  • Page 4: Application

    If, for technical or other reasons, this solution is impossible and there exists a suitable communication channel (cable or other media) between the points, the NRC86 remote controller can be used for driving the capacitor contactors.

    Default values are –0.95 / -0.97 / 1.00 / 0.97 / 0.95 , but they can be freely changed. According this setting the PFC keeps preset target PF value that is dynamically controlled by the remote controlled PF serial number from the NRC86 unit ( standard target PF value in parameter 01 has no meaning in this mode).

    ( i.e. a medium with no transmission delay) is used (it depends on preset communication rate and remote control mode). If usual metallic cable is used maximum distance between the PFC and the NRC86 unit is up to 1 km, but it can be nearly unlimited for suitable wireless media.

  • Page 9: Parameters 30 - Alarm Setting, 40 - Alarm Status

    If the metering rate 2 control is enabled and any of the RCC-modes is set simultaneously, the target PF is remote controlled by external NRC86 unit only when the metering rate 2 (tariff 2) just active. In such case, the actual value of remote controlled PF with preceding „E“ character is displayed in parameter 07 ( in the same way as in the parameter 01 when the metering rate 2 control disabled).

  • Page 10: Alarm No. 15 - Remote Control Failure

    When temporary interruption of the connection between the PFC and the NRC86 unit/units appears, the situation will look as follows : 1. Approximately after 20 seconds of communication link fault the PFC disconnects all of outputs step by step and it will stay in standby mode until the connection is restored.

  • Page 11: Parameters 50, 51, 52 - Instrument Address, Communication Rate And Communication Protocol / Nrc86 Response Timeout

    GSM/GPRS modems, LAN etc., it is necessary to set this parameter value to maximum wait time for response from the NRC86 i seconds ( in range 1 – 2 – 3 – 5 – 8 ). If the remote control mode is switched off the parameter 52 has its usual meaning – the type of communication protocol.
  • Page 12 NRC86 unit, all of others must be set as „slaves“, that means to passive RCC-mode marked as RCCP. As soon as the mode is set, the master PFC starts to send commands to the NRC86 unit(s). The unit (with address of 200 if more units connected) receives them, processes them and sends confirmation back to the master PFC.

  • Page 13: Parameters 80,81 - Remote Controlled Target Pfs And Remote Controlled Pf Serial Number

    In the RCC-mode , co called serial number of remote controlled PF is periodically transferred from the (first) NRC86 unit to the PFC (or multiple PFCs). Its range is 1 ÷ 5 and actual value is displayed in parameter 81with identification string „ECn“; for example, if its value is 2, the...

    3. NRC 86 Remote Controller The unit is designed for power factor compensation systems either with remote controlled PF or with remote controlled outputs. The unit operates in combination with special version of Novar power factor controller – Novar1xxx NRC.

  • Page 15: Operation

    3.2.1 Remote Controlled Power Factor (Cosinus) Mode – the „RCC“ Mode Up to five pulse signals can be connected to the NRC86 unit. A pulse of correct duration on one of inputs 1÷5 is evaluated as target PF serial number request. The unit saves the number into its memory and confirms by switching of appropriate output on ( this signal is transmitted back to the supervising system for checking ).

    KMB systems 3.4.3 Logic Inputs The NRC86 unit can have up to 8 galvanically isolated logic inputs (depending on unit model). The inputs are passive – a voltage of appropriate level ( specified in technical parameters, see below ) must be applied. For direct voltage inputs the applied voltage polarity is free. The input voltages must be connected to terminals 29 ÷...

  • Page 20: Putting In Operation

    For remote controlled power factor the NRC86-85 24 VDC remote controller is needed. If remote controlled outputs using additional NRC86 units in cascade necessary too it is better to use the NRC86-07 230 VAC models with 7 outputs each for this task.

Up to 7 of such NRC86 units depending of number of compensation system outputs (contactors) and required spatial spread can be used.

The NRC86 unit(s) must start to indicate the communication link failure alarm during approx. 15 seconds and after 30 seconds to disconnect all of outputs at once.
