3.2 ON/OFF BUTTONS
The panel has combined on/off (stop/start) buttons for the machine. The green button
is to start the machine the red button to stop. When the start button is pressed the
machine will operate providing no alarm messages exist.
3.3 EMERGENCY STOP
The red Emergency Stop button located on the operator panel will stop the machine
immediately it is pressed. It is a safety feature of the machine and controls an
‘Emergency Control Relay’ to turn off power to all of the motors.
3.4 RESET BUTTON
Not used on this model.
3.5 MACHINE SPEED
There is only 1 motor fitted to the machine therefore label feed, applicator drum and
conveyor speeds are synchronized with each other. This dial controls the speed of the
machine. It has range of 0 to 10 and is lockable in any position to stop accidental
adjustment. Note that when set to zero, the machine will run at approximately 10% of
maximum speed.
3.6 FAULT MESSAGE INDICATION
A machine fault will first stop the machine then give a fault message indication on the
display at the operator panel in either RUN or SETUP mode. The fault must be
corrected before the machine can be restarted. The following list shows the standard
fault messages.
•
Emergency Stop
•
Label Runout (if fitted)
•
Overprint Fault (if fitted)
•
Missing Label Fault (if fitted)
•
Printer Fault (if fitted)
•
Guard Open
•
Barcode Fault (if fitted)
•
Motor Drive Fault
Note: When an Emergency Stop, Guard Open or Motor Drive fault occurs, the
machine will stop immediately whether or not it is in the middle of a labelling cycle.
When any of the other faults occur the machine will stop straight away, or if it is in
the middle of labelling a container it will stop at the end of that labelling cycle. The
situation can arise where a container is just about to be labelled and a fault condition
occurs, the container may then pass under the product sensor without being labelled.
Hence, depending upon specification of machine it is recommended that checks for
unlabelled containers are made after a fault condition.
