Siemens 7SA511 manual Configuration Settings, Procedure for Configuring the Logical Functions

7SA511 Line Protection Relay Programming the Relay

5.19 Configuration Settings (6000)

The configuration settings tell the relay what action to take and how. Configuration is the process of assigning one or more logical functions to each of the physical input/output (I/O) units. The relay has a large number of predefined logical functions. Each logical function has a unique three digit function number (FNo) assigned to it. A complete list of logical functions that can be configured is provided in Reference G, “Input/Output Functions,” in function number order.

If you change any of the configuration settings, the relay microprocessor will automatically reset and restart after the new settings are saved.

5.19.1 Procedure for Configuring the Logical Functions

To make configuration changes, the relay must be placed in programming mode using the password as described in section 5.3.2. Follow this example procedure to configure an I/O unit in the 7SA511 relay.

Note: There are two qualifiers on the functions assigned to for binary inputs (NO and NC) and LED indicators (n and nm). Refer to sections 5.19.3 and 5.19.5, respectively, for further instructions on selecting the correct mode of operation.

1.Select the address number of the I/O unit you want to configure and enter the relay password (see section 5.3.2). The display will appear similar to this example, which shows address

number 6204RELAY4620. 4SIGNAL

2.Press the Fkey. An “F” will display over the solid bar following the address number in the display.

3.Press the key to complete the change to the function selection level. The address number in the display is replaced with a 3 digit index number 001, which is automatically assigned to the first function. As shown in the example below, the second line of the display contains an abbreviated>VTmcbTrip001RELAYdescription of the4assigned function.
