2.6 Functional test of the wiper for
Turbidity Plus with connector Fondriest
Cable
.
To perform a functional check on the wiper, connect the Pigtail colored wires to
the power supply and multi-meter following the steps below, shown in Figure 4.
4. Disconnect the yellow wire from the meter and connect the blue wire in its
place. It should read about 0 volts.
5. Briefly touch the green wire to the power supply ground.
6. The wiper should start rotating and the meter should read about 3.2 volts
until the wiper returns to its home position.
Figure 4.
Note: The sensor has built in protection if the wiper becomes blocked and
cannot move. In this case the wipe will stop and will try to return to the home
position the next time it is triggered.
Warning: Do not move the wiper by hand. This can cause permanent damage
to the sensor.
