Cause : Ext. supply VLT® Extended Relay Option MCB 113 is mounted without external 24 V DC. Either connect a 24 V DC external supply or specify that no external supply is used via parameter 14-80 Option Supplied by External 24VDC, [0] No.

  • A change in parameter 14-80 Option Supplied by External 24VDC requires a power cycle.
