APPENDIX B: Status Codes
Status Codes
Table B-1 lists the status codes and messages that can be produced by the InSight
®
X3
™
laser system. Most are self-explanatory and many errors can be corrected by the user.
In the event the error cannot be corrected or the action required to correct the error is not
known, contact your Spectra-Physics service representative. However, before you call,
write down the code and its description.
The READ:AHIS? command reports the most recent 16 codes from the system, with the
most recent code listed first. These codes along with a short description are also shown
on the LCD display on the front panel of the IPS-300 power supply, as shown in
Table B-1.
The status types shown in the table below are:
Status — System is functioning normally
Warning — System is functioning normally, but user action is suggested.
Fault — Laser diodes turn off and the shutter closes. User action is required.
Critical Fault—Laser turns off and cannot be restarted without cycling AC mains
power.
