FRONT PANEL DESCRIPTION

1. Key-pad: functions available outside the programming phase. Key to be pressed: Displaying of set-point; Displaying of maximum measured value (peak feature); For longer than 5 seconds: reset of the maximum measured value (the display will be blinking); For longer than 5 seconds: reset of activated set-point (only for set-point with latch). 1. Key-pad: functions available in the programming phase. Key to be pressed: For longer than 2 seconds: programming phase entry and password confirmation;
Menu selection (from the first to the last); Menu selection (from the last to the first);
Confirmation and entry: in the configuration menus; in the secondary menus relating to parameters. In the selected menu / secondary menu: increase of displayed value modification of parameter selection; In the selected menu/secondary menu: decrease of displayed value modification of parameter selection.
2. Display Alphanumeric indication by means of 7-segment LEDs: of the measured value; of the programming parameters; of the measuring abnormal conditions. 3. Engineering unit window To insert the interchangeable engineering unit in the special window, proceed as follows: remove the front cover by inserting a suitable screw driver in the special slot on the short sides of the front panel; force gently until the front cover is completely removed. Insert the desired engineering unit by means of a pair of tweezers. Replace

the front cover by inserting it first in the lower part and then in the upper part of the locking system. OPERATING MODE Power-on When you switch the unit on, the instrument shows for approximately 5 seconds the instrumentss software revision, for example: r.1. Displaying, control (if present) and diagnostics The instrument shows continuously the value of the input variable as defined in the programming phase. The value shown on the display is continuously compared with the value of the set-point and of the other parameters, thus generating the control function by energizing/de-energizing the output relay. Programming This phase is identified by the blinking of the decimal point on the right side of the display. To enter the programming phase, press the S key until PAS is shown on the display; then 0 is displayed: the correct numerical code (password) is to be entered. The following conditions may occur: 1) the operator hasnt entered any Password: press the S key again to enter the configuration menus of the instrument;
2) the operator has already entered a Password: select the correct password by means of the key (to increase the value) or key (to decrease it) until the desired value is displayed. Press the S key to confirm the value: if the password is correct, then the display will show PAS again followed by the relating numerical code; press the S key once more in order to display the first configuration menu; if the password is not correct, the display shows End and the instrument goes back to the measuring and control phase. PROGRAMMING OF A NEW PASSWORD AND AUTOMATIC SELECTION OF THE PROTECTION LEVEL OF THE CONFIGURATION DATA. To enter the new Password: if the Password is 0, press the S key when the display shows the PAS message for the second time; enter the desired numerical code using the or keys, then confirm it by pressing the S key: the display will show the first configuration menu (inP); if the Password has already been entered, you can modify it following the procedure described at No. 2; after the PAS message has been shown a second time, enter the new numerical code using the or keys and confirm it by pressing the S key: the display will show the first configuration menu (inP). Data protection levels: if the password is 0, the configuration data are not protected by undesired accesses;
if the Password is a number between 1 and 255, the configuration data are entirely protected against undesired accesses; It is possible to reset the Password by entering the number 768. All programming/configuration steps of LDI35 are shown in the flow chart in the centre of this manual. The flow chart has been conceived to make the operator better understand the programming structure of LDI35 indicating the position of the current function with regards to the others. The flow chart also makes more easily understandable the commands to be used in the configuration phase. See the chapter Front panel description for information regarding the use of the key-pad and the relevant main functions. Glossary of displayed symbol: (the symbols like PAS in a black background belong to the main menu; the symbols like AC in a white background belong to the secondary menu). PAS : access key to programming inP : menu to select measuring inputs For LDI35.AV2 only: AC : AC voltage/current measurements; dC : DC voltage/current measurements. For LDI35.CF only: rtd : thermoresistance/Ohm measurements; tC : thermocouple measurements r1 , r2 , r3 , r4 , r5 : range selection (see table inP in the flow chart). SCA : menu to program the scaling parameters

Lo.E : programming of the min. value of the electrical scale (see table inP in the flow chart). Enter the minimum value that is to be measured (zero scale). Hi.E : programming of the max. value of the electrical scale (see table inP in the flow chart). Enter the maximum value to be measured (full scale). NOTE: in the resistance measurements (inP rtd r5) the maximum electrical full scale to be entered is: 1999 and the corresponding value of Hi must be 199.9 in order to take resistance measurements with a 0.1 resolution. NOTE: if the measured variable goes beyond the scale limits Lo.E/ Hi.E, the value displayed during the measuring phase will be blinking and updated with reference to the measured value up to the maximum displaying range (dC and temperature measurements: -1999/1999; AC and resistance measurements: 0/1999). d.P : selection of the decimal point position in the Hi-Lo scale. Lo : programming of the min. value of the displayed scale. Enter the value to be displayed in correspondence with the minimum value of the electrical scale Lo.E. Example: Lo.E=4.00 mA Lo=100 mbar, means that when the value measured by LDI35 is 4 mA, the displayed value will be 100 mbar. Hi : programming of the max. value of the displayed scale. Enter the value to be measured in correspondence with the maximum value of the electrical scale Hi.E. Example: Hi.E=19.99 mA Hi=1800 mbar, means that when the value measured by LDI35 is 20 mA, the displayed value will be 1800 mbar. NOTE: electrical scale and displayed scale must have:
corresponding values (Lo.E = Lo, Hi.E = Hi), if the same value is to be both measured and displayed. different values, if the signal to be measured is different from the one to be displayed (see examples of Lo and Hi). inverted values, if an increasing signal to be measured must correspond to a decreasing value to be displayed (scale inversion). Example: Lo.E=4.00 mA Lo=1800 mbar; Hi.E=19.99 mA Hi=0 mbar, means that when the measured value increases from 4 to 20mA, the displayed value decreases from 1800 mbar to 0. As you can see, the scales can be programmed with absolute freedom. NOTE: to display temperature values as F, it is necessary to program the electrical scale as C and enter the values for the displayed scale according to the following relationship: F = (1.8 x C) + 32. Example: Lo.E=-50 C Lo=-58 F; Hi.E=+760 C Hi=+1400 F, means that the new measuring range becomes -58 F to +1400 F. The data to be entered in the displayed scale can be calculated either by means of the above mentioned F relationship, or using the data of the relevant measuring range (see chapter Technical Features, paragraph Inputs (temperature). diS : menu to select the displaying mode. 35 : displaying at 3 1/2 digit (1999) 30 : displaying at 3 digit + dummy zero (9990). SP.1 : menu to select the programming of the set-point parameters. tYP : selection of the type of control. oFF : signalling of the abnormal condition. The relay is activated when a burn-out condition occurs or the measurement is out of the electrical

range (displaying and blinking of the measured value or displaying of the EEE/ -EE message). Note: by selecting this function the SE.t, HYS parameters are not active. do : down/low alarm set-point. The relay will be activated when the measured value goes below the set-point value. uP : up/high alarm set-point. The relay will be activated when the measured value goes over the set-point value. d.do : alarm set-point similar to do, but with alarm inhibition eventually present when LDI35 is switched on. The control starts only after the first condition of non-alarm has been signalled. uP.L : up/high alarm set-point with latch function. The alarm functions as per uP, but the alarm can be reset only manually when the key is pressed for at least 5 seconds during the measuring phase. do.L : down/low alarm set-point with latch function. The alarm functions key is pressed as per do and can be reset only manually when the for at least 5 seconds during the measuring phase. SEt : value of the alarm set-point to be programmed within the following range: Lo. SEt Hi. HYS : programming of the hysteresis value of the set-point. The hysteresis is a numerical value included within the range: 0 HYS 1999/9990 and represents the difference between the value of the ON alarm status and the value of the OFF alarm status. The hysteresis modifies the value of the OFF alarm status not only with regards to the
set alarm value, but also with regards to the alarm type: the hysteresis value is summed to the set value if the alarm type is do and subtracted from the set value if the alarm type is uP. Example: do alarm, SEt=220 (value of the ON alarm status), hysteresis HYS=12 resulting OFF value (end of alarm status): 232 (resulting from 220 +12). uP alarm, SEt=220 (value of the ON alarm status), hysteresis HYS=12 resulting OFF value (end of alarm status): 208 (resulting from 220 - 12). NOTE: the hysteresis is to be programmed according to the displayed range. oF.d : programming of the value, expressed in seconds, of the time delay at the alarm set-points deactivation (OFF). Value to be programmed within the range:0 oF.d 255. This delay can be useful when it is necessary to guarantee the alarm output activation for a sufficiently long time which is to be acquired by the processing system connected downstream LDI35. on.d : programming of the value, expressed in seconds, of the time delay at the alarm set-points activation (ON). This value is to be programmed within the range: 0 on.d 255. This value can be useful when it is necessary to avoid the alarm set-points activation if the alarm duration is not long enough. Example: when the pressure of a liquid to be measured decreases very quickly because of air bubbles, but this is not a danger for the monitored plant. rLY : selection of the normal status of the relay coil. nd : normally de-energized coil.
nE : normally energized coil. FiL : menu to program the digital filters parameters. This function allows you to solve two different kinds of problems: stabilize the value of the instantaneous measurement displayed by LDI35 when the value is not enough stable from the beginning and would not therefore allow either a clear reading on the display or a good control by the alarm set-point (if present); allow an amplitude of the displayed scale as regards to the electrical one >2. An example of how the electrical scale is to be used can be the measurement of a process signal from a transmitter: 0 to 20mA, 4 to 20mA, 0 to 10V, 0 to 5V, 1 to 5V and so on, which can correspond to a pressure, humidity, temperature, etc. In this case the measured signal managed by the electrical scale (see Lo.E, Hi.E) has a numerical value which is completely different from the one of the displayed scale (see Lo, Hi). Fi.S : programming of the activation range of the digital filter. This value is programmable within the range: 0 Fi.S 1999/9990. The programmable numerical value represents the fluctuation range of the value which has been measured and displayed by LDI35. In the first configuration phase this value must be 0 and the right value is to be entered only after the verification of the possible fluctuation. Example: the measured instantaneous value varies from 1204 to 1210, and the value to be entered as Fi.S is 6 (1210 - 1204). Fi.C : programming of the value of the filtering coefficient. Value to be programmed within the range: 1 Fi.C 255. The higher Fi.C, the higher the filtering of the measured value and the

longer the updating time of the displayed value and the alarm set-point. NOTE: for a correct working of the filter, the relative coefficient must satisfy the following relationship: 1 Fi.C (Fi.S x 8) 255. Example: in order to display a temperature with a resolution of 0.1 C, set Lo.E=-20 C Lo=-20.0 C, Hi.E=200 C Hi=199.9 C. In this case the scale ratio will be 10 times with a clear fluctuation of the value displayed in the measuring phase. In order to stabilize the value it is necessary to enter the parameters Fi.S and Fi.C. The value fluctuates of 0.5C max., therefore Fi.S=0.5 and the filtering coefficient is to be entered making various attempts starting from a minimum value, for example Fi.C=3. The datum will not remain stable, therefore Fi.C is to be increased; in our case the optimum value is Fi.C=15. End : Selection of the exit from the programming phase. Diagnostic messages EEE blinking indication: burn-out up or overcoming of the displaying range (value to be displayed > 1999/9990). -EE blinking indication: burn-out down or overcoming of the displaying range > -1999/1990). 3 or 4 blinking points indicate the set-point activation.
