Improve the pack pitch.
If the reject is a retracting band or lift/drop flap, change the reject mode to pulse extension.
■
Problem:
Reject disabled - the reject relay has been manually disabled.
O
Action:
Enable the reject relay using the Reject enable command.
■
Problem:
Calib-in-run abort - a signal that has exceeded the currently set value for maximum
threshold in the learn setup menu has been exceeded during a learn cycle.
O
Action:
Product used for learn is probably contaminated. Select an alternative product for
learning.
■
Problem:
Drive overload - (IQ3 detectors only) this is a warning message advising that the
drive current for the selected operating frequency has increased and is approaching the upper
limit. If the upper limit is exceeded, this will cause the transmitter to operate in 100kHz safe
mode. If safe mode is entered, then the detector operation will be affected and may cause false
rejects or poor metal sensitivity.
O
Action:
Go to the VF drive menu and select the same frequency that was running when
the error occurred. It may be that the drive ON time has been manually increased.
Decrease the value of the ON time entry incrementally, until the displayed drive current (in
the same menu) is in the region of 230 - 250mA. Note that detectors with large apertures
will have drive currents below the normal 230 - 250mA range if operating at frequencies
above 650kHz. If the message persists or the user is in doubt then contact your local
Loma Service Centre for assistance.
System Faults Log
Purpose
System faults are classified as serious and require immediate action. When a fault is generated the
fault relay operates, permanently operating the reject device and/or stopping the conveyor transport.
This log is useful for monitoring the types of faults being generated that interrupt production and
looking for potential trends so that improvements may be made to reduce production down time.
Selecting the System Faults Log option in the
Logs/Reports
screen displays the System Faults Log
screen.
Screen Contents
The screen displays a list of system faults under the following column headings:
■
Date
– Displays the date that the error occurred.
