  Информационные материалы

  The line-voltage sensing submodule is an optional module for line-voltage sensing and correction.

  The line-voltage sensing submodule is plugged from the front into the enclosure of the central interface module. The slot is located in the busbar area. If the line-voltage sensing submodule is not used, the opening is sealed by the busbar cover. If the line-voltage sensing submodule is used, the cover is used for shock-hazard protection.

  Дизайн

  • Connection of phases L1, L2, L3 and the neutral conductor via Teflon-coated cable
  • Board connector for central interface module

  Функции

  Line voltage compensation

  This function is required if the output power is to be corrected automatically in the case of strong line voltage fluctuations.

  To implement this function, a line-voltage sensing submodule must be plugged in to at least one central interface module in a network of several HCS724I heater controllers.

  The correction factors are calculated and transferred to the PROFIBUS DP master. The DP master then distributes these values to all HCS724I DP slaves.

  Voltage measurement for enhanced diagnostics

  To enable voltage values to be measured for enhanced diagnostics, a line-voltage sensing submodule is required for each central interface module.

  The determined voltage value is used for detecting faults in emitters connected in parallel.

  Note:

  The central interface module is only supplied from the factory without a line-voltage sensing submodule. If you want to compensate for line voltage fluctuations, you must order both modules (line-voltage sensing submodule and central interface module) and connect them together on site.
