Curtis 1228 LED DIAGNOSTICS
During normal operation, with no faults present, the status LED is steadily on.
If the controller detects a fault, the status LED provides two types of information.
First, it displays a slow flash (2 Hz) or a fast flash (4 Hz) to indicate the severity of the fault. Slow-flash faults are
self-clearing; as soon as the fault is corrected, the vehicle will operate normally. Fast-flash faults ("." in Table 2) are
considered to be more serious in nature and require that the key switch be cycled to resume operation after the fault
is corrected.
After the severity indication has been active for 10 seconds, the status LED flashes a 2-digit fault identification code
continuously until the fault is corrected. For example, code "1,4"-low battery voltage-appears as: one LED flash,
followed by a pause, then 4 LED flashes, and then repeats.
