The update program is delivered with a text file, called ‘UpdaterReadme.txt’. Also, the standard configuration file ‘Application.cfg’ contains a lot of comment which describes the possibilities of the update set.

  • Page 37: Option Installation

    It is possible to install software options on the control. Options can be requested at Delem. Options for a DA-52s control can be purchased at any moment. It is done by buying an ‘Option Voucher’ for a specific function (e.g. 2nd servo axis). A new option voucher is valid for any DA-52s control.

    Some important directories: \Hard Disk\Delem\Bin This directory contains the Delem control application files. The control application ‘Delem.exe’ is automatically started when the control is activated. Furthermore the Delem sequencer file and the KO-Table are located here. \Hard Disk\Delem\Data Directory with the ‘products’ and ‘tools’ subdirectories, which contain all products and tools for this control.

  • Page 46: Important Files

    A lot of control settings are stored in files, which are located on the hard disk of the control. This is the case for the Delem application as well as for the Windows platform. Whenever the control is (re)started, the software will search for these files and retrieve the last saved settings.

    Common tasks for such a file can be to copy files to or from the flash memory. In the standard file, one task is implemented: activate the Delem application. Other tasks can be added if required.
  • Page 51 Lines in the file that start with ‘REM’ are considered as comment. In the beginning of the file, the ‘if’ instruction checks if the Delem application has a KO-table to work with. If such a KO-table is present, the subsequent instruction is skipped.

The text file with sequencer code is stored on the hard disk of the control, in the file seq_inp.txt. This file can be edited with the application Notepad that is built-in on the control. An alternative could be to copy the file to a USB disk and edit the file from a PC.

    Upon start-up, the program will first prompt for an access code: Figure 2.m Here you must enter a ‘level 2’ code, which is also used to modify all Delem machine parameters in the DA application. The default access code here is 32157.

The program will show the following dialog: Figure 2.n This means the analysis tool is now waiting for a bend cycle to be executed. Now switch to the DA application and execute a bend cycle in the normal way. The analysis program actually starts recording when a fast closing or a pressing command is activated.

  • Page 62: Part Iii - The Diagnostic Program

    Delem Part III - The diagnostic program To be able to test a DA-52s control, it has been equipped with a diagnostic program. With the test functions of the diagnostic program the service engineer can test the control itself and the communications to externally connected system components.

  • Page 63: General Remarks

    In the description of the tests it is indicated which component(s) is(are) responsible for correct functioning of that particular part. See for exploded view drawing with all internal cables and cards of the DA-52s controls the included diagrams at the end of part I.

  • Page 64: Test-Menu

    To end the diagnostic program the power supply to the control can be switched off and then on again to enter the normal operation menu. It is also possible to leave the diagnostic program with the ‘END’-key. The Delem application will restart.

Analog and digital outputs can be set high and low with keys on the front panel. The read-out of analog inputs and the encoders is continuously. When a reference pulse of the linear scales is received in the electronics, the corresponding measured value will shortly be highlighted in inverse colour.

  • Page 70: Testing The Valve Deflection

    The test procedure for valve deflection depends on the type of valves that is installed. On the following two pages two different procedures are described. The first procedure is for Hoerbiger valves, which are connected directly to the DA-52s. The second procedure must be followed when external valve amplifiers are used to control the valves.
