CONTROLLER Em – EC-MANAGER:<\/p>\n

    \n
  • \n

    2 MODBUS RS485 connections (COM 0 on PC side & COM 1 on fan side);<\/p>\n<\/li>\n

  • \n

    Regulation mode MASTER (temperature or pressure probes) or SLAVE (0-20mA, 4-20mA, 0-5V, 0-10V);<\/p>\n<\/li>\n

  • \n

    Min. and Max. fan speed setting.<\/p>\n<\/li>\n<\/ul>\n

    Auxiliary contacts – available contacts:<\/p>\n

      \n
    • \n

      S1 – direct mode – reverse;<\/p>\n<\/li>\n

    • \n

      SP – selection of setpoints 1 or 2;<\/p>\n<\/li>\n

    • \n

      S5 – night speed limitation;<\/p>\n<\/li>\n

    • \n

      S2 – controller ON-OFF;<\/p>\n<\/li>\n

    • \n

      S6: max. spray speed enable.<\/p>\n<\/li>\n<\/ul>\n

      3 programmable relays: RL1 – general controller alarm; RL2 – fan alarm; RL3 – relay for heat exchanger cleaning start.2 programmable analog outputs (for fan regulation or spray activation).
      \nAdvanced functions:<\/p>\n

        \n
      • \n

        Emergency fan speed – fan rotation speed in the case of a control system fault (only on request);<\/p>\n<\/li>\n

      • \n

        Overspeed – possibility to increase the speed setpoint above the max. fan speed value (by-pass MAX RPM limit);<\/p>\n<\/li>\n

      • \n

        Speed-off – possibility to reduce the speed setpoint below the min. fan speed value (by-pass MIN RPM limit); Low capacity – is used to switch off groups of fans in the case of low temperatures, high temperature variations between day and night;<\/p>\n<\/li>\n

      • \n

        Anti-lock – is used to start the fans if they are supposed not to operate for a long time;<\/p>\n<\/li>\n

      • \n

        Washing – is used to program a washing cycle of the heat exchanger (start, frequency, duration), including reverse fan rotation and activation of the RL3 relay for washing system start-up;<\/p>\n<\/li>\n

      • \n

        Cleaning – is used to program a washing cycle of the heat exchanger (start, frequency, duration, rotation speed), including reverse fan rotation;<\/p>\n<\/li>\n

      • \n

        Possibility to operate the fans in reverse rotation.<\/p>\n<\/li>\n<\/ul>\n
