Adjusting While Firing - BONIS ST535 User Handbook Manual

Adjusting While Firing

Firing values can be adjusted while the ST535 is firing. Also there are pro-
gram pause and program advance features that are particularly 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 ▲ & ▼ 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 ST535 will return to its normal running display 20 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.
Program Advance Facility
While firing press and hold down the fn key then press the ▲ key to obtain the 8
(advance) function. The ST535 will sound a short beep and the executing pro-
gram will immediately advance one step as indicated by lamps on the mimic pan-
el. The effect of this is as follows:-
If ramping then the ST535 will switch to soak at the current kiln temperature.
If soaking then the ST535 will advance to the next segment if any, or else it will
end the firing.
Changes made to the operation of the ST535 in this way are temporary and are
not stored.
Program Pause Facility
While firing press and hold down the fn key then press the ▼ key to obtain the ‫װ‬
(pause) function. The ST535 will sound a short beep and the executing program will
pause at the current kiln temperature. The pause indicator (‫ )װ‬will light. To release
the pause repeat the above action.
PAUSED
WARNING - PROGRAM PAUSE
The program pause facility should be used with care. Program execution is suspended
and the kiln will be held at its current temperature. If left too long at high temperatures
kiln damage could result. Pause will automatically release after an Installer-defined time
period (default: 2 hours - see Installation Handbook).
