  • Page 8: Description Of Functions Of The Multicomp F144-3Ph

    Range of functions Description of functions of the multicomp F144-3PH The multicomp F144-3PH LCD reactive power controller works automatically in 4-quadrant operation (generator operation), i.e. even with energy recovery to the utility company network, missing compensation power is detected without a problem and compensated.
  • Page 9 By using an additional digital input, it is possible to activate a second deviating target CosPhi. Furthermore, the device is equipped with a RS485 bus interface for operation at the KBR eBus with the visual energy computer software. This enables comfortable visualization of the measuring values and the control- ler's operating state as well as convenient configuration of the device via the primary control unit.

    This display is used for the initial commissioning of the controller, where all the necessary settings can be made. Controller preconfigured: If a controller already integrated into a KBR compensation unit by default should be used, only the parameters of the current transformer have to be configured.
  • Page 21 Start-up guideline KBR multicomp F144-3PH 2. Function test After all values have been programmed, a function test should be performed. To do so, the controller has to be taken off the voltage supply for a few seconds. After re-connecting it to the voltage supply, the controller has to start auto- matically.
