Burford 2000 - Seven Segment LED Error Codes

112 Chapter 7
 Seven Segment LED Error Codes
Mounted on the edge of the CPU board inside the Main Enclosure is the seven segment
LED which can display all of the numbers and most of the alphabet, one character at a
time. This device is used to display various codes that give the Servo Tyer status and
may be helpful in troubleshooting. The codes are divided into three categories: counter,
status, and error. The CPU keeps a running count of the number of packages tied by the
Servo Tyer. During normal operation, the letter 'C' will be displayed followed by this count.
Status codes begin with the letter 'H'. These codes give general information pertaining to
the current Servo Tyer status. Error codes begin with the letter 'E'. These codes will give
information pertaining to a Servo Tyer fault. For more information on how to use the error
codes to troubleshoot the Servo Tyer refer to pg.113.
The LED will flash the codes in the following manner (the dashes are for separation of
characters for example only the LED will not show dashes).
Counter Codes: C-1-8-6
Status Codes: H-0-0-1
Error Codes:
E-1-1-1
Error codes 111-146 deal with the electrical issues a motor might have. If one of these
error codes is displayed the main areas to check are the fuse, encoder, prox and motor
for the motor that the error code is indicating. Flow Charts 4-11 thru 4-26 deal with
troubleshooting these error codes.
Once an Error Code has been displayed, it will be repeated until a new code replaces it
or power is turned off. Generally, you will have to home the Servo Tyer or tie a package
before the code will be removed. The following is a list of the codes and their descriptions.
