Programming Example
Changing default logic is sometimes required to match the protection requirements of the system.
Additionally, elements must be enabled and operating settings set. This example demonstrates how to
configure typical nominal settings and program the 50-3 instantaneous overcurrent element. System
nominal quantities are set to 69.3 volts and 3.6 amps. The 50-3 element is set for a 5.62 amp pickup and
a 30 second time delay. Additionally, the element pickup output is logically wired to output 4 and a user
alarm.
