  • Page 8: Operating Principle

    OPERATING PRINCIPLE The sunk-electrode humidifiers in the EASYSTEAM range use the conductivity of potable water to produce steam by boiling. The cylinder electrodes are sunk in the water: a current is generated between the electrodes and this heats the water to boiling point. Current intensity (expressed in amperes) varies according to the quantity of in-cylinder water that is in contact with the electrode surfaces and the conductivity of the water.

    Below description of specific connections for each functioning mode. In case it’s needed to connect 4-20mA probes not supplied by PEGO S.r.l. please call the technical dept. to verify hardware compatibility of the probe with humidifier. ON/OFF MODE: This kind of functioning allows steam production in only 2 modes: total lack of production or production at maximum.
  • Page 21 PROPORTIONAL mode with 0-10Vdc reference signal: This kind of functioning allows steam production proportionally to reference signal 0-10V. Example: a 6V reference signal will lead humidifier to produce 60% of steam referring to software variable Pr. So if Pr= 70% will be 42%. To set the second level variable S9=2 and make a bridge between terminal block 11 and 12, connect 0-10V reference signal to terminals 13 and 14, +V to terminal 13, GND to terminal 14.
  • Page 22 PROPORTIONAL mode with 4-20mA humidity ambient probe + limit duct probe (4-20mA): This functioning mode allows steam production in proportional mode, humidifier will regulate automatically the production of steam as per ambient request and the measured value into duct. To set the second level variable S9=3 and make a bridge between terminal block 10 and 11, connect 4-20mA humidity probe signal to terminals 8 and 9, signal RH to terminal 9, +V to terminal 8.

  • Page 40: Changing The Cylinder

    CHANGING THE CYLINDER The only part of the humidifier subject to wear is the electrode cylinder. This wears according to how much the machine is used or it is not possible to remove the internal incrustations. The EASYSTEAM range features stainless steel electrodes to maximise durability: however, durability will largely depend on the quality of the water (conductivity and hardness) and on how much the machine is used.
