The motor controller provides diagnostics information
to assist in troubleshooting drive system problems.
The diagnostics information can be obtained in two
ways:
• Reading the appropriate display on the programmer
• Observing the fault codes issued by the panel
mounted Status LED.
4-2.8.1. LED Diagnostics
During normal operation with no faults present, the
Status LED is steady on. If the controller detects a fault
the Status LED flashes a fault identification code con-
tinuously until the fault is corrected.
NOTE: The Status LED can only indicate one fault at
a time. If multiple faults are detected, the
highest priority fault code flashes until it is
cleared.
With Fault Code Type parameter is set to 0, the status
LED uses the fault codes listed in
. Six sin-
gle-digit codes are used: 2, 3, 5, 6, 7, and 9.
For suggestions about possible causes of the various
faults, refer to
Troubleshooting Chart.
4-2.9. Programmer Diagnostics
With a programmer, diagnostics and troubleshooting is
more direct than with the LED alone. The programmer
presents complete diagnostic information in plain lan-
guage - no code to decipher. Faults are displayed in
the Diagnostic Menu, and the status of the controller
inputs/outputs is displayed in the Test Menu.
The following 4-step process is generally used for
diagnosing and troubleshooting an inoperative vehicle
using the programmer:
1.
Visually inspect the vehicle for obvious problems:
2.
Diagnose the problem:
3.
Test the circuitry with the programmer:
4.
Correct the problem.
Repeat the last three steps as necessary until the
vehicle is operational.
Refer to the
for suggestions covering a
wide range of possible faults.
