MegaPower LT
Chapter 2: The Menu System
The menu system is used to program the MegaPower LT as required using the keyboard.
This chapter give details about how to use the menu system. Menu operation and navigation
is documented for RS485 keyboards. RS232 keyboard functionality may differ.
Status Levels
There are three different user status levels, two of which have access to the menu system.
Operator – only operates the system. No menu access allowed.
Supervisor – is able to modify settings within the Supervisor menu.
Administrator/Installer – has access to all menu items.
Menu Navigation
A keyboard joystick can be used to navigate the menu system. In general, a menu item is
selected and edited as follows:
1. Use Joystick Up/Down movements to move between menu items. The currently
selected menu item will flash.
2. Use the ENTER key or Joystick Right to select a menu item.
3. In the resulting screen, use:
• The Joystick Up/Down movement to move through the menu items in a screen.
• The Joystick Left/Right to toggle through and select the options for a menu item.
• The numerical keys to input numerical data.
• The SHIFT (
) key held down whilst using Joystick Up/Down movements to
change between capital letters and lower-case.
• The MENU ESCAPE (
) key to return to the previous menu.
NOTES
• When menu items are being edited, automatic functions (e.g. alarms and tours)
cease operating.
• Menus can be displayed on any monitor, however only one monitor can display the
menus at once.
• Any operation calling for the use of the SHIFT (
) key requires this key to be held
down whilst another key is pressed. This is the same way in which the SHIFT key
operates on a PC keyboard.
• When making changes in a screen, use the Joystick Down command to scroll through
the fields, completing each one in turn. Scrolling back up the screen after changes
have been made will cause the changes to be lost.
