Hi!
I have Mycenter HX300, 1999, Fanuc 16i.
I switched the machine and got the message (see photo).
I tried to find it in Manuals but no any reference.
What is the problem?
Where to dig?

I am guessing the machine has a Daikin type refrigerated oil cooler for the spindle.

It or the Kitamura itself is saying the oil is not flowing.

Yes, you are right.
It is Daikin cooler. But this cooler is working. It starts to work after the power on and not depends of switch on the center iyself.
I saw the green LED "COOL" switch on and switched off temporary to obtain the oil temperature constant.
The FAN on cooler sounds. Looks like the READY chain in contactor has problem, but I will check it tomorrow.
