Current sensor
The current sensor supplied by Flybox® is able to measure current between -50 and +50 Amperes. It must not be installed
between battery and starter circuit because of the high current flowing into this path.
The current sensor can be installed in one of the three locations as shown in the simplified electrical diagram below:
Position 1: in this position the current sensor measure current flow into or out of your battery (indicator show both positive and
negative currents).
Position 2: in this position the current sensor measure only the current that the alternator supply to both battery and aicraft loads.
Position 3: in this position the current sensor measure the current flowing into the aircraft loads.
- Electrical connections:
NOTE:
•
To obtain maximum accuracy in the current indicator it's possible to perform current sensor calibration in this way:
1 -
Connect only the 3 wire from current sensor to the ECLIPSE and leave disconnected the 2 battery cable inputs (that is,
“A+” and “A-” in figure above).
2 -
Now it's required to turn-on th ECLIPSE so temporarily connect together the two cable “A+” and “A-”.
3 -
Turn-on th ECLIPSE and read the numeric value for the current indicator:
•
if it's zero there is no need to calibrate the current sensor.
•
if it's different from zero and is positive (in the green area) report that numeric value in the “AMP offset” parameter in
System setup-->Sensor menu.
•
if it's different from zero and is negative (in the yellow area) report that numeric value, but with negative sign, in the “AMP
offset” parameter in System setup-->Sensor menu.
4 -
Turn-off the ECLIPSE and restore the harness, reconnecting the two cables “A+” and “A-” to the current sensor.
