6 Control and display
UNIGAS 300 is simple to operate. Only four navigation keys allow easy navigation through the menu.
Navigation keys
▼
and
▲
allow navigation between screens and menu functions. Navigation keys
►
and
◄
are used to access or leave a menu or submenu. These navigation keys are also used to refresh or confirm
certain data.
When not in use, the display is switched off to save energy. When one of the keys is operated, the first main
screen will be displayed. Then
▼
will activate the second main screen or
►
will activate the menu.
Chapter 10 provides a list of all available registers, complemented by a brief explanation and the position in
the menu.
Main screens
Figure 8. Main screen status bar
1:
LF impulse input indicators of impulse inputs 1, 2, and 3
2:
LF impulse output indicators of impulse outputs 1 and 2
3:
alarm output indicators of alarm outputs 1 and 2
4:
indicator for remote reading
5:
battery condition indicator where a fully coloured symbol indicates a full battery and a less than
fully coloured symbol indicates a partly empty battery. Check the value in UNIGAS 300 menu item

blinking, indicating that the battery has to be replaced. Dependent on the battery type and
application, the remaining capacity is sufficient for 1 year (D cell) or 1.5 year (DD cell) of operation.
