Alarm: 151 LOW THRU SPINDLE COOLANT
Haas Alarm Description:
For mills with Through the Spindle Coolant only. This alarm will shut off the coolant spigot, feed, and pump all at once. It will turn on purge, wait for the amount of time specified in Parameter 237, and then turn off the purge. Check for low coolant tank level, any filter or intake strainer clogging, or for any kinked or clogged coolant lines. Verify proper pump and machine phasing. If no problems are found with any of these, and none of the coolant lines are clogged or kinked, call your dealer.
