Compressor - Compressed air alarm


The pressure (compressed air) in the compressor tank must be between 6 and 10 bar for the connected machines and valves to function correctly. When the pressure in the compressor tank is too low or if it does not work at all, the system can indicate a “compressed air alarm”. This can have several causes.

Watch the video to see step-by-step how to solve the alarm.

If you still have questions after watching the video or if you cannot solve the problem yourself using these instructions, please contact your installer.

1) Check that the compressor plug is connected.

2) Check if the on / off switch is in the "on" position.

3) Check that the thermal protection has tripped (press the black button to restart the compressor).

4) Check if the compressor is getting enough power from the socket (measure the 3 phases, they should indicate between 380 and 400 volts).

5) Check if no air is escaping from the automatic drain.

6) Check that the oil level is correct (the oil level is within the round circle of the indicator).

7) When you have found the problem and solved it or everything is found to be correct, you can turn the compressor back on and let it come up to pressure. The outgoing pressure should also be between 6 and 10 bar. You can easily adjust this yourself by turning the red knob.
