    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 controller's operating state as well as convenient configu- ration of the device via the primary control unit .
  • Page 9 Please also observe the following notes on start-up and operation: In case of operation in a 3-wire network, a zero-point creator is required (e .g . 700/100 V AC, primary 3-phase connection, available from KBR), as the controller needs a neutral conductor for trouble-free operation .
  • Page 10 Installation NOTE A phase-phase measurement (2 measuring phases without neutral conductor) is not possible with this device . NOTE For mixed operation of contactor stages and thyristor stages of the same size, the thyris- tor stages should be assigned to the stages in the back, as the front stages are switched first .

    . Controller preconfigured: If you wish to use a controller that is already integrated into a KBR compensation system by default, only the parameters of the current transformer need to be configured . 1. Configuring current transformer values All current transformer parameters need to be configured correctly for the compensation controller to function properly .

Function test A function test should be performed after all values have been programmed step by step, by disconnecting the controller from the power supply for a few seconds . The controller should start automatically after it is reconnected to the power supply . When reading out the CosPhi voltage in the cosPhi instantaneous menu immediately after switching on, CosPhi should be low and inductive .
