This manual is a quick guide to the use and operation of
the CVM-MINI-ITF & CMV-MINI-MC with Ethernet
connection. For more information, the whole manual
may be downloaded from CIRCUTOR's web page:

reconnection. The equipment is designed to be changed quickly
in the event of any breakdown.
The CVM-MINI is an instrument which measures,
calculates and displays the main electrical parameters
for three-phase industrial systems (balanced or
unbalanced). Measurements are in true effective value,
via three AC voltage inputs and three AC. current
inputs. (via
MC version). The parameters measured and calculated
are shown in the variables table, paragraph 7.
1.- INSTALLATIO N
The equipment is mounted on DIN rail. Also the device
has to be provided of an magnetic-thermal switch to be
disconnected. The fuses has to be type gl (IEC 269) or
type M between 0,5 to 2 A.
2.- ETHERNET NETWORK SETUP
The configuration software, IPSETUP.EXE, is available
from the CIRCUTOR Web site. It must be executed
under Windows operative system. Once executed it will
appear the following screen

disconnected from the supply. If any operation or
protection fault is suspected the equipment must

3.- DHCP IP assignment
To assign the DHCP name, choose this option using
the arrow on the upper right, and select “On”. Once the
configuration fields have been enabled, enter the
“MAC” address that can be seen on the permanent side
label attached to the device, the format of which is
14:A6:2C:XX:XX:XX. In the “Dirección” field, enter an
unused, temporary IP address, which is within the
working range of your computer. In the “Host Name”
field, enter the DHCP name to be assigned to the
equipment. Optionally, the user can configure the
parameters of the “ClientID” field. The default
“VendorID” of the device is CIRCUTOR.
Once the parameters have been configured click on
"Configurar"
If the equipment is detected into the Ethernet network,
it will appear the following screen.
By clicking "Aceptar" the internal setup WEB page of
the equipment will be displayed.
4.- SETTING (SETUP menu)
(Press SETUP key for 5 seconds)
The
on to the next menu.
The
key validates the information and moves
key allows the different options in a
menu to be selected or increases a digit where a
variable is being entered.
The
key is used to move the cursor
among the digits.
The different options are sequentially described below.
4.1.- Voltage transformer primary
On screen the words "SET PriU" appear followed by 6
digits. These allow the voltage transformer primary to be
set (from
1 to 100,000).
4.2.- Voltage transformer secondary
On screen the words "SET SEcU" appear followed by 3 digits.
These allow the voltage transformer secondary to be set (from
1 to 999).
4.3.- Current transformer primary
The display show "SET PriA" followed by 5 digits. These allow
the current transformer primary to be set (from
1 to 10,000).
In the case of using a transforming system type MC1,
introduces the primary of the transformer
corresponding to the relation of the selected physical
wiring. In case of using type MC3, introduces the value
of the primary that appears in the label of the
transformer.
4.4.- Current transformer secondary.
The display show "SET SecA". In the ITF versions, selection is
allowed between 1 and 5 A. In the MC version, this parameter
is not available in the equipment configuration menu.
4.5.- Measurement in 2 or 4 quadrants (power
consumption and/or generation).
On screen the words “
(
2=Power consumption / 4=consumption and
SET QuAd” appear
generation)
4.6.- Setting the Power demand meter:
a) Electrical parameter to control: ("SET Pd Code"):
In the field "MAC" it must be typed the physical address
of the unit using scripts as separator, this data is
showed on to the lateral label of the equipment and the
format is 14:A6:2C:XX:XX:XX.
In to the field "Dirección", type the assigned IP
address to the equipment into the local area network
Into the field "Netmask" type the mask for the network.
In case of routing the equipment in a different network,
setup the field "Gateway" with the IP address of the
device that allows the route. For example, if the
equipment must be accessible from Internet, will be
necessary setup the IP address for the ADSL router
that allows the Internet connection. Also the router will
need convenient programming to allow Internet enroute
and enable the traffic from/to the CVM-MINI-Ethernet.
If it is not the case leave the filed "Gateway" in blank.
If the equipment is not detected on the local network it
will appear the following screen.
Review the settings assigned to the computer, check
the connection to the router and the Ethernet
Connector LEDs are lit and / or blink. The LED on the
left side of the connector is the link status and the LED
on the right side indicates activity receive / transmit TX
/ RX. Both can be lit in green or amber color. If
everything appears correct, consult with your admin for
the local area network.

6.- CVM-MINI-Ethernet COMMUNICATIONS
One or more analysers CVM-MINI-Ethernet can be
connected to a "router" or "switch" Ethernet and access
their information through a PC connected to the same
Ethernet local area network. This system allows
centralizing data on a single registration point (Studio ®
Power System).
To change the communication settings see section 2.
The network analyzer type CVM-MINI-ETHERNET
communicates using MODBUS TCP © (Pulling
Question / Answer).
*Variables only valid if the Maximum Demand for current has been set per phase.
