Additional specific information:
Pre condition before Self test and Calibration
Remove all accessories, packing material and fastening aids from the cabinet.
Temperature of cooking cabinet sensor B1, control sensor B2 and humidity sensor B4 is below 40°C (104°F)
closed GN container in front of fan wheel inside cabinet
door contact closed and left side panel closed
Component test
Test of:
Drain valve M7, Solenoid Y1, SC Pump M4, level electrode S2, CDS Sensor, Solenoid Care Y4, Solenoid Moistening
Y3.
P1, Motor, Heating etc are tested during the following humidity calibration steps

Function possible
calibration error
message
reason for error - remedy
0 ready for calibration Any indicated error relates to the corresponding
calibration step.
e.g. error 10 will be indicated, when the condition for
calibrations is not given.
Reason: B1, B2 or B4 is above 40°C (104°F)
e.g. error 100 will be indicated if motor or fan wheel is
blocked,
2 steps for each speed and direction, e.g.
100, 210, 301: running fan motor does not reach
constant speed , check motor and fan wheel
101, 211, 302: P1 value at this speed out of range
e.g. error 200 is indicated, when B2 in the control box
will not reach the necessary 80°C (175°F) to determine
the boiling point in the allocated time.
Install p-trap in drain and fill with water.
Reason: e.g. high negative pressure by exhaust hood
above the unit is permanently cooling the control sensor
B2 via the venting pipe; install p-trap at drain connec -
tion.
These errors are indicated during the respective calibra-
tion step is running.
After solving the problem the Self test must be started
again.

Caution: Steam
The following self test or calibration errors have occured:
10 unit too warm, cool down
20 Power supply 12V dc to P1 is missing
100 Motor blocked or defective
200 Unit not heating (energy optimising active), unit set to 1/2 energy or drain open.
Note gas units: After self test a flue gas analysis must be done.
