1. INTRODUCTION

This manual is intended to be used as a guide in the installation, conguration and operation of the CVMk2 network analyzer, for optimising the system's benets.

Read with attention and follow the warnings and symbols.

1.1 DESCRIPTION

CVMk2 measures, calculates and displays the primary electric parameters in balanced or

unbalanced three-phase industrial networks. True RMS values are measured using three alternating voltage inputs, two voltage references (neutral and ground), and four current inputs to measure secondaries …/1A or …/5A, coming

from the outside current transformers. It should be considered that when secondary .../1 is selected, the calculation is made by the software.

The CVMk2 network and power supply quality analyzer is a programmable measuring instrument. It offers a wide variety of uses, which can be selected from the instrument's conguration menus. Prior to using the analyzer, read the following sections carefully: power supply, connection and conguration. Then, choose the best operating method for obtaining

the desired data.

CVMk2 permits viewing the electric parameters on a backlit 1/4 VGA graphical display. Real

time, maximum or minimum electric parameters can be viewed by pressing the corresponding

key. Internal processor shows more than 500 electric parameters via the display screen and

communication. Said parameters may be fed from a single or three phase system.

CVMk2 has the following important features:

• Outside dimensions 144x144x116 mm.

• Mounted on a DIN rail (measurement module) with display screen on panel (96x96 mm, 144x144 mm or 103 mm (4") diameter hole.

• True RMS value (TRMS) measurement.

2. INSTALLATION

This manual provides information and warnings that the user should heed to guarantee that the system operates safely and is kept in good conditions for safe use.

If the system is handled in a way contrary to the manufacturer's specications, it

may not be protected.

2.1 ITEMS TO VERIFY UPON RECEPTION

Verify the following upon receiving the instrument:

• The device meets specications in the order.

• The device was not damaged during transport.

• The instrument comes with the quick guide and/or the user's manuals.

In order to safely use the CVMk2, the personnel in charge of installing or handling it must follow the standard safety guidelines and heed all warnings provided in the instruction manual.

This analyzer should be installed and maintained by qualied personnel.

2.2 ASSEMBLY SITE

ENVIRONMENTAL CONDITIONS

To guarantee its optimal operation, it is recommended to use the system at between -10 and 40 ºC with relative humidity between 5 and 95%, but with no condensation. Temperature range

according UL. In internal testing until 50 ºC

CONSIDERATIONS

The CVMk2 should be mounted in a distribution cabinet that protects the system from environmental contamination such as oil, moisture, dust, corrosive vapours or other volatile substances.

When it is likely that the system has lost its safety guards (due to visible damages), it should be disconnected from the auxiliary power supply and the input supplies. In this case, contact a qualied tech support.

The system can be installed in one of two basic ways:

• As a compact system in a distribution cabinet, installing at the panel.

• As a modular system, installing the display on the panel and the measuring module on DIN 46277 (EN 50022) rail.

2.3 INSTALLATION METHODS

The gures illustrate the different installation possibilities, permitted by the display screen design. The system design facilitates screwing the panel on (92

+0.8

mm and a 103 mm diameter hole).

2.3.1 PROCEDURE

The figures illustrate how to mount the front part (display) in a 92x92 mm (3,62 x 3,62 in) hole, a 103 mm (4,06 in) diameter hole and in a 138x138 mm ( 5,43 in) hole.

After inserting the front part, install the mount ring,

making sure that the tabs are not blocked (see procedure). Also, assure that the white arrow, which

indicates the point where the communications cable and the RJ-45 display screen power supply cable run out, lines up with the arrow on the measuring equipment.

INTRODUCTION

The tabs are components used to fasten the system to

the panel. When mounting the system, the tabs must be

free, and unblocked, so that as pressure is applied to

the mount ring the tabs go over the clamp zipper teeth. Similarly, to dismount the panel display the tabs should

3.2. START-UP

Before power ON the device, make sure that all the cables are properly connected. A bad connection can cause serious injuries to the personnel that are working on

the equipment and can damage the equipment.

When power supply is connected to the CVMk2, the system will show an initial presentation

and initialize its internal software indicating the rmware version on the display screen. After a time of searching, it will also display the rmware versions of the modules that are connected to the COM 1 DISPLAY port as well as the cards that are inserted in each one of the modules.

Once initialization is complete, the CVMk2 will display the switched module's real time values on the main screen.

The CVMk2 principal screen changes. This is because the system will keep a memory the last screen that was viewed for more than 20 seconds before disconnected. This screen will be displayed the next time the display is turn on except if it is an expansion card screen. They

are not stored in memory.

Once the CVMk2 has been installed, is recommended to restart the meter and the

maximums and minimums of the device. It is possible that the installation process

will produce some recorded parameters outside the range of normal working and

subsequently affect the display of records in graphs or tables.

To save the modied parameters to memory, press OK (F4) before exiting. If saving the changes

is not desired, press ESC (F3).

Parameters that can be congured on this screen are:

• SWELL Thr: This corresponds to the threshold value, in %, to detect an overvoltage event.

• SAG Thr: This corresponds to the threshold value, in %, to detect a hole event.

• iNTEr. Thr: This corresponds to the threshold value, in %, to detect a short circuit event.

• SWELL Hys: Hysteresis, in %, over the programmed value in the detection threshold.

• SAG Hys: Hysteresis, in %, over the programmed value in the detection threshold.

• iNTER. Hys: Hysteresis, in %, over the programmed value in the detection threshold.

The value of the hysteresis is always, in part, more restrictive. It is not a symmetric hysteresis. The detection value is over the programmed value, as a %. The hysteresis applies in the disconnection or the disappearance of the event.

If the event is for a maximum (over v Thd), the hysteresis will be applied when the signal drops. If the event is for a minimum (hole Thd and short circuit Thd),

the hysteresis will be applied when the signal increases again.

In the graph is showed an example of an Swell voltage in the interval t 0. The time of that overvoltage event is the time that the signal is over the swell value (usually 110%) plus the time of the hysteresis for this swell (usually 2%).

CONFIGURATION

CVMk2

Another example of event are showed in times period t1, t3 and t4. They are Sags. They are congured usually unther 90% of the nominal voltage.

When the voltage goes down unther 10% it is stored as an interruption. That interruption is

showed in period t2.

Thre quality events has to be longer than 10ms. If the duration is less than 10ms, the event will

not be stored but will affect to the calculus of the average value for that period.

To access the maximum demand control parameters conguration screen, position the cursor over DEMAND and conrm by pressing SET.

CONFIGURATION

Parameters that can be congured on this screen follow:

Period: Integration window minutes used calculating the maximum demand. Values can

be programmed from 1 up to a maximum of 60.

Win. type: It is possible to select between two window types to calculate the maximum

demand. These are:

• FIXED: Each period duration initializes the maximum demand value. If

programmed for 15 minutes, the measured values are integrated every 15 minutes, and the values for the next 15 minutes are set to zero.

• MOVING: The beginning and end of the integration period moves with each sample collected. The calculation for maximum demand is made with the

values, in the integration time, each time a new sample is recorded.

To store the modied parameters in memory, press SET and conrm with OK (F4). To exit without

saving changes press ESC (F3).

To access the conguration of the card with 8 digital inputs and 8 digital outputs, enter the conguration menu (menu ---> setup.) and in the EXP.CARD menu, select the position where the card is inserted. To modify the card conguration parameters, press the EDIT button (F4).

The parameters congured on the alarms screen have different meanings depending on the electric variable chosen on the conguration line, Var. Code. (See Chapter 8.3, Modbus Memory

Map, to see the codes for all variables.)

Two types of electric variables are distinguished to congure an alarm.

- One real time value that is measured or calculated by the analyzer. (type a).

- Assigned an output for impulses (kW·h). One example of this type of variable can be consumed active energy with code 129 (type b).

CONFIGURATION

CVMk2

4.7.1.1. Alarm conguration

When cards conguration is accessed, the following menu will appear for

var. code:

an energy variable to which an impulses output is assigned.

Maximum

electric variable should be congured. This should be considered as a

maximum value alarm. If energy variable was selected, the weight of the pulse, that the alarm will have

should be provided in W·h.

Example: If

impulse every 10W•h.

Minimum

variable should be congured. This should be considered as a minimum value

alarm.

If energy variable is selected, it is not necessary to congure this parameter.

The code entered in this variable may be an instantaneous electric variable or

If instantáneous variable was selected, the maximum value of that real time

000.010

If intantaneous variable is selected, the minimum value of the real time electric

is entered, the alarm will activate every 10W•h. Will generate an

ALARM 01

Delay. ON: If instantaneous variable is selected, it corresponds to the minimum time in

seconds that the condition must be activated to turn on the alarm.

Example: If 000002 value is programmed, the alarm will be activated after 2 s.

If energy variable is selected, this value corresponds to the time ON

impulse. This is the number of 10 ms steps that the alarm will be activated to

generate the impulse.

Example: If the 000010 value is programmed, the alarm will be activated during 100ms.

Delay. OFF: If instantaneous variable is selected, it corresponds to the minimum time in

seconds that the condition must desactivated, to turn off the alarm.

Example: If 000003 value is programmed, the alarm will be desactivated after 3 s.

If energy variable is selected, this value corresponds to the time OFF impulse.

This is the number of 10 ms steps that the alarm will be deactivated to generate

the impulse.

Example: If 000010 value is programmed, the alarm will be desactivated during 100ms

To access the conguration for alarm 2 and subsequent alarms, press the Next button (F2). The conguration screens for all the alarms, up to a maximum of 16 alarms, can be accessed

4.7.1.1.b Reverse conguration logic output

When a variable code corresponding to the status of an expansion card input is selected, an

alarm can be activated in one of two possible ways: direct or inverse logic.

To congure the alarms using direct logic, with respect to the input, [i.e., the alarm activates (value = 1) when the input activates (value = 1)], the parameters should be congured as follows:

max = 1 and min = -1.

To congure the alarms using inverse logic, with respect to the input, [i.e., the alarm activates (value = 0) when the input deactivates (value = 1)], the parameters should be congured as follows:

max = 0 and min = 0.

4.7.1.2. Digital outputs conguration

On this screen, equations are congured for the alarms that are applied to activate the system outputs. Equations can be congured using AND (*) and/or OR (+) functions between one or more of the 16 previously congured alarms (see Section 4.7.1.1., Alarm Conguration), in order to activate each one of the card's 8 digital outputs.

To modify the card equations' conguration parameters, press the EDIT button (F4). Select the output to be congured and press SET to begin editing.

Edit the two digits in the equation that correspond to the appropriate alarm. Between the two digits corresponding to the alarm, an "*" or "+" sign can be entered. These correspond to the AND or OR functions, respectively, and will be applied between the alarms congured.

Press (F3) to return to the ALARM 01 screen (Section 4.7.1.1). Press (F1) to return to the inputs screen (Section 4.7.1.3).

CONFIGURATION

WARNING: The value 00 in an outputs activation equation means that nothing at

all should be done. Thus, it should only be entered at the end of the equation. If

the value 00 is entered at the beginning of the equation, the CVMk2 will not make the calculation or activate the corresponding output.

4.7.1.3. Digital inputs conguration

CVMk2

The card inputs are also congured in two different ways depending on whether the user desires to congure the input as an incremental counter or a two-state logic input (ON/OFF).

size = 0000

Accordingly, the input is congured as a two-state input, ON/OFF. When the input is congured as ON/OFF, it is not necessary to congure the next menu option, Dec. pos.

size ≠ 0000

When an input size other than zero is congured, this is congured as an incremental pulse counter, which can have a maximum counter value of 10M. The value to enter is the multiplier

for each input pulse.

Dec. pos: Indicate the decimal positions that the corresponding input counter should

have.

The options available in the lower menu include:

Next(F2). This increases the input number from 1 to a maximum of 08 to access its

conguration. From the 08 input conguration screen, pressing F2 (Next) again will take the user back to the 01 input conguration screen.

Read Section 4.7.0., Inserting

Expansion Cards.

To access the conguration of the card with 8 digital inputs and 4 relay outputs, enter the conguration menu (menu ---> setup.) and in the EXP. CARDS menu, select the position where

the card is inserted.

To modify the card conguration parameters, press the EDIT button (F4).

The parameters congured on the alarms screen have different meanings depending on the electric variable chosen on the conguration line, Var. Code, (See Chapter 8.3, Modbus Memory

Map, to see the codes for all variables.)

Two types of electric variables are distinguished to congure an alarm.

- One real time value that is measured or calculated by the analyzer. (type a).

- Assigned an output for impulses (kW·h). One example of this type of variable can be active energy consumed with code 129 (type b).

CONFIGURATION

4.7.2.1. Alarm conguration

CVMk2

When cards conguration is accessed, the following menu will appear for

var. code:

an energy variable to which an impulses output is assigned.

Maximum

electric variable should be congured. This should be considered as a

maximum value alarm. If energy variable was selected, the weight of the pulse, that the alarm will have

should be provided in W·h.

Example: If

impulse every 10W•h.

Minimum

variable should be congured. This should be considered as a minimum value

alarm.

If energy variable is selected, it is not necessary to congure this parameter.

The code entered in this variable may be an instantaneous electric variable or

If instantáneous variable was selected, the maximum value of that real time

000.010

If intantaneous variable is selected, the minimum value of the real time electric

is entered, the alarm will activate every 10W•h. Will generate an

ALARM 01

Delay. ON: If instantaneous variable is selected, it corresponds to the minimum time in

seconds that the condition must be activated to turn on the alarm.

Example: If 000002 value is programmed, the alarm will be activated after 2 s.

If energy variable is selected, this value corresponds to the time ON

impulse. This is the number of 10 ms steps that the alarm will be activated to

generate the impulse.

Example: If the 000010 value is programmed, the alarm will be activated during 100ms.

Delay. OFF: If instantaneous variable is selected, it corresponds to the minimum time in

seconds that the condition must desactivated, to turn off the alarm.

Example: If 000003 value is programmed, the alarm will be desactivated after 3 s.

If energy variable is selected, this value corresponds to the time OFF impulse.

This is the number of 10 ms steps that the alarm will be deactivated to generate

the impulse.

Example: If 000010 value is programmed, the alarm will be desactivated during 100ms

To access the conguration for alarm 2 and subsequent alarms, press the Next button (F2). The conguration screens for all the alarms, up to a maximum of 16 alarms, can be accessed

Expansion Cards.

To access the Ethernet and μSD memory card conguration, enter the conguration menu (menu ---> setup.), and in the EXP.CARD menu, select the position where the card is inserted.

CONFIGURATION

In the Ethernet and μSD memory card conguration screen, it is possible to delete every le saved to the memory. The data saved is basically separated into two formats as seen in the gure: quality events with the *.EVQ extension and the standard registries with the *.STD

extension.

A single *.EVQ events le is generated, in which are stores all the quality voltage events. The *.STD les are automatically generated every day.

CVMk2

WARNING: When an μSD card is installed in the system, it is automatically

formatted. It is recommended not to install cards with documents that should be preserved.

The card format should be FAT 16 and the maximum capacity is 2 Gb. Neither FAT 32 nor HCSD formats are accepted.

To modify the card conguration parameters, press the EDIT button (F4). Select the option to be congured and press SET to begin editing.

It is possible to select between yes or no values using the up/down arrow buttons, and the

selection is conrmed with the ok key.

Edit screen options follow:

ESC: Exit the current menu without saving changes. OK: Save the changes made and exit the edit screen.

Parameters that can be congured on this screen follow:

Delete std: Delete the last day stored in μSD memory (*.STD). Delete evq: Delete the quality le stored in μSD memory (*.EVQ). Format: Delete all les stored in μSD memory.

4.7.4.1. Network and communications Protocol

The CVMk2's Ethernet card and μSD memory are specically designed to communicate in Ethernet networks with Modbus/TCP protocol.

With this system, all the RS-485 communication BUS wiring is extraordinarily optimised, thus

optimising the IT infrastructure already created and facilitating its installation.

4.7.4.2. IP Address Conguration

WARNING: The IP assigned to the CVMk2 with the arp commands is temporary and the system will recover its original IP when it loses the power supply. To save the new IP in the system, enter the conguration menu, verify the modications and exit the menu after saving changes. Accordingly, the new IP will be saved in the analyzer.

The ARP commands can be used to congure the Ethernet card's IP address.

As for the Windows ARP command, the PC ARP table must have at least one IP address dened in addition to its own IP address. If the ARP table is empty, the command will return

an error message. From a command window, type in "arp-a", to verify that there is at least one

entry in the ARP table. If the ARP table does not exist or the machine using it is the only one in the table, ping any other IP address on the network to generate a new entry in the table. As example if you want to congure the IP address 172.16.14.254 and the MAC address of

the card is 00-20-4A-8D-66-66

CONFIGURATION

CVMk2

a) Once that is done, enter the following command to assign the IP address to the

expansion card connection.

c:\ arp -s 172.16.14.254 00-20-4A-8D-66-66

b) Now, execute a telnet to port 1. ( For some versions of Windows the command Telnet

come deactivated). The connection attempt will always fail, but the CVMk2 will change its IP to the one previously assigned.

c:\ telnet 172.16.14.254 1

c) Finally, execute a telnet to port 9999 and congure all the required parameters. Then,

it is possible to begin conguration of the expansion card's Ethernet converter. It is very important to save the changes before exiting the conguration menu. Example:

c:\ telnet 172.16.14.254 9999

The conguratios screen is as follow

CONFIGURATION

In this menu you can configure all options of CVMk2 ethernet card. Once the desired conguration exit the application must exit saving changes

The speed set in the conguration menu CVMk2 ethernet port must match the speed congured on the device itself (see chapter 4.6 Communications). If no

match, the device did not communicate properly with the application or master.

Connection with the master system is made with Ethernet cables consisting of four pairs of twisted pair wires (screened). The card is connected on one end while the corporate network's electronics (hub or switch) is connected on the other end.

If a computer or device is directly connected through its Ethernet port, the Ethernet cable wiring

should have a special provision for said communication.

It is also possible to congure the CVMk2's expansion card IP address using Power Studio or PowerStudio Scada by CIRCUTOR. (Said software can be downloaded from www.circutor.

com). Once installed, the CVMk2 Ethernet Modbus/TCP device should be selected, as illustrated in the gure:

CVMk2

You must assign a name and the desired IP address. The IP address must be in the same address limit than does the computer. This step will fail because they do not nd the device with the IP that was assigned and display the next screen to request the MAC address of the

card.

You must enter the MAC address of the ethernet card and click accept. The software sends the new IP

address to the expansion card analyzer
