ROTRONIC MBW 373 - Manual (Page 16)

System Configuration
You may configure many aspects of the 373 based on your preferences at the time. For
instance, you may easily select which humidity, temperature, and pressure values to indicate on
the screen, the order in which they should appear, their units, and whether each will be shown
as a number or as a graph. In addition to display configuration, you can also change how the
373 performs it’s control functions such as Dew/Frost determination, ORIS control, tube heating,
mirror pre-cooling, etc. Most configuration settings that you change remain valid until the next
time you change them, even if you shut the 373 off.
Menu Options
The 373 has several menus available which are used to configure the system to your
requirements. To activate each of the menus, press the lower right menu key. Notice that it is a
slightly different color than all the other keys on the touch screen.
Each time you press this menu key, the 373 advances to the next menu and the key’s label
changes to indicate which menu is currently active. Once you’ve reached the last menu item,
and press the menu key again, the menu options just start over again at the beginning.
Pressing +/- on the keypad steps backward through the menus. Pressing enter on the keypad
clears all menus from the screen. Note however, that there is no requirement to clear the menus
from the screen for any reason other than cosmetic, or for fear of accidentally changing a
configured option.
Simplified descriptions of each menu follows.
Parameter The Parameter menu is used to select which parameter to display on each of the five
data lines. Each menu item key contains an arrow and directly corresponds with its
adjacent data line.
Numeric /
Graphic The Numeric/Graphic menu is used to toggle a data line between displaying the data
as numbers or as a graph. Each menu item key contains an arrow and directly
corresponds with its adjacent data line.
Control Setup The Control Setup menu is used to configure such things as dew/frost control, pump
control, internal and external heater control, cooling water control, etc.
Units The Units menu is used to change units used for displaying data. Unit changes are
system global, meaning that if the temperature units are changed, then all temperature
values displayed (including dew and frost point temperatures) will appear in the new
units. Since there are so many units that may be configured, there are two units
menus.
Fore Color The Fore Color menu is used to temporarily change the color of the lines drawn on
graphs and the color of text (number and letters). Each data line may be changed
individually. Unlike other selections, changing colors is only temporary and cycling the
power causes the 373 to return to standard color settings.
Back Color The Back Color menu is used to temporarily change the color of the background drawn
on graphs and numeric data lines. Each data line may be changed individually. Unlike
other selections, changing colors is only temporary and cycling the power causes the
373 to return to standard color settings.
Analog
Outputs The Analog Outputs menu is used to configure the calibration, scaling, and parameter
selection for output of data to the Analog Output connectors on the back panel. Both
analog output ports are separately configurable.
