GEMS colour displays support 16 screens. The display also has a monitor screen which enables
permanent monitoring of data. To display a screen, select it from the screen menu.
5.1
The Monitor Screen
Normally a given output is only monitored if used by a gauge on the currently displayed screen. In
certain circumstances however, it is necessary to monitor some outputs irrespective of whether or
not they are used by the currently displayed screen page. For example, if the maximum coolant
temperature is required as an output for some screens, switching screens deletes the output as
the screen changes and recreates it if necessary. The maximum output is then be reset and its'
information is lost. By adding this output to the monitor page it is created when the colour display
is switched on. Changing screens has no effect on the output and the data is not reset unless a
reset signal is received.
Furthermore, outputs added to the monitor screen are automatically stored in non-volatile
memory. Thus, the value of a min, max or average output added to the monitor screen is
preserved even when the screen is powered off. Consequently, it is important to make sure a
reset method
is set for such outputs added to the monitor screen.
Select Display | Monitor to view the monitor screen setup. Add the outputs to be continuously
monitored to the list.

Setting Screen and Default Colours
The Colour menu allows the default colours to be specified. These are used whenever a new
gauge is added to a screen. The default colours can be overridden in the individual gauge
properties.
