Current Converter Settings
Determining the Number of Primary
Conductor Runs
Determine the number of passes and the tap setting from the table
above. For example, if the current setting range is 2 to 5 A, there are
four passes and the tap setting is 20.
Pass the wires through the holes from the same direction. It doesn’t
matter which wires go through which holes.
Tap Setting
In tap setting, insert the setting screw into the required tap hole with
a screwdriver. After setting, be sure to replace the cover.
The following circuit can be used to check SAO-@ and SET-3@ characteristics.

Selecting the Current Converter
The current requirements of the motor determine whether the SET-
3A or SET-3B Current Converter should be used.
Single-phase Motor Use
The diagram below shows how to connect an SAO-@ Current Sensor
to a single-phase motor. There is a model available for use with a sin-
gle phase circuit.
Pass the required number of conductor runs through any two of the
three holes in the SET-3@ Current Converter. Even when wired as
shown in the diagram, the operating current will change, so it is nec-
essary to change the current SV as well.
Multiply the desired operating current by 0.77 to find the appropriate
current SV.
For example, if the desired operating current is 10 A, set the current
SV to 0.77 x 10 A = 7.7 A.
The SAO-@ is adjusted for 3-phase use, so verify operation in tests
with the actual load before operation.
