3.11. Temperature Control
To use the temperature controller a thermocouple
type N article no 13400010 up to 1300°C (parameter -01- must be set to 0002) *
or
type S article no 13000030 up to 1600°C (parameter -01- must be set to 0001) *
Has to be connected to the socket inside the casting chamber. Very important is that
you use the thermocouple together with the thermocouple protection cover article no
13200045.
Important: Use thermocouple for
melting only in crucibles with graphite
inlet. Otherwise induction energy will
stimulate thermocouple directly (without
protection by graphite). Result, read in
display, is pure nonsense!
The nominal temperature can be set with the buttons "+" and "-". The heating power
is now controlled by the temperature controller.
If the temperature control is not in use (e.g. for temperatures above 1600°C, platinum
alloys) the dummy plug must be connected to the thermocouple socket. The machine
automatically switches to the manual heating power mode. The heating power can
now be adjusted with the buttons "+" and "-" (display "P00" to "P100").
Without thermocouple, without dummy plug or with defective thermocouple the
display shows "E041".
Attention: Do not use a thermocouple in direct heating
process! Energy will melt thermocouple! If you use graphite
crucible and thermocouple the output power needs to be
reduced to 50%. Otherwise the temperature overshoot is too
high and will burn the thermocouple.
3.12. Tree making
Pieces made of wax/plastic must be placed in „tree“ form.
This is done by a small soldering needle + wax wire.
On bigger trees for bigger machines there is a main wax sprue (ø 8-10 mm).
