5.1.1.4.6 Manual calibration
If a custom designed characteristic curve has already been established and the curve shall be
duplicated on an other FC01-Ex, it is possible to enter the data for the various points by hand.
The method is largely identical with that for automatic calibration.
The heating power belonging to the flow velocity is not determined automatically but rather
entered on the FC01-Ex by hand.
It is also possible to make the calibration combining automatically determined and theoretically
calculated trim points.
5.1.1.4.7 Calibration temperature
After confirmation of the last trim point, TRIM IS READY! is displayed.
The second line on the display will show the medium temperature in °C at which the calibration
was made. With automatic calibration, the calibration temperature is displayed non-flashing and
cannot be changed by hand.
If the calibration data were entered by hand, the calibration temperature must also be set by
hand. In that case the temperature value will be flashing.
Note:
❑ The medium temperature must be kept constant over the entire calibration process!
5.1.1.4.8 Storing the characteristic curve
Before quitting the CUSTOMER TRIM menu, the FC01-Ex shall be informed whether the custom
designed curve determined or entered shall be stored in a permanent (touch switch ✭) or volatile
way (▲ UP or ▼ DOWN).
If the characteristic curve shall be stored in a volatile way, it will be deleted upon failure or power
disconnection.
Note:
❑ If a power failure occurs during the calibration, the entire calibration must be repeated!
5.1.1.4.9 Potential errors during the calibration
All errors found during the calibration are indicated with their relevant number.
If one of the following errors occurs, it is not necessary to repeat the entire calibration but rather
the calibration of the trim point where the error occurred.
Error Cause Rectification
No. 10 Sensor not connected, or cable between Check cable or replace the
FC01-Ex → and sensor defective; pair electronic control unit +
or defective sensor monitoring head.
No. 21 Medium temperature too high
No. 20 Medium temperature too low
No. 30 Temperature difference selected is too high Correct temperature difference.
