_____________________________________________
The POWER LED is on when the unit is powered. It is off when the unit is not powered.
The START/STOP button has different functions, depending on the analyzer's
operation. It is used to select the scale desired for the current sensors or to start or stop
the recording of electrical parameters. In this case, to start or stop the recording
process, hold the button during 2 seconds.
(*) The REC LED has three basic modes. When it is off, the unit is not recording
information. When it is permanently on, the unit is recording electrical parameters,
which are stored in the SD memory card. When the REC LED is flashing, there is an
error in the SD memory card. The REC LED can be flashing for the following reasons:
•No memory card inserted in the unit's SD card slot.
•The memory card inserted does not have the correct format or data can not be
written. (for example, if the card is write protected or it has a FAT32 format;
please change the format of the memory card to FAT16).
(**) The LEDs corresponding to L1/sc1, L2/sc2 and L3/sc3 can also indicate different
situations, depending on the unit's status and during the start-up procedure.
•Should the CIR-e³ unit detect a connection of flexible clamps during start-up, the
LEDs can be used to select the scale desired for the current sensors. In this
case, reference will be provided with the legend of the LED shown on the scale
(sc1, sc2 or sc3).
•When you have selected the scale (if needed) or the unit detects clamps with a
single scale automatically (so that the scale selection process is not required),
the LEDs will start flashing to indicate that there is an incorrect connection. The
phase LEDs can start flashing for various reasons:
oIncorrect connection of the voltage references. Flashing indicates that
there is an incorrect phase sequence (L1, L2 and L3).
oThe unit detects power values with a negative sign (as in the case of
generated power).
oThe installation's power factor is under 0.86, i.e., the angle between the
voltage and current corresponding to that phase exceeds 30º. This error
indicates that there is a fault in the unit and we recommend going through
the connections.
CIR-e³ LED’s start flashing to indicate a connection error.
The unit has been installed correctly when the LED’s are permanently on.

5.-BASIC FEATURES
The CIR-e³ analyzer is a programmable measurement unit that measures, calculates
and records the main electrical parameters of single and three-phase industrial
networks in its memory. We must highlight the following concepts:
Serial number: The serial number of CIR-e³ is an important parameter, since all files
generated by the unit must be identified with that number. The 10-digit serial number
is written on the rear features label of CIR-e³.
Programming: The unit is programmed with the setup software CIR-e³.exe. The
application is stored in the SD card supplied with the unit. In addition, the card
records the electrical parameters that are sent to the Web server.
Display (in Cir-e³ Web): The measurement unit includes the right of use of the
associated software that is required to handle the energy data of the CIR-e³ Web
application. It is located in a web site that is active 24 hours a day, 365 days a year:
http://cir-e3.circutor.com.
Installation: The analyzer can be installed to analyze balanced (3 wire) or unbalanced (4
wire) single and three-phase networks. The unit must be powered with the auxiliary
power supply cables in any of the connection options. The auxiliary power supply
cables of the unit are Brown and Green and they correspond to terminals 5 and 6 of
connector B, respectively.
Measurements: The analyzer takes 128 samples per cycle of the voltage and current
variables in true root mean square (TRMS). With all of the samples taken, the unit
calculates the arithmetic mean during the recording period selected by the user. The
analyzer also records the maximum and minimum values measured during each
period. To take these measurements, the analyzer has four voltage sensor inputs
and three current sensor inputs.
Recording: The unit has a 1 Gb external SD memory, FAT16 format, which stores the
parameters measured or calculated by the analyzer. We must highlight the following
features:
•It stores the parameters instantly (measured for a selected period).
•It stores the maximum and minimum values of the recording period selected.
•The SD memory can be expanded to 2 Gb.
•The approximate size of files is as follows, depending on the recording period:
Recording period Recording time Size
1 minute 1 day 1,027 kb
10 minutes 1 day 103 kb
15 minutes 1 day 69 kb
120 minutes 1 day 9.2 kb

6.-INSTALLATION AND COMMISSIONING
CIR-e³ is a portable analyzer that is easy to install and use. It has been designed to
facilitate the work of the companies and/or persons that wish to perform energy audits
(study of consumption) and control the main electrical parameters in an installation.
The study of these parameters is the first step to analyze the response of loads and the
consumption habits of a company or corporation. Without a doubt, the decisions taken
after the study can be focused on a more rational consumption of energy and a
decrease in the power demand of the electricity network.

6.3.2.1.- Configure
Select the configure option to create a new file with the installation's features for a
CIR-e³. The following window will be displayed when you click on “Configure”.
Serial number: Enter the 10 digits of the serial number of the CIR-e³ unit used to take
the measurements. The serial number identifies each individual unit. It is written on a
label on the back of the analyzer: “serial no.” starting with 0102XXXXXX.
The serial number is used by the application as the data name (identifier). The setup
file generated by the application will have the xxxxxxxx.xst format, where “xxxxxxxx”
corresponds to the last eight numbers of the unit's serial number.
Name of the report: You can enter the name of the file for identification purposes. This
field is limited to 16 characters. For example, you can enter the name of the place
where the measurements are going to be taken.
Registration period: The registration period is a value that ranges from 1 to 120 minutes
(2 hours) and it corresponds to a time interval during which we use to store the
average of the records taken. The analyzer takes 128 samples per cycle of the
signals measured. The registration period indicates the interval desired to take the
weighted mean of all samples taken and it stores this value in the memory. For
example, if you select a registration period of 1 minute, the analyzer calculates the
mean of all samples of the variables registered during that minute and stores the
results in the memory. From that period, the analyzer also stores the maximum and
minimum values measured.
Voltage primary: When using transformers to measure the voltage, enter the primary
voltage value of the said transformer. The information related to this feature of the
transformer can be found on a features label on the transformer itself. This label
must indicate the primary ratio.
_________________________________________________________________________________________________________
CIR-e³ User’s Manual 19 of 46

_____________________________________________
In case you are not using voltage transformers and you are taking a direct
measurement (up to 300 V p-n), the value entered must be 1.
Voltage secondary: When using transformers to measure the voltage, enter the
secondary voltage value of the said transformer. The information related to this
feature of the transformer can be found on a features label on the transformer itself.
This label must indicate the secondary ratio.
In case you are not using voltage transformers and you are taking a direct
measurement, the value entered must be 1.
Nominal voltage (V): Enter the nominal voltage value between the installation's phase
and neutral.
Nominal Freq.: Enter the nominal value of the installation's frequency. The range
allowed for this field ranges from 42 to 65 Hz.
Contracted power (kW): You can enter the installation's contracted power (this is only
for information purposes and it does not have an impact on the unit's configuration).
After completing the configuration of CIR-e³, click on “Generate”.
When you select “Generate”, the software automatically creates file xxxxxxxx.xst in the
root directory of the SD card (stored in the default directory). The name file is the same
as the serial number of the unit entered in the setup menu, including the unit's
configuration and installation's characteristics, as shown on the following figure. The unit
will take this configuration when starting the measurements and the data will be
recorded from the SD memory card.
12345678.xst
If you do not generate a setup file, store it in the root directory of the memory card or
when the CIRe³ analyzer can not find the location of the memory card before the
parameter recording process starts, it will automatically load a setup file that has a
series of default parameters defined. The default file loaded by the analyzer is called
“Default” and its features are described on the following figure.
