3.1.- PRELIMINARY RECOMMENDATIONS
In order to use the device safely, it is critical that individuals who handle it follow the
safety measures set out in the standards of the country where it is being used, use the
personal protective equipment necessary, and pay attention to the various warnings
indicated in this instruction manual.
The CVM-NET4+-MC device must be installed by authorised and qualified personnel.
The power supply plug must be disconnected and measuring systems switched off before handling, al-
tering the connections or replacing the device. It is dangerous to handle the device while it is powered.
It is critical to keep the cables in perfect condition to avoid accidents, personal injury and damage to
installations.
The manufacturer of the device is not responsible for any damage resulting from failure by the user
or installer to heed the warnings and/or recommendations set out in this manual, nor for damage
resulting from the use of products or accessories that did not come with the device or that were made
by other manufacturers.
If an anomaly or malfunction is detected in the device, do not use the device to take any measurements.
Inspect the work area before taking any measurements. Do not take measurements in dangerous ar-
eas or where there is a risk of explosion.
Disconnect the device from the power supply (device and measuring system power
supply) before maintaining, repairing or handling the device's connections.
Please contact the after-sales service if you suspect that there is an operational fault
in the device.
3.2.- INSTALLATION
The device must be installed in an electric panel or enclosure and fastened to a DIN rail (IEC 60715).
Terminals, opening roofs or removing elements can expose parts that are hazardous to
the touch while the device is powered. Do not use the device until it is fully installed.

4.3.- DIGITAL OUTPUT
The device is equipped with 4 digital transistor outputs, terminals 7, 8, 9, 10 and 11 of Table 3.
4.4.- CONFIGURATION
As the device has no keypad, the setup parameters must be sent to the device via Modbus/RTU©
commands, or using the CIRCUTOR PowerStudio Software, which can be downloaded for free from the
web site www.circutor.es.
All MODBUS map addresses are hexadecimal.
4.4.1- CONFIGURATION OF THE COMMUNICATION PARAMETERS
Two options are available for this:
4.4.1.1.- Using the peripheral number
The device has the following default communication parameters: peripheral 4, 19200/8/N/1. The
following records are available for changing the peripheral number or speed:
Table 4:Configuration of the communication parameters using the peripheral number.

RX: NP 10 2742 0006 CRC
4.4.1.2.- Using the serial number (BROADCAST)
The serial number of the device can be found on the device's side label (E.g.: 1280000001). This
number must be translated into hexadecimal language so that the sentence can be sent to the device
in broadcast format (peripheral 00):
1280000001 (Decimal) → 4C4B4001 (Hexadecimal)

4.4.8.3. Configuration of digital outputs
Digital outputs, in addition to being remotely managed, can be used as alarm elements, associated
with an electric variable by a maximum or minimum value, or can carry out the power impulse function
associated with any power consumption parameter (active or reactive).
The following input table is provided to programme them Table 14:

Note: When a power variable is selected, the unit automatically recognises the power impulse function
and applies the w·h value of the first record. The pulse width value is in milliseconds
Example of alarm programming by maximum and minimum value with voltage VL1:

4.4.9. CONFIGURATION OF ACQUISITION CHANNELS
The CVM-NET4+-MC can configure the 3 current inputs of its 4 channels as three-phase or single
phase.
If configured as three-phase, the currents will be automatically associated with the voltages, as fol-
lows: 1S1 to VL1, 2S1 to VL2 and 3S1 to VL3.
If configured as single-phase, the configuration will associate the voltages with the currents, as follows:

Example of programming the acquisition channels:
Program 3 three-phase channels (Channels 1, 2 and 3) and one single-phase channel (Channel 4) and
associate the 3 currents with the same voltage VL1. Once these installation requirements are set forth,
proceed with the following configuration:
