Motor Protection Relay
Technical Reference Manual - ANSI Version
Group selection:
Switching between group 1 and group 2 is accomplished by means of a digital
*
input
Switching between setting groups through group selection has higher
priority than through group configuration.
The setting values can be altered via the HMI or with a PC provided with the 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 Check lists for additional information.
