2. GENERAL DESCRIPTION

Model XW60LS, format 38x185mm, is microprocessor based controller, sui table for applicati ons on medium or low tem peratur e venti lated r efri gerati ng units . It has 3 relay outputs to control com pres sor, fan and defrost, which c an be either electri cal or rever se cycle (hot gas ) It could be provided with a Real Time Clock which allows programmi ng of up to 6 daily defrost cy cles, divi ded into holidays and workdays. A “Day and Night” func tion wit h two different s et points is f itted for energy savi ng. It i s al so provided with up to three NTC or PTC probe inputs, the f irst one for temperatur e control , the second one, to be located onto the evaporator, to c ontrol the defros t term inat ion tem peratur e and to m anaged the fan. Third probe can operates as digital input. The HOT KEY output allows to connect the unit, by means of t he external module X J485-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.

In case of fault i n the thermostat probe the start and stop of the compress or are timed through parameters “COn” and “COF”.

3.2 DEFROST

Two defrost modes ar e avail able t hrough the “tdF” param eter: defr ost thr ough elec tri cal heater ( tdF = EL) and hot gas defrost (tdF = in).

The defrost interval depends on the pres enc e of t he RTC (opt i onal ) . I f the RT C i s pr es ent i s c ont rolled 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 defros t is made i n real tim e depending on the hour s set in the par ameters

Ld1..Ld6 on workdays and in Sd1…Sd6 in holidays; Other parameters are used to control defrost cycles: its maximum length (MdF) and two defrost modes: timed or controlled by the evaporator’s probe (P2P). At the end of defrost drippi ng time is started, its l ength is set in the F dt parameter. Wit h Fdt =0 the dripping time is disabled.

3.3 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 = o_n fans will run even if the compressor is off, and not run during defrost; After defrost, there is a timed fan delay allowing for drip time, set by means of the “Fnd” parameter. FnC = C_Y 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 s etting of temper ature, detected by the evaporator probe, above which the fans are always OFF. This is used to make sure circulation of air only if his temperature is lower than set in “FSt”.

3.3.1 Forced activation of fans

This function managed by the Fct parameter is designed to avoid s hort cycles of fans, that coul d happen when the control l er is switched on or after a defrost, when the r oom ai r war m s the ev apor ator .

12. ELECTRICAL CONNECTIONS

The instruments are pr ovided with s crew termi nal block t o connect cables with a cross section up to

2,5 mm

for the digital and analogue i nputs. Relays and power supply have a Faston connection (6,3mm). Heat-resi stant cables have to be used. Before connecting cables make sure the power supply compl i es with the instrument’s requir em ents . S epar ate t he probe c ables from the power supply cables, from the outputs and the power connecti ons. Do not exceed the maxim um current all owed on each relay, in case of heavier loads use a suitable external relay.

N.B. Maximum current allowed for all the loads is 20A.

12.1 PROBE CONNECTION

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 temper ature. Place the defrost term ination probe among the evaporator fins in the coldest pl ace, w here mos t ic e is form ed, far fr om heater s or f rom t he warmes t plac e duri ng defrost, to prevent premature defrost termination.

13. HOW TO USE THE HOT KEY

13.1 HOW TO PROGRAM A HOT KEY FROM THE INSTRUMENT (UPLOAD)

1. Program one controller with the front keypad.

2. When the controller i s ON, i ns er t the “Ho t key” and push o key; the "uPL" message appears

followed a by flashing “End”

3. Push “SET” key and the End will stop flashing.

4. Turn OFF the instrument remove the “Hot Key”, then turn it ON again. NOTE: the “Err” message is di splayed for failed program ming. In this case push again o key if y ou

want to restart the upload again or remove the “Hot key” to abort the operation.

13.2 HOW TO PROGRAM AN INSTRUMENT USING A HOT KEY (DOWNLOAD)

1. Turn OFF the instrument.

2. Insert a programmed “Hot Key” into the 5 PIN receptacle and then turn the Controller ON.

3. Automatically the parameter li st of the “Hot Key” is downloaded into t he Controller memor y,

the “doL” message is blinking followed a by flashing “End”.

4. After 10 seconds the instrument will restart working with the new parameters.

5. Remove the “Hot Key”.. NOTE the message “Err” is di s pl ay ed for f ai l ed pr ogr am m i ng. I n thi s c as e tur n the unit off and then on if you want to restart the download again or remove the “Hot key” to abort the operation.

14. ALARM SIGNALS

14.1 ALARM RECOVERY

Probe alarms P1”, “P2”, “P3” start some seconds after the fault in the related probe; they automatically stop some seconds after the probe res tarts norm al operat ion. Chec k connec tions before repl acing the probe. Temperature alarms “HA”, “LA” “HA2” and “LA2” automatical ly stop as soon as the temperature returns to normal values. Alarms “EA” and “CA” (with i1F=bAL) recover as soon as the digital input is disabled. Alarm “PA” (with i1F=PAL) recovers only by switching off and on the instrument.
