BRAND DIXELL

Model XR70CH, format 32x74mm, is microprocessor based controller, suitable for applications on medium or low temperature ventilated refrigerating units. It has four relay outputs to control compressor, fan, and defrost, which can be either electrical or reverse cycle (hot gas). The last one can be used as light, for alarm signalling or as auxiliary output. It is also provided with up to 4 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 and to managed the fan. The digital input can operate as third temperature probe. The fourth one, to connect to the HOT KEY terminals, is used to signal the condenser temperature alarm or to display another temperature.

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 dIXEL 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.

- Differential: (0.1 to 25.5°C; 1 to 45°F) intervention differential for set point. Compressor Cut IN is Set Point + differential (HY). Compressor Cut OUT is when the temperature reaches the set point.

- Minimum set point: (-100°C to SET; -148°F to SET) sets the minimum value for the set point.

- Maximum set point: (SET to 150°C; SET to 302°F) set the maximum value for set point.

- Thermostat probe calibration: (-12.0 to 12.0°C; -21 to 21°F) allows to adjust possible offset of the thermostat probe.

- Evaporator probe presence: (n; Y) n = not present, the defrost stops by time;Y = present, the defrost stops by temperature.

- Evaporator probe calibration: (-12.0 to 12.0°C; -21 to 21°F) allows to adjust possibleoffset of the evaporator probe.

- Third probe presence (P3): (n; Y) n = not present, the terminals 18-20 operate asdigital input; Y = present, the terminals 18-20 operate as third probe.

- Third probe calibration (P3): (-12.0 to 12.0°C; -21 to 21°F) allows to adjust possibleoffset of the third probe.

- Fourth probe presence: (n; Y) n = Not present; Y = present.

- Fourth probe calibration: (-12.0 to 12.0°C; -21 to 21°F) allows to adjust possible offset of the fourth probe.

- Outputs activation delay at start up: (0 to 255min) this function is enabled at the initial start up of the instrument and inhibits any output activation for the period of time set in the parameter.

- Anti-short cycle delay: (0 to 50min) minimum interval between the compressor stop and the following restart.

- Percentage of the second and first probe for regulation: (0 to 100; 100=P1, 0=P2) it allows to set the regulation according to the percentage of the first and second probe, as for the following formula (rtr(P1-P2)/100 + P2).

- Compressor ON time during continuous cycle: (0.0 to 24h00min, res. 10min) allows to set the length of the continuous cycle. Compressor stays on without interruption during CCt time. This is useful, for instance, when the room is filled with new products.

- Set point for continuous cycle: (-55 to 150°C; -67 to 302°F) it sets the set point used during the continuous cycle.

- Compressor ON time with faulty probe: (0 to 255min) time during which the compressor is active in case of faulty thermostat probe. With Con=0 compressor is always OFF.

- Compressor OFF time with faulty probe: (0 to 255min) time during which the compressor is OFF in case of faulty thermostat probe. With CoF=0 compressor is always active.
