An external signal, which is connected to the input DLD-BLOCK, blocks the function.
The function is also blocked by the setting Block-DLD=Yes if the terminal is in test
mode.

The parameters for the dead line detection function are set via the local HMI or PST
(Parameter Setting Tool). Refer to the Technical reference manual for setting parame-
ters and path in local HMI.
Due to technical reasons settings are shown under Setting/Group n/DeadLineDet de-
spite that they have no influence on the function. On the local HMI the parameters for
the dead line detection function are set under the two menus for TUV and Z(n)RW.
Set the operate voltage UPE< at least 15% lower than the lowest phase-to-neutral volt-
age with normal operations.
Set the operate current IMinop at least 15% lower than the lowest phase-to-neutral cur-
rent with normal operations.
The settings must be coordinated with TUV and Z(n)RW since UPE< and IMinop are
common.
