5. BASIC REQUIREMENTS AND OPERATIONAL SAFETY

In the safety service scope, the display meets the requirements of the EN 61010-1 standard.

- All operations concerning transportation, installation, and commissioning as well as maintenance, must be

carried out by qualified, skilled personnel, and national regulations for the prevention of accidents must be

observed.

- Before switching the device on, one must check the correctness of all the connections to the network.

- Do not connect the device to the network through an autotransformer.

- The removal of the devices casing during the guarantee contract period may cause its avoidance.

- The equipment fulfils all requirements related to electromagnetic compatibility in the industrial environment.

- When connecting the supply, one must remember that a switch or a circuit-breaker should be installed in the

room. This switch should be located near the equipment, with easy accessibility for the operator, and suitably

marked as an element able of switching the devices’ power off.

- Non-authorized removal of the casing, inappropriate use, incorrect installation or operation, create the risk of

injury to personnel or damage to the device.

6. INSTALLATION

6.1. DEVICE INSTALLATION

Insert the display in the panel and fix it with the four screw clamps according to Figure 1. The panel cut-out should

have 92 x 45 mm.

The overall dimensions of the UD-720 digital display are presented on Figure 2 (in millimeters).

6.2. ELECTRICAL CONNECTIONS

The display has two separable terminal strips with screw terminals. The strips enable the connection of wires with a

cross-section of 1.5 mm2for input signals and 2.5 mm2for other signals.

6.3. INSTALLATION RECOMMENDATIONS

In order to obtain a full protection against electromagnetic noise, it is recommended to follow the principles below:

Do not supply energy to the device from the network in the proximity of equipments generating high pulse

noises.

Apply network filters.

Wires leading measuring signals should be twisted in pairs, and for resistance sensors in 3-wire connection,

twisted of wires of the same length, cross-section and resistance, and led in a shield as above.

All shields should be one-side earthed or connected to the protection wire, the nearest possible to the device.

Apply the general principle, that wires leading different signals should be led at the maximal distance between

them (no less than 30 cm), and the crossing of these groups of wires made at right angle (90º).

7. STARTING TO WORK

After turning the supply on, the display carries out the test procedure, showing the program version followed by the

measured value.

7.1. DISPLAY DESCRIPTION

7.2. BUTTON FUNCTIONS

Enter button :

Entry in programming mode, by hold down for 3 seconds.

Moving through the menu (level choice).

Entry in the mode changing the parameter value.

Acceptance of the changed parameter value.

Freezing the measurement (when holding down the button, the display of the input signal is not updated. The

measurement is still carried out).

Up arrow button :

Display of maximal value (the pressure of the button causes the display of the maximal value during 3

seconds).

Entry in the level of parameter group.

Moving through the chosen level.

Change of the chosen parameter value (increasing the value).

Change of digit button :

Display of minimal value (the pressure of the button causes the display of the minimal value during 3 seconds).

Entry in the level of parameter group.

Moving through the chosen level.

Change of the chosen parameter value (shift to the next digit).

Return button :

Entry in the menu monitoring the meter parameters (by holding down the button for 3 seconds).

Exit from the menu monitoring meter parameters.

Escape from the parameter change.

Exit from the programming mode (by holding down the button for 3 seconds).

The pressure of the button combination, for 3 seconds, causes the reset of alarm signaling. This

operation acts only when the support function is switched on.

The pressure of the button combination causes the erasing of the minimal value.

The pressure of the button combination causes the erasing of the maximal value.

The pressure of the button for 3 seconds causes the entry in the programming matrix. The programming

matrix can be protected by the safety code.

The pressure of the button during 3 seconds causes the entry in the menu for monitoring the device

parameters. Move through the monitoring menu by pressing or buttons. In this menu, all the devices’

programmable parameters are only available for readout. In this mode, the menu Ser is not available. To exit from

this menu press the button. In the monitoring menu, parameter symbols are displayed alternately with their

values.

8.1. PROGRAMMING

By pressing and holding down the button during 3 seconds one can enter the programming matrix. The

programming matrix can be protected by an access code. If the entry is protected by a password, then the safety

code symbol SEC is displayed alternately with the set value 0. The insertion of the correct code causes the entry in

the matrix, and the insertion of an incorrect code causes the display of the ErCod symbol.

Figure 6 presents the transition matrix in the programming mode. The choice of the level is made by means of the

button, however the entry and cycling through the parameters of the current level is carried out by means of

the and button. Parameter symbols are displayed alternately with their current values. In order to

change the value of the current parameter, use the button. To escape from the change, use the button.

In order to exit from the chosen level, chose the ----- symbol and press the button. To exit from the

programming matrix, press the button during 1 second. Then, the symbol End appears for 3 seconds and the

meter transits to displaying the measured value. If the device is left in programming mode it will return to the normal

working mode automatically 30 seconds after the last pressure of any button.

In order to increase the values of the selected parameter press the button. A single pressure of the button

causes the increase of the value by 1. The To change to the following digit press . In order to accept the set

parameter, hold down the button.

8.3. CHANGING FLOATING-POINT VALUES

The change is carried out in two stages (the transition to the next stage follows after pressing ):

1) Setting the value from the range -19999M...99999, similarly as for integral values.

2) Setting the decimal point position (00000., 0000.0, 000.00, 00.000, 0.0000). shifts the decimal point to the

left and shifts the decimal point to the right.

The pressure of the button during the change of the parameter value will cause the cancelation of the

process.
