6.3 Setting the Operating Mode of the Multifunction Relay
Procedure:
• Set the operating mode of the multifunction relay.
• If one of the following operating modes is used, you will need to carry out further settings for
the operating mode:
– Self-consumption/SelfCsmp
– Control via communication/ComCtl
– Battery bank/BatCha
Setting the Operating Mode of the Multifunction Relay
By default, the multifunction relay is set to activate a fault indicator if an error occurs. If you wish to
use the multifunction relay for another purpose, you will need to set the operating mode.
• Select the parameter Operating mode of multifunction relay/Mlt.OpMode and set the
desired operating mode (see Section 4.3 "Multifunction Relay", page 11).
Settings for Operating Mode Self-Consumption/SelfCsmp
• Set the power threshold from which a load is to be switched on. Select the parameter Minimum
On time for MFR self-consumption/Mlt.MinOnPwr and set the desired power.
• Set the minimum time for which the power must exceed the set threshold in order to switch on
the load. Select the parameter Minimum On power for MFR self-consumption/
Mlt.MinOnPwr and set the desired minimum time.
• Set the minimum duration for which the load remains switched on. Select the parameter
Minimum On time for MFR self-consumption/Mlt.MinOnTmm and set the minimum
duration.
Settings for Operating Mode Control via Communication/ComCtl
• Set the status of the multifunction relay where it is to be controlled via a communication product.
Select the parameter Status of MFR with control via communication/MltComCtl.Sw and
set the status.
Settings for Operating Mode Battery bank/BatCha
• Set the power threshold from which the battery is to be charged. Select the parameter
Minimum on-power of MFR battery bank/Mlt.BatCha.Pwr and set the desired power.
• Set the minimum time which must elapse after charging the battery before it can be charged
again. Select the parameter Minimum On power for MFR battery bank/
Mlt.BatCha.Tmm and set the minimum time.
