The window can also be operated using the global window buttons. See "Global Window Feature" previously.

Caution: If express override is activated, the midgate window will not reverse automatically. You or others could be injured and the window could be damaged. Before you use express override, make sure that all people and obstructions are clear of the midgate window path.

Midgate® Window Express Override Mode

If an obstruction or weather condition such as severe icing stops the window as it is moving upward, the window will automatically reverse to a partially open position. The window will return to normal operation once the obstruction or condition is removed.

The window auto-reversal function can be overridden in the express override mode. To override, the window must be operated manually by pressing and holding the Midgate® window switch or the global window button. This must be done within two seconds after the Midgate® window has stopped at a partially open position. The express override mode only works immediately following a window auto-reversal. Window express functions will not work while in this mode.

Midgate® Window Error/Jog Mode

If the Midgate® window has sensed conditions which may lead to damage or malfunction of the window system, the window will automatically go into Error/Jog mode. In this mode, window express functions will not work. The window can only be operated manually by pressing the Midgate® window switch or the global window button. The window will move slightly and stop. Press and hold the window switch or global window button to continue to close the window a small amount at a time.

To Exit Error/Jog Mode

  1. Ensure normal Midgate® window operating conditions have begun.
  2. Press and hold the Midgate® window down switch approximately one second to start window express-down.
  3. Release the window down switch and allow the window to fully open.
  4. Do not use any window switches once window movement has started.

  5. Press the Midgate® window up switch and visually confirm that the express-up has been completed.
