7SA511 Line Protection Relay Product Description

2.5.3 Multiple Parameter Sets (optional)

Another optional feature of the 7SA511 relay is the ability to program multiple parameter sets (relay models 7SA511*-**A5*-**E/F/G*). This feature, called parameter changeover (PCO), provides four parameter sets—identified as A, B, C, and D—in addition to the original, default set. System settings and relay protection settings (addresses 1000 to 4000) can be uniquely defined for each parameter set. You can also copy data from one parameter set to another, including the original set.

Only one parameter set is active at a time. You can change the active parameter set during relay operation (provided no protection functions are picked up) using the operator panel or through the binary inputs. If the relay is connected to a PC via the front port, you can use DIGSI® software to change the active parameter set.
