Explanation of SAO-SU Contacts
1. The contact is NC (between terminals 4 and 5) when the motor is not started.
2. The contact is NO (between terminals 5 and 6) when the startup pushbutton is
pressed and a current larger than the reset current flows.
3. The contact is NC (between terminals 4 and 5) when the motor current is less than
the operating value (i.e., undercurrent).

Operation
■ Settings
Current Sensor Switch Settings
Current Scale Multiplying Factor Decal
Determine the current scale multiplying factor corresponding to the
current SV range obtained from Table 1 and paste the current scale
multiplying decal to the current sensor. For example, when the current
setting range is 2 to 5 A, the decal no. is 0.5.
Setting Operating Current
SAO-R/Q
LED Indicator
The LED indicates that an overcurrent
has occurred and the relay is operating.
Setting Operating Time
Set the time setting knob to the required
time. The operating time is equal to the
time scale value times the setting on the
time changeover switch. For example, if
the time scale value is 6, and the time
changeover switch is set to 4, the
operating time is 24 s. For the SAO-R,
this is the operating time in the event of a
600% overcurrent. For the SAO-Q, this is
the operating time in start-up mode.
There is no operating time SV for the
SAO-S.
Set the current setting knob to the required current
value. The setting value is indicated by the product
of the scale value and the multiplying factor as
shown in the following table. The required trip current
can be obtained directly by means of the current-setting knob.

Note: The current setting range is determined by the number of times the conductors to the SET-3@ are passed through and by the setting tap of
the SET-3@. The current scale values are always 4 to 10 A. Therefore, attach the included current scale multiplying factor label to the SAO
that matches the current range.

Determine a current scale multiplying factor that matches the steady

label number is 0.5.
2. Setting the Operating Current

SAO
Precautions
On Operation
Connections
Use a commercial frequency power supply only for the control power
supply.
Make sure that the polarity is correct when connecting the Current
Converter and Current Sensor. It is not necessary to consider polarity when using a DC control power supply.
The SET-3@ Current Converter is designed for use with a single SAO
Current Sensor; do not connect two units to a single SET-3@ as in
figure 1 below (even if a diode is included in the circuit).
If the current transformer has sufficient capacity, the circuit in figure 2
is acceptable.
Determine the necessary number of conductor runs from the table
Selecting the Current Converter in the Operation section. Pass the
wires through the holes from the same direction. It doesn’t matter
which wires go through which holes.

Verify operation by turning on the control voltage and pressing the

It is possible to check whether SAO-@ and SET-3@ characteristics
are correct or not with the test circuit shown on page 9.

Mounting
When installing with an 8PFA1 connecting socket, first fasten the
socket firmly to the panel with screws, then plug in the relay and
secure it with a hook. Leave at least 30 mm of space between the
relays for the hooks.
Back-connecting sockets can not be used.

Q&A
Q
What is the procedure for using the SAO with a single
phase?
The following describes the single-phase operating
procedure for the SAO. Models for single-phase circuits,
however, are also available. Refer to [email protected]
Connection Procedure
Run the primary wires through any two of the three holes on the SET3 the number of times specified for the SET-3@.
Q
Can two SAO Current Sensors be used connected to one
SET-3@? If not, can a diode or other device be inserted?
It is not possible to connect two SAO Current Sensors to one
SET-3@. The SET-3 output is designed so that the output
voltage will match when one SAO (SE) is used.
Operation is not possible even with a diode inserted.
Operation as shown in figure 2, however, is possible if the
capacity of the CT is sufficient.

Setting Procedure
The operating value will change when single phase is used as in the
figure above. Therefore, the setting must be changed.
Make the setting to approximately 0.77 times the current at which
operation is desired. For example, for operation at 10 A, set the value
to the following:
10 x 0.77 = 7.7 A
In any case, the SAO is adjusted for three-phase use. As a
precautionary measure, therefore, perform confirmation testing using
the actual load.
