8.2 Dispenser Error Messages
In case of an error message the relevant output is switched. The signal can be used for
interconnection with an external machine control.
STO! Power-fail message
The message STO! appears in the display as the machine is switched off or if the mains supply
voltage has fallen below specification.
The message STO! (store) indicates that the machine has stored some parameters internally
as a power fail condition was detected. The error output is switched active and the ready output
inactive simultaneously with STO! appearing in the display.
If the mains supply voltage only experiences a drop in level and then returns to a correct level
then the ready output is restored to its previous condition but the message STO! will remain in
the display to indicate that there has been a problem with the mains supply.
Message Meaning How to solve
E__0 Pressure roller is open Close the pressure roll and make a new
initialisation if necessary
E__1 During material transport no label
is recognised over a length of 4
labels
Insert new material and check the label
sensor
E__2 EP applicator not in HOME
position
Check air supply.
Applicator not connected.
HOME switch not adjusted
E__3 Check sum of the configuration
data is wrong. All Parameters are
set
to the factory adjustment.
Call the configuration menu and adjust
all parameters again.
E__4 Check sum of the labelling data is
wrong. Labelling Parameters are
set to the factory adjustment.
All labelling parameter have to be
adjusted again
E__5 10V supply voltage for label
sensor low.
Short circuit in label sensor or cable.
Voltage regulator U14 is damaged.
E__6 24V Voltage low Short circuit on an output. Total load too
high i.e. max is 3A for all outputs.
Voltage regulator U1 is damaged.
Change main board.
E__7 Material initialization failed Check if the label web is threaded
through the label sensor
E__8 Error stepper motor driver The stepper motor control has detected
an error. The fault is indicated by the
LED’s on the driver.
E__9 10V supply for label sensor too
high
Voltage regulator U14 damaged
E__10 Missing label on product One or several product could not be
