Phase-Limit Fault
Problem Solution
This fault occurs when a
phase limit has been reached
during a learn phase or
automatic phase period. It
may be caused by
contaminated product or
metal elsewhere in the
system. If necessary, check and adjust the phase limits.
Check for contaminated product and metal
elsewhere in the system.
QA Test Response Fault
This type of fault only occurs in conveyor applications.
Problem Solution
The QA test light has been
ignored and the interval timer
has expired. Perform a QA test.
QA Test Result Fault
Problem Solution
During the QA test, the
required number of detections
of a specific peak size did not
occur. Repeat the QA test so the required number of
detections are achieved.
AuditCheck Fault
This fault only occurs if the optional AuditCheck hardware is installed on your APEX and
you are using the detector’s AuditCheck capabilities to monitor performance.
Problem Solution
This fault occurs during an
AuditCheck timed calibration
and indicates that there is
problem with the signal
produced by the AuditCheck
metal ball as it passes through
the search head with your
product. Make sure that you have set up appropriate fault
limits for the AuditCheck function, because the
signal produced by your product will vary. Also,
verify that the Alarm Limit and Fault Limit have not
been inadvertently misapplied.
