Refer to the Purge Samplessection for more information.Purge SamplesIf the component weight of a full stroke purge sample islow, perform the following:1. Look for material leaking from the system.2. Thoroughly inspect the system to pinpoint andeliminate leaks.If the component weight of a full stroke purge sample ishigh, perform the following:1. A leaky inlet valve may be allowing material to flowthrough during the purge, rather then metering it.Check the inlet valve and its solenoids for properoperation. Replace these parts if necessary.2. If you suspect that air is trapped inside the meteringcylinder, evacuate the air by running the entiresystem until it delivers a continuous flow of material.NOTE:The system cannot be bled. Trapped airmust be pumped through the system and outof the SDS meter. Material passages in thecylinder aid in evacuating trapped air.3. If the results are still not within the limits, contact yourNordson representative.Shutdown1. Turn off and bleed the pressure from the Rhinounloader pumps.
