1.2 General safety instructions 1. Before carrying out any installation or maintenance work, make sure that the power supply of the digital display is switched off. 2. Only use this digital display in a way according to its intended purpose: If its technical condition is perfect. Adhering to the operating instructions and the general safety instructions. 3. Adhere to country or user specific regulations. 4. The digital display is not intended for use in areas with risks of explosion and in the branches excluded by the standard EN 61010 Part 1. 5. The digital display should only operated if it has been correctly mounted in a panel, in accordance with the chapter “Technical data”. MN05401014E 1:26 PM Page 1 1.3 Use according to the intended purpose The digital display may be used only as a panel- mounted device. Applications of this product may be found in industrial processes and controls, in manufacturing lines for the metal, wood, plastics, paper, glass, textile and other processing industries. Over-voltages at the terminals of the digital display must be kept within the limits in Category II. If the digital display is used to monitor machines or processes in which, in case of a failure of the device or an error made by the operator, there might be risks of damaging the machine or causing accidents to the operators, it is your responsibility to take appropriate safety measures. 2. Inputs INP Dynamic count input. RESET Dynamic RESET input. Linked in parallel to the red RESET key. Sets the counter to zero. 3. Setting of the operating pa ra me ters a. Press both front side keys and switch on the supply voltage or, if the supply voltage is already on, press both keys simultaneously for 5 s. b. The display shows c. After releasing the keys, the display shows 1 italiano deutschfrancaisespanol english (Watermark) MN05401014E:MN05401014E 2/9/07 1:26 PM Page 2 c1. Hold the left key pressed and press the right key to leave the programming operation c2. Press the right key to switch to . d. Hold the left key pressed and press the right key to switch to the first parameter. e. After releasing the keys, the display alternates between the menu title and the current menu item setting. After pressing any key, only the menu item setting is displayed. f. Pressing the right key will switch the menu item setting to the next value. If figures are to be input (e.g. when setting the scaling factor), select first the digit using the left key, and then set the value using the right key. g. Hold the left key pressed and press the right key to switch to the next menu item. h. The last menu title “EndPro” allows the user, when selecting “Yes”, to exit the programming menu and to store the new values. If “no” is selected, the programming routine is repeated, the latest values set remaining active. They can now be checked again or modified. 4. Programming routine The programmable parameters of the device are described below, in succession. The device is fully programmed after one pass of the routine. The first values stated correspond to the factory settings. 4.1 Polarity of the inputs npn: sinking sensor pnp: sourcing sensor 2 4.2 Switching on the 30 Hz filter (INP) The filter provides input damping* 30 Hz filter off (fmax) 30 Hz filter on 4.3 Decimal point setting The decimal point determines the way of displaying the count values. It does not affect counting. 0 no decimal place 0.0 one decimal place 0.00 two decimal places 0.000 three decimal places 4.4 RESET Mode manual reset via the red RESET key and electrical reset via the RESET input no reset (red RESET key and RESET input locked) only electrical reset via the RESET input only manual reset via the red RESET key 4.5 End of programming The programming routine is repeated once more. The values set until now can be checked and modified. The programming routine will be exited and all values set will be stored as new parameters. Afterwards the device is ready for operation. * where bounce occurs, e.g. with contacts MN05401014E (Watermark) MN05401014E:MN05401014E 5.
