Technical manual

Different types of reset time can be selected as described in section

characteristics".

There is a possibility to activate a preset change (MultiPUx, x= 1, 2, 3 or 4) of the set

operation current via a binary input ENMULTx (enable multiplier). In some

applications the operation value needs to be changed, for example due to changed

network switching state.

The operation current value Ix>, is limited to be between Ix>Max and Ix>Min. The

default values of the limits are the same as the setting limits for Ix>, and the limits can

only be used for reducing the allowed range of Ix>. This feature is used when remote

setting of the operation current value is allowed, making it possible to ensure that the

operation value used is reasonable. If Ix> is set outside Ix>Max and Ix>Min, the

closest of the limits to Ix> is used by the function. If Ix>Max is smaller then Ix>Min,

the limits are swapped. The principle of the limitation is shown in Figure 55.
