5.2.5 Re-starting the machine
There are four situations whereby the machine has (been) stopped and a re-start is possible.
The stages to be gone through to re-start the machine depend on the way the production
process was interrupted. To re-start the machine appropriately, follow the staged plan
applicable to the type of interruption that has taken place.
5.2.5.1
'Machine stop’ button pressed
Once the ‘stop’ button on the control panel has been pressed, the machine stops, the forming
die remains closed and its parts remain active. The program settings also remain active (stop
“LED” will flash). The process can be resumed by pressing the ‘start’ button. To stop the
program, press ‘stop’ button twice. (stop “LED” stays on)
5.2.5.2 Failure in the safety circuit
All failures are displayed on the touch screen: the type and location of the failure is indicated.
Since safety is in jeopardy, the cause of the failure needs first to be traced and corrected
before production is continued. Chapter 7.2 gives information for correcting failures. When the
failure has been corrected, press the ‘reset’ or ‘stop’ button.
To bring the machine back to ready mode, activate the ‘stop’ button twice with an interval of 2
sec. or more. The process can be re-
started by pressing the ‘start’ button.
5.2.5.3 Emergency stop when a format part is closed
An ‘emergency stop” when a format part is closed implies that during the forming of the
underside or the sealing of the packaging an ‘emergency stop’ has been made. The heating
and vacuum pump(s) will be shut down and the format parts stay at their current position.
Since safety is in jeopardy, the cause of the failure needs first to be traced and corrected
before production is continued. Then take the following steps:
-
Release the “emergency switch” by turning the red button to the left. The “emergency
switch” will than be in it’s ‘on’ position.
-
Press the ‘reset’ button or press ‘stop’ once.
-
Turn on the heating.
-
Turn on the internal vacuum pump
-
Press
‘stop’ button twice with interval of 2 sec. or more, to initialise the die positions.
-
The process can be resumed with the ‘start’ button.
5.2.5.4 Emergency stop during film transport
Finally there is the situation that occurs when the emergency switch is activated during film
transport or halfway through a cutting process. In this situation all parts stop moving and the
products to be packaged are not yet fully inside the machine. In this case take the following
steps:
-
Inform the technical department advising them of the cause of the problem to be solved.
-
Release the “emergency switch” by turning the red button to the left. The “emergency
switch” will than be in it’s ‘on’ position.
-
Press the re-
set button or press ‘stop’ once.
-
Turn on the heating.
-
Turn on the internal vacuum pump.
-
Press the transport button to initialise the transport movement. When transport is not
initialised the background of the button will flashing in red.
-
Machine is ready to run, restart the process with the ‘start machine’ button.
