Solutions
Refer to Figure 8 to determine the
appropriate setting for the supply. 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 (Figure 8).
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.
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 inLoop™ ACE. See Section 2.2,
Installing the Unit, for instructions on
adjusting the sample volume.
Adjust the inLoop™ ACE to sample at the
desired rate. Ensure that the calculations
used to determine the sample frequency
are correct (Figure 9).
