4.4 Diagnosis LED's

4.4.1 LED 1V8, 3V3 und 5V1

These LED group indicates the presence of the different supply voltages. For accurate operation
the presence of all voltage levels is essential. If one or more of these LED's are off, this indicates
a serious damage.

4.4.2 LED BL

The LED indicates the correct program execution flow with a flash rate of 1Hz. If the LED keeps
off the user program is not executed. In this case the interface board either is malfunctioning, the
Firmware is missing or the Bootloader mode for firmware download is activated.
4.4.3

LED H16 DIAG

The LED indicates possible failures by flashing with two different frequencies. If the LED is off no
failure is recognized by the controller logic.
If more than one failure is recognized always the failure with the lowest group / code will be
signalled.
