Confirmation key
Enter key: All changes in the display by
E
means of entered numbers or changes
via the "Yes/No" keys must be con
firmed with the Enter key; only then will
the device register the changes. The
Enter key may also be used to acknowl
edge a faulty reaction of the device; in
this case, the entry must be repeated
and re-confirmed with the Enter key.
The spontaneous system disturbance information in
the display can be acknowledged by pressing the
"No" key N and the quiescent display data called up
again. During the reset, the marshallable LEDs on the
front are illuminated so that these can be checked.

Operation with a PC

A PC (with MS WINDOWS operating system) and the
DIGSIr operating program enables the setting, star
ting of test sequences and retrieval of data, as do the
integrated keypad and display. However, the PC al
lows for the convenience of visualization on a monitor
and menu-guided execution.
All data can be saved on or retrieved from floppy
disks (e.g. for parameterization).
In addition, all data can be printed out on a printer.
In the case of operation with a PC, the applicable ma
nuals must be observed. The DIGSIr software is sui
table for the processing of all protection data. An
overview of operating programs and accessories (con
nection cable etc.) suitable for 7SD600 can be found
in section 2.3 Ordering data.

Prerequisites for operation

A code word entry is required for most operation
functions. This applies to all entries via keypad or ope
rator interface which affect the functions in the de
vice such as :
D Setting of function parameters (threshold values,
functions),
D Marshalling of trip relays, signals, binary inputs,
LEDs,
D Configuring of parameters for operating language,
interface and device configuration,
D Starting of test sequences.
Code word entry is not required to read out signals,
operational data, failure data or for the retrieval of set
ting parameters.
The entry of the code word as well as adaptation of
the PC interface is described in the preparation in
structions under section 5.3.
