Changing the Operating Mode of the Multifunction Relay


Qualified person

The default operating mode of the multifunction relay is Fault indication (FltInd) . If you decide to use another operating mode and have established the correct electrical connection for this operating mode and the associated connection variant, you will have to change the operating mode of the multifunction relay and make other settings, if necessary.

The basic procedure for changing operating parameters is explained in another section Changing Operating Parameters).

Procedure:

  1. Call up the menu Device Parameters.
  2. Select [Edit parameters].
  3. In the parameter group Device > Multifunction relay > Operating mode select the parameter Operating mode of multifunction relay or Mlt.OpMode and set the desired operating mode.
  4. Once you have set the operating mode Self-consumption or SelfCsmp, you can configure other settings:
    • In the parameter group Device > Multifunction relay > Self-consumption > Minimum On power select the parameter Minimum On power for MFR self-consumption or Mlt.MinOnPwr and set the desired value. This will configure the power threshold from which a load is to be activated.

    • In the parameter group Device > Multifunction relay > Self-consumption > Minimum power On time select the parameter Minimum power On time, MFR self-consumption or Mlt.MinOnPwrTmm and set the desired value. This will configure the minimum time for which the power must have exceeded the minimum switch-on power threshold in order to trip activation of the load.

    • In the parameter group Device > Multifunction relay > Self-consumption > Minimum On power select the parameter Minimum On time for MFR self-consumption or Mlt.MinOnTmm and set the desired value. This will configure the minimum time for which the load remains activated.

  5. If you have set the operating mode Control via communication or ComCtl, in the parameter group Device > Multifunction relay > Control via communication > Status select the parameter Status of MFR with control via communication or Mlt.ComCtl.Sw and set the desired value. This determines whether the multifunction relay can be controlled via a communication product.
  6. If you have set the operating mode Battery bank or BatCha, make further settings:
    • In the parameter group Device > Multifunction relay > Battery bank > Minimum On power select the parameter Minimum On power for MFR battery bank or Mlt.BatCha.Pwr and set the desired value. This will configure the power threshold from which the battery is to be charged.

    • In the parameter group Device > Multifunction relay > Battery bank > Minimum time before reconnection select the parameter Minimum time before reconnection of MFR battery bank or Mlt.BatCha.Tmm and set the desired value. This will configure the minimum time which must elapse after charging the battery before the battery can be charged again.

  7. Select [Save all] to save the changes.
