Setting Methods
●Asymmetry
The asymmetry rate is set using the asymmetry rate knob (ASY).
The setting range is 5% to 22% of the rated input.
To correctly detect asymmetry, set the asymmetry rate knob to a value that is equal to or less than the overvoltage/undervoltage set value. If
you set it to a value that is greater than the overvoltage/undervoltage set value, overvoltage/undervoltage detection will operate first, and
asymmetry alarms will not be output.
If the knob is turned with an input applied to the input terminals, the alarm indicator will flash when the set value equals the input value.
Use this as a guide to make the setting.
The rated input depends on the model and the rotary switch setting.
Example: K8DS-PZ1 with Rotary Switch Set to 200 V
The rated input is 200 VAC, so the setting range is 4 to 44 V.
If you set the setting knob (ASY.) to 10%, the asymmetry operating voltage would be 20 V and an alarm would be output when the
difference between the highest and lowest phase-to-phase voltages exceeds 20 V.
●Overvoltage/Undervoltage
Overvoltage/Undervoltage is set using the overvoltage/undervoltage knob (OV/UV).
The setting range is 2% to 30% of the rated input for overvoltage detection and −2% to −30% of the rated input for an undervoltage detection.
Use this as a guide to make the setting.
The rated input depends on the model and the rotary switch setting.
Example: K8DS-PZ1 with Rotary Switch Set to 200 V
The rated input is 200 VAC, so the setting range is 204 to 260 V for overvoltage detection and 140 to 196 V for undervoltage
detection.
●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 (or drops lower than) the voltage set value, the alarm indicator will start flashing for the set period and then stay lit.

Questions and Answers
Q
Q
Checking Operation
How to Measure the Operating Time
Overvoltage
Change the input value quickly from 70% to 120% of the set
value and measure the time required for the Relay to operate.
Undervoltage
Change the input value quickly from 120% to 70% of the set
value and measure the time required for the Relay to operate.
Operating Time
Adjust the slide resistor so that the voltage applied to the
K8DS terminals is 120% of the set value for overvoltage
detection, 80% of the set value for undervoltage detection, or
equal to or greater than the asymmetry operating value when
the auxiliary relay in connection diagram 2 operates.
Close the switch and use a cycle counter to measure the
operating time.
Overvoltage
Gradually increase the input from 80% of the set value. The
input will equal the operating value when the input exceeds
the set value and the alarm indicator starts flashing.
Operation can be checked because the Relay will operate
after the operating time has passed.
Undervoltage
Gradually decrease the input from 120% of the set value and
check the operation using the same method as for an
overvoltage.

Time Setting of 5 s

Questions and Answers
Q
Q
Load-side Phase Loss
In principle, phase loss cannot be detected on the load side
because the K8DS-PZ measures three-phase voltage to
determine phase loss.
Q
Motor Load Phase Loss during Operation
Motor load phase loss cannot be detected during operation. It
can be used to detect phase loss at startup.
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 has been 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 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. To detect motor load phase loss during operation, use
the undervoltage detection function to detect the motor
terminal voltages at phase loss.
Set the operating time carefully because it will affect the time
from when the phase loss occurs until tripping when this
function is used.

8
Is an overvoltage detected if only one of the three-phase
phase-to-phase voltages exceeds the overvoltage set
value?
The K8DS monitors all three phase voltages. Therefore, an
overvoltage is detected if only one of the phase-to-phase
voltages exceeds the set value. The same is true for
undervoltages.
