Siemens 7SA511 manual Copying Parameter Sets

7SA511 Line Protection Relay Programming the Relay

The relay always operates with the active set of parameters (see section 5.8.2) regardless of which set is being displayed or configured.

Copying Parameter Sets

Prior to activating the parameter changeover feature, the parameter values are display without a parameter set ID prefix. In reality, the relay is operating with parameter Set A and any changes made to the settings will be made to Set A. The factory preset for the active parameter set when parameter changeover is activated is Set A. Therefore, if programming changes are made prior to activating parameter changeover, there will be no undesirable changes in the operation of the relay when parameter changeover is initially activated.

All four of the available parameters sets are initialized at the factory the same set of default parameters identified as the “ORIG.SET.” This set of parameters is permanently stored in the read-only memory of the relay. If, after making setting changes, it is necessary to restore the relay to the factory default settings, this can be done by copying the ORIG.SET to any or all of the four parameter sets.

A selectable set may also be initialized by copying another sel ctable set. Table 5-5 contains a list of the available copy opti ns. To perform a copy, access the address corresponding to the desired copy function. ForORIG8512Copy?example:.SET->SETC

Press the YESkey. The second line of the display will indicate “IN PROGRESS” followed by “SUCCESSFUL” after a successful copy operation. Press Enterto clear the message. The relay remains in programming mode. (To exit programming mode see the following Note.)

Note: To properly save the copied parameter set, use the navigation keys to leave the 8500 address block. When you do this you will get the “SAVE NEW SETTINGS” message.
