2.8.2 DUT-E AF readings totalizing
DUT-E SUM AF summator designed by Technoton is used together with DUT-E AF sensors on
vehicles with two and more fuel tanks for measuring total amount of fuel (see figure 24).
ATTENTION:
1) DUT-E SUM AF summator operates only with DUT-E AF sensors with firmware
version 3.5 and higher.
2) Fuel tank calibration table should be recorded into the internal memory of each
sensor (see 3.10.7 ).
3) Readings can be totalized both analog (voltage) and frequency output signal types
of DUT-E AF.
Figure 24 — DUT-E SUM AF summator
DUT-E SUM AF output message contains total fuel volume (in liters) as a sum of the values
measured by sensors connected to its
IN and IN/OUT inputs.
Electrical connection of summators is carried out according to the diagrams provided in
figure 25 and in compliance with wire assignment provided in table 9.
Two DUT-E AF sensors are connected to the single tracking device according to figure 25 a.
If there are three or more fuel tanks to be measured with DUT-E AF sensors, cascade
connection can be used according to figure 25 b.
Quick splice connectors (ordered separately) are recommended for electrical connection of
signal wires.
