FG terminal must be grounded according to the D-type ground (Type 3) dedicated for sequencer.
Failure to do so may result in electric shock or malfunction.
When using this product, make sure to use it in combination with current sensor (EMU-CT***,
EMU-CT***-A or EMU2-CT5-4W) and Voltage transform module (QE8WH4VT). Please not to exceed
the ratings of this product for input of current sensor. For further details, please refer to current sensor
manual to maintain the functionality and the accuracy of this product. The available range of the voltage
transform module is from 63.5/110 to 277/480V AC. When used in a circuit more than 227/480V AC,
voltage transformer is required.
Current sensor (EMU-CT***, EMU-CT***-A (Excluding EMU-CT5-A)) is used only for low voltage circuit.
It cannot be used with a high voltage circuit. Also, EMU2-CT5-4W and EMU-CT5-A should be used with
the secondary side (5 A) of transformer transfixed. If it is connected with a high-voltage circuit by
mistake, it may cause a burnout of the device and a fire. It is critically dangerous. For the Allowable
maximum voltage, refer to Appendix 2 “Optional devices”.
Current sensor has a polarity (directionality). Be careful about it when installing the module.
Do not open the secondary side of current sensor.
Take care not entering any foreign objects such as chips and wire pieces into the module. It may cause
a fire, failure or a malfunction.
In order to prevent the module from incoming foreign objects such as wire pieces during wiring work, a
foreign-object preventive label is placed on the module. While a wiring work is performed, keep the label
on the module. Before operating the system, peel off the label for heat release. If the foreign-object
preventive label is not peeled and the system is in use, residual heat inside the module may reduce the
product life.
The wires to be connected to the module shall be put in a duct or fixed together by clamp. If not, the
loosing and unstable wire or careless stretching results in poor contact of electric wires. That may cause
a breakage of the module or wire or a malfunction.
After wiring, confirm whether there is a wiring forgetting or a faulty wiring. They may cause a device
malfunction, a fire, or an electric shock.
When removing the wires connected to the module, do not pull wires as holding on their electric wire
portions. Push the buttons on the terminal, and then remove the wire.

(4) Restrictions for measuring data
- Measurement cannot be performed immediately after the power loading to the sequencer
system (Module ready signal is under the OFF condition).
After checking that Module ready (Xn0) is ON, obtain measuring data.
- Measurement cannot be performed immediately after operating conditions are set up to the
module. After checking that Operating condition setting completion flag (Xn9) becomes ON,
obtain measuring data.
- Behaviors during operation are as follows:
Measuring item
Behavior of the module
Current
When the input current is less than 0.4% of the rating current, it
becomes 0A.
Current demand
Current demand is obtained by current moving average.
Therefore, even if current is 0A, current demand may not be 0A.
When the input voltage (L-N) is less than 55V, it becomes 0V.
If there is no input at voltage V1N, all measurement cannot be
done.
When the input voltage (L-L) is less than 95V, it becomes 0V.
When current is 0A (at all phases are 0A) or when voltage is 0V
(all phases are 0V), it becomes 0kW.
Voltage (L-N)
Voltage (L-L)
Electric power,
Reactive power,
Apparent power
Electric power demand
Electric energy

Frequency
Electric power demand is obtained by electric power moving
average. Therefore, even if electric power is 0kW, electric power
demand may not be 0kW.
The electric energy is measured with a load that is about 0.4% or
more of all load power. Even if the indicated value is “0”,
measurement value will increase.
When current is 0A (at all phases are 0A) or when voltage is 0V
(all phases are 0V), it becomes 100%.
Voltage condition
When the input voltage (L-N) is less than 55V, it becomes 0Hz.
Frequency condition
When it is less than 44.5Hz, it is fixed to 44.5Hz.

3) How to reset Alarm flag during self-retention (in the case the alarm reset method =
“self-retention” only)
Refer to the procedure described in (2) 1).
(4) Precautions during the alarm monitoring
1) When current demand time and electric power demand time are set to anytime except 0
second, current demand and electric power demand become lower than the actual values
(closer to 0) immediately after the power source ON and the CPU reset. When current
demand and electric power demand are being monitored for their lower limit, the alarm
occurrence flag may turn ON. Thus, to avoid this from happening, follow the procedure
below.
(a) Set the alarm monitoring target to “no monitoring” immediately after the power source ON
and the CPU reset.
(b) After passing for a 3-times longer period than the demand time, set the alarm monitoring
target again, and start the alarm monitoring.

time (Un\G15), this signal (Xn9) turns ON.
(b) Operations after this signal (Xn9) is turned ON vary depending on the setting of CH1
alarm 1 reset method (Un\G14).
[When CH1 alarm 1 reset method (Un\G14) is "0: self-retention"]
Even if the measured value of CH1 alarm 1 monitoring target goes below the upper limit (or
if it exceeds the lower limit in the case of lower limit alarm), this signal (Xn9) remains ON.
When CH1 alarm 1 reset request (Yn9) is turned ON, this signal (Xn9) turns OFF.
[When CH1 alarm 1 reset method (Un\G14) is "1: auto reset"]
If the measured value of CH1 alarm 1 monitoring target goes below the upper limit (or it
exceeds the lower limit in the case of lower limit alarm), this signal (Xn9) turns OFF.
(c) When the measured value of the alarm 1 monitoring target is set to "not monitoring", this
signal (Xn9) always turns OFF.
*For the actual behavior of alarm monitoring, refer to Section 4.2.4.

6.2.12 Output period of data acquisition clock (Un\G60, 61)
Set the output period of Data acquisition clock (Xn1). This setting is common to all channels.
・Data acquisition clock (Regular operating mode)
(1) Setting procedure
(a) Set output period of data acquisition clock (Un\G60, 61) in the buffer memory.
- Configurable range: 0 to 86400000 (ms)
*When the output period of data acquisition clock is set to 0, Data acquisition clock (Xn1) is
always OFF.
(b) Because the data update interval is 500 ms, Data acquisition clock (Xn1) runs every 500 ms.
Note that the output period of data acquisition clock is not a multiple of 500 ms, Data acquisition
clock turns ON at the time of the first data update after the elapse of the output period of data
acquisition clock.
<Example> When the output period of data acquisition clock is 1600 ms:
Measurement data update count = 1600 ms/500 ms = quotient 3 + remainder 100
ms.
Thus, the input device (Xn1) turns ON once in every four times the measurement
data is updated.
As a result, it is same as the case where the output period of data acquisition clock is
2000 ms.
(c) Turn Operating condition setting request (Yn2) from OFF to ON to enable the setting.
(2) Default value
It is set to 0 (ms).
・Data acquisition clock (Current measuring mode)
(a) Set output period of data acquisition clock (Un\G4000, 4001) in the buffer memory.
- Configurable range: 0 to 86400000 (ms)
*When the output period of data acquisition clock is set to 0, Data acquisition clock (Xn1) is
always OFF.
(b) Because the data update interval is 100 ms, Data acquisition clock (Xn1) runs every 100 ms.
Note that the output period of data acquisition clock is not a multiple of 100 ms, Data acquisition
clock turns ON at the time of the first data update after the elapse of the output period of data
acquisition clock.
<Example> When the output period of data acquisition clock is 250 ms:
Measurement data update count = 250 ms/100 ms = quotient 2 + remainder 50 ms
Thus, the input device (Xn1) turns ON once in every three times the measurement
data is updated.
As a result, it is same as the case where the output period of data acquisition clock is
300 ms.
(c) Turn Operating condition setting request (Yn2) from OFF to ON to enable the setting.
(2) Default value
It is set to 0 (ms).

2) Connect the voltage transform module to voltage transformer secondary side.
• In any case, circuit voltage can’t directly connect to voltage input terminal of QE83WH4W. Please
connect to voltage output terminal of voltage transform module (QE8WH4VT).
• If used at a circuit higher than 277/480V AC, make sure use a voltage transformer.
• The transformer which has primary voltage of VT less than 6600V and secondary voltage of VT not
more than 220V can be used. Please connect the transformer secondary voltage to P1, P2, P3, and P0
terminals of QE8WH4VT. Make sure that terminal symbols are correct.
• In order to perform maintenance work such as changing the wire layout and replacing equipment, we
recommend that you connect protective device (breaker) for the voltage input circuit of the voltage
transform module (P1, P2, P3, and P0 terminals).

Q&A
10.3.1 General
To what degree is the module durable against overvoltage and overcurrent? Is external
Q
protective circuit required?
Momentary* : Up to 2 times as high as rated voltage and 20 times as high as rated current.
Continuous : Up to 1.1 times as high as rated voltage and rated current.
A
* Momentary means: Energizing 9 times for 0.5 seconds at 1-minute intervals, and then 1 time
for 5 seconds.
External protective circuit is not required.
Q
Can the module be used as an electric energy meter?
A
This module can be used to measure the electric energy and to manage the use of electric
energy.
However, it cannot be used for deal and proof of electric energy measurement stipulated in the
measurement law.
Q
Are errors in wiring verifiable easily?
A
They are verifiable by the illuminating condition of “MEA.,” “1,” “2,” and “3” LEDs on the front of
the module.
Refer to Section 9.2.3 for details.
Q
Is it OK to open the secondary terminals of the current sensor?
A
The secondary side of the models EMU2-CT5-4W, EMU-CT50, EMU-CT100, EMU-CT250,
EMU-CT5-A, EMU-CT50-A, EMU-CT100-A, EMU-CT250-A, EMU-CT400-A, and EMU-CT600-A
is equipped with the protective circuit against opening of secondary terminals. Opening them
during the wiring work causes no problems. However, for safety, please do not continuously
energize the module with the terminals open.
The secondary side of the models EMU-CT400 and EMU-CT600 is equipped with the protective
circuit against opening of secondary terminals. However, during the wiring work, be sure to turn
the secondary side short-circuit switch to short. After completion of work, be sure to turn the
secondary short-circuit switch to open. Note that failing to turn the switch open results in an
inaccurate measurement.
Q
Is measurement of inverter circuit possible?
A
Measuring the secondary side of the inverter is impossible due to the large fluctuation of
frequency.
Make measurement on the primary side of the inverter. However, since a current waveform on
the primary side of the inverter has a distortion containing the harmonic components, a slight
error occurs.

10 Troubleshooting
Q
A
QE83WH4W
If a load such as welding equipment exists, a current flows only for a short period (e.g.
2-cycle waveform of commercial frequency (50 Hz: 40 ms, 60 Hz: 33 ms)). Is accurate
measurement possible?
This module makes measurement with a sampling period of 4340 Hz (for both 50 Hz and
60 Hz). However, measuring part of buffer memory data (Un¥G100 to Un¥G2999) is updated
every 500 ms. The electrical amount such as current, voltage, electric power, power factor, and
frequency is measured in a cycle of 500 ms period.
It is impossible to measure the instantaneous short–term amount of electricity. The amount of
electricity and reactive power amount are measured separately from the momentary data
described above, using a sampling period of 4340 Hz continuously without intermittence.
Therefore, measuring the load for a short period is possible.
Q
Obtained values may be different from other measuring instruments. Why is it so?
A
There are various possible causes. Check the following first, please:
[1] Check for wiring errors (polarity of current sensors, connections of current circuits, and
connections of voltage circuits, in particular).
[2] On the split-type current sensor, check for the poor engagement or separation of fitting
surfaces.
[3] On the split-type current sensor, check for pinching of foreign object between fitting surfaces.
[4] Check that the measuring instrument used for comparison indicates a correct RMS value.
[5] If the measuring instrument used for comparison measures an average value instead of rms
value, distortion in the current of the circuit to be measured causes a significant difference of
values. This module measures an rms value.
[6] Check for the short-circuit on the secondary side of the current transformer (CT).
[7] Current sensor connectable to the module is the dedicated current sensor only. Check that
the proper current sensor is connected or not.
10.3.2 Q&A about Specifications
Q
What accuracy does “measuring accuracy” mean?
A
In terms of the amount of electricity, it means a range of tolerances in reading values. For
example, when the reading value is “10 kWh,” a tolerance is ±0.2 kWh.
In terms of measuring elements other than the amount of electricity, it means tolerance for the
rated input. For a current, when a rated current is set to 250 A, ±1% of 250 A is a tolerance.
Q
Is accuracy of a current sensor and the voltage transform module included?
A
Accuracy of a current sensor and the voltage transform module are not included in accuracy of
the module.
A maximum value of tolerance is obtained by summing tolerance of the module and that of a
current sensor and the voltage transform module.
Q
To what degree an area of microcurrent is measured?
A
A current value is measured from the area exceeding 0.4% of the rated current. In an area
below 0.4%, measurement result is indicated as “0” (zero).
However, in that case, still, the amount of electricity is being measured. Even if the indicated
value is “0,” measurement value will increase in continuing measurement for a long time.
The amount of electricity is measured with a load that is about 0.4% or more of all load power.

10.3.3 Q&A about Installing
Q
What is wire diameter that allows installing a current sensor?
A
The nominal cross-sectional areas of the conductor of 600-V vinyl coated wires that can
penetrate (values for reference), refer to 8.5.3.1.
The above shows the standard nominal cross-sectional areas. Due to the outer difference of
finished vinyl insulation and deformation (bending) depending on manufacturers, a wire may
not penetrate.
Make verification on site.
Q
What are the points when installing a current sensor?
A
Models EMU2-CT5-4W, EMU-CT*** and EMU-CT***-A are split-type. If split surfaces are not
engaged sufficiently or a foreign object exists between the split surfaces, adequate
performances are not obtained. Pay attention in installation.

10 Troubleshooting
QE83WH4W
10.3.4 Q&A about Connection
Q
Does polarity exist in connection between a current sensor and the module?
A
Yes, it does.
Make connections so that secondary terminals of current sensor (k, l) and terminal symbols of
module agree with each other.
If polarity is incorrect, the current value is measurable, but the electric power and the electrical
energy can not be measured correctly.
Q
Does polarity exist in connection between a voltage transform module and the module?
A
Yes, it does.
Make connections so that output terminals of voltage transform module (PA, PB, PC, PD) and
terminal symbols of module agree with each other.
If polarity is incorrect, the voltage value, the electric power and the electrical energy can not be
measured correctly.
Q
Are there any key points in avoiding errors in wiring?
A
Check polarity of current sensor on the primary current side.
Power supply side of the circuit is indicated as “K,” and the load is indicated as “L.” An arrow
indicates the direction from K to L.
Check the current sensor and the module are connected correctly for the 1-side circuit, 2-side
circuit, and 3-side circuit.
Besides, check that voltage inputs for voltage transform module are connected correctly
among P1, P2, P3, and P0.
Q
How do wires extend between a current sensor and the module?
A
Model EMU-CT***, EMU-CT***-A are extendable up to 50 m.
Model EMU2-CT5-4W is extendable up to 11 m, using together with extension cable. To extend
the wire further, use the current transformer CW-5S(L) for split-type instrument in combination,
extending the secondary wiring on CW-5S(L) side.
10.3.5 Q&A about Setting
Q
Is the setting required?
A
At least, settings of, primary current and input voltage are required. Specify settings in
accordance with a circuit to be connected.
Q
A
If a primary current setting value is different from that of rated current on a connected
current sensor, does it cause a breakdown?
It does not cause breakdown or burning. However, measurement values will be totally
incorrect.
