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. Click on [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. In Self-consumption or SelfCsmp operating mode: 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 determines the power threshold at which a load is switched on.
  5. In Self-consumption or SelfCsmp operating mode: 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 determines the minimum time for which the power must exceed the minimum switch-on power threshold before the load is switched on.
  6. In Self-consumption or SelfCsmp operating mode: 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 determines the minimum time for which the load remains switched on.
  7. In Control via communication or ComCtl operating mode: 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.
  8. In Battery bank or BatCha operating mode: 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 determines the power threshold at which the battery is supposed to be charged.
  9. In Battery bank or BatCha operating mode: 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 sets the minimum time which must elapse after charging the battery before battery charging can resume.
  10. Select [Save all] to save the changes.
