3. General description
The XC650CX is designed to manage both compressors and fans in a condensing system such
as a pack. The compressors can be scroll or Stream, simple or multistage.
It’s possible to manage up to 2 suction circuits with a common condenser.
Control is by means of a neutral zone and is based on the pressure or temperature sensed in the
LP suction (compressors) and HP (condenser) circuits. A special algorithm balances the run hours
of the compressors to distribute the work load uniformly.
The controllers can convert both LP and HP pressures and displays them as temperatures.
The front panel offers complete information on the system’s status by displaying the suction and
condenser pressure (temperatures), the status of the loads, possible alarms or maintenance
conditions.
Each load has its own alarm input that is able to stop it when activated.
By means of the HOT KEY the controller can be easy programmed at power on.
The controller can be connected to the X-WEB, controlling and monitoring system, thanks to the
RS485 serial output, using the standard ModBus RTU protocol.
