4 Displays and control of the SK 2xxE
By the use of various modules for display, control and parameterisation, the NORDAC SK 2xxE can be
easily adapted to a wide range of requirements.
Alphanumeric display and control modules (Section 4.2) can be used for simple commissioning. For more
complex tasks, connection to a PC system and the use of NORD CON parameterisation software is
available.
As supplied, without additional options, the diagnostic LEDs are externally visible. These signal the actual
device status. 2 potentiometers (only SK 2x5E) and 8 DIP switches (S1) are provided in order to set the
most important parameters. In this minimal configuration no other modified parameter data is saved in the
plug-in EEPROM (See information for exchanging the EEPROM in Section 6). The only exception are data
concerning operating hours, faults and fault circumstances. This data can only be saved in the EEPROM
(memory module) up to firmware version V1.2. As of firmware version 1.3, this data is saved in the internal
EEPROM of the frequency inverter.
The memory module (plug-in EEPROM) can be parameterised independently from the frequency inverter
with the aid of the parameterisation adapter SK EPG-3H. Details of this are described in Section 6.4.

4.1 Diagnostic LEDs on the Frequency Inverter
The frequency inverter generates operating status messages. These messages (warnings, errors, switching
statuses, measurement data) can be displayed with parameterisation tools (e.g. ParameterBox - see
Section 4.2) (Parameter group P7xx).
To a limited extent, the messages are also indicated via the diagnostic and status LEDs.
