5.0 Appendix
5.1 Error Messages
The following error conditions are explained below.
5.1.1 Weigh Hopper Overfill
Weigh hopper overfill is detected if either the weigh hopper or high bindicator goes off or the scale weight exceeds
the overfill weight preset during a fill cycle or at the start of a sequence.
It can also be detected if the weight increases after resuming after a weigh hopper overfill.
The operation is paused if this condition is detected before or during a fill operation. If this condition is detected
during the sequence, it is recorded on the printed record.
5.1.2 Lower Surge Backup
Lower surge backup is detected if the lower surge or high bindicator goes off during the discharge cycle or it is off
at the start of the sequence.
The operation is stopped if this condition is detected before or during a discharge operation. If this condition is
detected during the sequence, it is recorded on the printed record.
5.1.3 Printer Error
The printer error condition is detected if an attempt is made to print data and the printer is either offline or in an
error status that will not allow printing. The operation will be stopped.
The operation is paused if this condition is detected. If this condition is detected during the sequence, it is recorded
on the print record when the ability to print is restored.
5.1.4 Gate Error
The gate error condition is detected if:
• Either gate is open when the sequence is started.
• The fill gate does not close within the specified delay after fill time.
• The discharge gate does not close within the specified delay after discharge time
• The discharge gate closed signal goes off during a fill operation.
• The fill gate closed signal goes off during a discharge operation.
5.1.5 Error Recovery
On entry to the stopped state, the fill and discharge outputs are set to off and all error conditions are checked.
Once in stopped state, the system remains stopped until all error conditions are cleared (all gate closed signals are
on, the printer is online, and the lower surge not high signal is on). At that point the system enters into a paused
state.
On entry to a paused state, the fill and discharge output are set to off. Press the Start/Resume button or the Resume
softkey on the display.
All detected errors are printed along with their detected date and time.
If the resume was following a weigh hopper overfill error, the system resumes at step 9 in System108 instructions
or step 7 in System 107 instructions. All other resumes will be at the step they were recognized in.
