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. No functions will be run except illuminating the LEDs.

All the LEDs will light within 1.5 seconds in the following order and repeat: start/pause, signal, wrinkle prevent, wrinkle release, air fluff, damp dry, less dry, normal dry, more dry, very dry, cool down, wrinkle prevent indicator, temperatures (regular, medium, low, extra low), sensor dry, time dry, time(+), time(-), 7 segment display.

Enter and exit the advertising mode by using the same 2 key sequence or unplug the power cord.

LCD Dryer

This mode will continuously display the touch screen on the keyboard.

Pressing the favorites and back keys for 5 seconds will start the dryer in the Advertising mode. No functions will be run except illumination of the touch screen panel.

16023110

While in advertising mode, the display will cycle through eleven screens. If the touch screen or any key (except off) is pressed, the advertising sequence will be interrupted and the control will go to the Interactive State.

When this occurs, the user is able to navigate through the control as normal (including setting favorites, setting preferences, etc.), but the machine will not be allowed to run a cycle. The only methods of exiting the advertising mode is to remove power from the machine or to press and hold both the help key and the favorites key for 5 seconds. The off key will not be active in the service mode.

After 5 minutes of inactivity in the advertising mode, the control will time out and return to advertising mode and the advertising sequence will begin again. When the control times out in this manner, any settings or changes that the user had made while in the advertising mode will not be remembered.

SERVICE /DIAGNOSTIC MODE

This mode provides service personnel the ability to verify the operation of the dryer.

The service mode can be implemented in the middle of any dry cycle. While in the service mode, the servicer can start special service tests such as a system check mode, membrane pad check, display software revision number and display diagnostic/help code listings. (See Service Mode Table) The diagnostic/help code information displayed provides information about the machine.
