This manual is intended to be used as a guide in the
installation, conguration and operation of the CVMk2
network analyzer, for optimising the system's benets.
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
conguration menus. Prior to using the analyzer, read the following sections carefully: power
supply, connection and conguration. 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.
• Class 0,2 or 0,5 in Power and Energy (*).
• Real time, maximum and minimum values for each parameter with date and time.
• 1/4 VGA graphical display.
• RS-485 (Modbus/RTU©) communication incorporated.
• Possible to congure the display screen as the MASTER for 32 measurement modules.
• Multi-tariff equipment (allows to program up to 9 tariff)
• Memory of present, month and annual energy consumed and generated.
• Graphical display of wave forms and voltage and current phasors.
• 8 digit (100 GW·h) counter to track energy consumed and energy generated.
• Recording of power supply quality events on voltage.
• Expandable with inputs/outputs expansion card.

(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
be blocked, i.e. opened prior to dismounting.
CVMk2
A zoomed view of the previous image is provided in the
figure. It provides a detailed view of the movements
necessary to lock and unlock CVMk2 display screen
mount ring.
As shown in the gure, the guide arrow should point
upward and line up with the arrow found on the rear of
the viewer or display screen. The arrow points to the
position where the RJ-45 communications cable and
the display screen power supply cables run out.
The mount diagram is shown in the following gure. The measuring unit can then be mounted
on the ring behind the display screen, or it can be installed on a DIN rail and communicate
with the display screen via a communication cable and transparent RJ-45 power supply. (See
Table 3.1, physical description).
To install the screen in a panel as shows the 2.3 installations methods, you
have to use a at surface of a type 1 enclosure.

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.
