Operation
■ Settings
Current Sensor Switch Settings
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.
Setting Operating Time
LED Indicator
The LED indicates that an overcurrent
has occurred and the relay is operating.
Test Button
Pressing the test button momen-
tarily operates the output relay. The
LED indicator, however, does not
light during this operation.

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.

Time Setting Knob
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.
