  • Page 4: Introduction

    Process controllers of series AX345 to AX347 have been designed for this kind of requirements. Model AX 345 provides display function only. Model AX 346 provides additional analogue outputs instead of the Preselections Model AX347 provides two additional programmable Preselections with Optocoupler outputs All other functions within this controller family are fully similar.
  • Page 5: Terminal Assignments

    2. Terminal Assignments 1 2 3 4 5 6 7 8 9 10 The connection of PE is optional and not necessary for safety or for EMC. However, with some applications, it can be useful to ground the common potential of all signal lines •...
  • Page 6: Power Supply

    Power supply 2.1. The unit accepts DC supply from 17V to 30V when using terminals 1 and 2, and the consumption depends on the level of the supply voltage (typical 80 mA at 30V or 130mA at 17V, plus current taken from the aux. output). For AC supply, terminals 0 VAC and 115 VAC or 230 VAC can be used.
  • Page 7: Jumper Settings

    3. Jumper Settings When your input signal is a current of 0-20 mA or 4-20 mA, there is no need to change jumper settings and you can skip this section. Where, however, you intend to use one or both inputs for voltage signals, you must change the internal jumper settings correspondingly.
  • Page 8 Input A = current, input B = voltage Input A = voltage, input B = voltage After setting the jumpers, please shift the print carefully back to the housing, in order not to damage the front pins for connection to the keypad plate. Current inputs are automatically scaled to an input range of 0/4 –...
  • Page 9: How To Operate The Keys

    4. How to Operate the Keys The unit uses 3 front keys for all setup operations. Subsequently, the key functions will be named as shown in the table below. ENTER (Command) The functions of the keys are depending on the actual operating state of the unit. The following three operating states apply: •...
  • Page 10: Parameter Settings

    Parameter settings 4.2. 4.2.1. 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.
  • Page 11: Teach Operation

    Teach operation 4.3. The Time-out function will be switched off during all Teach operations 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.
  • Page 12: The Parameter Menu

    5. The Parameter 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 Linearization Functions have been disabled in the basic set-up, the associated linearization parameters will also not appear in the parameter menu.
  • Page 13: Setup Procedure

    6. Setup Procedure Basic Parameters 6.1. In general, the parameters described subsequently must be set with the very first commissioning of the unit only. Menu Text Default Mode of operation Single input operation (input A only) Dual input operation (input A and input B separately) Sum operation (input A + input B) Differential operation (input A –...

  • Page 15: Operational Parameters

    Operational parameters 6.2. After the basic setup, you can access the operational parameters by pressing ENTER for at least 3 seconds. You will only find those parameter texts that are relevant for your mode of operation. The parameters for scaling of the analogue output will appear at the end of each menu. Since they are absolutely the same with all operating modes, these parameters will be described separately in section 6.4.4.

Single mode (input A only) Menu Text Setting Range Default Input A range Set the desired range for input A Voltage +/-10V Current 0-20 mA Current 4-20 mA Start value -99999 … 99999 Value which the unit will display with a zero input signal of 0 volts or 0/4 mA End value -99999 …...
  • Page 17: Dual Mode (Inputs A And B Separately)

    6.4.2. Dual Mode (Inputs A and B separately) With this mode, the SET key selects between display of channel A and display of channel B, and the bar of the high order LED indicates which of the two channels is actually in display. Menu Text Input Range Default...
  • Page 18: Combined Modes (A+B, A-B, A:b, A•B)

    6.4.3. Combined Modes (A+B, A-B, A:B, A•B) These modes allow displaying either the single channels A and B or the calculated result according to the selected combination. The SET key allows scrolling between the three displays. The upper bar of the high order digit indicates that you display channel A.
  • Page 19: Parameters For Scaling Of The Analogue Output

    6.4.4. Parameters for scaling of the analogue output The analogue output operates at any time under control of the display value and the scaling parameters explained below. This means that the analogue signal also will contain the same calculations, combinations and linearization as shown in display. Output swing and zero definition have already been set with the basic parameters under 6.1.

  • Page 21: Special Functions

    8. Special Functions Tare / Offset function 8.1. This function will become active after the “Cmd” parameter has been set to “oFFSEt” or to “both”(see 6.1). As a result, every touch of the “Cmd” key will store the actual display value to the Offset register, resulting in a Zero display with the actual input signal.

  • Page 23: Manual Input Or „Teaching" Of The Interpolation Points

    Manual input or „Teaching“ of the interpolation points 8.3. Interpolation points to form the linearization curve can be entered one after another, using the same procedure as for all other numeric parameters. This means you will 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.
  • Page 24: Update Time Of The Display And The Analogue Output

    • Press once more “Cmd” to display the actual analogue input signal. Now arrange for the desired analogue input signal of the first interpolation point (with combined modes please arrange for both analogue signals) • When you read the x-value of your first interpolation point in the display, press “Cmd” again.
