Continue with step 10
Measurement:
Offset Diff. pressure sensor P1
• Heating: OFF
• Motor: OFF
• Humidity ap: Closed
P1 or 12V power supply to P1
Controlling with all 4 fan speeds:
Steady signal of rpm and pressure
• Heating: OFF
• Motor: ON
• Humidity ap: Closed
In diagnostic mode: P1, B4, rpm
Measuring at all 4 fan speeds:
Calibration value: cold cabinet
• Heating: OFF
• Motor: ON
• Humidity ap: Closed
Überprüfung im Diagnoseprogramm: P1, B4, rpm
Step 20 and 30 will run 1x for each rpm setting!
Filling cabinet with steam until B2 sensor reaches
80°C (176°F)
• Heating: ON
• Motor: OFF
• Humidity ap: Closed
Steam heating elements, SSR, quenching sensor
Stand-by in steam saturation
• Heating: ON
• Motor: ON (lowest speed)
• Humidity ap: Closed

Calibration at the customers site must be done under the following conditions:
Changing the pcb, extrenal EEPROM, B4 humidity sensor, Pressure sensor P1, replacing the
air baffl e or divider plate between the 2 fan motors of a fl oor model, fan motor, detaching of the fan wheel and
installation of the appliance above 1000m (3000ft) above sea level or below sea level (dead sea).
Basic condition Cabinet sensor B1 Quench. sensor Humidity sensor
Temperatures: B1 <40°C B2 <45°C B4 < 40°C
Basic condition Heating: OFF Fan motor: OFF Humidity fl ap: Closed
Hardware: Side panel must be fi tted; Unit must be clean, but may be wet
In order to achieve the best possible calibration values, insert
2 GN-container 20 or 40 mm deep with the opening facing downwards
in 61 and 62 units into rail 2 and 5
in 101 and 102 units into rail 3 and 7
in 201 and 202 units 3 GN container into rail 3, 10 and 17
