ALARMS
There are two types of alarms generated in the 360a Applicator:
Warning Alarm
Critical Alarm
Warning Alarm Status Box Critical Alarm Screen
Warning Alarms will appear in the upper right hand corner of the Main Menu in the Status Box. Since
these alarms are not serious, the Applicator will not be stopped. During a Warning Alarm, the amber light
on the Light-Stack (if provided) will be turned on.
Critical Alarms will stop the Applicator (take it offline) and turn a red light on in the Light-Stack (if
provided). The Alarm Screen will cover the current screen explaining the alarm type. An Alarm Reset
button appears at the bottom of the page to clear the alarm.
Warning Alarms
The following are Warning Alarms monitored by the Applicator:
Inhibit – This alarm occurs when an external device inhibits the Applicator from dispensing a label by
activating the Inhibit Input on I/O Connector C2-12.
Tight Loop - If the Loose Loop Option is on and the Alarm Prox (upper Prox) turns on, this alarm occurs
causing the Applicator to stop applying labels until the Lower Prox turns on. There is no Reset Button
for this alarm since the Loose Loop Program controls whether the Applicator is functional or not.
Although the Applicator is stopped, this is still considered a Warning Alarm since the Applicator will
resume labeling as soon as the Printer catches up with the Applicator. The Tight Loop Status Box will
have a red background instead of yellow to signal the alarm condition.
Low Label – This alarm occurs when the Low Label Sensor detects that the unwind roll is nearly out of
labels.
Multi-Label C-C Distance Is Too Low – This alarm occurs when the Multi-Label Option is on and the
Applicator cannot place labels at the desired Center-line Distance. If the application permits, increase
the Label C-C Distance to correct the problem. For Non-Merge Applicators, you can try increasing the
Web Speed value or decreasing the conveyor speed value. In Tamp Applicators, reduce the Tamp
Extend/Retract Times to the minimum. In Air-Blow Applicators, reduce the Air Blast Time to the
minimum and increase the Pre-Dispense Time if possible. In Merge applications contact the factory
concerning appropriate Accel and Decel values for your application.
DAT Label Placements Are Too Close – If the Applicator Type is a Dual Action Tamp and the Second
Label Placement is low enough that the second label is not out onto the Pad before it should be applied,
this alarm will occur. Increasing the Second Label Placement will correct the problem. This also
could be viewed as a rate alarm.
Conveyor Speed, Profile or OverSpeed % Too High Compared To MaxSpeed - This alarm occurs on
Merge Encoder-Based Applicators when the conveyor speed or the product of conveyor speed times
the Profile or Over Speed % yields a speed greater than MaxSpeed. If possible, decrease the conveyor
speed or increase the Applicator’s MaxSpeed value. In Over Speed or Profiling applications try
decreasing the Pre-Apply Speed % or WebRatio % values respectively.
