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-E3-MINI 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 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 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.

Instruction Manual

3.2.- INSTALLATION

The device must be installed on an electric panel or enclosure, attached to a DIN rail (IEC

60715).

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 (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 device 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.

To guarantee the insulation of the device and its category, it is necessary to earth the S2 terminals of the transformers.

The temperature rating of insulation of wires connected to the device will be at minimum 62ºC.

3.3.- PANEL MOUNTING ACCESSORY (72 x 72 mm)

Note: The 72 x 72 mm panel mounting accessory is an accessory that is sold separately.

CIRCUTOR has a panel mounting accessory of the CVM-E3-MINI equipment so that it can be installed on 72 x 72 mm panels.

Figure 1: CVM-E3-MINI with panel mounting accessory�

Figure 2 shows the installation of the panel mounting accessory to the CVM-E3-MINI.

Disconnect all power supplies and measuring equipment from the device before carrying out the installation of the panel mounting accessory.

5�1�3�- MAXIMUM DEMAND

The device calculates the maximum demand of the following:

The Current of each phase.

Three-Phase Active Power.

Three-Phase Apparent Power.

Three-Phase inductive Power.

 Three-Phase capacitive Power.

This value can be displayed on the display screen of the parameter by pressing the and

5�1�4�- HARMONICS

The device can display the voltage and current harmonics, up to the 31st order harmonic, for

each one of the lines, L1, L2 and L3.

A minimum signal level is required to measure harmonics correctly, i.e., a signal level of at least

20 V is required to measure the voltage harmonics and of at least 200 mA to measure the cur-

rent harmonics. If the levels are lower, the unit will not calculate them and will display a value

of 0.

The key jumps to the next harmonics screen.

Press the key to jump from the voltage harmonics to the current harmonics, and from the current harmonics to the home screen of the instantaneous values.

5�1�5�- DETECTION OF INCORRECT CONNECTION AND INCORRECT DIRECTION OF ROTATION

 Incorrect connection or disconnection

The device has a system for detecting the incorrect connection or disconnection of the voltage lines. If this error occurs, the device displays 0 on the lines with a voltage value of less than 50% of the line with the highest voltage value.

 Incorrect direction of rotation

The device has a system for detecting the incorrect direction of rotation of the voltages. In other words, if each of the voltages has been correctly connected to the appropriate terminal, L1 to terminal 10, L2 to terminal 11 and L3 to terminal 12.

If there is an error in the direction of rotation, the icons L1, L2 and L3 ash on the display.

The device has a RS-485 communications parameter, which indicates whether an incorrect direction of rotation has been detected (“7.3.6. DETECTION OF INCORRECT DIRECTION OF

ROTATION”)

Note: The detection of the direction of rotation is only enabled for measurement systems:

Three-phase network measurement (4-3Ph, 3-3Ph y 3-ArOn) and two-phase network measurement with 3-wire connection (3-2Ph).

The CVM-E3-MINI devices have one RS-485 communications port.

The device has as standard two communications protocols: MODBUS RTU ® and BACnet.

The protocol and conguration parameters are selected in the setup menu. (“6.20.- RS-485

COMMUNICATIONS”)

7.1.- CONNECTIONS

The RS -485 cable must be wired with twisted pair cable with mesh shield (minimum 3 wires),

with a maximum distance between the CVM-E3-MINI and the master device of 1200 metres.

A maximum of 32 CVM-E3-MINI devices can be connected to this bus.

Use an intelligent RS-232 to RS-485 network protocol converter to establish the

communications with the master device.

7.3.- MODBUS COMMANDS

Two different memory maps have been implemented for the Measurement, Energy and Voltage

and Current harmonics variables. However, they have the same functions:

 Map 1, uses the addresses of the CVM-MINI device, entering the addresses of the new parameters measured by this new device.

 Map 2, uses the addresses of the CVM-C10 device (adding 0x1000 to all addresses). Except for 3 parameters, the CVM-C10 and the CVM-E3-MINI use the same parameters.

Map 2 should be used if a Modbus map is going to be implemented from scratch. However,

if the map is already being used in another device, use Map 1 for CVM-MINI and Map 2 for

CVM-C10.

7�3�1� MEASUREMENT VARIABLES

All the adresses of Modbus memory are in Hexadecimal.

7�3�6� DETECTION OF INCORRECT DIRECTION OF ROTATION

All the Modbus map addresses are hexadecimal. The function 0x04 is implemented for this variable. This variable indicates whether an incorrect direction of rotation has been detected in the voltages.

Table 29:Modbus memory map: Detection of incorrect direction of rotation�

7D5 0: No fault has been detected

1: Fault detected

7�3�7� DEVICE CONFIGURATION VARIABLES�

All the Modbus map addresses are hexadecimal. The functions 0x04 and 0x10 are implemented for this variable.

The device’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 device will be congured with its default value. The Modbus conguration will not take effect until the device is reset.

7.4.- 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 device features BACNet MS/TP communications, following the specications of ANSI/

ASHRAE 135 (ISO 16484-5).

Using a RS485 connection, the device can connect to a BACnet and include all of the objects

and services defined in the attached PICS map (Protocol Implementation Conformance

Statement). ( “7.4.1. PICS MAP”)

The default speed is 19200 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, 38400

b) #MAC x – where x can be: 0 ... 127

c) #ID x – where x can be: 0 ... 99999

For further information on the protocol: www.bacnet.org.
