1.- VERIFICATION UPON RECEPTION

Check the following points upon receiving the unit:
a) The unit meets the specications described in your order. b) The unit has not suffered any damage during transport. c) Perform an external visual inspection of the unit prior to switching it on. d) Check that it has been delivered with the following:
- An installation guide,
- 4 Retainers used to attach the unit,
- 5 plug-in connectors with screws,
- 1 seal,
If any problem is noticed upon reception, immediately contact the transport company and/or CIRCUTOR's after-sales service.

2.- PRODUCT DESCRIPTION

The CVM-B unit 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 efcient transform­ers from the MC1 and MC3 series.
It is a modular unit that can be expanded using expansion modules with different functions.
There are 2 unit models:
CVM-B100, with a 3.5’’ display. CVM-B150, with a 5.6’’ display.
The unit features:
- 3 keys that allow you to browse between the various screens and program the unit.
- 3 indicator LEDs: CPU, ALARM and on the navigation keys.
- LCD Display, for displaying all parameters.

Instruction Manual
CVM-B100 - CVM-B150
- 2 digital inputs, to select the tariff, detect the logic state of external signals or as act as an impulse input.
- 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 tran- sistor 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 out puts.
M-CVM-AB-Modbus/TCP( Bridge), expansion module for connecting the unit to a Modbus/TCP network and as an Ethernet to RS-485 gateway.
M-CVM-AB-LON, expansion module for connecting the unit to a LonWorks network.
M-CVM-AB-Probus, expansion module for connecting the unit to a Probus network.
M-CVM-AB-MBus, expansion module for connecting the unit to a M-Bus network.
M-CVM-AB-Datalogger, expansion module that can be used to store data in the em-
bedded PowerStudio platform integrated in the module.

3.- UNIT INSTALLATION

3.1.- PRIOR RECOMMENDATIONS

In order to use the unit 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 unit must be installed by authorised and qualied staff.
The power supply plug must be disconnected and measuring systems switched off before han­dling, altering the connections or replacing the unit. It is dangerous to handle the unit 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 unit 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 unit, do not use it to take any measurements.
Inspect the work area before taking any measurements. Do not take measurements in danger­ous areas or where there is a risk of explosion.
Disconnect the unit from the power supply (unit and measuring system power supply) before maintaining, repairing or handling the unit's connections. Please contact the after-sales service if you suspect that there is an operational fault in the unit.

Terminals, opening covers or removing elements can expose parts that are hazardous to the touch while the unit is powered. Do not use the unit until it is fully installed.
The unit 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 tted with a circuit breaker or equivalent device for disconnecting the unit from the power supply mains. The power and voltage measuring circuit must be connected with cables that have a minimum cross-section of 1mm2.
The secondary line of the current transformer will have a minimum cross-section of 2.5 mm

3.5.- STARTING UP THE UNIT

CVM-B100 - CVM-B150
Once the CVM-B is connected to the power supply, the following screen,
Figure 11, appears on
the display and checks the integrity of the unit and detects the expansion modules.
Figure 11: Initial check screen of the CVM-B.
When the checking process has nished, the welcome screen is displayed (Figure 12) until the
key is pressed to continue with the start-up.
NB: If 20 seconds elapse without pressing the
key, the unit moves directly to the measure-
ment screen by default.

4.- OPERATION

4.1.- OPERATING PRINCIPLE

The CVM-B is a four-quadrant power analyzer (consumption and generation).
Figure 18: Four quadrants of CVM-B.
Apart from the basic functions of any analyzer, the CVM-B:
Has, for each instantaneous variable, a bar chart that shows the current instantaneous val- ue, maximum and minimum values and the pre-alarm and alarm zones programmed.
Has three display modes, in order to display 1, 3 or 4 variables at the same time on each display. The display of the variables is fully congurable.
It includes as standard the BACnet communications protocol.
It is 100% modular and expandable with different expansion modules which can be includ-
ed in the unit.
It can be easily updated through the microSD card supplied with the unit.
