Adjusting While Firing
Firing values can be adjusted while the ST315 is firing. Also there are
program pause/un-pause and segment advance features that are particulary
useful for glass work.
Adjusting Firing Values
While firing operate the
¨
key to select the required parameter as shown by
a flashing lamp on the mimic display. The firing value is shown on the main
display and can now be adjusted with the
©
&
ª
keys in the usual way. The
contents of the current segment or any segment still to be executed can be
changed. Firing will still carry on as normal while these changes are being
made. The ST315 will return to its normal running display 10 seconds after
key presses cease (or immediately after
End
is displayed).
Changes made to programs in this way are stored and are used for
subsequent firings.
Segment Advance Facility
While firing press and hold down the
©
key for about 4 seconds. The
ST315 will sound a short beep and the executing program will immedi-
ately advance one step as indicated by lamps on the mimic panel. The
effect of this is as follows:-
If a start delay is currently executing then the ST315 will terminate this
and start firing immediately.
If ramping is currently executing then the ST315 will switch to soak at the
current kiln temperature.
If currently soaking then the ST315 will advance to the next segment if
any, or else it will end the firing.
Changes made to the operation of the ST315 in this way are temporary
and are not stored.
