  • [GT-250-PE OPERATION] April 22, 2014 3 Human-Machine Interface The interface consists of 3 areas: overhead menu, central display for values and the bottom area for Status display and utility buttons. The main screen of the GT-250-PE Software consists of 3 Graph Bars, displaying the 3 measured and calculated values: Force, Bend and Speed, each displayed with 2 decimals their respective measuring units. These are used to display the Real Time value of the measurements. The sample rate of recording is 200 Hz, however for practical reasons the displayed value is only refreshed at a 10Hz rate, making the values shown readable. To the right of the graph bars there is a real time display of the end graphic which has an update rate of 5Hz, however the actual values are recorded at the 200Hz rate.
  • [GT-250-PE OPERATION] April 22, 2014 4 Above the real time graphic display, the user type, date and time are displayed. The Status area displays the current state of the machine, and has the following possible states: IDLE, Hydraulic Check, Prepare for Bending, Ready to Bend, Bend in Progress. Each will be discussed individually later on. The Slow Bend Test Setup displays the current setup and information about the rail about to be tested as the Operator has configured it. To the right of the "Slow Bend Test Setup" there are 2 buttons and 1 usb status display. The "print last report" button offers the Operator the ability to generate the PDF for the previous bend process. The process will be detailed later on. The "refresh graph" button refreshes the Real Time graph of the interface and should only be used for consecutive Bend Tests during the same session. If this is not used the result will be a comparative graph display of all the tests performed until this button is hit. This function is not available during the bend test. The" USB Ready" status is used to display the presence of a USB Mass storage device. The overhead menu contains 5 buttons: "Home", "Configure", "Bend History", "Log Off" and "Close". These can be accessed through-out the entire operation of the interface with a few exceptions that will be detailed later on. To return to the Main Screen you can always press the "Home" button.
  • [GT-250-PE OPERATION] April 22, 2014 5 Configuration Panel The configuration panel consists of 4 sub-menus that define both test and report parameters. All sub-menus have 3 buttons: "Set" , "Clear" and "Close". The "Set" button validates the changes made to the inserted parameters and returns the operator to the previous screen. The "Clear" button resets all parameters and leaves a blank space. The "Close" button returns the operator to the previous screen. The "Operator Details" sub-menu contains the Press Operator details that will be displayed on the final report. "Operator ID" is an exception as it is only used internally for database purposes. To complete each field press the keyboard symbol displayed in the sub-menu window, this will bring up the On-Screen Keyboard. Press (Enter) after each field is complete. As seen in the above image the Operator Details contains 4 fields: - First Name (Reported) - Last Name (Reported) - Job Title (Reported) - Operator ID (Not Reported)
  • [GT-250-PE OPERATION] April 22, 2014 6 The "Location Details" sub-menu contains the fields to be completed for the location details that will be displayed on the final Report. The "Country" field can be completed with either the country initials or the full name of the country. The "Bend Location" field represents the location of the press when the test is performed. These are important details as environmental parameters can affect both rail and slow bend test results.
  • [GT-250-PE OPERATION] April 22, 2014 7 The "Bending Setup" sub-menu contains the slow bend test parameters to be followed for the next test or until the parameters are changed. The "Required Force" field defines the minimum force to be reached for the rail coupon to pass as valid; the value entered here can be anywhere between 0 and 2500, value expressed in KN. The "Required Bending" field defines the minimum bending to be reached for the rail coupon to pass as valid; the value entered here can be anywhere between 0 and 50, value expressed in mm. The "Break Rail?" option defines if the test should continue until rail break, after the minimum requirements have been met. If this option is not selected the test will go on until the minimum value of each measurement + 1.5% are exceeded, and if the rail doesn't break the test will be evaluated as Passed. If the option is selected the test will continue until the rail breaks and evaluated according to the minimum requirements.
  • [GT-250-PE OPERATION] April 22, 2014 8 The "Welding Details" sub-menu is used to enter data regarding the welded rail coupon to be tested. As seen in the image above, the fields are as follows: - Rail Grade (Reported) - Rail Type (Reported) - Weld Type (Reported) - Welding Machine SN (Reported) - Welding Head SN (Reported) - Welding Contract (Reported) - Welding Operator (Reported) - Weld ID (Reported) The Rail Grade and Rail Type are displayed on the Main Screen, after being inserted, for reference.
  • [GT-250-PE OPERATION] April 22, 2014 9 Bend History - Operator The "Bend History" button will bring up the folder in which all the slow bend test reports are stored on the USB mass storage device. This will contain only the bend tests saved on the currently inserted USB mass storage device. To return to the interface simply close the window or press the touch-screen anywhere outside the history window.
  • [GT-250-PE OPERATION] April 22, 2014 10 User Selection Screen The "Log Off" button will bring up the User Selection screen. The interface provides 2 user levels: Operator and Supervisor. Either user is not properly logged off until the inactive user level becomes active. Each user level has a different level of control within the interface. Further detail will be provided at Bend History - Supervisor. By selecting either user level, the interface will bring up the appropriate login screen.
  • [GT-250-PE OPERATION] April 22, 2014 11 Authenticate - Operator By pressing the "Operator" button within the "User Select" screen the interface will bring up the authentication screen for the Operator user level. If this user was logged in when pressing the "log off" button and no user switch has occurred, the Login button will be active and offers straight login without the need to insert the appropriate password. In the event that this is an actual user switch, the "Login" b
