Troubleshooting
Fault Codes
The drive controller has very robust fault code capabilities. Since most problems will result in setting a fault
code, whenever there is a problem with the drive system, the first thing you should do is check for fault
codes. There are three different ways to retrieve fault codes.
1. Counting the drive controller status LED flash code
a. The pair of LEDs built into the controller (one red, one yellow) produce flash codes displaying all the
currently set faults in a repeating cycle. Each code consists of two digits. The red LED flashes once
to indicate that the first digit of the code will follow; the yellow LED then flashes the appropriate
number of times for the first digit. The red LED flashes twice to indicate that the second digit of the
code will follow; the yellow LED flashes the appropriate number of times for the second digit.
b. The numerical codes used by the yellow LED are listed in the troubleshooting chart, which also lists
possible fault causes and describes the conditions that set and clear each fault.
2. Use the 1311 programmer.
a. The 1311 programmer will display all faults that are currently set as well as a history of the faults
that have been set since the history log was last cleared. The 1311 displays the faults by name. To
use the programmer, connect it to the serial port connector located on the left side of the machine by
the bank of contactors.
