Setting Binary Input Status
GRE110 can selected binary input detecting threshold voltage. The thresh hold voltage supports
control voltage of 24V, 48V, 110V and 220V.
The BI1 and BI2 can change three threshold voltage - 48 / 110 / 220V ( or 12 / 24 / 48V)
The BI3 to BI6 can change two threshold voltage – 110 / 220V (or 24 / 48V)
Note: The thresh hold voltage 48V (or 12V) of BI1 and BI2 is used for Trip Circuit Surpervision by
2 Binary inputs. See section 3.3.3.
The threshold voltage of 48-220V and 12-48 correspond by other relay model, respectively.
To set the binary inputs threshold voltage, do the following:
• Select "BI Status" on the "Binary I/P" screen to display the "BI Status" screen.
