4. Calibrate the sensor if necessary.
5. Run a cable to connect the sensor, making the connections in accordance with the selected connection
option (see section 5.3).
6. Check the operation of the sensor. To perform the check, connect the sensor and measure the voltage of
its output signal when dry
–
it should be wit hin the range of
0…3
V. Then measure the voltage of the output
signal when the sensor is completely immersed in fuel
–
it should
be within the range of
3.5…10
V.
7. Disconnect the sensor.
8. Install the sensor and fasten it using self-tapping screws (or regular screws, when mounting to native inlet).
9. Connect the sensor.
IMPORTANT NOTE: Be careful not to mix up the wires
–
connecting the wrong wire may result in damage
to the sensor.
IMPORTANT NOTE: DO NOT supply the sensor with a voltage in excess of 33 V!
5.5 End Cap
After having cut the sensor to length, insert the end cap (supplied with the sensor) into the cut end.
IMPORTANT NOTE: DO NOT use the sensor without the end cap
–
this may result in damage to the sensor
due to loosening of the tubes during use!
The end cap has three positions:
Position 1
Before inserting the cap in the cut end of the sensor, the
cap’s
core rod must be pushed up all the way into the
body of the cap as shown (Fig. 12).
Figure 12. End Cap in Position 1
Position 2
After insertion in the
sensor’s
end, the cap must be seated in place by pushing the rod in until it is flush with the
cap. This expands the cap
’s
wings and wedges it in the sensor centre tube (Fig. 13).
