THE DISPLAY
Two LED displays are used in the Heavy Fog Glaciator to show status and
control information. The left display shows all information for the fog
generation functions of the machine, whilst the right display shows the
information for the Ice functions.
Located below each display are 4 function keys that can be used to control
the display and the settings on the machine. The functions of the keys are
shown in the following drawing.
The message displayed will depend on the operating mode of the machine at
the time. However, pressing the menu key at any time will cause the display
to go into the edit mode, allowing the operating parameters to be adjusted.
After approximately 5 seconds since the last keystroke, the display will leave
the edit mode and revert to displaying the current status information.
Pressing the menu key will display the current menu function, whilst pressing
and holding will scroll through the available menus. All keys work the same
way, and can be operated with single keystrokes or held down to force the
display to scroll through the available options/values. The scrolling function
comes into operation 1 second after the key is pressed.
When the user has set the required menu function, pressing the enter key
will display the current value associated with that menu item. The user can
now use the UP/DOWN keys to move through the available options/values
either by single keystrokes or by scrolling.

To store the new value into non-volaile memory, the enter key must be
pressed before moving on to another menu or leaving the edit mode.
When not in edit mode, the display will show information appropriate to the
current operating mode. To do this, the display will alternate between two
messages. The duration of the first message is typically 1 second, whilst the
second message will be visible for 2 seconds. Some messages are
compounded together to form one message, eg FLu/Lo indicating low fluid in
the fluid container.
As an example, when the STANDBY switch on the control panel is set to
OFF (0), the display will alternate between FOG and OFF. For more
information about the messages to expect, see the sections covering the
different control functions on the machine, eg ‘THE TIMER’. The section
entitled ‘DISPLAY MESSAGES’ contains a complete list of the messages
and the circumstances under which they are displayed.
The menus available on each display and the functions they perform are as
follows:
Sets the current Fog output level in the range 0 to 20.
Sets the ON time of the Timer in the range 0 to 90 (seconds).
Sets the OFF time of the Timer in the range 0 to 90 (seconds).
Sets the output density level (Lo,Nor,Hi).
Sets the supply voltage in the range 200 to 250v.
Displays current system temperatures.
The software that controls the displays and the other functions of the
machine is stored in ‘Flash’ memory on the DMX receiver PCB. As new
features become available, this program code can be updated by using the
Martin Uploader programming device for the AVR microprocessor.
