    In case of a fault however, a control of the flow rate is no longer possible and the gas flow fluctuates.

See the next pages of this chapter and chapter Gas flow controller adjustment and jumper settings...

  • Page 39: The Rectifier Could Also Be Faulty

    Fig. 18: Measurements - high voltage transformer Once there is voltage on the transformer the triac must be OK. A relatively low voltage on the transformer could be a result of too high current so that the HF-42 board reduces the phase angle. IF so there is most probably a faulty component in the oscillator circuit preventing it from oscillating so that the oscillator tube takes a high DC current.
