SV-EMS-220/221 Installation and Configuration
7-78 SkyView System Installation Guide - Revision AA
For example, you could set up two ranges for the same gauge, each 0-10, one Red, and one
Green, and that range would be Red. To further illustrate this behavior, if another range for
that same gauge was configured from 5-15 and set to Yellow, only 10-15 would be Yellow.
The two edge ranges are considered to go on "forever," so if a gauge is set up as Yellow from 10
to 20 and Red from 20 to 30, and the sensor reads 35, it will still be considered Red since that is
above the highest range. It will be considered Yellow below 10. If you wish for this not to occur,
you must make your edge ranges Black.
Alarms are only triggered when ALARM: SELF-CLEAR or LATCHING and the value enters a Red
range on a gauge. When values enter into a Yellow range, their numerical value is highlighted in
Yellow to annunciate the caution condition.
Fuel Computer Configuration
Setting Pulses/Gallon
To find and configure the pulses/gallon value associated with your fuel flow transducer:
If you have the Floscan 201B (Dynon Avionics P/N 100403-001), this number can be found on
the tag that came with the transducer. The pulses/gallon value for transducer is 10 times the
number shown after the dash. So, if your transducer had the tag that is labeled “16-2959”, you
would enter a pulses/gallon value of 29590 in the pulses/gallon section of SETUP MENU >
HARDWARE CALIBRATION > EMS CALIBRATION > FUEL FLOW CALIBRATION. If you have lost
your tag, a starting pulses/gallon of 30000 will be close enough to begin using the function.
If you have the EI FT-60 “Red Cube” (Dynon Avionics P/N 100403-003), enter a starting K-
VALUE of 68000 under SETUP MENU > HARDWARE CALIBRATION > EMS CALIBRATION > FUEL
FLOW CALIBRATION.
Over time, you may notice that the instrument’s computation of gallons or liters remaining
(based on fuel flow) is either high or low. This is a result of many factors, including individual
installation. To correct for this, follow this procedure:
Over several fill-ups keep a running total of the amount of fuel added. Keep a running total of
the GALS (or LTRS) USED parameter over this same time span.
Perform the following calculation:
. You should obtain a number that is
close to 1. We’ll call this number, FuelFlowRatio.
Now perform this calculation: CurrentPulsesPerGallon*FuelFlowRatio. Enter this number as
your new pulses/gallon value.
Observe the results over your next tank for accuracy. Repeat the above if necessary.
The general rule of thumb: if your GALS (or LTRS) USED reads higher than you expect, increase
the pulses/gallon; if it reads lower than you expect, decrease the pulses/gallon.
If your engine has a return fuel flow sensor, note that there is a second pulses/gallon setting
that is mapped to a second set of input pins. When a second fuel flow sensor is connected and
