3. On the right-hand side of the menu bar, select the menu User Settings (see Section4.3 "Start
Page Design of the User Interface", page27).
4. In the context menu, select [Starting the installation assistant].
5. Select [Save and next] until you reach the Safety functions step.
6. Configure the Rapid Shutdown function according to the DC disconnection unit used.
4.15 Changing the Operating Mode of the Multifunction
Relay
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 (see
Section4.11 "Changing Operating Parameters", page34).
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.
