GENERAL WARNING 1.1 PLEASE READ BEFORE USING THIS MANUAL This manual is part of the product and should be kept near the instrument for easy and quick reference. The instrument shall not be used for purposes different from those described hereunder. It cannot be used as a safety device. Check the application limits before proceeding. 1.2 SAFETY PRECAUTIONS Check the supply voltage is correct before connecting the instrument. Do not expose to water or moisture: use the controller only within the operating limits avoiding sudden temperature changes with high atmospheric humidity to prevent formation of condensation Warning: disconnect all electrical connections before any kind of maintenance. Fit the probe where it is not accessible by the End User. The instrument must not be opened. In case of failure or faulty operation send the instrument back to the distributor or to Dixell S.r.l. (see address) with a detailed description of the fault. Consider the maximum current which can be applied to each relay (see Technical Data). Ensure that the wires for probes, loads and the power supply are separated and far enough from each other, without crossing or intertwining. In case of applications in industrial environments, the use of mains filters (our mod. FT1) in parallel with inductive loads could be useful. Dixell Srl reserves the right to change the composition of its products, even without notice, ensuring the same and unchanged functionality. 2. GENERAL DESCRIPTION Model XR40CX, format 32x74 mm, is a microprocessor based controller suitable for applications on medium or low temperature ventilated refrigerating units. It has two relay outputs to control compressor and fans. It could be provided with a Real Time Clock which allows programming of up to 6 daily defrost cycles, divided into holidays and workdays.It is also provided with up to four NTC or PTC probe inputs: the first one for temperature control, the second one (to be located onto the evaporator) to managed the fan, the third one to signal the condenser temperature alarm and the fourth one as additional temperature probe. By connecting an XJ485-CX external module to the HOT-KEY port, it is possible to link the controller to a ModBUS-RTU compatible network line (such as any dIXEL X-WEB family monitoring unit). It is also possible to program the controller by using an external HOT-KEY memory device. The instrument is fully configurable through special parameters that can be easily programmed through the frontal keyboard 3. CONTROLLING LOADS 3.1 COMPRESSOR The regulation is performed according to the temperature measured by the thermostat probe with a positive differential from the set point: if the temperature increases and reaches set point plus differential the compressor is started and then turned off when the temperature reaches the set point value again. In case of fault in the thermostat probe the start and stop of the compressor are timed through parameters Con and CoF. 3.2 DEFROST Two defrost modes are available through the tdF parameter: defrost through electrical heater (tdF=EL) and hot gas defrost (tdF=in). The defrost interval depends on the presence of the RTC (optional). If the RTC is present is controlled by means of parameter EdF: - with EdF=in the defrost is made every idF time standard way for controller without RTC. - with EdF=rtC the defrost is made in real time Other parameters are used to control the interval between defrost cycles (idF), its maximum length (MdF) and two defrost modes: timed or controlled by the evaporators probe (P2P).

Superior Environmental Control

The XR30CX-5NOC1 ensures accurate regulation of temperature and humidity within refrigeration units. Its robust system supports both heating and cooling functions, ideal for environments requiring stable thermal management. The wide operational range enhances performance in challenging conditions.


User-Friendly and Durable Design

Crafted from high-quality black PVC, the controller is built to withstand regular industrial use while maintaining an unobtrusive appearance. The compact size allows for easy integration within existing systems, and the intuitive user interface streamlines programming and monitoring tasks.


Versatile Application and Reliable Performance

Supporting defrost and fan operations, the controller meets diverse refrigeration demands. Operating on a standard 230V supply and accepting loads up to 3.5A, the XR30CX-5NOC1 adapts to various set-ups seamlessly, ensuring continuous reliability for critical temperature-control applications.
