Trumpf Laser 3030
(OP)
Hello, can anyone help me with a problem that I am having with a Trumpf 3030 laser.
We are experiencing a problem with the machine, it is saying a No coolant flow in the aluminum cooling circuit but when we check the flow sensor (replaced it 2 times) it is still the same. When we checked the hose going into the flow sensor, water is coming out. We have tried adjusting the flow sensor to read only a very small amount of water but the error is still popping up.
Anyone got any ideas on this problem?

RE: Trumpf Laser 3030
could you disconnect the return line from that circuit, let it flow into a bucket for a known time, see if it actually flowed the specified amount?
(yeah, that's crude - but you could have a restriction in the circuit somewhere -- maybe the flow sensor is telling the truth?)

Als if you've done a water change recently, and cleaned the cathode cups, you may have a small piece of debris jamming the impeller on the flowmeter
