3.1 Diagnostic LEDs on the motor starter
The motor starter generates operating status messages. These messages (warnings, errors, switching sta-
tuses, measurement data) can be displayed with parameterisation tools (e.g. ParameterBox - see Section
3.2) (Parameter group P7xx).
To a limited extent, the messages are also indicated via the diagnostic and status LEDs.

NOTE
If there is active RS232 communication to a PC (NORD CON) or connected
control boxes, the device status cannot be displayed. In this case the LED indi-
cates that there is communication and in genera
l is therefore always "green".
In this case the red LED is switched off. If the current potentiometer is adjusted,
the green LED may also flicker due to the operating principle.
