Discription The digital panel meter model UM 3023 is an universal instrument for measuring analog input signals listed below: Voltage 0-10 V Current 0-20 ma / 4-20 ma Standard Hardware 4 function buttons on the frontside Standard Software Scaling Taring Free setting of decimal point Display test 2. Safety instructions When delivered the intrument has been tested to meet all functions described. Before installing the instrument please read the mounting and servicing instructions. We have no liability or responsibility to customer or any other person or entity with respect to any liablity, loss or damage caused or alleged to be caused directly or indirectly by equipment or software sold or furnished by us. Read the installation instruction carefully. No liability will be assumed for any damage caused by improper installation. Inspect the instrument module carton for obvious damage. Be shure there are no shipping and handling damages on the module before processing. Do not apply power to the instrument if it has damages. The warranty does not apply to defects resulting from action of buyer, such as mishandling, improper interfacing, operation outside of design limits, improper repair or unauthorized modifications. 4

Useful hints for better operation. 3. Mounting 3.1. Place of operation Attention must be payed to the protection against humidity, dust and high temperatures at the place of operation Panel mounting Panel for switch board For mounting in switch boards, insert the case into the panel cutout (92,0 +0,8 x 45,0 +0,6 mm) from the front, using a fresh gasket for sealing as required. Click into and place at each side the two fastening clips (M2,5 x 50 mm). Tighten the screws alternately, using enough pressure to get good retention and sealing at the panel. 5

General Instructions It is forbidden to plug or unplug connectors with voltage applied Attach input and output wires to the connectors only without voltages applied Cords must be provided with sleeves Attention must be paid that the power supply voltage applied will agree with voltage noticed at the Type plate. The instrument has no power-on switch, so it will be in operation as soon as the power is connected. 6

8 4. Electrical connections 4.2. Hints against noisy enviroment All inputs and outputs are protected against noisy environment and high voltage spikes. Nevertheless the location should be selected to ensure that no capacitive or inductive interference can have an effect on the instrument or the connection lines. It is advisable: To use shielded cables. The wiring of shields and ground (0V) should be star-shaped. The distance to interference sources should be as long as possible. If necessary, protective screen or metal enclosures must be provided. Coils of relays must be supplied with filters. Parallel wiring of input signals and AC power lines should be avoided Connection and pin assignment All inputs and outputs are connectors designed as plug-in screw terminals

10 5. Start-Up 5. Start-Up Attention must be paid that the power supply voltage applied will agree with the voltage noticed at the type plate. Switch the power supply on (supply voltage applied to 5 (-) and 6 (+)). When delivered, the instrument is programmed with a standard configuration (default configuration). According to his measuring task, the customer can change the standard configuration by programming. Attention: When the instrument is built-in a machine and the customer wants to change the configuration, attention must be paid, that no damage will occur to the machine! 6. Procedure of programming The procedure of programming is organized in different steps and can be carried out via the push buttons on the front of the instrument Function of buttons and LEDs 4-decade display LED 2 LED 1 mm Insertion shield for dimensions Programming button Select the display decade/ Tare Decreasing values Increasing values 9

Programming The operation and the programming of the panel meter is organized in several programming levels. Programming is performed by the buttons on the front. Push button P -button + -button - -button * -button Selection of - parameter Function Increase of - number of parameter - parameter Decrease of - number of parameter - parameter select the display decade in the programming mode / tare button Entering the programming routine Press P -button together with + -button The display shows 0-00" Leaving the programming routine Press + -button or - -button until the display shows 0End Confirm the display 0End by pressing the P -button 10

12 7. Programming Selection of a parameter select the parameter by pressing + -button oder - -button Confirm the parameter by pressing the P -button. The display shows the last programmed value of the selected parameter Change and confirm a selected parameter Change the parameter by pressing the + -button or the - -button Select the display decade to be changed by pressing the * -button Confirm the parameter by pressing the P -button The display shows the programming level and the number of the parameter e.g.: 0-04" => parameter Programming level for configuration 0-00 Param. Description Range 0-00 Input range 0 -> Voltage 0 bis 10 V 1 -> Current 0 bis 20 ma 2 -> Current 4 bis 20 ma Default Value Display value of min. input signal Display value of max. input signal Decimal point 0 -> XXXX 1 -> XXX.X 2 -> XX.XX 3 -> X.XXX Tare on = 1, off = End Leaving programming level

13 7. Programming Scaling the display range Over- and underflows are displayed as follows: An overflow is displayed as nnnn; this occurs if: the input signal exceeds the permissible maximum around more than 0,5V or 1mA; e.g. input voltage >10,5 V or input current >21 ma. the display range exceeds the possible maximum. (> 9999) An underflow is displayed as uuuu; this occurs if: the input signal exceeds the permissible minimum around more than 0,5V or 1mA; e.g. input voltage < -0,5V or input current < -1mA or 3mA. the display range exceeds the possible minimum. (< -999) the parameter P0-03 has the value 3 (decimal point after the first decade: X.XXX) (in this case is the display of negative values is not possible) and the displayed value would be below The display values for the minimum and the maximum input signal is set in the parameters 0-01 and Display value Overflow Parameter 0-02 Example: Input range 0 bis +10 V, Display range: -999 bis Step Param. Value End End -0, ,5 Parameter Input voltage [V] 0-01 Underflow 12

14 7. Programming 7.2. Tare function The tare function works as follows: pushing the tare button will store the displayed value in the tare memory. The tare value will be substracted from the measured value. The tare value is stored in an non-volatile memory and will be saved even when the device is switched off. Activating the tare function: push the * -button (Parameter 0-04 had to be set to 1) Erase the tare value: push the * -button for ca. 3 seconds. After this reset the untared value is displayed Display test Activating the display test will drive all segments of the display. The display shows during the test. Activating the display test push the P -button 7.4.
