Important
- After pressing stop button (9), the compressor will run
unloaded for 30 seconds. The compressor stops after this
period. A start command during this period is ignored.
- After stopping, the compressor is prevented from restarting
within a programmable time (20 seconds). A start command
given during this minimum stop time will be memorized;
automatic operation LED (1) lights up. The compressor
will start when the minimum stop time has run out.
Example: ambient temperature 22°C, relative humidity 100 % and working pressure 20 bar(e). The minimum allowable
temperature at the outlet of the compressor elements is 85°C. Regulate the cooling water flow to obtain a temperature between
87 and approx. 92°C at the outlet of the compressor elements.
