Maintenance and Troubleshooting
Cause
Occurs if during a QA test the
required number of detections of
Fault
specific peak size did not occur.
Cause
Occurs only if the excess reject
Fault
fault has been turned on and the
excess reject parameters
programmed. The fault indicates
an excessive amount of rejects
have occurred within the
specified time window.
Cause
Occurs if a phase limit has been
reached during a learn phase or
automatic phase period. May be
caused by contaminated product
or metal elsewhere in the system.
Cause
Fault
This fault indicates an excessive
block time for the
which is probably due to
eye misalignment.
Fix
Enter QA test mode and repeat the test to
achieve the required number of
detections.
Fix

Note: This fault may be caused by
excessive contamination in the product. The
rejected product should be examined to
confirm this and appropriate action taken.
Fix
If necessary, check and adjust the phase
limits.
Fix
