Digital Input / Output Relay Interface
Installation Manual
6
Setting
The following settings are necessary to use Digital Input / Output Relay Interfaces.
• SW1 Address set switch
When two or more Digital Input / Output Relay Interfaces are used, set a different address for each unit
to avoid address duplication.
Assign addresses in ascending order.
CAUTION
•
When the SW1 setting has been changed, push the reset switch SW6. The new address setting is read.
•
Address of Digital Input / Output Relay Interface can be set independently from Energy Monitoring Relay
Interface.
• SW2 Operation mode set switch
• SW3 Test switch
• SW4 Test switch
These switches are not used during normal operation. Set zero (0) or “all
OFF”.
• SW6 Reset switch
When performing an address setting with SW1, push this reset switch after the address setting to read
the set value.
• SW7 RS-485 terminator resistor select switch
Terminator resistor of RS-485 must be set on Energy Monitoring Relay Interface.
When Digital Input / Output Relay Interface is used without Energy Monitoring Relay Interface, set it
[120 ohm] on Digital Input / Output Relay Interface with address SW1=1 and, set it [Open] on the other
Interfaces.
