INTERPRETING THE %COOL

From an ideal point of view the highest the percentage is, the better the compressor rack has been
tuned. Of course if many devices work with a percentage next to 100% it means that quite probably
during the worst condition case some devices may fail to receive the correct amount of cooling. Use the
data provided by "Performance meter" according to your experience. This software tool can be useful
also when the majority of the devices (belonging to the same typology) work within a certain range and
only one reports a different value. Quite probably that one is not working properly.

GLOBAL COMMANDS

This function allows the user to load a window containing all the global commands previously defined in
the "Global Edit". In the main page go under Device menu and choose "Global Commands".

3.6 CRO (ONLY FOR XWEB WITH CRO)

This propriety algorithm mixes together into a winning software tool the complexity of the refrigeration system
and the easy parameter programming of the user interface. Moreover, once again the software is a JAVA
APPLET, it means no need to install a PC software. Data depends on the seasonal period and varies from
installation to installation. To start the C.R.O., go to "Supervising" then C.R.O. The following windows
appears:

Dixell, thanks to its experience in the industrial refrigeration market and even more
important, thanks to the tight relationship with the customer, has developed a specific
module intended to energy-saving politics. C.R.O. basically works with 2 parameters:
suction pressure of the compressor rack and the worst case cabinet. The former is
detected via a XC1000D controller (ver.1.1 or higher) and XC600CX by Dixell, the
latter is computed according to a special algorithm based on the time-switching of the
solenoid relay.
