Initiation of Measurement
Normally the fault location calculation is started when a directional or non-directional time overcurrent protec-
tion initiates a trip signal (address 8001 START = TRIP). However, it may also be initiated when pickup drops
out (address 8001 START = Pickup), e.g. when another protection element clears the fault. Irrespective of
this fact, calculation of the fault location can be triggered externally via a binary input. (FNo. 1106
>Start
Flt. Loc
) provided the device has picked up.
