Description:

This device can be programmed with special software to display up to 48 alphanumeric messages of up to 24 characters each on two lines. Messages are associated with two connectors located on the back panel of the device according to the attached diagram. The connectors are connected to two interface boards (connector/terminals) using 30 pole-IDC, 1.27-mm pitch flat cable. This allows for speeding up the cabling process. In fact, the device can be mounted directly on the electric panel, and the interface boards can be mounted directly on the internal plate of the cabinet, or in another cabinet. The interface boards are connected by means of screw clamps. Maximum flat cable length: 3 m. A potential-free contact is available on the back of the device. The contact state will change when one or more programmatically associated external alarm contacts are closed or opened.

CEI 1006/30. DIN and Ohmega mount . Dimensions: 90x82 P60 (connector included).

Technical data:

There are 4 keys on the CEI 2052 front panel: PLUS, MINUS, ENTER, ESC.

PLUS KEY: If pressed in alarm display mode, it resets the alarm without storing the message in History. In menu scroll mode, it operates as an increment key.

MINUS KEY: If pressed in alarm display mode, it resets the alarm after storing message in History. In menu scroll mode, it operates as a decrement key.

ENTER: If pressed in the main page mode, it opens up the CEI 2052 main menu. Inside the latter, it is used to confirm a selection. In an alarm state, it enables/disables the buzzer.

ESC: It is used to exit menus and submenus.

By pressing ENTER, the main menu is displayed. The CEI 2052 display shows the first option (SET TIME). Press the PLUS/MINUS keys to scroll through all the other options and press ENTER to confirm the desired choice.

INPUT STATE: It shows the input state in real time, displaying a dot to signify ENABLED and an exclamation point to signify DISABLED.

SEE DAILY ALARMS: When this option is selected, the CEI 2052 device displays the latest event with its code number and the time the event occurred. Use the PLUS/MINUS keys to scroll through all the other events and press ENTER to display the message associated with the selected alarm. Press ESC to go back.

SEE ALARM HISTORY: This option works the same way as the previous one, except that the day and the month when an event occurred will be also displayed.

CLEAR HISTORY: When this option is selected, the display will prompt for the two-digit access code. To input the code press the PLUS/MINUS keys to cycle through the digits, select the desired number for the tens digit, and press ENTER to confirm. Repeat the operation for the units digit. If the correct code has been input, the main page will be displayed whereas the alarm History will now be empty. The Clear History operation must also be performed when the number of messages reaches the maximum number that can be stored. In this case, the CEI 2052 will detect the situation and give out a message warning the user that only X events can still be stored before the storage memory is full.

CHANGE CODE: To change the code, you must input the old code first, following the procedure described for the Clear History option. After that, you will be able to choose a new code.

SET TIMER: This function enables the alarm auto reset after a predetermined time set by the operator. Warning!!! This mode is available only if a monostable type of contact is used (it triggers and returns to its stable state automatically).

BUZZER ON/OFF: It enables/disables the buzzer acoustic signal during alarms.

SET TIME: When the SET TIME function is selected, all the time related data will be displayed (minutes, hour, day, date, month, year). You can set each of these parameters using the PLUS/MINUS keys and the ENTER key to confirm the choice. 'Day' means the day of the week, with Monday set to 1.

When a contact state change takes place (an event has occurred), the buzzer goes off, the display is automatically cleared, and the new alarm message is displayed. In this situation the PLUS/MINUS keys operate differently. If the PLUS key is pressed, the alarm is reset and the message is recorded only in Daily Storage, and will thus be definitively discarded and lost at the end of the day. If the MINUS key is pressed, on the other hand, the alarm is reset and recorded in both Daily Storage and History. If several events are queued, they will be displayed in chronological order, starting with the event that occurred first. By pressing the reset command, the second queued event will be displayed, then the third, the fourth, and so on until the queue is finally empty. It is important to remember to reset the contact before clearing the alarm; otherwise the event will be recorded twice. WARNING!! WHEN THE HISTORY STORAGE MEMORY IS 10 EVENTS AWAY FROM BECOMING FULL, THE USER WILL BE GIVEN A WARNING MESSAGE. PRESS 'ESC' TO RESET THE DISPLAY AND READ THE ALARM MESSAGE.
