1�- VERIFICATION UPON RECEPTION

Check the following points when you receive 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,

- 2 Retainers used to attach the unit,

- 5 connectors.

If any problem is noticed upon reception, immediately contact the transport company and/or CIRCUTOR's after-sales service.

2�- PRODUCT DESCRIPTION

The CVM-C10 unit measures, calculates and displays the main electrical parameters of the following networks: single-phase, two-phase, with and without neutral, balanced three-phase, with ARON measurements or unbalanced. The measurement will be taken in RMS with the three AC voltage inputs and three current inputs.

There are 3 versions of the unit, depending on the type of current input:

 CVM-C10-ITF, indirect current measurement with /5A or /1A transformers.  CVM-C10-ITF-IN, indirect current measurement with /5A or /1A transformers and an

input to measure the neutral current.  CVM-C10-MC, indirect current measurement with efcient transformers of the MC1 and MC3 series.  CVM-C10-mV indirect current measurement with /0.333V transformers.

The unit features:

- 3 keys that allow you to browse between the various screens and program the unit.

- 3 indicator LEDs: CPU, ALARM and KEY.

- LCD display, displays all parameters,

- 2 digital inputs, used to select the tariff or detect the logic state of external signals.

- 2 digital outputs, fully programmable.

(Not available in the CVM-C10-ITF-IN model)

- 2 alarm relays, fully programmable.

- RS-485 Communications, with two serial protocols: MODBUS RTU© and BACnet.

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-C10 unit must be installed by authorised and qualied staff.

The power supply plug must be disconnected and measuring systems switched off before han-

dling, 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 heed 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 danger-

ous 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.

3.2.- INSTALLATION

The unit will be installed on a panel (92

+0.8

x 92

+0.8

mm panel drill hole, in compliance with DIN

43700). All connections are located inside the electric panel.

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 (IEC 269) or M type fuses with a rating of 0.5 to 2 A. It must be tted with a circuit breaker or equivalent device, in order to be able to disconnect the unit from the power supply network. 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 mm2.

4.3.- DISPLAY

The unit has a backlit LCD display showing all the parameters listed in Table 3. The display is divided into four areas (Figure 14):

Figure 14: CVM-C10 Display areas

 The area with data per phase displays the instantaneous, maximum and minimum values of each phase being measured or calculated by the unit.

The total data area displays the totals of the values being measured or calculated by the unit.

Analogue bar, displays the % of the current power of the installation.

Cos φ - PF Bar, displays the value of the system's Cos φ or power factor in real time.

4�3�1� COS φ - PF (POWER FACTOR) BAR

Figure 15: Cos φ - PF Bar

This bar displays the value of the installation's cos φ or power factor in real time. The parameter that will be displayed is selected on the programming menu. ( “4.9.13. Selecting

the Cos φ - PF bar on the display”)

Instruction Manual

25

4�3�2� ANALOGUE BAR

Figure 16: Analogue Bar

The analogue bar displays two parameters:

 Current power of the installation in %

This parameter is displayed in 12 divisions, each one represents 10%, into which the analogue bar is divided.

The unit calculates the current power of the installation using the formula:

P = V*I*cos(φ)

Where the voltage and the cos(φ) are the installation’s current values.

The current is referenced in its full scale. (100% is the full scale of the unit and a value above 100% indicates that it is out of range).

CVM-C10

 The maximum system demand reached, i.e., the maximum power value reached since the unit was started, expressed as a percentage.

This value is displayed with the icon .

The value and the maximum and minimum values are reset. ( “4.9.14. Deleting maximum

and minimum values”)

Example: Figure 16 shows that the installation performance is 50% and that the maximum de-

mand of the system is 80%.

4�3�3� OTHER SYMBOLS ON THE DISPLAY

The following are also shown on the display:

 Type of installation

The type of installation to which the unit is connected can be selected on the programming menu, ( “4.9.8. Type of installation”). The selected type is shown on the top left of the display.

 State of digital inputs

If the digital inputs have been activated, the top left of the display will show the icons that indicate that the digital input is active.

The unit’s Modbus function does not check whether the variables recorded are within the correct margins, they are only checked when they are read from the EEPROM. So if any parameter is recorded with an incorrect value the unit will be congured with its default value. The Modbus conguration will not take effect until the unit is reset.

4�10�4� BACnet PROTOCOL

BACnet is a communications protocol for Building Automation and Control NETworks. This

protocol replaces the proprietary communications of each device, making it a set of common communication rules that enables the complete integration of the building automation and control devices of different manufacturers.

The unit features BACNet MS/TP communications, following the specifications of ANSI/ ASHRAE 135 (ISO 16484-5). Using a RS485 connection, the unit can connect to a BACnet and include all of the objects and services dened in the attached PICS map (Protocol Implementation Conformance Statement).

( “4.10.5. PICS MAP”)

The default speed is 9600 bps and the MAC is 2 (node number), and can be changed on the conguration screen or by entering the BaudRate and MAC_Address variables. The identier (Device_ID) can be changed on the conguration screen using the writing property over the variable or through the Device_ID variable.

Another option is to overwrite the Object_Name in the Device object: a) #Baud x – where x can be: 9600, 19200 b) #MAC x – where x can be: 0 ... 255 c) #ID x – where x can be: 0 ... 999999
