Instruction Manual

1�- VERIFICATION UPON RECEPTION

Check the following points upon receiving the device:

a) The device meets the specications 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

company and/or CIRCUTOR's after-sales service.

2�- PRODUCT DESCRIPTION

The CVM-A measures, calculates, displays and records the main electrical parameters and

the quality parameters in single-phase networks, two-phase networks with and without neutral,

balanced three-phase networks, with ARON (1) measurement or unbalanced. The measurement

is taken in TRMS, via four AC voltage inputs and four or three current inputs (according to ver-

sion).

There are 2 device models:

CVM-A1000, with a 3.5’’ display.

CVM-A1500, with a 5.6’’ display.

There are 2 versions of the device depending on the current input:

CVM-A1x00-ITF, the current is indirectly measured using /5, /1 A transformers or efcient

MC1 and MC3 series transformers and an input for neutral current measurement.

CVM-A1x00-FLEX, current measurement using Rogowski sensors. As there is no meas-

urement input, the device calculates the neutral current.

(1)The CVM-A1x00-FLEX version includes an ARON connection.

Instruction Manual

CVM-A1000 - CVM-A1500

It is a modular device that can be expanded using expansion modules with different functions.

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.

- 2 transistor digital outputs, fully programmable.

- 2 relay digital outputs, fully programmable.

- RS-485 communications, with two serial protocols: MODBUS RTU ® and BACnet.

- Built-in Datalogger module, which can be used to check data via a conventional web

browser. The PowerStudio external software is needed to download the data to a PC or

server.

The CVM-A 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 device to a

Modbus/TCP network and as an Ethernet to RS-485 gateway.

M-CVM-AB-LON, expansion module for connecting the device to a LonWorks net-

work.

M-CVM-AB-Probus, expansion module for connecting the device to a Probus net-

work.

M-CVM-AB-MBus, expansion module for connecting the device to a M-Bus network.

M-CVM-AB-Modbus/TCP(Switch), expansion module for connecting the device to a

Modbus/TCP network and as an Ethernet to Ethernet gateway.

Instruction Manual

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 vari-

ous warnings indicated in this instruction manual.

The CVM-A device 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 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 danger-

ous areas 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 3: Panel drill holes for installation�

Model Panel drill hole (according to DIN 43700)

CVM-A1000 92+0.8 x 92+0.8 mm

CVM-A1500 138+0.8 x 138+0.8 mm

Terminals, opening covers or removing elements can expose parts that are haz-

ardous to the touch while the device is powered. Do not use the device until it is

fully installed.

Instruction Manual

CVM-A1000 - CVM-A1500

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 tted with a circuit breaker or equivalent device for

disconnecting the device from the power supply mains.

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.- CVM-A1x00-FLEX: ROGOWSKI SENSORS

The CVM-A1x00-FLEX model measures currents using exible sensors, based on the Ro-

gowski coil principle.

The exibility of the sensor allows it to measure an alternating current irrespective of the posi-

tion of the conductor.

CIRCUTOR has a Rogowski sensor model that can be used with the CVM-A1x00-FLEX�

Table 5 shows the connection of the sensors and Table 4 the maximum position error.

Note: For more information, consult the corresponding sensor guide.

Figure 3: Three-phase measuring with a 4-wire connection (transformer secondary: /1A, /5A or MC1 (/0�250))�

Note: The device can calculate the neutral current without having to measure it, option:

Calculated current .

The MC1 transformer secondary value is set to 0.250 A

The transformer for measuring the LN neutral current cannot be MC type.
