Monitor the series of blinks to determine the fault code. Count the first and last series of slow
blinks, and disregard the series of fast blinks between the slow series.
Module Error Codes
When the status LED blinks red, it signals that a hardware or software fault has been detected
and it reports the error via a code. This code is a two-digit fault code signaled by a flash
sequence. First, the LED begins the sequence with 10 rapid flashes. Then the LED signals the
first digit of the code by a number of slow flashes. Approximately two seconds after the LED
displays the first digit, the LED displays the second digit. This sequence repeats itself until the
module is either reset or replaced.
The following table lists controller fault codes relating to the interface module.
IMPORTANT
The interface module will flash the indicator lights as shown in the
Module Error Codes table. The controller may fault even though the
module does not.
