1. Safety Instructions and Responsibility 1.1. General Safety Instructions This operation manual is a significant component of the unit and includes important rules and hints about the installation, function and usage.
1.3. Installation The device is only allowed to be installed and operated within the permissible temperature range. Please ensure an adequate ventilation and avoid all direct contact between the device and hot or aggressive gases and liquids. Before installation or maintenance, the unit must be disconnected from all voltage-sources. Further it must be ensured that no danger can arise by touching the disconnected voltagesources.
8 Dx34510b_oi_e.doc / Jun-15 0 VAC 0 VAC 115 VAC 0 VAC GND 0 VAC +24VDC OUT PE GND PE TXD / B (-) RXD / A (+) GND INPUT A GND Units with option SV006 provide 24 / 42 VAC power input instead of 115 / 230 VAC 115 VAC RESET (C) DX348: Display unit with serial interface Special versions with TTL inputs (option TTLIN1) provide a +5V aux.
2.1. Power Supply The unit accepts DC supply from 17 V to 30 V when using terminals 1 and 2, and the consumption depends on the level of the supply voltage (typically between 80 mA and 150 mA plus current taken from aux. output). For AC supply, terminals 0 VAC, 115 VAC or 230 VAC can be used. The total AC power consumption is 7.5 VA. Units with option "SV006" are prepared for AC supply with 24 VAC or 42 VAC and the screw terminals are marked correspondingly.
Typical input circuit (standard version with HTL inputs): PNP NPN +24V int. +24V int. 4,7k Input Input 4,7k GND GND GND The counting inputs A and B are designed for input frequencies up to 100 kHz (with all counter modes) and up to 25 kHz (with all other operating modes). The minimum pulse duration on the Reset input must be 500 µsec. (maximum frequency 1 kHz). All inputs are designed to receive impulses from an electronic impulse source.
2.6. Serial RS232 / RS485 interface (DX 348 only) Ex-factory the unit is set to RS232 communication. This setting can be changed to RS485 (2-wire) by means of an internal DIL switch. To access the DIL switch, please remove the screw terminal connectors and the backplane. Then pull the print to the rear to remove the PCB from the housing.
3. How to Operate the Front Keys For setup and other operations the unit uses three front keys which subsequently will be denominated as follows: ENTER (Input) SET (Setting) Cmd (Command) The functions of the keys are depending on the actual operating state of the unit. The following three operating states apply: Normal display state Setup state a.) Basic setup b.) Operational parameter setup Teach operation 3.1.
3.2. Selection and Setting of Parameters 3.2.3. How to select a parameter The ENTER key will scroll through the menu. The SET key allows to select the corresponding item and to change the setting or the numeric value. After this, the selection can be stored by ENTER again, which automatically changes over to the next menu item. 3.2.4. How to change parameter settings With numerical entries, at first the lowest digit will blink.
3.3. Teach Operation The Time-Out Function remains disabled during all Teach operations Key Function ENTER will conclude or abort any Teach operation in progress SET function is fully similar to normal set-up operation Cmd will store the display value to the register and will change over to the next interpolation point. For details of the Teach procedure see section 5.2. 3.4. Set All Registers to “Default“ At any time you can return all settings to the factory default values.
4. The Operator Menu The menu provides one section with “Basic Parameters” and another section with “Operational Parameters”. On the display you will only find those parameters which have been enabled by the basic settings. E.g. when the Linearisation Function has been disabled in the basic set-up, the associated linearization parameters will also not appear in the parameter menu. All parameters, as good as possible, are designated by text fragments.

5. Setup Procedure For better understanding the following sections 4.1 and 4.2 explain settings related to the display only. Model-specific settings for Analog Output, Preselection’s and Serial Link will be explained separately under sections 5.3 to 5.5, later. 5.1. Basic Settings These settings in general have to be carried out one time only upon the very first use of the unit.
Continuation “Basic Settings” Menu Setting Range Default Keypad protection code: (see section 3.5) Keypad enabled continuously Keypad locked for any access Keypad locked, except for access to preselection’s Pres 1 und Pres 2 (DX 347 only) Linearization Mode: *) For details please refer to 5.1 and 5.2 The linearization is switch off. Linearization settings for the positive range only (negative values will appear as a mirror).
5.2. Operational Parameters 5.2.1. RPM, operation as tachometer or frequency counter (Input A = active input, Input B not in use), (only DX346: Input B = active input) Menu Frequency: Set a typical operating frequency for your application. Display Value: Range (OS)* Default 1 Hz to 25 000 Hz 1 ... 99999 1000 1000 Set the value you would like to see on your display with above frequency at the input. Decimal Point: Select the desired position like shown in the display.
5.2.2. Time, display of baking or processing time (reciprocal speed) (Input A = frequency input, Input B not in use) Menu Range (OS)* Default Display Format: Select between seconds, minutes, minutes and seconds or minutes with two decimal positions. This will also automatically set your decimal point to the proper place. Seconds (0) Minutes (1) Minutes and seconds (2) Minutes with two decimal positions (3) Frequency: Set a typical operating frequency for your application.
5.2.3. Timer, Stopwatch Please note that open NPN inputs are always “HIGH“ and open PNP inputs are always “LOW“. Menu Range (OS)* Default Time base / Resolution of the timer: Milliseconds (0) 1/100 seconds (1) 1/10 seconds (2) Integer seconds (3) Minutes with two decimal positions (4) Minutes with one decimal position (5) Hours : minutes : seconds (6) Start/Stop of time measurement: Time count is active while input A is HIGH. (0) Rising edge on input A starts count.
5.2.4. Count, Counter mode Menu Counting Mode: Range (OS)* Input A counts and input B selects the counting direction (LOW = increment, HIGH = decrement) (0) Summing counter, A + B (1) Differential counter, A – B (2) Quadrature up/down counter A/B with single edge count (x1) (3) Quadrature up/down counter A/B with double edge count (x2) (4) Quadrature up/down counter A/B with (x4) edge count. (5) Impulse Scaling Factor: Example: setting 1.
5.2.5. Speed from differential time between a Start and a Stop input Input A operates as a start input and input B operates as a Stop input. The differential time between start and stop will be converted into the speed of the passing object. Menu Time: Enter a typical delay time which you expect between the start and stop signals. Display Value: Enter the speed you would like to see in the display when an object passes within above time. Setting Range Default 000.001 … 999.999 sec 000.001 … 999.999 1.
5.3. Model DX 346: Additional Settings for the Analog Output The Basic Menu provides the following additional settings: Menu Range (OS)** Default Analog Characteristics: Select one of the following options: +/-10 V (bipolar) 0-10 V (positive output only) (0) (1) 4-20 mA current output. (2) 0-20 mA current output (3) Where you set the output to +/-10 Volts, your input signals A/B must be of quadrature type with phase displacement.
The following Operational Parameters provide scaling of the analog output: Menu Analog-Begin: Start value of the analog output. Analog-End: End value of the analog output. Setting Range Default -199999 ... 999999 0 -199999 ... 999999 10000 By means of these two parameters any window of the whole display range can be mapped onto the analog output. The subsequent example shows how to convert the display range from 1400 to 2200 into an analog signal of 2 - 10 volts.
5.4. Model DX 347: Additional settings for Preselection’s The basic setup menu provides the following additional parameters: Menu Range (OS)**** Switching characteristics of output 1. (0) Greater/Equal: output to switch statically ”ON” when display value ≥ preset value. (1) Lower/Equal: output to switch statically ”ON” when display value ≤ preset value. (2) (3) Default Greater/Equal: output to switch dynamically ”ON” when display value ≥ preset value.
The following operational parameters provide setting of the switching points: Menu Setting Range Default -199999... 999999 -199999... 999999 10000 Preselection 1: Preselection 2: 5000 The working direction of the Hysteresis depends on the setting of the switching characteristics.
5.5. Model DX 348: Additional Settings for the Serial Interface The basic setup menu contains the main parameters for configuration of the serial interface Menu Range (OS)* Serial Unit Number: 0 ... 99 Default 11 You can assign any address number between 11 and 99 to your unit. The address must not contain a “0“ because these numbers are reserved for collective addressing. Serial data format: The first character indicates the number of Data Bits.
The following operational parameters provide setting of the communication profile: Menu Serial Timer: Setting 0,000 allows manual activation of a serial data transmission at any time. All other settings specify the cycle time for automatic transmission (provided the Serial Mode is set to "Printer") Range (OS)* Default 0.000; 0.010… 9..999 sec 0.1 sec Between two transmission cycles the unit will allow a pause depending on the baud rate.
5.5.1. PC-Mode Communication with PC - Mode allows free readout of all parameters and registers of the unit. The subsequent example shows the details of communication for serial readout of the actual display value.
Units with serial link also allow setting or resetting the counter by serial command (similar to the external input or front key function). To activate the Reset command, please write “1” to register code “60”. To release the Reset command again, write “0” to the same register. The following strings show how to set or reset a unit with unit No.
5.5.2. Printer-Mode The Printer Mode allows cyclic or manual activation of transmissions of the specified register data. The corresponding register can be specified by means of parameter „S-Code“.
6. Special Functions 6.1. Linearization This function allows converting a non-linear input signal into a linear presentation or vice-versa. There are 16 interpolation points available, which can be freely arranged over the whole measuring range in any distance. Between two points the unit automatically will interpolate straight lines. It is advisable to set many points into areas with strong bending, and to use only a few points in areas with little bending.
Application Example: The picture below shows a Watergate where the opening is picked up by means of an incremental encoder. We would like to display the clearance of the gate "d", but the existing encoder information is proportional to the angular information φ. Display value d = d0 (1-cos φ ) Incremental Encoder d φ Display (d) P16_y P15_y P07_y P05_y Dx34510b_oi_e.
6.2. Manual Input or „Teaching“ of the Interpolation Points Interpolation points to form the linearization curve can be entered one after each other, using the same procedure as for all other numeric parameters. This means you will have to enter all parameters P01_x to P16_x and P01_y to P16_y manually by keypad. During manual input of interpolation points the unit will not examine the settings P01_x to P16_x.
The unit will examine the constraint valid for the x-values of interpolation points. Every interpolation point must be higher than its preceding point. Where this constraint is breached, all 6 decimal points will blink automatically as a warning. Pressing the CMD key will not store the illegal value, but result in an error text "E.r.r.-.L.O." To exit the teach mode again, you have the following two possibilities: 1. Press the enter key for 2 seconds.
