CALIBRATION/SELF-TEST
The calibration values are determined after installation during the self-
test and during the calibration and stored on the SD card and the PCB.
On-site calibration is necessary when replacing:
Pressure sensor P1, B4 thermocouple humidity, fan wheel, micro SD
card and PCB together, use of different hinging racks, installation of new
air baffle, installation of hoods or Combi-Duo, customer complaints with
uneven cooking results, subsequent relocation
A self-test is necessary for new installations.
Start conditions:
Cooking cabinet sensor B1, control sensor B2, humidity sensor B4: <
40°C. In order to achieve the best possible calibration values, a closed
GN container should be inserted 20 mm deep with the open side down
in the middle in front of each fan wheel.
After a successful self-test, a flue gas analysis must be carried out for gas
units!
Calibration errors
Calibration errors either occur during the self-test or a manual calibra-
tion. The error number refers to the calibration step in which the error
occurred.
The most common calibration errors are:
n
Step 0 error start conditions:
B1, B2 or B4 over 40°C
Filling cleaner box with water taking too long, problem with solenoid
valve block or control solenoid
n
20: Differential pressure sensor faulty, loose cables
n
100: Fan motor speed detection faulty
n
200: Steam heating does not work, (check voltage, SSR, plug X20,
gas supply, energy optimisation)
