Fault and Error Diagnosis
Module 6022
4-4
System Faults
Are classified as fatal and require immediate action. When an error is generated the
fault relay operates, permanently operating the reject device and/or stopping the
conveyor transport. In addition the Fault Relay LED
"
"
"

on the User Interface
illuminates. If your detector is fitted with the Reports/Logs package the faults can be
accessed in the System Fault menu "View faults". All faults are described as either
passive (PSV), active (ACT) or as an event (EVT) the date & time accompany errors.

1. Check the head cable is
properly seated in PL1 on the
control board.
2. Check OSGO DC voltage as
described in
on page 5
in
the “Functional Testing” section
of this manual.
5v out of spec
5v rail is less than 4.75v
1. Check 5v rail as described in
on page 7
the
“Functional Testing” section of
this manual.
+12v out of spec
+12v rail is less than 11.40v
1. Check +12v rail as described

+Powered up+
Logged every time the system is
powered up.
No action required.
Verdict too late
A pack has arrived at the reject
point before the detector has
sent a reject decision.
1. Increase the reject delay time.
2. If in PEC Mode, reduce the
pack length.
Verdict mismatch
The system has more reject
verdicts than packs passed.
1. Power machine off and on.
Rej confirm fail
The reject system has attempted
to reject a pack but could not
confirm that the pack was
removed from the line, within the
specified time.
If the pack has been correctly
rejected:
1. Check the Reject confirm
sensor is working.
2. Check the Reject confirm
timing parameters are correct.
Rej con wind fail
The reject confirmation system
has received two packs in one
reject confirm window.
1. If 2 packs were supposed to
be rejected than reduce the
Reject confirm window.
2. Reduce the Reject dwell time.
