... Replacing the frontend board
In the event of a fault, the frontend board can be replaced on
flowmeters with an integral mount design.
Replace the frontend board as follows:
1. Switch off the power supply.
2. Unscrew / remove the cover.
3. Remove the LCD indicator. Ensure that the cable harness
is not damaged.
4. Pull the connector out of the sensor cable harness.
5. Pull out the SensorMemory.
Note
The SensorMemory is assigned to the sensor. The SensorMemory
is therefore fastened to the sensor cable harness with a cable
retainer.
Ensure that the SensorMemory remains with the sensor and
cannot be lost!
6. Pull the faulty frontend board out forwards.
7. Insert new frontend board.
8. Attach connector from the sensor cable harness.
9. Attach the SensorMemory.
10. Insert the LCD indicator and screw on / replace the cover.
11. Once the power supply is switched on, load the system
data from the SensorMemory.
