3 Displays and diagnosis
Various diagnosis possibilities are available, depending on the device. Operating conditions or errors are
visualised by means of LEDs. PC-based communication or the connection of a parameterisation unit is
possible via an RS232 interface (RJ12 diagnostic socket).

3.1 LED displays
Both the SK 200E frequency inverter and the CANopen modules provide LED status and diagnostic displays to
indicate the various statuses.
A differentiation into 3 categories is made
 Module or module-specific displays (S and E or DS and DE)
 CANopen-specific displays (CR and CE)
 Status displays for the additional digital I/Os of the module (D1/2 or DI1...4 and DO1/2)
The possible displays differ according to the device.
3.1.1 Device-specific display versions
3.1.1.1 SK 200E frequency inverter
LED S/E
The double LED S/E indicates the operating status of the
frequency inverter by change of colour and different flashing
frequencies. A device error is indicated by cyclic red flashing
of the LED. The frequency of the flashing signals
corresponds to the error number (Manual BU 0200).
LEDs BS and BE
The dual LEDs BS (BUS State) and BE (BUS Error)
indicate the status of the system bus communication module.
Various bus communication errors are indicated by means of
different flashing frequencies.
A detailed description of the LED displays of the frequency
inverter can be found in the main manual (BU0200).
