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.

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.

2.3.1 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
16
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

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.

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.

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.

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.

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

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).

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

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

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
61
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
62
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
