MONITORThe UNI-WIRE SYSTEM is a highly reliable wiresaving system. Data trasnsmission is performed
using two signal wires (D and G), and the system
uses a simple concept and structure which makes
long-distance data transmission possible. The"H-feature" has disconnection detection function
point indicator function that further enhances thesafety and flexibility of the UNI-WIRE SYSTEM.

Method of abnormal condition detection by H-feature
To detect the disconnection in transmission lines, the
UNI-WIRE SYSTEM exchanges the ID numbers
between the Control Unit and the respective Terminal
Units on the transmission line, and continually monitors whether transmission is successful.
> The Send Unit (controller side) sends the ID numbers to the Terminal Units (terminal side).
> When a Terminal Unit receives the ID number thatmatches its own ID, it sends back a confirmation
response to the Send Unit.
> If the Send Unit does not receive a confirmaion
response for an ID number, it judges the that thecorresponding Terminal Unit is disconnected.

OPERATION
Starting Point for Operation
Perform the following procedure when first insralling the UNI-WIRE W series or

NOTE modifying it. An inproper usage may effect the system performance(e.g.; thedisconnection can not be detected; etc.)

5) Check the number ofconnected Units.

1) Turn on the power.
Check wiring and connections are correct before
turning on the system power source.

6) Check the ID numbers.

2) Check the lamps on the Send Unit.
The POWER and ER4 are on.
SEND flickers.
3) Sizing(SET switch)
Push the SET switch with a pin or pen to perform
Sizing. This shall be done for all Terminal Units inorder to register its ID number.

Trouble and Indication
When the disconnection troubles such as below occur, the disconnected ID numbers are indicatedon the MONITOR display of the Send Unit by pushing the DISPLAY switch. In case of the centralized
power system as shown below, the Send Unit SDW-H2 is capable of verifying the connections not
only in the transmission line but also in the power supply line.
