2.8 Monitoring of two and more tanks
2.8.1 DUT-E 232 readings totalizing
DUT-E SUM 232 summator designed by Technoton is used together with DUT-E 232 sensors on
vehicles with two and more fuel tanks for measuring total amount of fuel (see figure 22).
ATTENTION:
1) DUT-E SUM 232 summator operates only with DUT-E 232 sensors with firmware
version 3.0 and higher.
2) Fuel tank calibration table should be recorded into the internal memory of each
sensor (see 3.10.7).
Figure 22 — DUT-E SUM 232 summator
DUT-E SUM 232 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 23 and in compliance with wire assignment provided in table 8.
Two DUT-E 232 sensors are connected to the single tracking device according to figure 23 a.
If there are three or more fuel tanks to be measured with DUT-E 232 sensors, cascade
connection can be used according to figure 23 b.
Quick splice connectors (ordered separately) are recommended for electrical connection of
signal wires.
