Alarm: 117 SPINDLE HIGH GEAR FAULT
Haas Alarm Description:
Gearbox did not shift into high gear. During a change to high gear, the spindle is rotated slowly while air pressure is used to move the gears but the high gear sensor was not detected in time. Parameters 67, 70 and 75 can adjust the time-out times for troubleshooting only. Check the air pressure, the circuit breaker CB4 for the solenoids, and the spindle drive. In Diagnostics, check the status of discrete inputs Spindle Hi Gear and Spindle Low Gear. One bit should read 0, the other a 1, then the bits should change status when a gear change has completed.
