Features
Monitor Power and Earth Leakage with
Just One Unit
KE1-PGR1C-FLK
You can monitor power to save energy and monitor earth leakage for
electrical equipment all with just one Unit. You can flexibly add CT or
ZCT Units to measure multiple circuits as required.
There is an increasing need to detect problems in advance to protect
against extensive losses from production line and production facility
stoppage due to earth leakage faults.
There is also a need to introduce power monitoring to save energy.
There is a need to measure both earth leakage and power from a
switch panel or distribution panel with only one infrastructure
investment.
The KE1 is the first product line in the world to respond to the need for
smart multi-circuit measurements for power monitoring and earth
leakage monitoring.
Power Fluctuation Logging
KE1-PVS1C-FLK and KE1-VSU1B-FLK
Momentary voltage sags are a serious problem for precision
equipment, such as semiconductor and liquid crystal manufacturing
facilities. The power grid in emerging countries is often unstable,
resulting in problems such as facility stoppage and failure due to
momentary voltage sags. The KE1 detects momentary voltage sags
and outputs an alarm in 25 ms. It also logs voltage fluctuations in the
Unit’s internal memory for 1,000 ms before and after a voltage sag so
that you can check for the impact of the voltage sag on quality. You
can also use it for SEMI-F47 traceability information to enable
effective facility maintenance.

System Configuration
The KE1 is built by combining four types of Units: Measurement Masters, Function Slaves, CT Expansion Slaves, and Communications Slaves.
The Measurement Masters and Function Slaves can also be used for standalone operation.
You can connect a Measurement Master and Slaves to save both wiring work and space.
Maximum Configuration
You can connect up to four Function Slaves and CT Expansion Slaves and one Communications Slave (i.e., a total of five Slaves) to one
Measurement Master. You cannot connect only Function Slaves together.

Turn OFF DIP switch pin 1 to set simple assignment.
The setting is read only once when the power supply is turned ON.
Any changes while power is ON are ignored. To change the setting,
turn OFF the power supply, set the switch, and then turn ON the
power supply.
• Node Address Setting
Set the address of the Unit as a slave on the DeviceNet network to a
decimal number between 00 and 63. (Do not set addresses 64 to 99.)
Set the 1s digit on the bottom rotary switch (×100) and set the 10s digit
on the top rotary switch (×101). You can set any node address that is
within the specified range as long as the same address is not set for
another node (Master, Slave, or Configurator) on the same network.

Special CT Connections
• Separate RS-485 cables and power lines to prevent the influence
of noise.
• Use a twisted-pair cable of AWG24 (cross-sectional area: 0.205
mm2) to AWG14 (cross-sectional area: 2.081 mm2). (The stripping
length is 5 to 6 mm)
• Do not ground the RS-485 communications cable. Failure may
occur.
• Connect terminating resistance (120 Ω (1/2 W)) between the
positive and negative RS-485 pins on the host device and the last
device (normally a KE1). When connecting terminating resistance
to the host device, check the manual provided with the host device.

circuit. Two CTs are required to measure a single-phase, threewire circuit or three-phase, three-wire circuit. Three CTs are
required to measure a three-phase, four-wire circuit.
• Make sure that the ratings of the Special CTs and the Special CT
setting in the KE1 are the same.
• Check the directions of the power supply (K) and load (L) before
making the connections. Correct measurements will not be
possible if they are connected in the wrong directions.
• Release the locking hook and clamp the CT on the line. Do this for
each phase. Then, press the hook firmly until you hear it lock into
place.
• Make sure that the terminal cover on the secondary side of the CT
is closed securely.
• Do not ground the
Load (L)
Special CTs.
Failure may occur.
• The Special CTs have
polarity.

• Use the Special CT Cable (KM20-CTFCB3: 3 m) to connect the
Special CT. Connect the Special CT to the end with the shrinking
tube.
• Electric shock may occasionally occur.
Always use a sheathed cable with basic insulation of 600 V or
higher for the primary cable clamped by the CT.
If you clamp onto a busbar or other conductive item, cover it with
insulation or otherwise provide at least the required basic
insulation.

Power Measurement Functions
Earth Leakage Monitoring
KE1-PGR1C-FLK/-PVS1C-FLK/-CTD8E
The active power, reactive power, power factor, and total power
consumption are measured on the circuits to measure.
By combining the Units with KE1-CTD8E CT Expansion Units, you
can measure up to 35 circuits.
(The number of circuits that can be measured depends on the wiring
methods of the circuits that are measured.)
Just set the detection values in advance to detect upper and lower
limits and save alarms in an alarm history in the Unit.
Also, the KE1-PGR1C-FLK (Power/Earth Leakage Monitor Unit) and
KE1-PVS1C-FLK (Power/Momentary Voltage Sag Monitor Unit)
Measurement Masters can log various types of measurement data.
(The number of days for which data can be logged depends on the
logging period.)
The measured power values and alarm records can be sent via
communications to a computer or other host system.
KE1-PGR1C-FLK/-ZCT8E
Earth leakage from insulation deterioration of the circuits to monitor
can be detected.
By combining with KE1-ZCT8E ZCT Expansion Units, you can
monitor earth leakage on up to 33 circuits.
If the detected earth leakage current reaches or exceeds the preset
value, the detection time and alarm type are stored in the alarm
history.
Alarm settings can also be made to output alarms.
The measured earth leakage currents and alarm records can be sent
via communications to a computer or other host system.
Note: You can connect a computer on which OMRON’s EasyKM
Manager is installed to constantly monitor earth leakage and
earth leakage trends.
Note: Do not use this function for the secondary side of an inverter.
Note: You can connect a computer on which OMRON’s EasyKM
Manager is installed to constantly monitor power and calculate
the total demand.

KE1
Momentary Voltage Sag Detection
KE1-PVS1C-FLK/-VSU1B-FLK
If a voltage sag that conforms to SEMI-F47 continues for the specified
time or longer, it is detected as a momentary voltage sag, the actual
voltages before and after it are recorded in memory, and an alarm is
recorded in the alarm history.
Alarm settings can also be made to output alarms.
If you connect a UPS or other backup power supply that is not
affected by momentary voltage sags, you can output an alarm for up
to 1 second after the momentary voltage sag occurs.
Example: If the momentary voltage sag detection function is set to Vrs, the momentary voltage sag detection voltage is set to 170 V, and the
momentary voltage sag time is set to 0.02 seconds, a momentary voltage sag is detected when the voltage between the R and S lines
of the three-phase, three-wire system if the voltage drops below 170 V for the momentary voltage sag detection time or longer. The
output turns ON within 5 ms of when the momentary voltage sag is detected.

Precautions for Safe Use
The following items must be observed to prevent failure to operate
and malfunctions of the Units and to prevent adverse effects on
performance and functions of the Units.
1. Do not use, store, or transport the Units in the following locations.
• Locations that are greatly affected by vibration or shock
• Unstable locations
• Locations where the specified range of temperature or humidity
would be exceeded
• Locations that are subject to rapid changes in temperature or
humidity where condensation or icing may occur
• Locations that are subject to direct sunlight.
• Outdoors or locations that are subject to wind or rain
• Locations that are affected by static electricity or noise
• Locations that are subject to water, oil or saltwater.
• Locations that are subject to corrosive gas (particularly sulfide or
ammonia gas)
• Locations that are subject to dust or iron powder
• Locations that are affected by electric or magnetic fields
2. When you install DIN tracks, make sure that the screws are
tightened securely. Mount the Units securely to the DIN Track. If
any Units are loose, vibration or shock can cause the DIN Track,
Units, or wires to become disconnected.
3. Use DIN Tracks with a width of 35 mm (OMRON PFP-50N/-100N).
4. Use crimp terminals that are suitable for M3.5 screws to wire the
Units.
5. Check the specifications and wiring to be sure there are no
mistakes before you turn ON the power supply.
6. Read and understand the Unit manuals before attempting to
install, use, or maintain the Units. Electric shock, injury, accidents,
failure, or malfunction may occur.
7. Install and suitably label a switch or circuit breaker that complies
with relevant requirements of IEC 60947-1 and IEC 60947-3 so
that the operator can immediately turn OFF the power supply.
8. Understand the manuals when you set the Units.
9. Install the Units separated as far as possible from devices with
strong high-frequency noise or devices that generate surge.
10.Touch grounded metal to discharge any static electricity before
touching the Units.
11.To prevent inductive noise, wire the lines connected to the Units
separately from power lines carrying high voltages or currents. Do
not wire in parallel with or on the same cable as power lines. Other
measures for reducing noise include running lines in separate
ducts and using shields.
12.Do not install the Units near sources of heat, such as devices with
coils or windings.
13.Do not allow metal objects, conductors, or cuttings from
39
KE1
installation work to enter the Units.
14.Do not use solvents, such as paint thinners, to clean the Units. Use
commercially available alcohol instead.
15.Use a power supply voltage and wires with suitable specifications
for the control power supply and the power supply for inputs and
other parts of the system. Failure, burning, or electrical shock may
result.
16.If you install a Unit on a wall, install it so that the screws are not
loose. If any Units are loose, vibration or shock may cause the Unit
or wires to become disconnected.
17.If you use more than one Unit together, slide them together until
the horizontal connection hooks audibly lock in place.
18.If you mount the Units on DIN Track, slide them until the DIN hooks
audibly lock in place.
19.Use only the Special CTs, Special ZCTs, and Special CT Cable
specified by OMRON.

20.Do not use the Units for measurement on the secondary side of an
inverter.
21.Do not block the ventilation holes in or the areas around the Units
to ensure proper dissipation of heat.
22.Check all terminal numbers before wiring. Do not connect anything
to unused terminals.
23.The Units are a Class A products (for use in industrial
environments). In residential environment areas, they may cause
radio interference. If they cause radio interference, the user may
be required to take adequate measures to reduce interference.
24.Use the Special CTs and Special ZCTs at a low voltage of 600 V
or less.
Installation Precautions
Maintaining Product Life
Use the KE1 within the following temperature and humidity ranges.
Temperature: −10 to 55°C (with no icing or condensation)
Humidity: 25% to 85%
Do not let the ambient temperature around the Units exceed 55°C.
(This is not the ambient temperature around the panel.)
Some of the electronic components used in the Units have limited
service lives. The life of these components depends on the ambient
temperature. The service lives will be shorter at higher temperatures
and longer at lower temperatures. The life of the Units can thus be
extended by lowering the internal temperature. If more than one KE1
Unit is mounted side by side or top to bottom, you must consider using
forced cooling, such as fans that circulate air around the Units.
Noise Countermeasures
To prevent inductive noise, wire the lines connected to the terminal
block on the Units separately from power lines carrying high voltages
or currents. Do not wire in parallel with or on the same cable as power
lines. Other measures for reducing noise include running lines in
separate ducts and using shields.
Attach surge absorbers or noise filters to nearby equipment that
generates noise (particularly equipment with a high inductance
component, such as motors, transformers, or magnetic coils).
Install the Units as far as possible away from devices with strong highfrequency noise (such a high-frequency welders or sewing machines)
or devices that generate surge.
40
Precautions for Correct Use
1. Make sure that all parameters are set suitably for the monitor
targets.
2. Do not pull on the cables.
3. When discarding the Units, dispose of them according to all local
laws and ordinances as they apply. Dispose of the Units as
industrial waste.
4. When using the Units in an Overvoltage Category III environment,
externally install varistors between the power supply and voltage
measurement inputs to the Units.
