8.7 Setting the Tripping Threshold of the Residual-Current
Device
If a residual-current device with a tripping threshold of 30 mA is specified and installed, you must
set the parameter
RCD adjustment to 30 mA (for further information, see the Technical
Information ""Leading Leakage Currents"" at www.SMA-Solar.com).
The basic procedure for changing operating parameters is explained in another section (see
Section 8.5 "Changing Operating Parameters", page 49).
• Select the parameter RCD adjustment and set it to 30 mA .
8.8 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 8.5 "Changing Operating Parameters", page 49).
Procedure:
1. Select the parameter Operating mode of multifunction relay or Mlt.OpMode and set the
desired operating mode.
2. Once you have set the operating mode Self-consumption or SelfCsmp , you can configure
other settings:
• 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.
• 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.
• 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.
3. If you have set the operating mode Control via communication or ComCtl , select the
parameter Status of MFR with control via communication or Mlt.ComCtl.Sw and set the
desired value. This will configure the status at which the multifunction relay is controlled via a
communication product.
4. If you have set the operating mode Battery bank or BatCha , make further settings:
