3 Displays and control
As delivered, without the technology unit, 2 LEDs (green/red) are visible externally. These indicate the
actual device status.
The
green LED
indicates that the mains voltage is present and operational, while a flashing code that
increases in speed shows the degree of overload at the frequency inverter output.
The
red LED
signals actual error by flashing with a frequency which corresponds to the number code
of the fault (please see chapter 6 "Operating status messages").

3.1 Modular assemblies SK 5xxE
By the use of various modules for display, control and parameterisation, the SK 5xxE can be easily
adapted to a wide range of requirements.
Alphanumerical display and operating modules can be used for simple commissioning. For more
complex tasks, various connections to a PC or an automation system can be selected.
The
Technology Unit (Technology Unit, SK TU1-...)
is connected externally to the front of the
frequency inverter and is therefore easy to access and replace at any time.
