Hard limiter ensures that power is reset to 0, if temperature of heating elements is too high (over
1080°C).
Soft limiter will ensure that heating elements are not rapidly switched on/off by hard limiter,
when near maximum allowed temperature. For this software will scale PID power: the close it
comes to 1080°C, the lower it become. At some point the power will become too low for the
heating to continue.
During operation software will continuously checking furnace and heaters temperature.
Whenever a dangerous condition is detected, a special window will appears on screen with
detailed message about what is wrong and acoustic signal will be given to the user. Power will
be turned off automatically during such event.
Messages
During operation following messages may appears (accompanied by acoustic signals):
Furnace thermocouple is disconnected!
Furnace temperature > 1200°C
Coil thermocouple is disconnected!
Coil temperature > 1200°C
Overheating!
Switch off the furnace immediately!
Coil temperature > 1080°C
Coil temperature is not increasing!
Heating, but coil temperature is not rising
fast enough
Coil temperature is not decreasing!
Cooling, but coil temperature is not
decreasing fast enough
Furnace temperature is not increasing!
Heating, but furnace temperature is not
increasing fast enough
Furnace temperature is not decreasing!
Cooling, but furnace temperature is not
decreasing fast enough
Coil temperature is lower than furnace
temperature!
Coil temperature < furnace temperature
When message appears, heater power will be reset to 0. This is indicated by red color of power
in Heater window. If analysis is in the progress, it may has to be terminated.
During analysis Phase, heater security logging will occur. The log file is normally overwritten at
the beginning of analysis. If security triggers a message, then this log file will be saved, allowing
investigate closely what happens with heater during analysis.

After introducing blank crucibles into a system it is necessary to specify ID for each of them.
This part can be speed up if auto-generated IDs are used.
There are 2 different features: blank crucible ID format and sequential numbering. It is even
possible to use them both simultaneously.
