A.3 Relay Front Panel Navigation

The basic menu structure flow diagram is shown in A.66 after the following relay front button description. This diagram shows the main modes of Display, Settings Mode, Instrument Mode, Fault Data Mode and Control Mode. Relay programming procedure is described in A.4

When the relay leaves the factory all data storage areas are cleared and the settings set to default as specified in the settings document.

When the relay is first energised the user is presented with the screen description as shown in A.2

A.5 Communication Port

To set the relay using a communication port the following is required:

PC with Reydisp Evolution Version 7.1.5.6 or later Installed. (This can be downloaded from the Siemens website and found under the submenu ‘Software’) This software requires windows 2000-service pack 4 or above, or windows XP with service pack 2 or above and Microsoft.NET framework for tools.

The relay can be connected to Reydisp via any of the communication ports on the relay. Suitable communication Interface cable and converters are required depending on which port is being used.

A.5.1 Front USB connection

To connect a pc locally via the front USB port.

A.5.2 Rear RS485 connection

To connect a pc locally via the rear RS485 port.
