Dixell XR40CX-5N1C1 230V Digital Thermostat Controller Compressor Defrost Probes
Model XR40CX, format 32 x 74 mm, is microprocessor based controller, suitable for applications on medium or low temperature refrigerating units. It has 2 relay outputs to control compressor and defrost, which can be either electrical or reverse cycle (hot gas). It is also provided with three NTC or PTC probe inputs, the first one for temperature control, the second one, to be located onto the evaporator, to control the defrost termination temperature, the third one, optional, to connect to the HOT KEY terminals to signal the condenser temperature alarm or to display a temperature. The digital input can operate as fourth temperature probe.The HOT KEY output allows to connect the unit, by means of the external module XJ485-CX, to a network line ModBUS-RTU compatible such as the Dixell monitoring units of X-WEB family. It allows to program the controller by means the HOT KEY programming keyboard.The instrument is fully configurable through special parameters that can be easily programmed through the keyboard.

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“.
In case of fault in the thermostat probe the start and stop of the compressor are timed through parameters “COn” and “COF“.
DEFROST
Two defrost modes are available through the “tdF” parameter: defrost through electrical heater (tdF= EL) and hot gas defrost (tdF = in). 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 evaporator’s probe (P2P).At the end of defrost dripping time is started, its length is set in the FSt parameter. With FSt =0 the dripping time is disabled.
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.
