Note:
1. The K8DS-PA† output contacts are normally operative.
2. The power ON lock prevents unnecessary alarms from being generated during the unstable
period when the power is first turned ON. There is no contact output during timer operation.
3. Phase loss is detected by a drop in the L1, L2, or L3 voltage. A phase loss is detected when
any of the phase-to-phase voltages goes below 60% of the rated input.
4. L2 and L3 are also used for the power supply. If the voltage becomes very low, the Relay
will not operate.
5. Phase loss is not detected in the motor load during operation.
6. Phase loss cannot be detected on the load side because detection is based on the voltage.
Calculation Formula for Asymmetry Operating Value
Asymmetry operating condition = (Highest voltage − Lowest voltage) > Asymmetry
operating value
Asymmetry operating value = Rated input voltage (V) × Asymmetry set value (%)
Note: The rated input voltage is set with a rotary switch.

Setting Methods
●Asymmetry
The asymmetry rate is set using the asymmetry rate knob (ASY.)
The setting range is 2% to 22% of the rated input.
Turn the knob while there is an input to the input terminals until the alarm indicator flashes (when the set value and the input have reached the
same level.)
Use this as a guide to make the setting.
The rated input depends on the model and the rotary switch setting.
Example: K8DS-PA1 with Rotary Switch Set to 200 V
The rated input is 200 VAC, so the setting range is 4 to 44 V.
If the setting (ASY. knob) is at 10%, the asymmetry operation voltage is 20 V and an alarm will be output if the difference between
the minimum and maximum phases for two of the three phases exceeds 20 V.
●Operating Time
The operating time is set using the operating time knob (T).
The operating time can be set to between 0.1 and 30 s.
Turn the knob while there is an input to the input terminals until the alarm indicator flashes (when the set value and the input have reached the
same level.)
Use this as a guide to set the operating time.
If the input exceeds the asymmetry set value, the alarm indicator will start flashing for the set period and then stay lit.

Questions and Answers
Q
Q
Checking Operation
With the rated input voltage applied, gradually change one of
the phase-to-phase voltages. The Relay will operate when
the difference between the highest and lowest voltage
phases reaches or exceeds the asymmetry operating value.
Asymmetry operating value = Rated input voltage ×
Asymmetry set value (%)
Phase Sequence Operation
Switch the wiring, as shown by the dotted lines in connection
diagram 1, to reverse the phase sequence and check that the
K8DS operates.
Phase Loss Operation
Create a phase loss for any input phase and check that the
K8DS operates.

Load-side Phase Loss
In principle, phase loss cannot be detected on the load side
because the K8DS-PA† measures three-phase voltage to
determine phase loss.

Operation
How to Measure the Operating Time
Operating Time
Adjust the slide resistor so that the voltage difference applied
to the K8DS terminals is equal to or greater than the
asymmetry operating value when the auxiliary relay operates,
as shown in connection diagram 2.
Close the switch and use a cycle counter to measure the
operating time.
Motor Load Phase Loss during Operation
Phase loss cannot be detected for motor loads during
operation. Use the asymmetry detection function.
Normally, three-phase motors will continue to rotate even if
one phase is open. The three-phase voltage will be induced
at the motor terminals. The diagram shows voltage induction
at the motor terminals when phase R is lost with a load
applied to a three-phase motor. The horizontal axis shows the
motor load as a percentage of the rated load, and the vertical
axis shows voltage as a percentage of the rated voltage. The
lines in the graph show the voltage induced at the motor
terminals for each load when phase loss occurs during
operation. As the graph shows, phase loss cannot be
detected because the motor terminal voltage does not drop
very much even if a phase is lost when the load on the motor
is light. Use the asymmetry detection function to detect
asymmetry in the motor terminal voltages.
Set the operating time carefully because it will affect the time
from when the phase loss occurs until tripping when this
function is used.
