Some former coworkers, with a company that folded, aquired one of the Okuma 4-VMCAE mills, that we used, from the auction. When they got it set, and fired it up, a 596b alarm came up. They did not get the alarm code manual (there is one on order).

The alarm says "spindle head cooling" All of the cooling systems are working. Is it just a sensor?

How can I get this alarm cleared?
