T18 as Pulse Input (Menu Index 9.4.4)
7.9.2.4
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 18 act as frequency reference inputs. Set terminal 18 (P 9.4.1.6 T18 Digital Input) to [32]
Pulse input.
