MicroTech III Controller Operation
The password field initially has a value **** where each *
represents an adjustable field. These values can be changed by
entering the Edit Mode described below.
Figure 69: Password Entry Page
Entering an invalid password has the same effect as continuing
without entering a password.
Once a valid password has been entered, the controller allows
further changes and access without requiring the user to enter a
password until either the password timer expires or a different
password is entered. The default value for this password timer
is 10 minutes. It is changeable from 3 to 30 minutes via the
Timer Settings menu in the Extended Menus.
Navigation Mode
In the Navigation Mode, when a line on a page contains no
editable fields all but the value field of that line is highlighted
meaning the text is white with a black box around it. When the
line contains an editable value field the entire line is inverted
when the cursor is pointing to that line.
When the navigation wheel is turned clockwise, the cursor
moves to the next line (down) on the page. When the wheel is
turned counter-clockwise the cursor moves to the previous line
(up) on the page. The faster the wheel is turned the faster the
cursor moves.
When the Back Button is pressed the display reverts back to
the previously displayed page. If the Back button is repeated
pressed the display continues to revert one page back along the
current navigation path until the “main menu” is reached.
When the Menu (Home) Button is pressed the display reverts
to the “main page.”
When the Alarm Button is depressed, the Alarm Lists menu is
displayed.
Edit Mode
The Editing Mode is entered by pressing the navigation wheel
while the cursor is pointing to a line containing an editable
field. Once in the edit mode pressing the wheel again causes
the editable field to be highlighted. Turning the wheel
clockwise while the editable field is highlighted causes the
value to be increased. Turning the wheel counter-clockwise
while the editable field is highlighted causes the value to be
decreased. The faster the wheel is turned the faster the value is
increased or decreased. Pressing the wheel again cause the new
value to be saved and the keypad/display to leave the edit
mode and return to the navigation mode.
