7 PRINCIPAL DATA
7.1Readings on display
Normally the main display (Fig. 1.7) is shown, indicating the actual air outlet pressure and the actual compressor status. The key
<<Show More>> allows the operator to call up other information about the condition of the compressor (see section 3.5).
The readings below are valid when operating at reference conditions (section 7.5.1):
Maximum unloading pressure . . . . . . . . . . . . . . . . . . . . See section 7.5
Compressor outlet pressure . . . . . . . . . . . . . . . . . . . . . . Depends on programmed unloading and loading pressures
Interstage pressure . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Between 5.5 and 6.5 bar(e)
Pressure drop over air filters . . . . . . . . . . . . . . . . . . . . . Below 0.050 bar
Pressure difference over oil separator . . . . . . . . . . . . . . Below 0.8 bar
Oil injection pressure at compressor element 1 . . . . . . . Depends on programmed unloading and loading pressures
Compressor outlet temperature:
-for GR . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Approx. 29°C
-for GR Full-feature . . . . . . . . . . . . . . . . . . . . . . . . . . . . Approx. 26°C
-for GR W . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Approx. 25°C
-for GR W Full-feature . . . . . . . . . . . . . . . . . . . . . . . . . . Approx. 22°C
Compressor element 1 outlet temperature . . . . . . . . . . . Between 80 and 100°C
Compressor element 2 outlet temperature . . . . . . . . . . . Between 90 and 110°C
Cooling air inlet temperature (on GR) . . . . . . . . . . . . . Below 40°C
Cooling water temperature (on GR W) . . . . . . . . . . . . . Below 50°C
Pressure dewpoint (GR Full-feature) . . . . . . . . . . . . . . Approx. 3°C 1)
Pressure drop over DD filter (option) . . . . . . . . . . . . . . Below 0.35 bar
7.2 Programmable settings
A number of regulation settings (e.g. loading and unloading pressures), protection settings (e.g. shut-down level for the compressor
elements temperature) and service settings (e.g. oil service life) are programmable. The "User manual for Elektronikon regulator"
deals elaborately with this matter (section "Submenu MODIFY SETTINGS").
7.3 Settings of safety valve
15 bar(e) for 13 bar version
22 bar(e) for 20 bar version
Important
Some compressors with a specific approval may have valves with other settings. Always consult the data stamped on the valve
or consult Atlas Copco.
