6.25 Sequence Tools and Settings
The combination of Sequence and Time columns gives the exibility
to run a pre-set sequence of events that you may require for special
tool runs.
One possible use, shown here, would be to copy the same tool into
a few slots and then make separate adjustment for each occurrence
and run them in sequence. For instance it may be desirable to rst
heat up the manifolds only to a lower start temperature. Once that has
been allowed to settle you could then pick a second sequence which
would bring them up to normal temperature and then maybe a third
and fourth which would switch on all the zones at normal temperature
and put them into Run mode.
Initiating a Sequence start - locally
Once a sequence has been programmed then there is a “start” button
on this page which is labelled [
Sequence] which you can choose to
begin this temperature run-up pattern. However you can select “se-
quence” startup for a button one option on the display page. But note
it will only be functional while you have the appropriate tool loaded.
If you load a different tool and select [
Sequence] then an eror mes-
sage will show that no sequenced tool is selected.
Initiating a Sequence start - remotely
Alternatively, there is an option to use one input within the IO Card to
enable “Sequence” Start.
While the input is steady then the sequence will run at its preset timed
interals. However you can apply and release input to the IO Card and
this will force the tool sequence to move on to the next step. In effect
a 40-50 minute preset sequence can be pushed along by repeated
On/Off signals to the card and each pulse would step the sequence
past its internal timing to reduce the natural sequence to a few sec-
ond. This may be benecial for testing and initial settings.
