    PCOUMID000 CARD / PCOUMID200 This interface allows controlling the basic quantities of the OEM humidifiers produced by CAREL, that is level, feedwater conductibility and current absorption. The pCO1 – pCO2 board directly controls all values. The interface transforms the humidifier signals into signals readable by the cards.

  • Page 13: Built-In Humidifier

    BUILT-IN HUMIDIFIER Integrated management of a Carel immersed electrode humidifier. The pCO1 - pCO2 boards manage all the functions, from the reading of the humidifier parameters to the control of the devices (fill, drain, output) by relay. The humidifier parameters (current, conductivity, level) are not read directly, but rather using an optional card (PCOUMID000 / 200).The built-in humidifier is available for pCO1 - pCO2 medium boards only and replaces...

    The algorithm also controls the drain cycles, signalling a drain alarm if there is no appreciable decrease in current when the drain cycle starts. Vice-versa, a no water alarm will be signalled if there is no appreciable increase in current when the humidifier is being filled with water. Carel Cod. +030221421 – Rel. 1.2 – April, 11, 2003...
