1.3 Use according to the intended purpose

This digital display may only be operated as a built-in device. The application area for this display device lies in industrial processes and controls, in the fields of manufacturing lines for the metal, wood, plastics, paper, glass, textile and other like industries. Over-voltages at the terminals of the device must be kept within the limits of Over-voltage Category II. If the digital display is used to monitor machines or pro- cesses in which, in the event of a failure of the display or an error made by the operator, there might be the risk of damaging the machine or causing an accident to the operators, it is your responsibility to take the appropriate safety measures.

• Display range from -19999 to 99 999 with leading zero blanking and programmable decimal point

• The functions and operating parameters are programmed by means of the two setting keys. Operator guidance on the display during the programming routine

Latch/Reset (Terminal 4) Static input for display storage. If it is activated (pnp) with a 4…30 V DC input signal, the cur- rent measuring value is retained on the display until this input is released or its signal level sinks below 2 V DC. The determination of the minimum and maximum value continues in the background. If an electrical reset is program- med for MIN, MAX, or for the Totalizer functi- on, the function of the input changes to that of a reset input. It is therefore no longer possible to perform a Latch. Current input (Terminal 5) Analog current measurement input with rever- se polarity protection and current limitation to 50 mA. The signal line carrying the analog + signal must be connected here. To prevent interference signals due to the power supply, this input is galvanically isolated. Therefore, the most negative signal line must be connected to the analog reference ground input for measurement. Analog GND (Terminal 6) Analog reference input. If no galvanic separation is required between the measuring circuit and the supply voltage, pin 2 or 3 must be connected to this terminal. Voltage input (Terminal 7) Analog voltage measurement input. The signal line carrying the analog + signal must be connected here. In case of reverse polarity, this input is protected by a diode. To prevent interference signals due to the power supply, this input is galvanically isolated. Therefore, the most negative signal line must be connected to the analog reference ground input for measurement.

reset of the minimum, maximum values and of the totalizer Pressing the right key allows switching between the display of the current measured value, the minimum and maximum value and the totalizer value, provided these have been activated during programming. Press once to display the current function ("Act", "Min", "Max" or "totAL") for 2 seconds. If the right key is pressed once more during this period, the current function changes and "Act", "Min", "Max" or "totAL" is displayed for about 2 seconds for confirmation. Then, the value is displayed. If "Min", "Max" or "totAL" is selected, this value can be erased by pressing the left red key, provided the reset has been enabled in the programming menu. If neither the maximum or minimum value storage nor the totalizer function has been activated in the setup, the keys have no function during operation.

3.2 Setting the device parameters

a. Keep both front side keys depressed and switch the supply on, or, if the power sup- ply is on, press both keys simultaneously for 5 seconds b. The following message is displayed c. As soon as the keys are released, the fol- lowing message is displayed c1. To abort the programming cycle, keep the left key depressed and press the right key. c2. Press the right key to switch to d. To switch to the first parameter, keep the left key depressed and press the right key e. As soon as the key is released, the dis- play alternates every second between the menu title and the current menu item setting. If a key is pressed, only the menu item setting remains displayed. f. Press the right key to change the menu item setting by one value every time. If numerical values are to be input (e.g. to set the factor), select the decade with the

A value to be displayed bet- ween -19999 and 99999 can be assigned to the lowest input signal (0V, 2V, 0mA, 4mA). The decimal point set- ting is taken into considera- tion (e.g. range 0…10V, this programmed value is issued for 0V). This menu item allows exten- ding or reducing the measu- ring range. If the input signal becomes lower than the value programmed here for the measuring range 4…20 mA, min. 3.5 mA, default 4 mA 0…20 mA, min. -0.5 mA, default 0 mA 2…10 V, min. 1.5 V, default 2 V 0…10 V, min. -0.5 V, default 0 V is displayed, the display alternates between „Lo“ and the measured value. Below the min. programmable measuring value, -1.9.9.9.9 is displayed to signal an underflow. left key and then set the value with the right key. g. To switch to the next menu item, keep the left key depressed and press the right key h. Selecting "Yes" in the last menu title ”End- Pro” allows exiting the programming menu and taking over (saving) the new values. If "No" is selected, the programming routine restarts from the beginning; the last values set are maintained. They can now be modified once more or checked.

4. Programming routine

The settable parameters of the device are listed below, in the order in which they will be set. Thus, the device is entirely set after com- pletion of the routine. The top symbol always corresponds to the factory setting.

4.4 Minimum input signalenglish

Page 4 (R60046.0009 - Index 1) The highest input signal (10V, 20mA) can be assi- gned a displayed value bet- ween -19999 and 99999. The decimal point setting is taken into consideration (e.g. range 0…10V, this programmed value is issued for 10V).

4.8 Minimum value display

Minimum value is displayed The minimum value display is ignored and the next menu title is skipped

4.9 Minimum value reset

Acquisition only within the measuring range set under 4.1, 4.4

4.7 Display value for the highest input

signal Manual reset (with red key) and electrical reset. When activated, the RESET input and the RESET key reset the minimum value to the current measured value. No reset of the minimum value possible. Electrical reset only. When activated, the RESET input resets the minimum value to the current measu- red value. Manual reset only. When activated, the RESET key resets the minimum value to the current measured value. If the input signal exceeds the value program- med here for the measuring range 4…20 mA, max. 20.5 mA, default 20 mA 0…20 mA, max. 20.5 mA, default 20 mA 2…10 V, max. 10.5 V, default 10 V 0…10 V, max. 10.5 V, default 10 V is displayed, the display alternates between „Hi“ and the measured value. Above the max. programmable measuring range, 9.9.9.9.9 is displayed to signal an over- flow. In case of an input voltage >10.8V there is an error, the message Error4 is displayed. This menu item allows exten- ding or reducing the measu- ring range.

Maximum value is displayed The maximum value display is ignored and the next menu title is skipped Acquisition only within the measuring range set under 4.1, 4.6

4.11 Maximum value reset

Manual reset (with red key) and electrical reset. When activated, the RESET input and the RESET key reset the maximum value to the cur- rent measured value. No reset of the maximum value possible.Page 5 (R60046.0009 - Index 1) Electrical reset only. When activated, the RESET input resets the maximum value to the current measu- red value. Manual reset only. When activated, the RESET key resets the maximum value to the current measured value.

4.12 Total sum counter (totalizer)

Measured value totalizing switched off Measured value totalizing switched on In case of counter over or underflow (>99999 or <-19999), the display flashes every second. In case of values >99999, the counter goes on counting and looses no value until reaching the internal counter value 199999. When the internal counter value 199999 is reached, no more values are added. The display goes on flashing every second, but the value remains 99999. In the negative direction, when it reaches <-19999, the value stops immediately and flashes every second. No leading zero blanking in case of overflow. The totalizer adds the cur- rent measured value every second. Totalizing only takes place within the set measu- ring range (4.1, 4.4, 4.6)

4.13 Totalizer decimal point setting

As for the current measured value, the decimal point for the display can also be pro- grammed for the sum (totalizer value). This has no effect on the display accuracy (only for display purposes). However, the expected maximum sum must be taken into conside- ration. If, as in example 8.5, the expected sum is 1000, one decimal place should be set at the maximum. Factory setting Sufficiently digits should be reser- ved for the display of the expected sum, as the sum stops at 199999 and the measuring result thus gets lost. If the 5-digit display is not suf- ficient, the "Factor" (4.14) and the "Scaler" (4.15) allow adjusting the sum accordingly.

Select the decade with the left key and set a factor bet- ween 0.0001 and 9.9999 with the right key.

The displayed totalizer value can be adapted optimally for the measuring task thanks to the factor. If for example the current measured value must be displayed in small units such as grams, but the result of the sum must be displayed in kilograms or tons, input the corre- sponding factor (multiplier): Note: Factor and scaling only affect the totalizer. Total scaling = Factor x Scaling!english Page 6 (R60046.0009 - Index 1)

Scaling allows extending the display range for the totalizer or reducing it for a very fine setting. Select the required scale with the right key: 1 (factory setting), 0.1, 0.01, 0.001 or

In example 8.6 on page 9 the tank can contain more than 100,000 l. Scaling 0.01 allows displaying the sum in hectoliters. As the scaler (= multiplier) only affects the sum, the current flow rate is still displayed in liters/second. Note: Factor and scaling only affect the totalizer. Total scaling = Factor x Scaling! Electrical reset only. The reset key is disabled. The Latch/Reset input operates as a RESET input. When actuated, it sets the totalizer to 0. Manual reset only. The Latch/Reset input operates as a LATCH input. The current value displayed is frozen.

4.16 Totalizer reset

There are four possibilities to reset the tota- lizer. This setting affects the function of the Latch/Reset input.

4.17 End of programming

The programming routine is performed once more. The value set until now can be checked and modified. The programming routine ends and all set values are taken over as new para- meters. The device is then ready for operation.

5. Terminal assignment

Manual reset (with red key) and electrical reset. The MPI input operates as a RESET input. When actuated, it sets the totalizer to 0. No reset possible. The Latch/Reset input ope- rates as a LATCH input. The current value displayed is frozen.Page 7 (R60046.0009 - Index 1)

8.1 Temperature measurement

A temperature sensor with linear characte- ristics (in case of non-linear sensors, install linearizing components upstream) delivers 0 V at -10°C and 10 V at 80°C. The selected mea- suring range is 0…10 V. 0 V is the smallest measured value possible. The display value -10 is now assigned to this measured value. Accordingly, 10 V is the largest measured value. The display value 80 is assigned to this measured value. The display is now set for the sensor and can display any intermediate value. Display value freely positionable within the measuring rangeenglish Page 8 (R60046.0009 - Index 1)

8.2 Filling level measurement

A filling level sensor with linear characteristics (in case of non-linear sensors, install linea- rizing components upstream) delivers 4 mA when a container is empty and 20 mA when it is full. The value 10 m

must be displayed for the full container and 0 m

for the empty cont- ainer. The selected measuring range is 4…20 mA. 4 mA is the smallest measured value possible. The display value 0 can now be assigned to this measured value. Accor- dingly, 20 mA is the largest measured value. The display value 10 is assigned to this mea- sured value. The display is now set for the sensor and can display any intermediate value.

8.3 Removed quantity

Instead of the filling quantity, the value to display is the removed quantity. The selected measuring range is again 4…20 mA. A display value of 10 is now assigned to the smallest measured value (4 mA) and a display value of 0 is assigned to the largest measured value (20 mA).

8.4 Filling level measurement with limit

value display In this third case too, the available quantity must be displayed ; the container has a capacity of 10 m

but it can be filled at the maximum to 8 m

. Moreover, the content shall not sink below 1 m

„Lo“ must be displayed. The selected measuring range is 4…20 mA. The display value 0 is assigned to the smallest input value and 10 is assigned to the largest input value. In addition, the menu item "Mini- mum input signal" is used to set the measured value that corresponds to a content of 1 m

, e.g. 5.6 mA and the menu item "Maxi- mum input signal" is used to set the measured value that corresponds to a content of 8 m

8.5 Weight measurement with totalizing

The quantity of granulate is to be determined by means of flow measurement. At full flow rate (= 10 kg/sec.), the measuring sensor delivers 20 mA The selected measuring range is 0…20 mA. Assign the value 0 to the lowest input signal and 10 to the highest. To display the sum in tons, set a factor of 0.001. The decimal point is only for display purposes. For a current value dis- play of 10.0, the totalizer would add every time 100. This must be taken into considera- tion accordingly when setting the factor. If the current flow rate is to be dis- played with one decimal place, set the factor to 0.0001.

8.6 Flow measurement with totalizing

The flowing quantity and the totalized quantity are to be displayed alternately. The measuring sensor with linear characteristics (in case of non-linear sensors, install linearizing components upstream) delivers 4 mA when stopped and 20 mA at full flow speed, which corresponds in this example to 90 l/minute. Select with "range“ the measuring area 4…20 mA and, for the minimum and maximum input signal "lo.act" and "hi.act", the respective factory setting. Assign the display value 0 to the lowest input signal "lo.display" and assign the value 1.5 (corresponding to l/second) to the highest input signal "hi.display". Set the decimal point for the totalizer "dp.tot" according to the expected maximum quantity: for the maximum volume of a 100,000 l bottling plant, select zero decimal place for the totalizer and, as this still is not sufficient, use "scaler"
