Led Diagnostic Information - Graco XM Series Operation

Troubleshooting
Remote Mix Manifold Applications
Ensure remote mix manifold outlet kit is installed. See XM
Repair parts manual. The kit includes outlet check valves
which isolate the pump pressure sensors from the outlet
hoses, and includes a 'B' side restrictor valve for the
machine outlet.
Early remote manifold machines didn't include the 'B'
restrictor valve from the factory.
• Ensure that the 'A' and 'B' outlet hose sizes volume
balanced close to the mix ratio. Unbalanced hose sizes
can cause off ratio slugs at the mix manifold during
pressure and/or flow transitions. See XM Mix Manifold
Kits manual.
