VF-2ss coolant breaker

Every couple of days the coolant pump will kick the breaker off. Why doesn't the machine alarm out? It will continue to run dry. Is there a parameter to make the machine alarm out when the coolant pump pops the breaker?
Not a big problem because I'm right there but it makes me hit optional stop when I go to lunch or do something else.

I do not know the answer. However, it might be worthwhile taking the coolant pump out to discover if there is poor connection or perhaps some swarf stuck in the impeller that would raise the motor load somewhat above normal.

It is also a good idea to check with your Haas dealer. One to two years ago Haas started using a different motor on the coolant pumps and this motor has a tendency to pop the breaker very frequently. Now I think there is a slightly larger capacity coolant breaker available to prevent this happening.

Thanks. I'll try the connection idea. Just changed the coolant and cleaned out the tank. Checked the pump then. Wide open and clean. No change in the frequency of occurance after the cleaning that I could tell.
