Sequences
7 Sequences
Sequences are fully automatic processes in which drives are moved and/or
the blade is heated when the cover is closed. A sequence is terminated if the
cover of the Biowelder
®
TC opens. Only sequences for which the user has
authorization and which the user can execute with the current machine
status are available on the user interface. For example, an Operator cannot
start a validation or the welding is possible only after an initialisation is
successfully run. The following chapter explains the special features of the
various sequences.
7.1 Initialise axes
All axes are initialised in this sequence. During initialisation all component
systems are tested to ensure greater process safety in the welding process.
The device decides when an initialisation is needed and prompts the user
to do it (e .g . after the machine is switched on) .
Closing the cover starts the initialisation, and it can be stopped at any time.
The initialisation sequence is aborted. Initialisation can be restarted at any time.
7.2 Weld
The welding process is described in Chapter 4.4 Function. Read Chapter 5.9
Welding to find out how a welding process is started.
A welding process can be aborted by the user through the Stop button . It
is impossible to stop the sequence during the critical section . During this
section the Stop button in the operator control disappears .
If the user aborts a welding process through the Stop button, the device
automatically reverts to the starting position . Read more about it in
Chapter 7 .3 Reverse .
7.2.1 Critical section
The critical section of a welding process is that range in which the automatic
sequence of the welding process should in no way be discontinued. The
critical section begins when the tubes are separated by the blade and ends
after they are welded.
The user cannot abort the critical section of the welding process through
the Stop button. An abort during this section is possible only when there is
network failure. Such a network failure must be avoided. Therefore, never
switch off the device.
We recommend the use of an uninterrupted power supply (UPS).
A network failure during the critical section of the welding process must
absolutely be avoided .
If the welding process was nonetheless discontinued during this section
because of a network failure or another problem, try to minimize the
damage by means of a subsequent rewelding or reverse. For more about
this, see Chapter 7.2.2 Abort in the critical section.
