Haas Alarm: 119 OVERVOLTAGE – Incoming line voltage is above maximum. The servos are turned off and the spindle, tool changer, and coolant pump stop. If this condition persists, an automatic shutdown begins after the interval specified by Parameter 296. Under certain conditions, SMTC Recovery must be performed to clear the alarm. Incorrect power or loss of power to MOCON can also cause this alarm. For office machines and all other machines that use the 320V power supply, Parameter 315 bit 8 (Mini power supply) needs to be set to 1.
