C.
Connection type.
The Adapter support multiple sensor’s types (resistive, voltage, Volvo Penta MDI)
and different connection schemes (standalone, in parallel with 1-coil or 2-coil gauges). In case of a
parallel connection, you should measure the resistance of a gauge’s coils and specify it in the Device’s
settings; this is possible with the second configuration method only.
With the factory settings, Device channels are configured for using with USA resistive sensors (240
Ohms when empty, 33 Ohms when full). Tank numbers for channels A, B, C, and D, are 0, 1, 2, and 3
correspondingly. Fluid type is set to diesel for all channels. These settings are correspond to configuration
preset #1.
Aside from the connection type and fluid type, the following settings (can be configured with the second
method only) can improve the accuracy of readings:
D.
Calibration.
Resistive fuel level sensors do not take the shape of the fuel tank into account, therefore,
the readings usually have substantial error. The same issue is applicable to the voltage-output sensors
which do not have an internal calibration mechanism or do have a non-linear output. The Adapter
allows setting a 12-point calibration curve for each channel.
E.
Capacity.
If the capacity for a tank is specified, your MFD will allow display of a tank’s level not only
in percent, but in liters or gallons also. In factory settings, capacity for all tanks is set to UNKNOWN.
F.
Damping.
With factory settings, the Adapter transmits the average value measured in last 3 seconds.
This can be too small for rough sea conditions and too big for some applications (e.g., controlling of
live well pump or fuel pump with digital switching).
We recommend learning about both configuration methods before configuring the Device.
