Why is the red LED flashing 'OL' on my Perma Lubrication system?
- AAaron MclaughlinJul 27, 2025
The red LED flashing and the display showing 'OL' on your Perma Lubrication system indicates that the counter-pressure has exceeded 6 bar for an extended period. To resolve this, check for and remove any blockages to reduce the counter-pressure to below 6 bar. After resolving the blockage, press the SET button.
