Feeder Protection Relay
Technical Reference Manual - ANSI Version
Switching between setting groups via a digital input has a higher
priority than via the HMI or with the parameter V150.
The setting values can be altered via the HMI or with a PC provided with Relay
Setting Tool.
Before the relay is connected to a system it must be assured that the relay has been
given the correct settings. If there is any doubt, the setting values should be read
with the relay trip circuits disconnected or tested with current injection; refer to
Section 8. Check lists for additional information.
