hey all, i have an Okuma 852v mill that is controlled by a fanuc 31i. today neer the end of a drilling cycle i got this alarm: EX3019 COOLANT SUPPLY ABNORMAL. the coolant tanks are full of fresh coolant and everything seemed to be working fine up until a few min ago. i AM running a chip blaster thru spindle, and at the time it alarmed out i was runnning 500psi thru spindle. i am unable to find this alarm in any of my books and i am unable to reset it. any help would be great guys and gals. thanks in advance!

The float switch in the coolant tank is stuck in the down position. It may be buried in chips.

found some sort of breaker/relay in the back of the chip blaster that had tripped. re-set that and all seems to be working fine. could the float switch have tripped this??
