
Problem – Verdict too late - a pack has arrived at the reject point before the detector has
sent a reject decision.
o
Actions:
1. Increase the reject delay time.
2. If a product registration photo-eye is installed, reduce the pack length.

Problem: Verdict mismatch - the system has more reject verdicts than packs passed.
o
Action: Power machine off and on.

Problem: Rej confirm fail - the reject system has attempted to reject a pack but could not
confirm that the pack entered the reject bin and was removed from the line, within the
specified time. When this fault occurs, the conveyor should be cleared before the transport
can be restarted.
o
Action:
If the pack has been correctly rejected:
1. Check the reject confirmation sensor is working.
2. Check the reject confirmation timing parameters are correct.
If the pack has not been correctly rejected, the transport system will have stopped:
1. Collect and remove from the line all product/s both in the aperture and after the
detector. If there is any possibility that the contaminated product may have left the
detector transport system, then any possible contaminated product beyond the detector
transport will need to be cleared as well. It is advised that any removed product be
properly identified and securely segregated from good product.
2. Recheck the setup parameters and the function of the reject and confirm systems
before restarting the line.

Problem: Rej con wind fail - reject confirm window failure. The reject confirmation system
has detected two packs in one reject confirm window.
o
Actions:
1. Check for the possibility of a single pack double triggering the reject confirmation
photo-eye.
2. If two packs were supposed to be rejected than reduce the Reject confirmation
window time.
3. Reduce the reject dwell time.

Problem: Confirm sensor fault - the reject confirm sensor has been blocked for greater than
the Reject confirmation timeout.
o
Actions:
1. Check the sensor for blockage.
