Now we already check wiring conection for all thermocouple.
We found the problem,the interlock thermocouple to casting (isuzu machine) have problem,because when we disconect wiring thermocouple to interlock for casting machine,the thermocontrol shown looks normal.
Now we consentration to holding room,because now actual : holding room (528degree) and pressure room (784 degree).
I don't about this, can we supplay aluminium today with this condition? Because today the schedule first suplay aluminium.
I'm attaching a picture in preheat from you last time LP#1.
It shows temp in pressure room is higher than the one in holding room.
