For our US friends: If you haven't already discovered it, look at
windmapper.com It gives instant decodes of all airfield Metars, together
with all sorts of extra brilliant features. I understand it has only
recently started up, but its equivalent European service xc weather has been
a firm favourite here for some time. Regards, David Joyce, G-XSDJ

Hi David
Thanks for that, I can use it whilst over here in the U.S. but tell me about
"XC Weather" I've never come across it?

Hi Martin,
Since pressing ACK for oil pressure makes the light stop flashing, that is what
is generating the alarm. The light is staying on because the oil pressure is
still out of limits. This is explained on Figure 1b of the EIS manual. Check
that your oil pressure is between the lower and upper limits you have set.
If fuel pressure (Aux input) were causing an alarm, you would have to press Ack
to extinguish that alarm. And setting limits to 0 causes EIS to ignore that
input from an alarm point of view (see page 7 of EIS Manual).
My bet is that you either have low oil pressure limit set higher than what your
oil pressure is indicating or high oil pressure is set lower than what your oil
pressure is indicating. Is your oil pressure indicating what you expect?
Are you using GRT or Rotax oil pressure sending unit? Not sure what a Mitchell
sending unit is but EIS probably isn't calibrated for Mitchell's.
For fuel pressure, the easiest solution is to purchase the sensor from GRT. It
will come with the SF and Offset information. You could calibrate the existing
Mitchell sensor if you have or can obtain the resistance vs pressure data.

Hi Jim,
Thanks for the thoughts. The initial trigger for the warning light is low oil pressure
but once the engine starts the oil pressure is where it should be and
within the upper and lower limits that are set - in fact the unit came with the
upper and lower units already set for a Rotax but I double checked anyway.
In fact once the engine is started and warmed up all the parameters are within
limits (except that pesky CHT2 which stays at around 60-80 deg F - but there is
no 'Low CHT Temp' parameter so should not be causing a warning) but the warning
light stays on and I can't figure out why.

I've had this system for some time and like it very much. If you have an out
of limits issue the warning light blinks and continues until it is no longer
out of limits and then the light goes out or if you "acknowledge" the issue
the light burns steady ( I suppose so it is not quite as annoying) until it
is fixed. If the oil pressure is the offending limit I would go back into
the settings and reset your upper and lower limits yourself. In any case
what ever is coming up on your EIS as the problem I would go to that and
readjust and reset the EIS. Hopefully that will work if not I would call and
speak to their tech. people who have always been helpful. Good luck.

Martin,
Perhaps you have a CHT span warning as I did with my stratomaster
monitor. I have made inserts to the front round openings that shoot the
air up over the cylinders and now have fairly even cooling within 15
degrees. Still a bit high but I'm working on that. I'm considering a
ram inlet on the top of the cowl of some sorts.

Martin,
When you power up EIS, the red light comes on flashing, correct?
And when it does, the page showing has Oil Press on it and that value is blinking,
correct?
And when you push ACK, the light quits blinking but stays on steady and the default
display page (usually fuel qty & flow display page 0) comes up, correct?
Then you start up and the light stays on, not blinking, correct?
If all these are true, the problem is in the oil press low/high limits or the pressure
measurement. Be aware there are two low oil press settings - one is Min
OilP and the other is Min Crz_OP. Have a look at page 9 of the EIS manual.
Min OilP is set at 22 and Max OilP is set at 98 for my 914. Note that Max OilP
must be set less than 99 - if it's set over 100 that may be your problem.
