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. 2. GENERAL DESCRIPTION Model XW260L, 38x185 mm format, is microprocessor based controller suitable for applications on medium or low temperature refrigerating units. It is provided with four relay outputs to control compressor, defrost - which can be either electrical or hot gas - the evaporator fans and the lights. It is also provided with three NTC probe inputs, one for temperature control, one to control the defrost end temperature of the evaporator and the third, optional, for the display. There are two digital inputs (free contact) for the door switch and configurable by parameter. The standard TTL output allows the user to connect, by means of a TTL/RS485 external module, a ModBUS- RTU compatible monitoring system and to programme the parameter list with the “Hot Key”. An optional output for remote display “XW-REP” is available. 3. CONTROLLING LOADS 3.1 THE 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 FAST FREEZING When defrost is not in progress, it can be activated the keypad by holding the XX key pressed for about 3 seconds. The compressor operates in continuous mode for the time set through the “CCt” parameter. The cycle can be terminated before the end of the set time using the same activation key, XX for about 3 seconds. 3.3 DEFROST Three defrost modes are available through the “tdF” parameter: defrost with electrical heater, hot gas or thermostatic defrost. The defrost interval is control by means of parameter “EdF”: (EdF=in) the defrost is made every “IdF” time, (EdF=Sd) the interval “IdF” is calculate through Smart Defrost algorithm (only when the compressor is ON and the evaporator temperature is bigger than “SdF” parameter). At the end of defrost the drip time is controlled through the “Fdt” parameter. 3.4 CONTROL OF EVAPORATOR FANS The fan control mode is selected by means of the “FnC” parameter: FnC=C-n fans will switch ON and OFF with the compressor and not run during defrost:; FnC=C-y fans will run continuously, but not during defrost After defrost, there is a timed fan delay allowing for drip time, set by means of the “Fnd” parameter. FnC=O-n fans will switch ON and OFF with the compressor and run during defrost; FnC=O-y fans will run continuously also during defrost An additional parameter “FSt” provides the setting of temperature, detected by the evaporator probe, above which the fans are always OFF. This can be used to make sure circulation of air only if his temperature is lower than set in “FSt”. 4.

During the defrost time “MdF”, the heater switches On and OFF depending on the evaporator temperature and “dtE” value. in = hot gas (Compressor and defrost relays ON) EdF Defrost mode: in = interval mode. The defrost starts when the time “Idf” is expired. Sd = Smartfrost mode. The time IdF (interval between defrosts) is increased only when the compressor is running (even non consecutively) and only if the evaporator temperature is less than the value in "SdF” (set point for SMARTFROST). SdF Set point for SMARTFROST: (-30÷30 °C/ -22÷86 °F) evaporator temperature which allows the IdF counting (interval between defrosts) in SMARTFROST mode. dtE Defrost termination temperature: (-50,0÷110,0°C; -58÷230°F) (Enabled only when the evaporator probe is present) sets the temperature measured by the evaporator probe which causes the end of defrost. IdF Interval between defrosts: (1÷120h) Determines the time interval between the beginning of two defrost cycles. MdF (Maximum) duration of defrost: (0÷255 min) When P2P = n, no evaporator probe, it sets the defrost duration, when P2P = y, defrost end based on temperature, it sets the maximum length for defrost. dFd Display during defrost: rt = real temperature; it = temperature reading at the defrost start; Set = set point; dEF = “dEF” label; dEG = “dEG” label; dAd Defrost display time out: (0÷255 min) Sets the maximum time between the end of defrost and the restarting of the real room temperature display. Fdt Drain down time: (0÷60 min.) time interval between reaching defrost termination temperature and the restoring of the control’s normal operation. This time allows the evaporator to eliminate water drops that might have formed due to defrost. dPO First defrost after start-up: y = Immediately; n = after the IdF time dAF Defrost delay after fast freezing: (0min÷23h 50min) after a Fast Freezing cycle, the first defrost will be delayed for this time.

ALd Temperature alarm delay: (0÷255 min) time interval between the detection of an alarm condition and the corresponding alarm signalling. dAO Delay of temperature alarm at start-up: (0min÷23h 50min) time interval between the detection of the temperature alarm condition after the instrument power on and the alarm signalling. EdA Alarm delay at the end of defrost: (0÷255 min) Time interval between the detection of the temperature alarm condition at the end of defrost and the alarm signalling. dot Delay of temperature alarm after closing the door : (0÷255 min) Time delay to signal the temperature alarm condition after closing the door. doA Open door alarm delay:(0÷255 min) delay between the detection of the open door condition and its alarm signalling: the flashing message “dA” is displayed. nPS Pressure switch number: (0 ÷15) Number of activation of the pressure switch, during the “did” interval, before signalling the alarm event (I2F= PAL). PROBE INPUTS Ot Thermostat probe calibration: (-12.0÷12.0°C/ -21÷21°F) allows to adjust possible offset of the thermostat probe. OE Evaporator probe calibration: (-12.0÷12.0°C/ -21÷21°F) allows to adjust possible offsets of the evaporator probe. O3 Auxiliary probe calibration: (-12.0÷12.0°C/ -21÷21°F) allows to adjust possible offsets of the evaporator probe. P2P Evaporator probe presence: n= not present: the defrost stops only by time; y= present: the defrost stops by temperature and time. P3P Auxiliary probe presence: n= not present; y= present. HES Temperature increase during the Energy Saving cycle : (-30,0°C ÷ 30,0°C / -22÷86°F) sets the increasing value of the set point during the Energy Saving cycle.

DIGITAL INPUTS The Wing series can support up to 2 free contact digital inputs. One is always configured as door switch, the second is programmable in seven different configurations by the “I2F” parameter. 6.1 DOOR SWITCH INPUT It signals the door status and the corresponding relay output status through the “odc” parameter: no = normal (any change); Fan = Fan OFF; CPr = Compressor OFF; F_C = Compressor and fan OFF. Since the door is opened, after the delay time set through parameter “dOA”, the alarm output is enabled and the display shows the message “dA”. The alarm stops as soon as the external digital input is disabled again. During this time and then for the delay “dot” after closing the door, the high and low temperature alarms are disabled. 6.2 CONFIGURABLE INPUT - GENERIC ALARM (EAL) As soon as the digital input is activated the unit will wait for “did” time delay before signalling the “EAL” alarm message. The outputs status don’t change. The alarm stops just after the digital input is de-activated. 6.3 CONFIGURABLE INPUT - SERIOUS ALARM MODE (BAL) When the digital input is activated, the unit will wait for “did” delay before signalling the “BAL” alarm message. The relay outputs are switched OFF. The alarm will stop as soon as the digital input is de-activated. 6.4 CONFIGURABLE INPUT - PRESSURE SWITCH (PAL) If during the interval time set by “did” parameter, the pressure switch has reached the number of activation of the “nPS” parameter, the “PAL” pressure alarm message will be displayed. The compressor and the regulation are stopped. When the digital input is ON the compressor is always OFF. 6.5 CONFIGURABLE INPUT - START DEFROST (DFR) It executes a defrost if there are the right conditions. After the defrost is finished, the normal regulation will restart only if the digital input is disabled otherwise the instrument will wait until the “Mdf” safety time is expired. 6.6 CONFIGURABLE INPUT - ENERGY SAVING (ES) The Energy Saving function allows to change the set point value as the result of the SET+ HES (parmeter) sum. This function is enabled until the digital input is activated. 6.7 CONFIGURABLE INPUT - REMOTE ON/OFF (ONF) This function allows to switch ON and OFF the instrument. 6.8 DIGITAL INPUTS POLARITY The digital inputs polarity depends on “I1P” and “I2P” parameters. CL : the digital input is activated by closing the contact. OP : the digital input is activated by opening the contact 7.

ELECTRICAL CONNECTIONS The instruments are provided with screw terminal block to connect cables with a cross section up to 2,5 mm2 for the digital and analogue inputs. Relays and power supply have a Faston connection (6,3mm). Heat-resistant cables have to be used. Before connecting cables make sure the power supply complies with the instrument’s requirements. Separate the probe cables from the power supply cables, from the outputs and the power connections. Do not exceed the maximum current allowed on each relay, in case of heavier loads use a suitable external relay. N.B. Maximum current allowed for all the loads is 20A. 8.1 PROBE CONNECTIONS The probes shall be mounted with the bulb upwards to prevent damages due to casual liquid infiltration. It is recommended to place the thermostat probe away from air streams to correctly measure the average room temperature. Place the defrost termination probe among the evaporator fins in the coldest place, where most ice is formed, far from heaters or from the warmest place during defrost, to prevent premature defrost termination. 9. TTL SERIAL LINE The TTL connector allows, by means of the external module TTL/RS485, to connect the unit to a network line ModBUS-RTU compatible as the ����� monitoring system XJ500 (Version 3.0). The same TTL connector is used to upload and download the parameter list of the “HOT KEY“. 10. USE OF THE PROGRAMMING “HOT KEY “ The Wing units can UPLOAD or DOWNLOAD the parameter list from its own E2 internal memory to the “Hot Key” and vice-versa. 10.1 DOWNLOAD (FROM THE “HOT KEY” TO THE INSTRUMENT) 1. Turn OFF the instrument by means of the ON/OFF key, remove the TTL serial cable if present, insert the “Hot Key” and then turn the Wing ON. 2. Automatically the parameter list of the “Hot Key” is downloaded into the Wing memory, the “DoL” message is blinking. After 10 seconds the instrument will restart working with the new parameters. 3. Turn OFF the instrument remove the “Hot Key”, plug in the TTL serial cable, then turn it ON again. At the end of the data transfer phase the instrument displays the following messages: “end “ for right programming. The instrument starts regularly with the new programming. “err” for failed programming. In this case turn the unit off and then on if you want to restart the download again or remove the “Hot key” to abort the operation.
