Selftest - Manual humidity calibration
Start
To start the Self test will start the temperature of B1, B2 and B4 must be below 40°C (104°F).
Additionally 1 flat and closed GN container (max 20mm) shall be inserted into the cabinet with the opening facing
down at a height center to the fan wheel. (201 - 202: 2 fan wheels = 2x GN containers)
SCC: To start, follow the display menu
CM_P: To start, press the „START“ key
During step 200 of the self test the boiling point will be calculated and stored.
Steam production will be active until steam saturation in the cabinet until the quenching sensor B2 reaches 80°C
(176°F). When additionally B4 is within 3°C of the cabinet sensor B1, the pcb will memorise the temperature
measured by B1 as the boiling point temperature and calculates the installation height.
(A maximum time of 30 minutes is allowed to achieve the boiling point calculation -- Service 200)
» After Self test only switch off the unit when the display shows: „Self test successful“
Should at a later point in time the unit be reinstalled at a altitude more than 300 m different to the original instal -
lation height, a new self test should be initialized in order to calculate the new boiling point.
Such re-initialization can be be done in Basic settings, self test.
Manual humidity calibration:
Condition: unit cold (below 40°C - 104°F), 20mm closed container at center of fan wheel (201-202: 2x GN)
Manual calibration has to be done after:
Disassembly of motor or fan wheel, P1, B4, changing air baffle or later installation of an UltraVent or unit exhaust
hood as well as later installation as the lower unit of a Combi Duo.
Note: In this case do NOT run a new selftest, as otherwise the boiling point and the gas blower speed and the
reference volume of the steam generator will be overwritten!
CM_P: new Self test after changing PCB or re- installation at different altitude:
Should at a later point in time the unit be reinstalled at a altitude more than 300m different to the original instal -
lation height, a new self test should be initialized in order to calculate the new boiling point.
Such re-initialization can be be done in Basic settings, SE20
As all humidity values and boiling point are stored on the PCB a new self test must be started after changing the
PCB.
Start Self test
To change from 0 to I or vice versa set desired status with timer dial (0= sefl test disabled, I= Self test enabled),
keep time key pressed and press core key for 1 sec, release core key before releasing time key,
NOTE: Gas units: Flue gas analysis must be done after the self test!
CM_P: Manual humidity calibration:
In service mode set dip switch 2 while the unit is switched on. Select „cali“ with timer dial and press „START“
Duration of self test
Duration of self test is appr. 45 minutes for table units and 65 minutes for floor units.
In case a Ultravent is connected to the unit this time will be extended for up to 20 minutes. Installing a p-trap at
the drain reduces this effect.
Calibration is appr. 5 minutes shorter compared with self test.
