Hey guys we have an issue with an alarm maybe yall will know whats wrong, the alarm is :543 alarm b axis lube pressure on confirmation.Its a 5020M controller on a cadet 4020.Anybody have any suggestions on what I can do to fix this?Thanks in advance
This alarm comes from axis lube unit pressure switch. Check the switch itself to make sure it is correct and You need to find oil leak. Possible causes:
1. Most likely, recent mechanical intervention or chip collection caused some lube pipe failure
2. Lubrication pump motor dead.
3. Pressure switch, intermediate relay or controller input, easy to quick check. Less likely.
Temporary You can cheat the sensor signal - together with pump motor start command You close the contact simulating pressure switch. It's not a solution, it's just to complete current job before thorough inspection of lubrication pipes.
