8. Operation / Configuration / Adjustments
8.1 Putting in operation
Install the sensor in the piping (be sure the installation position is correct.
Refer to Section 6 Mechanical Connection).
Connect the sensor cable to the electronic analyzer.
(Refer to section 7 Electrical Connection).
Fill the piping with liquid.
Caution! There must be no air bubbles present at the sensor tip.
The flow speed must be 0.
8.2 Zero-point adjustment
Place the electronic analyzer in operation (switch on the supply voltage)
Rotate the flow potentiometer (1) (refer to section 11, “Brief operating
instructions”) counterclockwise as far as it will go (to the left-hand stop).
Rotate the temperature potentiometer (2) counterclockwise as far as it will go
(to the left-hand stop).
Briefly press the SET button for the zero-point adjustment (5)
(press it with a suitable object, such as a ball point pen)
The flow LED (6) will blink for approximately 30 seconds.
After this time has expired, the flow LED (6) will stop blinking.
If the system is not functioning properly, the flow LED (6) will blink
continuously. In this case, press the SET button (5) once again. The device
then switches back to measuring mode. Before continuing, inspect the
mechanical and electrical installation. Then follow the “Putting in operation”
instructions once again.
Switch on the system and set the maximum rated flow rate.
If the whole LED strip display is not illuminated, then the display can be
expanded so that the range from 0.25 to 1.8 m/s extends across the entire
LED strip display (see section 8.3 below).
8.3 Expanding the trend indicator
Rotate the flow potentiometer (1) (see illustration) clockwise as far as it will go
(to the right-hand stop). Then rotate the temperature potentiometer (2)
counterclockwise as far as it will go (to the left-hand stop).
Briefly press the SET button (5).
The flow LED (6) will blink for approximately 30 seconds. After this time has
expired, the flow LED (6) will stop blinking.
