Configuration
Current transformer ratio
You can assign each of the 4 current
transformer inputs its own current transformer
ratio. A current transformer ratio of 5 A/5 A
is programmed in the factory for all 4 current
transformer inputs.
You can program current transformers with the
same current transformer ratios in addresses
000 and 001. Program current transformers
with different current transformer ratios in
addresses 010 to 041.
A change in current transformer values in
address 000 or 001 overwrites the contents
of addresses 010 to 041 with the current
transformer values from addresses 000 and
001.
A change in current transformer values in
one of the addresses 010 to 041 deletes the
current transformer values in addresses 000
and 001.
