Screen Functionality
From the main Diagnostics screen, the individual categories of Options,
Rewind, Drive Module, Sensors, and Pneumatics can be tested. Once
the Diagnostic menu is entered, the warning tower and discrete
outputs will begin to toggle automatically to test these outputs.
The I/O Diagnostic screen will test the inputs and outputs of the
optional Discrete I/O card. If the card is installed, the inputs IN1
through IN4 will display a black background if the signal is active, and
a white background if no signal is present.
The Rewind Diagnostic screen will allow the user to test the motor by
pressing the TEST button. This will activate the motor briefly, to verify
operation and correct direction. The motor’s RPM will be displayed to
verify that the motor’s feedback sensors are working as well.
The Label Applicator Module Diagnostic screen tests the drive motor,
motor shaft encoder, and the gap sensor. With the system webbed and
calibrated, slide the label gap in and out of the gap sensor. View the
gap signal on the display. Press the Motor button and the label will
advance to the gap. At the end of the run, the approximate label length
will be displayed. If the length displayed is incorrect or doesn’t update,
there could be a problem with the motor shaft encoder.
