XR30CX-5N1C1 Dixell Digital Temperature Controller With 220-240V

GENERAL DESCRIPTION

Model XR30CX, format 32 x 74 mm, is a digital thermostat with off cycle defrost designed for refrigeration applications at normal temperature. It provides two relay outputs, one for the compressor, the other one can be used as light, for alarm signalling or as auxiliary output.. It is also provided with 2 NTC or PTC probe inputs, the first one for temperature control, the second 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 third 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.

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,
