Using LEDs to Diagnose Problems
The LEDs on the front of the ET 200C modules provide you with initial in-
formation on that type of fault.
The tables below describe the meanings of the LED signals on the
ET 200C modules.

Explanation
RUN
Lit (green)
ET 200C; DI 8
DC 24V is in the RUN mode
(power supply switched on)
BF
Lit (red)
Either
The monitoring time has elapsed without the
ET 200C; DI 8
DC 24V being addressed
(because the connection to the IM 308-B is lost
or IM 308-B is set to STOP)
or
The ET 200C; DI 8
DC 24V was not
parameterized during startup or a restart.
