Problem with IGNORED sensors in EQM-classes

In a'n class based EQM, we have some instances, that have IGNORED sensors. This causes a Input Transfer Failures and brings the MERROR to NonZero. Why a IGNORED Block brings in this bad status?

The MERROR has a Input Transfer Failures because E2 Block is ignored

The OUT_D of the IGONRED Block gives the status of GoodNonCascade

On the wired IN_D1 (of the XFR2-Block) comes the state of Bad NoCommNUV. Must i have a DUMMY DI to bind it on the block E2 with the Interface parameters of the DI-Class? Or how can i solve the problem with the Inpu Transfer Failure?
