Errors And Warnings; Dispenser Error Messages - Avery Dennison ALS 321 User Manual

Operators Manual
ALS 321/421

5. Errors and warnings

The software continuously checks during the labelling, whether normal operation is possible. If
labelling is not possible, the display shows a message e.g. E_XX. If labelling can be continued,
although a problem has been recognised, the display shows a warning e.g. W_XX. By pressing
the key FEED the message will be erased.
Error and warning signals are available at the outputs and may be used for external purposes.
If an error cannot be erased, please call your local AVERY service technician.

1.1 Dispenser error messages

In case of an error message the relevant output is switched. The signal can be used for inter-
connection with an external machine control.
Message Meaning
E__0 Pressure roller is open
E__1 During material transport no label
is recognised over a length of 4
labels
E__4 Check sum of the labelling data is
wrong. Labelling Parameters are
set to the factory adjustment.
E__5 10V supply voltage for label sen-
sor low.
E__6 24V Voltage low
E__7 Missing label on product
E__8 Error stepper motor driver
E__9 10V supply for label sensor too
high
E__10 24V supply too high
___0 Process error (Divide overflow)
Release 2/08
How to solve
Close the pressure roll and make a new
initialisation if necessary
Insert new material and check the label
sensor
All labelling parameter have to be ad-
justed again
Short circuit in label sensor or cable.
Voltage regulator U14 is damaged.
Short circuit on an output. Total load too
high i.e. max is 3A for all outputs.
Voltage regulator U1 is damaged. Chan-
ge main board.
One or several product could not be la-
belled. Distance between products too
close. Increase speed of printer.
The stepper motor control has detected
an error. The fault is indicated by the
LED's on the driver.
Voltage regulator U14 damaged
Voltage regulator U1 damaged
Hardware failure external noise. EPROM
damaged. Turn off power and on again.
Change EPROM or main board
