Thermal3 Errorcode: [04413] The beam-pointing signal level is invalid

Thermal3 Errorcode


Service Information	While attempting to track the write laser(s), the beam-pointing control loop has found that there is either insufficient signal from the beam-pointing sensors or saturation of the beam-pointing sensors. As a result of this error, a fatal fault will be generated if the beam-pointing control loop fails to settle within 5 seconds. As a result of the fatal fault, the beam-pointing driver is shutdown and the system fault handler will shutdown the exposure head. Note that this error code is also returned to the host as an unsolicited fatal fault.
	After the beam-pointing control loop has settled, a warning fault will be generated on a single occurence. Note that this error code is also returned to the host as an unsolicited warning fault.
Operator Action	Call service.
Causes	Insufficient signal from the beam-pointing sensors. Saturation of the beam-pointing sensors. A hardware failure is corrupting the A/D samples.

Possible causes		This may occur when you are unable to turn the laser on or when you see a poor result from the script I_vs_P.spt. There may be a failure in the beam-pointing system.

Action		Follow the procedure for Troubleshooting Laser diode failure [error 05208] or invalid beam-pointing signal level [error 04413]. Upgrade to the latest TH3 firmware patch version 1.04.06. If this version is not yet available, contact Kurt Shelton at 604.329.3547.
