Issues
Possible Causes
Solutions
The inFlow™ ACE is not actuating
properly.
The hydraulic supply may be too low or
not operating.
The pneumatic supply may be too high,
too low, or not operating.
The solenoid may not be operating
properly.
Inspect the electro-hydraulic unit (EHUC).
Add hydraulic oil as necessary. If the
EHUC is not operating, refer to the
Installation, Operation, and Maintenance
(IOM)
Manual
for the EHUC.
Inspect the pneumatic supply and
regulator to ensure that air is supplied at
the appropriate pressure.
Use the manual override button on the
solenoid and ensure proper operation. If
the solenoid is operating improperly, refer
to the
Installation, Operation, and
Maintenance
(IOM)
Manual
for the
solenoid.
The sample container is not filling.
The inlet valve on the sample container
may be closed.
The outlet on the sample container may
be open.
The inFlow™ ACE is not collecting the
correct sample volume.
The inFlow™ ACE may be set at a slower
sampling frequency than desired.
The relief on the inFlow™ ACE may be set
too high.
Ensure that the sample inlet valve on the
sample container is open during
sampling.
Ensure that the sample outlet valve on the
sample container is closed during
sampling.
Welker recommends the Welker
Checkpoint™ Sample Bite Verification
Panel for verifying the sample volume of
the inFlow™ ACE. See
for instructions on
adjusting the sample volume.
Adjust the inFlow™ ACE to sample at the
desired rate. Ensure that the calculations
used to determine the sample frequency
are correct (
).
Check the setting on the relief and adjust
as necessary.
