LED Colour Codes
The bicolor LED on the central unit is used as a raw diagnostic information about the system status. It
can be useful in the case that the iflex refuses terminal communication - otherwise the terminal is a
much more powerful diagnostic tool.
During initialization (after reset) the LED shows some of the initialization steps, so if the reset
procedure hangs, it is easier to find out where. The cycle is:
 RESET: red+small red (for approx 5 us)
 Wait for RAM: green (for approx 200 ms)
 Clear RAM: yellow (for approx 1 s)
 CRC-Check System program: light yellow (2.5 s)
 Init RS232/RS485 : yellow (1 s)
 Start RTOS: green (0.5 s)
After start of RTOS the LED toggles all 1 sec between dark/green/yellow/red.
So you can detect
- is the power supply ok?
- is the iflex in the reset procedure, hanging somewhere or is the Operating system running?
You cannot be sure if the LED shows running Operating system that all necessary tasks of the
System program are running correct, too. That has to be made sure via terminal commands.
