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.

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.

Checking Operation
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.
Asymmetry
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 (%)
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.
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-PZ 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 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.

d. Delivery and shipping dates are estimates only; and
e. Omron will package Products as it deems proper for protection against nor-
mal handling and extra charges apply to special conditions.
12. Claims. Any claim by Buyer against Omron for shortage or damage to the
Products occurring before delivery to the carrier must be presented in writing
to Omron within 30 days of receipt of shipment and include the original trans-
portation bill signed by the carrier noting that the carrier received the Products
from Omron in the condition claimed.
13. Warranties. (a) Exclusive Warranty. Omron’s exclusive warranty is that the
Products will be free from defects in materials and workmanship for a period of
twelve months from the date of sale by Omron (or such other period expressed
in writing by Omron). Omron disclaims all other warranties, express or implied.
(b) Limitations. OMRON MAKES NO WARRANTY OR REPRESENTATION,
EXPRESS OR IMPLIED, ABOUT NON-INFRINGEMENT, MERCHANTABIL-
ITY OR FITNESS FOR A PARTICULAR PURPOSE OF THE PRODUCTS.

INTENDED USE. Omron further disclaims all warranties and responsibility of
any type for claims or expenses based on infringement by the Products or oth-
erwise of any intellectual property right. (c) Buyer Remedy. Omron’s sole obli-
gation hereunder shall be, at Omron’s election, to (i) replace (in the form
originally shipped with Buyer responsible for labor charges for removal or
replacement thereof) the non-complying Product, (ii) repair the non-complying
Product, or (iii) repay or credit Buyer an amount equal to the purchase price of
the non-complying Product; provided that in no event shall Omron be responsi-
ble for warranty, repair, indemnity or any other claims or expenses regarding
the Products unless Omron’s analysis confirms that the Products were prop-
erly handled, stored, installed and maintained and not subject to contamina-
tion, abuse, misuse or inappropriate modification. Return of any Products by
Buyer must be approved in writing by Omron before shipment. Omron Compa-
nies shall not be liable for the suitability or unsuitability or the results from the
use of Products in combination with any electrical or electronic components,
circuits, system assemblies or any other materials or substances or environ-
ments. Any advice, recommendations or information given orally or in writing,
are not to be construed as an amendment or addition to the above warranty.

lished information.
14. Limitation on Liability; Etc. OMRON COMPANIES SHALL NOT BE LIABLE
FOR SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES,
LOSS OF PROFITS OR PRODUCTION OR COMMERCIAL LOSS IN ANY
WAY CONNECTED WITH THE PRODUCTS, WHETHER SUCH CLAIM IS
BASED IN CONTRACT, WARRANTY, NEGLIGENCE OR STRICT LIABILITY.
Further, in no event shall liability of Omron Companies exceed the individual
price of the Product on which liability is asserted.
15. Indemnities. Buyer shall indemnify and hold harmless Omron Companies and
their employees from and against all liabilities, losses, claims, costs and
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.
