4 Operation
4.1 Start-up
Before starting up HYGROPHIL
®
H 4230, please check again that the follow-
ing conditions are met.
1. Power supply
– The mains voltage must correspond to the operating voltage of
HYGROPHIL
®
H 4230 and all components (gas sampling hose, filter,
accessories).
2. Gas sampling hose
– Mounted correctly
– All connections secure
– power supply cable connected
3. Compressed air
– Compressed air supply of at least 2...5 bar
– Compressed air stopcock initially closed
4. Water supply
– Sufficient water reserve
– Surfactant added
Once you have completed these checks, begin by opening the stopcock for
the compressed air supply.
Then switch on the supply voltage.
The equipment does not have a mains switch. It is switched on when the
supply voltage is switched on for the system as a whole.
4.2 Operating mode
Once the operating voltage has been switched on, the program version is
displayed and the equipment begins by carrying out a self test. The equip-
ment then undergoes a start-up phase, in which the measuring cell is filled
with water and the gas sampling hose is heated.
If you wish to check that the equipment is starting up as it should, open the
enclosure door on the right.
If you use the device under explosion-proof conditions with pressure-
reduction controller, you may open the enclosure only after having deac-
tivated the SILAS-controller functions.
To that follow the directions on page 43.
To begin with, all LEDs light up and a display test is carried out. After this,
the software version is displayed.
All measured value outputs are left at „0“ until the necessary measuring
conditions are met.
Once all the specified conditions have been set, the current measured val-
ues are displayed. At the same time, the measured value outputs jump to
the current measured values.
