Operation and control
A test under real conditions helps you set the operating pressure needed to dehumidify
the compressed air.
To change the operating pressure, pull the
plastic cap under the manometer of the
pressure controller down until you see the
orange sheathing (Fig. 12).
►
Turn the cap clockwise to reduce the
operating pressure;
►
Turn the cap counter-clockwise to in-
crease the operating pressure.
Increase or decrease the operating pressure
with the pressure controller until you've
reached the smallest humidity amplitude
possible (Fig. 11).
When you change the operating pres-
sure, you will not immediately see this
change in the humidity range graph. Let
the appliance run with the new settings
for about 15 minutes. Then the adjust-
ment will show on the graph correctly.
The operating pressure for compressed air dehumidification set in the factory is 0.2 bar.
This is enough to achieve a certified dehumidification of 10 % humidity at 10 °C under
laboratory conditions. You can adjust the operating pressure after testing the appliance
under the operating conditions with parameters of your choice. The following param-
eters may have a negative effect on constant regulation:
►
User-defined composition of the temperature-humidity parameters
►
User-defined dehumidification rate
►
Humidity that was introduced into the chamber
Manually readjust compressed air dehumidification if you use the appliance for a differ-
ent purpose.
We do not recommend using the compressed air dehumidification function in an ap-
plication range other than the one described above.
4.4 Example day-night simulation programme
With the help of the MEMMERT software AtmoCONTROL, programme-controlled opera-
tion of the appliance is possible. On the following page, you see an example as to how
day/night cycles can be simulated.
You must read the software manual AtmoCONTROL in order to acquaint your-
self with the programme.
