Applications with 3-Pole Tripping
For applications with only 3-pole tripping options, the internal operate indications are always 3-pole. For
external starts, there is a binary input, which signalizes a 3-pole tripping of the external protection device.
The outputs of the input logic signalize that the reclosing start has occurred through a 3-pole operate indica-
tion.

Figure 7-32 Input Logic for Operating Modes: With Tripping
Input Logic for Operating Modes with Pickup
The operate indications and the pickup indications are used as starting signals. The internal pickup indications
are processed selective to the phase. Through binary inputs, the pickup information can also be coupled by
external protection devices (
>Pickup A for start
,
>Pickup B for start
and
>Pickup C for
start
). Optionally, the pickup information can be externally captured as a pickup sample, thus, as a 1-phase,
2-phase and 3-phase pickup.
The outputs of the input logic signalize if the automatic reclosing start occurs through a 1-phase, 2-phase, or
3-phase pickup:
•
On Start with 3-phase pickup, it is recognized if all 3 phases were picked up in the period from the first
raising pickup indication up to the last clearing outgoing pickup indication.
•
On Start with 2-phase pickup, it is recognized if all 2 phases were picked up in the period from the first
raising pickup indication up to the last clearing pickup indication and at no time 3 phases.
•
On Start with 1-phase pickup, it is recognized if only 1 phase was picked up in the period from the first
raising pickup indication up to the last clearing pickup indication.
