I had another occurence where a cleared integrator history in the tidal relieve servo to ETMX HPI  tripped everything at the end station.

To try to avoid that in the future I added p0.1:z10 filers on the HPI ISCINF input filters, and an p10:z0.1 anti filter BEFORE the switched integrator. This way any turn on or off should be soft.

We'll see whether it works.
