PM9605 Revision 1, 9605 Version 36.1.1
Appendix B: Error Codes
The 9605 will display the following error codes if it encounters a hardware or communication error that it cannot
recover from without help from an operator. An error code is displayed similar to the display of Setup mode
parameters. The last two rows of LEDs will display a BCD value which will indicate the error and the top two rows
will cycle Green, Amber, and Red which indicates that the 9605 is displaying an error code. The following table
will list all of the possible errors and list common causes for the error. After taking appropriate action to correct the
error, press any key to "reboot" the 9605.
Note:
Some of the errors below are very uncomon and in most cases will never be seen. Because
these errors are so uncomon they need to be discussed on an individual application basis.
If you encounter one of these errors please contact Quartech.
