In the factory default configuration, without additional options, the diagnostic LEDs are externally
visible. These indicate the actual device status. Two potentiometers (only SK 2x5E) and 8 DIP
switches (S1) are provided in order to set the most important parameters. In this minimum
configuration no other adapted parameters are stored in the external (plug-in) EEPROM. The only
exception is data concerning operating hours, faults and fault circumstances. This data can only be
saved in the external 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 variable frequency drive.
The memory module (external EEPROM) can be pre-parameterized independently of the variable
frequency drive using programming adapter SK EPG-3H.
