(WARNING ALARMS)
Label Placement is Too Low
– This alarm occurs in Encoder-Based applications when the Label Placement
distance is too small for encoder compensation to work correctly. During label placement a speed
dependent distance is subtracted from the label placement value to properly position the label. If this
alarm occurs, move the Product Detect Sensor upstream more, decrease the conveyor speed, or
increase the Label Placement value.
Profile Or OverSpeed % Too High Compared To MaxSpeed – This alarm occurs in Merge Time-Based
applications when the Profiling or Over Speed % times the Web Speed value yields a speed greater
than the MaxSpeed. If possible, decrease the conveyor speed or increase the Applicator’s MaxSpeed
value. If possible, decrease the Over Speed Pre-Apply Speed % or the profiling WebRatio % values.
Imprint Dwell Too High For Label Cycle – This alarm occurs if the Imprinter Valve is on when the
Applicator is ready to dispense a label to the product, Air-Blow Grid, or Tamp Pad. For Merge
applications, no label will be dispensed. Air-Blow and Tamp Applicators will wait for the Imprint
Dwell to timeout before dispensing a label to the Grid or Pad.
Critical Alarms
The following are the critical alarms monitored by the applicator:
End Of Web – This alarm occurs when the End Of Web sensor detects a break in the web.
No Labels Found – This alarm occurs if the number of consecutive missing labels on the liner exceeds the
Missing Label Count value. If a No Labels Found Alarm occurs when labels are present on the liner,
re-teach the label sensor sensitivity settings.
Printer Not Ready - This alarm occurs when the Printer is paused while the Applicator is controlling a
Printer in a Loose Loop format with the Printer Ready Input Signal active.
CHANGING VALUES
Values that may be changed are shown in boxes displaying the current value. In the example below, label
length is shown to have a value of 1.75”. To change this value, the operator will touch the screen in the
label length field and a keypad will appear to the side of the variable being changed. The figure to the right
shows what the Display should look like after touching the variable field. You can see a cursor has moved
over the rightmost digit. Also the numeric keypad has appeared to the left of the variable. As you touch
numbers on the keypad, the variable is zeroed and the new value is input to the variable box. Pressing
“ENT” will finish the process. Pressing “ES” will allow you to escape without changing the value and
“CR” will clear the value you’re changing.
Note: In most cases, an out-of-range value will not produce
a warning message but the variable will return to the original value after pressing “ENT”.
