Faults
39
3.10.2 Other faults
– The screw for the upper furnace cushioning is too tight, see chapter “Pneumatics”
– The pressure switch does not close. Measure the voltage across its leads. Zero volts with
pressure, 24 VDC without pressure.
– The furnace closes too slowly, adjust according to chapter “Pneumatics”
– The furnace does not close: see chapter “The induction furnace does not close”
3.10.3 Resistance furnace operation
– Check the oxygen pressure on the upper pressure gauge. The pressure should be about
1,5 bar (22 psi). If lower, see Chapter “No or low oxygen pressure”
– Check the pump voltage in the “Device state window”.

If in the device state the graphs of IR-temperature °C or %IR are not in the green area, adjust
the temperature. See chapter “IR-cell temperature control”.

: Device state
– Thermostatic control reports 0% or 100% power:
The percentage of power required by the thermostatic control is displayed in the Device State
Window . The power is 100% after switching on from cold while heating up. It takes about
30 minutes for the temperature to reach the set point. In stable condition, the power required
should be between 30 and 70%.
If the value is less than 30%, adjust a higher temperature set point. If the value is over 70%
without any tendency for coming down to lower values, adjust a lower set point.
