3 Display and operation
In the delivery condition (without technology unit) 2 LEDs (green/red) are visible externally. These indicate the
current status of the device.
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
error (Section. 6).
3.1 Modular modules
By combining different modules for display, control and parameterisation, the NORDAC SK 5xxE can be easily
adapted to various requirements.
Alphanumerical display and operating modules can be used for simple start-up. For more complex tasks,
various connections to a PC or an automation system can be selected.
The
technology unit (Technology Unit, SK TU3-…)
is connected externally to the frequency inverter and is
therefore easy to access and replace at any time.

WARNING
Modules should not be inserted or removed unless the device is free of voltage. The slots may
only be used for the applicable modules.
NOTE:
Installation of a technology unit
separate from the frequency inverter
is not possible. It must be
connected directly to the frequency inverter.
Further detailed information can be found in the Options manuals.
