●Undervoltage Operation Diagram
Note: 1. The K8DS-PU 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 (on power supply side and load side) is not
detected in the motor load during operation.
Operation Table
*1 L2 and L3 are also used for the power supply. If the voltage becomes very
low, the indicator will turn OFF.
*2 The indicator will flash once per second after an incorrect phase is detected
and once per 0.5 second during the detection time.

Setting Methods
●Undervoltage
Undervoltage is set using the undervoltage knob (UNDER).
The undervoltage can be set to between −30% and 25% 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 set the voltage.
The rated input depends on the model and the rotary switch setting.
Example: K8DS-PU1 with Rotary Switch Set to 200 V
The rated input voltage is 200 VAC and the setting range is 140 to 250 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 (or drops lower than) the voltage set value, the alarm indicator will start flashing for the set period and then stay lit.

Checking Operation
Undervoltage
Gradually reduce the input from 120% of the set value. The
input will equal the operating value when the input goes below
the set value and the alarm indicator starts flashing.
Operation can be checked because the Relay will operate
after the operating time has passed.
How to Measure the Operating Time
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 80% of the set value when the auxiliary
relay in connection diagram 2 operates.
Close the switch and use a cycle counter to measure the
operating time.
Checking the Phase Sequence and Phase Loss
Operation
Phase Sequence
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
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-PU measures three-phase voltage to
determine phase loss.
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.
Characteristic Curve Diagram
Note: For phase loss of phase R. VST, VTR, and VRS indicate the motor
terminal voltage at phase loss.
Is an undervoltage detected if only one of the three-
phase phase-to-phase voltages is less than the
undervoltage set value?
The K8DS monitors all three phase voltages. Therefore, an
undervoltage is detected if only one of the phase-to-phase
voltage is less than the set value.

expenses (including attorney's fees and expenses) related to any claim, inves-
tigation, litigation or proceeding (whether or not Omron is a party) which arises
or is alleged to arise from Buyer's acts or omissions under these Terms or in
any way with respect to the Products. Without limiting the foregoing, Buyer (at
its own expense) shall indemnify and hold harmless Omron and defend or set-
tle any action brought against such Companies to the extent based on a claim
that any Product made to Buyer specifications infringed intellectual property
rights of another party.
16. Property; Confidentiality. Any intellectual property in the Products is the exclu-
sive property of Omron Companies and Buyer shall not attempt to duplicate it
in any way without the written permission of Omron. Notwithstanding any
charges to Buyer for engineering or tooling, all engineering and tooling shall
remain the exclusive property of Omron. All information and materials supplied
by Omron to Buyer relating to the Products are confidential and proprietary,
and Buyer shall limit distribution thereof to its trusted employees and strictly
prevent disclosure to any third party.
17. Export Controls. Buyer shall comply with all applicable laws, regulations and
licenses regarding (i) export of products or information; (iii) sale of products to
“forbidden” or other proscribed persons; and (ii) disclosure to non-citizens of
regulated technology or information.
18. Miscellaneous. (a) Waiver. No failure or delay by Omron in exercising any right
and no course of dealing between Buyer and Omron shall operate as a waiver
of rights by Omron. (b) Assignment. Buyer may not assign its rights hereunder
without Omron's written consent. (c) Law. These Terms are governed by the
law of the jurisdiction of the home office of the Omron company from which
Buyer is purchasing the Products (without regard to conflict of law princi-
ples). (d) Amendment. These Terms constitute the entire agreement between
Buyer and Omron relating to the Products, and no provision may be changed
or waived unless in writing signed by the parties. (e) Severability
. If any provi-
sion hereof is rendered ineffective or invalid, such provision shall not invalidate
any other provision. (f) Setoff. Buyer shall have no right to set off any amounts
against the amount owing in respect of this invoice. (g) Definitions. As used
herein, “including” means “including without limitation”; and “Omron Compa-
nies” (or similar words) mean Omron Corporation and any direct or indirect
subsidiary or affiliate thereof.
Certain Precautions on Specifications and Use
1. Suitability of Use. Omron Companies shall not be responsible for conformity
with any standards, codes or regulations which apply to the combination of the
Product in the Buyer’s application or use of the Product. At Buyer’s request,
Omron will provide applicable third party certification documents identifying
ratings and limitations of use which apply to the Product. This information by
itself is not sufficient for a complete determination of the suitability of the Prod-
uct in combination with the end product, machine, system, or other application
or use. Buyer shall be solely responsible for determining appropriateness of
the particular Product with respect to Buyer’s application, product or system.
Buyer shall take application responsibility in all cases but the following is a
non-exhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical
interference, or conditions or uses not described in this document.
(ii) Use in consumer products or any use in significant quantities.
(iii) Energy control systems, combustion systems, railroad systems, aviation
systems, medical equipment, amusement machines, vehicles, safety equip-
ment, and installations subject to separate industry or government regulations.
(iv) Systems, machines and equipment that could present a risk to life or prop-
erty. Please know and observe all prohibitions of use applicable to this Prod-
uct.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT
ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO
ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROP-
ERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE
OVERALL EQUIPMENT OR SYSTEM.
2. Programmable Products. Omron Companies shall not be responsible for the
user’s programming of a programmable Product, or any consequence thereof.
3. Performance Data. Data presented in Omron Company websites, catalogs
and other materials is provided as a guide for the user in determining suitabil-
ity and does not constitute a warranty. It may represent the result of Omron’s
test conditions, and the user must correlate it to actual application require-
ments. Actual performance is subject to the Omron’s Warranty and Limitations
of Liability.
4. Change in Specifications. Product specifications and accessories may be
changed at any time based on improvements and other reasons. It is our prac-
tice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifica-
tions of the Product may be changed without any notice. When in doubt, spe-
cial part numbers may be assigned to fix or establish key specifications for
your application. Please consult with your Omron’s representative at any time
to confirm actual specifications of purchased Product.
5. Errors and Omissions. Information presented by Omron Companies has been
checked and is believed to be accurate; however, no responsibility is assumed
for clerical, typographical or proofreading errors or omissions.
