pressure (10 Bar or
more) at the output of
blue material pump.
Check for blockage
within the red material
flow meter. Verify some
Deviation
pressure (10 Bar or
more) at the output of red
material pump.
Failure of the dispense

Out of material
Solution
Increase restriction in the system
Decrease restriction in the system
Erase learned System Data, found in the setup
screens under calibration
Make sure the material lines are open and have
proper feed pressure
Check to ensure the pressure transducer is properly
installed and all wires are properly connected
Verify pump moves to limits, if problem persists
replace linear position sensor
Check to ensure the linear position sensor is properly
installed and all wires are properly connected
Replace linear position sensor
Re-tighten the sensor and re-calibrate the machine
Verify that incoming ball valves are open
Verify that feed pumps are supplying material
Inspect filter for debris of filler packout and clean or
replace as necessary
Clear blockage
Clear or replace hose as necessary
Check to make sure the dispense valve is properly
configured and connected to the MCM
On the ADM go into the setup screens -> System->
then make sure that the pump type and size are set
(not --)
Fix blockage in the flow meter.
Add restriction in the line or increase the flow.
Fix blockage in the flow meter.
Add restriction in the line or increase the flow.
Ensure the valve has a proper air supply and seals
properly. If not, service the valve as necessary.
Visually inspect the machine and hoses for sign of
leakage. NOTE: This error will display after 2 full
piston strokes so the leak will be substantial.
