5.10 XR75CX 5.6
The XR75CX is a microprocessor based controller,
suitable for applications on medium or low temperature
ventilated refrigeration units. It has four (4) relay outputs
to control compressor, fan, and defrost, which can be
either electrical or reverse cycle (hot gas) and light
(configurable).
It can also have up to four (4) NTC, CtC (EU or US
type) probe inputs. The first probe is used for temperature
control. The second probe is used to control the defrost
termination temperature at the evaporator. One of the two
(2) digital inputs can operate as a third temperature probe.
The fourth probe is used to control the condenser
temperature (for condenser alarm management) or to
display a temperature value. Set the PbC parameter to CtC
to support standard Emerson Retail Solutions temperature
sensors (factory default).
The controller is fully configurable through special
parameters that can be easily programmed through the
keyboard.
