10 Temperature Control
10.1 Main Chamber & After Burner
10.1.11 Screen-view Temperature Control Screen
Temperature control of the Main Chamber and After Burner is made using two independent PID
control algorithms. The status of the control can be viewed on the Temperature Control screen
(Screen-view 10.1.11 ) which is accessed via:
Home Screen → Main Menu → Temperature
The temperature readings on the left of the screen show the current temperature of the
chambers. If a thermocouple connection is broken then the LED colour is red, as shown for the
after burner in Screen-view 10.1.11. If the connection is good, the LED is coloured green. The
Main Chamber set point can be changed by pressing the white box, which will cause a number
pad to pop-up. The After Burner set point is factory configured to be 900°C. If a recipe is
selected, (ref. Section 7.2) then the Main Chamber temperature set in the recipe will show on
this screen. The temperature set point can be changed during a test.
The After Burner operating temperature is factory set and should not need to be changed.
The heater power percentages, on the right hand side of the screen, indicate the amount of
power being applied to the electric heating elements. This is controlled by the PID algorithm.
