SPECIAL FEATURES The LCD and LED dryers come with several new features not available with the earlier versions of the Neptune dryers. By pressing a combination of keys, the dryer can be placed into an Advertising Mode or into a Service Mode for the service technician. ADVERTISING MODE This mode will continuously display the LEDs on the keyboard or illuminate the touch screen. LED Dryer Pressing the damp dry and sensor dry keys for 5 seconds will start the washer in the Advertising mode.
PAGE 59
To aid the service technician, special software was incorporated into the control boards of the MDE/DG5500 & MDE/DG7500 dryers. The software is used to monitor several functions of the dryer during operation and identify any abnormalities as they arise. These abnormalities can be monitored in the Service Mode and the board will list previously identified failures as either a Help or a Diagnostic code.
PAGE 60
The down arrow key will sequence down the list one each time it is pushed with no wrap. The first time the down arrow key is pushed the display will sequence to the next code logged. The last code being displayed being the oldest code. The up arrow will sequence up the list one code each time it is pushed until it reaches the top code. If there are no diagnostic codes available, ‘00‘ will be displayed for the diagnostic code.
