14Administrator access to the operating system

Each Entellisys Touchscreen HMI computer has been configured to prevent direct access to the computer's operating system. Special user permissions are required to exit the HMI application. If exited, the only function allowed is to restart the computer.

For special cases when access to the computer is required, there is a way for the Entellisys System Administrator to logon to the operating system as an Administrator. This will give the user full access to the computer. It is strongly recommended that the System Administrator limit knowledge of this ability to prevent unauthorized access.

Steps to get Administrator access to the operating system of an HMI Touchscreen Computer:

1.Press Ctrl+Alt+Delete. A Windows Security dialog box will display.

2.Press the Logoff button.

3.Constantly press the Shift key until the login dialog box “Login On Windows as” displays.

4.Enter User Name as “Administrator”.

5.Enter Password as “gestart”.

6.Press the OK button.

CAUTION: The system should never be left unattended in this state since unauthorized access could result in damage to the computer image requiring a new image to be loaded. Always restart the computer to revert to the default state.
