Omron K6EL, K6EL-500 Manual

Omron K6EL, K6EL-500 Manual

Omron K6EL-500 is a high-speed, compact ground fault relay designed for use in low-voltage circuits. It features a selectable operating time of less than 0.1 seconds and is engineered for high reliability, even when working with inverter loads. The K6EL-500 offers flexibility with its switchable sensed current, allowing you to adjust sensitivity based on your specific application requirements. For remote monitoring, the automatic-reset models provide continuous fault detection and alert you to potential issues. The K6EL-500 is compatible with a range of through-type ZCTs (Zero-phase Current Transformers), simplifying installation and ensuring seamless integration into your electrical system.

Ground Fault Relay
K6EL
Economical, Compact, High-performance,
DIN 48 u 48-mm Ground Fault Relay for Low
Voltages
• Performs continuous monitoring and detection of ground faults
in low-voltage circuits due to the deterioration of insulation in
electrical devices.
• Higher reliability ensured with improved resistance to high-frequency noise when used for inverter loads.
• Remote monitoring of cubicles is possible with automatic-reset
models.
• Ground Fault Relays and through-type ZCTs (zero-phase current transformers) are mutually compatible.
• The through-type ZCTs are equipped with test terminals, allowing operation tests for Ground Fault Relays to be performed with
ease.
• Series now includes K6EL-R50, which operates at
50 mA r10%.

Select the resistance R shown in the test circuit diagram according to
the K6EL’s rated sensed current. Change the current using the slidac
and ascertain the K6EL’s operating value each time by reading the
ammeter.
For example, R could take the values shown below:
30 mA: 3.3 k:, 6 W
100 mA: 1 k:, 20 W
Safety Precautions
■ Correct Use
Switching the Operating Time
Installation and Wiring
• Do not, under any circumstances, connect the ZCT’s output terminals k and l to ground. Doing so may result in damage to the
Relay’s internal circuits.
• Pass the primary conductor through the ZCT once.
• The Relay detects ground faults in internal wiring of devices due to
insulation deterioration and so install the ZCT as close to the power
supply side as possible.
1. With the K6EL-A100, A200, and A500, the operating time can be
switched using a flat-bladed screwdriver.
2. The operating time for the K6EL-30, 100, 200, 500, R50, and
R500 is fixed and hence cannot be switched.
ZCT Installation
• Install the ZCT at an outdoor cable inlet or on a ground bus bar at a
location allowing easy inspection.
• When installing on the electrical path, use a ZCT with a value
greater than the electrical path’s rated current.
• If the secondary lines run in parallel to a circuit carrying a large current, either separate the lines as far as possible or use a shield line.
Run the secondary lines
close to each other.

Testing

K6EL
Primary conductor
Separate by 20 cm min.
Circuit carrying large current
• When installing a separate-type ZCT with current flowing along the
primary conductors, short the secondary terminals using clips or
some other method.
Switching the Sensed Current
• If the ground fault indicator (red) lights when the Relay’s test button
is pressed, it means that the internal circuits are operating normally.
• To make an overall test, run a simulated ground fault current.
Resetting
• Once manual-reset models operate, they continue to operate until
they are reset. Reset them either by pressing the reset button
(black) or by turning the control power supply OFF and ON again.
• Automatic-reset models reset automatically when the ground fault
is cleared (i.e., the current drops below the sensed current).
1. With the K6EL-@100, 200, 500, R50, and R500, the sensed current can be switched using a flat-bladed screwdriver.
2. The sensed current for the K6EL-30 is fixed and hence cannot be
switched.

K6EL
Q&A
Q: How does the K6EL operate when used for inverter loads (e.g., inverter motors and inverter air conditioners)?
A: The influence of high-frequency noise generated by the inverter has been reduced by combining a special ground
fault relay IC and a capacitor for cutting out high-frequencies. The possibility of malfunctions due to the influence
of the inverter is much less than with the existing ESA Ground Fault Relay.

Q: What connection method should be used for ungrounded electrical paths?
A: With ungrounded electrical paths, connect the capacitor or resistor for detection in the way shown in the diagram.
The table shows the formulas for calculating the resistance or capacitance as well as the formulas for calculating
ground currents for complete ground faults. (Depending on the location, the allowable ground fault current may be
restricted. In this case, use values of R and C that do not exceed the restrictions.)

The following are some examples of applications for which particular attention must be given. This is not intended to be an exhaustive list of all possible
uses of the products, nor is it intended to imply that the uses listed may be suitable for the products:
• Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this catalog.
• Nuclear energy control systems, combustion systems, railroad systems, aviation systems, medical equipment, amusement machines, vehicles, safety
equipment, and installations subject to separate industry or government regulations.
• Systems, machines, and equipment that could present a risk to life or property.
Please know and observe all prohibitions of use applicable to the products.
NEVER USE THE PRODUCTS FOR AN APPLICATION INVOLVING SERIOUS RISK TO LIFE OR PROPERTY WITHOUT ENSURING THAT THE
SYSTEM AS A WHOLE HAS BEEN DESIGNED TO ADDRESS THE RISKS, AND THAT THE OMRON PRODUCT IS PROPERLY RATED AND
INSTALLED FOR THE INTENDED USE WITHIN THE OVERALL EQUIPMENT OR SYSTEM.
Disclaimers
CHANGE IN SPECIFICATIONS
Product specifications and accessories may be changed at any time based on improvements and other reasons.
It is our practice to change model numbers when published ratings or features are changed, or when significant construction changes are made.
However, some specifications of the product may be changed without any notice. When in doubt, special model numbers may be assigned to fix
or establish key specifications for your application on your request. Please consult with your OMRON representative at any time to confirm actual
specifications of purchased product.
DIMENSIONS AND WEIGHTS
Dimensions and weights are nominal and are not to be used for manufacturing purposes, even when tolerances are shown.
ERRORS AND OMISSIONS
The information in this catalog has been carefully checked and is believed to be accurate; however, no responsibility is assumed for clerical,
typographical, or proofreading errors, or omissions.
PERFORMANCE DATA
Performance data given in this catalog is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent
the result of OMRON’s test conditions, and the users must correlate it to actual application requirements. Actual performance is subject to the OMRON
Warranty and Limitations of Liability.

Frequently Answers and Questions

What are the different operating times available for the K6EL-500?
The K6EL-500 offers a fixed operating time of less than 0.1 seconds. This ensures quick and efficient detection of ground faults.
Can the K6EL-500 be used with inverter loads?
Yes, the K6EL-500 is designed to work reliably with inverter loads, such as inverter motors and inverter air conditioners. It features improved resistance to high-frequency noise.
How do you reset a manually-reset K6EL-500 after a ground fault?
To reset a manually-reset K6EL-500, press the reset button (black) or turn the control power supply off and on again.
