5.12 XC645CX 2.5
The XC645CX is designed to manage both
compressors and fans in a condensing system such as a
pack. The compressors can be digital scroll, simple,
multistage. Control is by means of a neutral zone or
proportional band 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. Additionally, there
are two inputs for low and high pressure switches: when
these are activated, the system is stopped. The controller
can be easily programmed at power-on by using the Hot
Key. The controller can be connected to the XWEB
controlling and monitoring system, through the TTL
output, using the standard MODBUS RTU protocol.
