Hi Folks--
I'm looking for some ideas as to why I'm seeing intermittent hi oil
pressure on my 912uls. Itis installed on a Zodiac 601XL and currently in
initial flight testing with about 5 hours on it. Everything was fine for
the first 3.5 hours. Current symptoms are that on start up and take off
everything is in the green at about 55-66psi. Once I reach altitude and
try to reduce throttle the oil pressure goes intermittently to the red at
78-98psi. If I throttle back up the pressure goes back to the green.
Returning to the field and after landing the pressure is again in the red.
Thanks for any ideas

George

hi George
what kind of oil filter are you using? and have you checked your oil
pressure with a different kind of gage(mechanical type) verses electric
sender type?. some times bypass in non rotax filter drags a little and
causes this.

Hi,

I'm not sure what type of gauge you are using but if you have the VDO type
that is supplied with the 91x series in Europe then note that when there is
power to the gauge but no connection to the sender the gauge shows full
scale (the temp gauges show zero in this case).
Check that you do not have a poor connection to the sender or a faulty
sender.

oil pressure unit and contact

Simon--
thanks for the suggestion. I've been in contact with Lockwood aviation
and that also was one of their suggestions.

Hi Guys,

This is an electronics or sender issue and not a filter issue. The bypass on the filter works on differential pressure before it opens and not normal system pressure. The bypass only opens if there is a difference in pressure between the upstream and down stream side of a filter.
