LED’s (Operation Status and Messages)
The LED’s located on the top side, a green LED (Bus Run) and a red LED (Bus Fail), serve for monitoring of op-
erating status. For setting the address are two rotary coding switches located on the top next to the LED’s
BUS RUN
GREEN
ON
= Ready
OFF
= Supply voltage not provided
Flashes cyclic
= Slave has no cyclic data exchange with PROFIBUS-DP-MASTER
Flashes irregular
= start: Missing or faulty configuration
Runtime: Host watchdog- time error
BUS FAIL
RED
ON
= unrecoverable Converter – Fault
