The scheduler is a powerful graphic tool to manage commands sent to the

controllers. You can quickly see an overview of all daily activity. This means that

energy saving routines and defrosts can be easily scheduled.

This highly appreciated function allows one to verify the right temperature for

single devices (wall cabinets, benches, rooms, etc.). The graphic layout offers a

complete vision about the plant operating mode.

The XWEB can supply powerful graphs, able to represent multiple analogue

variables on the same pictorial system and the course of the status of the outputs

and alarms. This allows the user to have a precise snapshot view of important

variables, for easy diagnosis of faults. Thanks to the high sampling rate of circular

graphs, they are more detailed and appreciated by service for diagnostics.

The connection to the modern supervising systems (of Dixell) allows, thanks to the

special CRO algorithm (Compressor Rack Optimization), to manage the compressor

rack set point in the best possible way, depending on the devices connected,

resulting in plant optimization and energy saving. The system, equipped with

the CRO function, analyzes the information from the controller to determine if

a controller needs more refrigeration power and how much. The set point will be

recalculated in order to satisfy the worse instance and sent from the supervising

system to the XC1000D compressor rack controller; this will be the new working

set point. If the supervising system can’t manage the XC1000D, it’s the controller

that “decides” to replace the set point (coming from the system) and will then re-

deﬁne the set point in the planning phase of a refrigeration plant. The 2 graphs

emphasize that when the CRO algorithm is active, in a real installation, the set

point becomes on average higher, and consequently the energy consumption

decreases. The dotted line represents the average weekly value.
