(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.

2.3.1 PROCEDURE

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 figure, 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 figure. 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 flat 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 firmware version on the display screen. After a time of searching, it will also display the firmware 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.
