LTBRZ3-C series | INSTRUCTIONS MANUAL
When a fault is detected, four consecutive led flashes indicate the presence of one or more error
conditions. The four flashes correspond to four possible error conditions, named E0, E1, E2 and
E3. The flashes timing diagram is reported in the diagram below. Each flash lasts for 0.5" (500ms)
and has a period of 1" (1s). The four flashes train is repeated every 6" (6s). The first flash
corresponds to E0 (error0), the second to E1 (error1) and so on. If the E0 flash is green, there is no
error, if red, error is present.
Example 1:
1 st flash is green
nd
2 flash is red
3 rd flash is green
4 th flash is green
This means that only error1 (E1) has been detected.
Example 2:
1 st flash is red
2 nd flash is red
3 rd flash is green
4 th flash is green
This means that two errors have been detected, error0 (E0) and error1 (E1).
The following table lists how errors are coded.
Error code
E0 Driver overtemperature detected
E1 Led board overtemperature detected
E2 Supply voltage error (undervoltage shutdown occurred)
E3 Power supply failure detected
