Example Problems
Some example system faults problems that may be displayed and suggested remedial actions are
listed below.
■
Problem: 5V out of spec - the 5V rail is less than 4.75V.
O
Action: Contact your local Loma service centre for assistance.
■
Problem: +12V out of spec - the +12V rail is less than 11.40V.
O
Action: – Contact your local Loma service centre for assistance.
■
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.
