KNF Rotary Evaporator - Inspiringly Easy To Use
Controller Model TIC/3 heads.
This controller is connected to rotary pump E2M1.5 and turbomolecular pump. Recently, we shut down system to service the rotary pump. Upon re-starting, the Controller TIC shows gauge "Not Connected" and "Warning TICtmp". The display appears dim. The gauge is definitely connected. Under "Service Information" , the PSU and TIC temp both shows -273.0C. Any advice?
