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