XM Setup and Tips
62 312359R
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.
• If a minimum of integration and mix hose is used,
ensure that “Fast Dosing” is selected in the setup
screens
Software Version
• Ensure all modules in the system use software from
same token. Different software versions may not be
compatible.
• The latest software version for each system can be
found at Tech Support at www.graco.com.
