EDM 930 in Bravo

[Fritz1]

Moritz and EDM 700 are working fine in my Bravo, fixed all the lights in Moritz, however before the Moritz bites me I want to replace it this coming winter, leaning towards the EDM 930 since very happy with the 700, my only concern are the alarms in the 930 which are factory preset and cannot be changed or disabled to my best understanding, so if a sensor puts out incorrect signal alarm will keep going off, therefore who has put 900 or 930 into Bravo, were there any alarm problems or any other problems?

The alarms are set by the factory in coordination with your POH and A&P so you should end up with the same redlines and limits as are specified in the original instruments. When a number has been exceeded, the EDM puts a line across the bottom of the display (for the 900, not sure about the 930) indicating the nature of the problem. One of the white buttons allows you to clear the error.

For cases where you exceed limits or have persistent a sensor error, this is a good design, and you can clear the error and get regular functionality back immediately with a single push.

It's an annoyance for intermittent errors. If an error is cleared and then later comes back, this display once again shows the problem and must be cleared with a button push again.

I had the EDM 700 for many years in my Bravo.  It served its purpose at the time. When I decided to upgrade the panel in 2013 I did a lot of research as to which engine monitor I wanted.  At the time the choice was between the EDM 930 and the MVP-50.  I read numerous comparisons (see PDF below for one).  In the end the multiple pages, character size, and added functionality of the MVP-50 won me over.  If I had to choose today, even with the addition of the Garmin EIS into the mix,  I wouldn't hesitate to make the same decision.

I've attached the same picture I have shown here in the past, but concentrate on the MVP-50 in the lower left hand corner.  The characters are just so much easier to read for me than on the 930, and the multiple ways the engine data can be presented (not shown) make it my engine monitor of choice.

If you do decide on it, definitely don't get the fast response probes.  They're unnecessary and go bad often.  The standard probes work well.

I’m curious how you fixed the lights in the Moritz. I recently lost two backlights on mine.

I put a 930 in a Bravo and had a 930 in a previous Ovation and had no problems whatsoever. They need the limits pages of your POH and they set it to the limits of your factory gauges. JPI was great to work with.

Thank you everybody, so the decision is between the 930 and the MVP50, will read up on the MVP50.

gdwinc, I have a series of pics how to change tiny bulbs in Moritz, PM me and I will send

Do they set them to alarm at the limit or over the limit?

I have an 830 and originally set the RPM to a redline of 2600.  But it alarmed AT 2600.  So I had to set the redline to 2610, so would not alarm at 2600, but would if it went over.

it alarms at the stated limitation - 2600 in your example. I don’t think any of primary monitors do it differently unfortunately.

They do allow setting additional user alarms, (they call it something else though) to alarm at a lower value such as setting a user alarm for CHT at 400F rather than just go by the limitation CHT redline that informs you that you need to replace your cylinder if it go over redline.
