1. VERIFICATION UPON RECEPTION
Check the following points upon receiving the device:
a) The device meets the specifications described in your order.
b) The device has not suffered any damage during transport.
c) Perform an external visual inspection of the device prior to switching it on.
d) Check that it has been delivered with the following:
- An installation guide,
- 4 Retainers used to attach the device,
- 5 plug-in connectors with screws,
- 1 seal,
If any problem is noticed upon reception, immediately contact the transport com-
pany and/or CIRCUTOR's after-sales service.
2. PRODUCT DESCRIPTION
The CVM-B device measures, calculates and displays the main electrical parameters in single-phase
networks, with and without neutral two-phase networks, balanced three-phase networks, with ARON
measurement or unbalanced networks. The measurement is taken in RMS, via four AC voltage inputs
and four current inputs.
The current measurement is taken indirectly with transformers /5, /1 or with efficient transformers
from the MC1 and MC3 series.
It is a modular device that can be expanded using expansion modules with different functions.
There are 2 device models:
CVM-B100, with a 3.5’’ display.
CVM-B150, with a 5.6’’ display.
The device features:
- 3 keys that allow you to browse between the various screens and program the device.
- 3 indicator LEDs: CPU, ALARM and on the navigation keys.
- LCD Display, for displaying all parameters.
- 2 digital inputs, to select the tariff, detect the logic state of external signals or as act as an
impulse input.
8
CVM-B100 - CVM-B150
Instruction Manual

- 2 transistor digital outputs, fully programmable.
- 2 relay digital outputs, fully programmable.
- RS-485 communications, with two serial protocols: MODBUS RTU ® and BACnet.
The CVM-B can be expanded with the following expansion modules:
M-CVM-AB-8I-8OTR, expansion module with 8 transistor digital inputs and 8 transistor
digital outputs.
M-CVM-AB-8I-8OR, expansion module with 8 relay digital inputs and 8 relay digital outputs.
M-CVM-AB-4AI-8AO, expansion module with 4 analogue inputs and 8 analogue outputs.
M-CVM-AB-Modbus/TCP(Bridge), expansion module for connecting the device to a Mod-
bus/TCP network and as an Ethernet to RS-485 gateway.
M-CVM-AB-LON, expansion module for connecting the device to a LonWorks network.
M-CVM-AB-Profibus, expansion module for connecting the device to a Profibus network.
M-CVM-AB-MBus, expansion module for connecting the device to a M-Bus network.
M-CVM-B-Datalogger, expansion module that can be used to store data in the embedded
PowerStudio platform integrated in the module.
M-CVM-AB-Modbus/TCP(Switch), expansion module for connecting the device to a Mod-
bus/TCP network and as an Ethernet to Ethernet gateway.

3. DEVICE INSTALLATION
3.1.- PRIOR 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
necessary personal protective equipment, and pay attention to the various warnings
indicated in this instruction manual.
The CVM-B device must be installed by authorised and qualified staff.
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.
Also, it is critical to keep the cables in perfect condition in order 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 observe the warnings and/or recommendations set out in this manual, nor for damage
resulting from the use of non-original products or accessories or those made by other manufacturers.
If an anomaly or malfunction is detected in the device, do not use it 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 is installed on a panel. All connections are located inside the electric panel.
Table 2: Panel drill holes for installation.
Model Panel drill hole (according to DIN 43700)
CVM-B100 92+0.8 x 92+0.8 mm
CVM-B150 138+0.8 x 138+0.8 mm
Terminals, opening covers 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.
The device must be connected to a power circuit that is protected with gL fuses (IEC 269) or M fuses,
with a rating of 1 to 2 A. It must be fitted with a circuit breaker or equivalent device for disconnecting
the device from the power supply mains.
10
CVM-B100 - CVM-B150
Instruction Manual

The power and voltage measuring circuit must be connected with cables that have a minimum
cross-section of 1mm2 and the wires must to endure a temperature at least 77 degrees.
The secondary line of the current transformer will have a minimum cross-section of 2.5 mm2.
Current needs to be measured via external current transformers providing reinforced insulation.
3.3.- DEVICE TERMINALS
The CVM-B terminals are distributed between the upper and lower face of the device.
