If the selected event condition changes before the on delay or off delay timer expires, the relay output is unaffected.

4.6.5 5-5* Pulse Input

The pulse input parameters are used to define an appropriate window for the impulse reference area by configuring the scaling and
filter settings for the pulse inputs. Input terminals 29 or 33 act as frequency reference inputs. Set terminal 29 (parameter 5-13 Termi-
nal 29 Digital Input) or terminal 33 (parameter 5-15 Terminal 33 Digital Input) to [32] Pulse input. If terminal 29 is used as an input, set
parameter 5-01 Terminal 27 Mode to [0] Input.
