The Broken Tool Detection (BTD) is a feature that detects the length & captures an image of a tool before and after use. With a noticeable difference in length, then ALARM 9300 Broken Tool will be triggered forcing the BTD tab to pop up with before and after images. 

For the most accurate results of the Broken Tool Detection feature, make sure the tool is positioned horizontally in the middle of the grid lines on the screen— the Region of Interest (ROI). The ROI value determines how much of the image the system is detecting. 

This troubleshooting guide will explain each alarm and show ways to troubleshoot the Broken Tool Detection system. 

NOTE: To learn more on how to operate the Broken Tool Detection feature, refer to the Broken Tool Detection - Operation reference document for more information. 

ALARM 9300 Broken Tool will be triggered in the event of a broken tool. 

NOTE: A box will appear around the reference and current tool length. With software version 100.23.000.1110, a green box will appear around the tool. With software version 100.23.000.1200 or higher, a lilac box will appear around the tool with a warning symbol [1].

Due to the alarm, the tool cannot be commanded back into the spindle via M06, but can be commanded back into the spindle via [ATC FWD].

Once the tool is inside the spindle, inspect for breakage and replace as necessary. If the tool is not broken, take an error report [SHIFT] - [F3] of the machine to send to the local HFO. 

The following only applies to Software Version 100.23.000.1110:

ALARM 9301 Broken Tool Detection Fault will be triggered by a hardware issue when the control is unable to communicate with either the A62 board or camera. This alarm will only appear when the program calls for a tool change and the Tool Table is toggled to detect a broken tool, but struggles to find a connection with the BTD system. 

To troubleshoot this alarm, verify that the camera is connected to the A62 board & that the A62 board is connected to the BTD A62 PFDM PCB. Power cycle the machine if the issue continues. 

The following only applies to Software Version 100.23.000.1200 or higher:

ALARM 9301 Broken Tool Detection Fault will be triggered by a software issue. There was an issue with Broken Tool Detection software that resulted in the control not being able to run Broken Tool Detection. 

To troubleshoot this alarm, press [RESET] to continue. Power cycle is necessary. If the issue still persists, then take a [SHIFT] - [F3] and send the results to your local Haas Factory Outlet for further review. 

The following only applies to Software Version 100.23.000.1200 or higher:

ALARM 9302 Broken Tool Detection Board Communication Lost [1] will be triggered by a hardware issue when the control is unable to communicate with the A62 board or when the A62 board is faulty. 

To troubleshoot this alarm, verify that the A62 board is connected to the PFDM PCB properly. Make sure that the A62 board cable functions as excepted. Power cycle the machine if the issue continues. 

The following only applies to Software Version 100.23.000.1200 or higher:

ALARM 9303 Broken Tool Detection Camera Communication Lost [1] will be triggered by a hardware issue when the control is unable to communicate with the camera or when the camera is faulty.

To troubleshoot this alarm, verify that the camera is connected to the A62 board and that the A62 board is connected to the PFDM PCB. Use T-150 Cable Tester tool to make sure that the camera cable functions as excepted.  Refer to the Haas Cable Tester Kit – Instruction procedure.

Power cycle the machine if the issue continues.
