnish, solvent-based or water-based, as well as moisture-sensitive isocyanates. It is not suitable for fast-drying paints (pot life less than 15 minutes).

How to set the mix ratio on the device?

In the Recipe configuration screen, use the EasyKey keypad to enter the desired ratio (from 0.1:1 to 50:1) and tolerance (1-99%). The ratio is displayed in real time on the status screen.

What is the depressurization procedure before maintenance?

Follow the procedure described in the manual: cut off power supply, close air inlet, trigger the gun to release pressure, open discharge valves if present. Never point the gun at a person.

How to calibrate flow meters?

Access the Calibration screen on the EasyKey. Select flow meter A, B, or solvent. Start calibration in mix mode; the system automatically adjusts the K factor. Then use the sample valve to verify the dosage.

What to do in case of low ratio alarm (E-4)?

Check restrictions in the system (clogged nozzle, improperly adjusted valve), equalize A and B supply pressures, and ensure metering valves function correctly. If alarm occurs at startup, shorten the gun pointer stroke.

Can the system be used in manual mode?

Yes, by setting Run mode to 'Manual' in Configure screen 3. In this mode, the user controls triggering via the gun trigger. A manual control screen allows selecting standby, mix, flush, or recipe change modes.

How to perform a color change?

Activate the 'Start Color Change' input (minimum 100 ms). The system automatically executes flush and fill sequences. Monitor the 'Purge_CC_Active' and 'Fill_Active' outputs on the I/O panel. The mix bit configuration must be loaded before activation.

What accessories are available for the ProMix 2KS?

Optional kits are offered: third flush valve, solvent start switch, extension cables (power, fiber optic), integrators of various sizes (10, 25, 50, 100 cc), strobe alarm indicator, Ethernet/DeviceNet/Profibus communication gateways, advanced Web interface.

How to clean the system after use?

Use the flush function: activate the flush input or manually select Flush mode. The system rinses the lines with air and solvent (or a third flush valve) according to programmed sequences. Always follow the depressurization procedure before cleaning.

Where to find part numbers and related manuals?

The configured part number is printed on the equipment identification label (EasyKey or fluid station). Related manuals include: installation (312778), repair-parts (312780), mixing manifold (312781), dispensing valve (312782), color change valve block (312783), etc. Downloadable from the Graco website.
