2. GENERAL DESCRIPTION

Model XW60LH, format 38x 185mm, is microproces sor b ased co ntroller , suit able for appli cations on
medium or low temperature ventilated refrigerating units. It has 4 relay outputs to control compressor,
fan, defrost, which can be either electric al or r everse cycle (h ot gas) and a fourth configurable output .
They c ould be provid ed with a Real Time Cl ock which allows programmi ng of up to 6 daily defros t
cycles, divided into holidays and workdays. A “Day and Night” function with two different set points is
fitted for energy saving. They are al s o pr ov i d ed with up to four NTC or PTC probe inputs, the first one
for temperatur e control, the second one, t o be located ont o the evaporator , to control the d efrost
termination t emperature and to m anaged the fan. One of the digital in puts can oper ate as third
temperature pr ob e. T he fourth probe is used t o signal the co nd ens er t emp erat ur e alarm or to dis play
a temperature.
The HOT KEY output al lows to connect t he unit, by me ans of the external m odule XJ4 85-CX, t o 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 instrumen t is fully configurabl e through special paramet ers that can be easily programmed
through the keyboard.

3. CONTROLLING LOADS

3.1 COMPRESSOR

The regulati on is perform ed accordin g

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 i s started an d then tur ned
off when the t emperature re aches the

set point value again.
In case of fault i n the thermostat probe t he start and stop of the com pressor are timed thr ough
parameters Con and CoF.

3.2 DEFROST

Two defrost mo des are av ail able thr ough t he tdF parameter: defr ost thr ough el ectric al hea ter (t dF =
EL) and hot gas defrost (tdF = in).

The defrost i nterval depends on the presence of the RTC (optional). If the RTC is pr esent is
controlled by means of parameter EdF:

- EdF=in: a defrost starts after elapsing the idF time (standard way for controller without RTC).
EdF=rtC: defrosts are sched uled by using a real time cl ock system, dependi ng on the h ours set in

the parameters Ld1..Ld6, during workdays, and in Sd1…Sd6 during holidays.

Other paramet ers are used to control defr ost cycles: i ts maximum le ngth (MdF) and two defrost
modes: timed or controlled by the evaporator’s probe (P2P).
At the end of defros t dri pping ti me is starte d, it s lengt h is set in th e Fdt parame ter. 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;

- 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.

After defrost, t h er e is a tim ed fan delay allowi n g f or drip time, set by mea ns of the Fnd parameter.
An additional paramet er FSt provid es the set ting of t emperat ure, de tected by the eva porator probe,
above which th e fans are always OFF. Thi s is used to make sure cir culation of air only if his
temperature is lower than set in FSt.

3.3.1 Forced activation of evaporator fans

This function , managed by the FCt parameter, is designed to av oid short c ycles of evaporator fans,
which c ould ha ppen whe n the con troller i s switc hed on or af ter a defr ost (wh en the room ai r warms
the evaporator ). If t he temperature differenc e b etwe en the ev a por ator and th e room pr obes is higher
than the value set in the FCt parameter th e fans are switched on. Wit h FCt=0 this function i s
disabled.

3.3.2 Fans cyclic activation with compressor off.

When FnC=C-n or C-Y (fans working in paral lel with the compr es s or ) , by means of th e Fon and FoF
parameters t he f a ns c a n c ar r y out on and off cy c l es ev e n if the compressor is switc h ed off. When th e
compressor i s st op ped t he f ans g o on work in g for the Fon time. Wit h Fon=0 the fans r emai n always
off, when the compressor is off.

3.4 AUXILIARY OUTPUT CONFIGURATION

The functioni ng of the auxili ary relay can b e set by the oAx parameters acc ording to the ki nd of
application. In th e fol l owing paragraph the possible settings are explaided.

3.4.1 Auxiliary thermostat

A possible use i s the anti c ondensing heater, with t he possibil ity of switc hing it on and off also by
keyboard.

Parameters involved:

- ACH: kind of regulation for the auxiliary relay: Ht: heating; cL: cooling;

- SAA: set point for auxiliary relay;

- SHy: differe ntial for auxili ar y rel ay ;

- ArP: probe for auxiliary relay;

- Sdd: auxiliary output off during defrost.

The differential is given by the SHy parameter.
The auxiliar y r el ay c a n be switched on al s o by using the AUX button. In this cas e i t remains on till it’s
manually switched off.

NOTE: If oAx=AUS and ArP=nP (no pr obe for auxiliary outp ut) , the AUX relay can b e activated onl y
by pushing the AUX button of the keyboard.

3.4.2 On/off relay – oAx = onF

In this case the relay is activat ed when the controll er is turned on and de-activate d when the
controller is turned off.

3.4.3 Neutral zone regulation
With oAx=db the AUX relay can control a heater element to perform a neutral zone action.

- output oAx cut in = SET-HY;

- output oAx cut out = SET.

3.4.4 Second compr es sor

With oAx=CP2, the AUX rel ay operat es as secon d compress or: it is acti vated in par allel wit h the
relay of the fir st compressor, with a proper activation delay (set i n the AC1 parameter). Bot h the
compressors are switched off at the same time.

3.4.5 Alarm relay

With oAx=ALr the A UX relay oper ates as alarm r elay. It i s activ ated ev ery tim e an al arm hap pens.
Its status depends on the tbA parameter:

- tbA=Y: the relay is silenced by pr es s i n g any key;

- tbA=n: the alarm relay remains on until the alarm condition recovers.

3.4.6 Night blind management during energy saving cycles

With oAx=HES the AUX relay o perates to m anage the ni ght blind: the relay i s energised w hen the
energy saving cycle is activated by digital input, frontal button or RTC (optional).

message. The r elay out pu ts are s witc h ed OFF . T he al arm w il l st op as so on as th e digi tal inp ut is de­activated.

8.3 PRESSURE SWITCH (i1F or i2F = PAL)

If during the i nterval time set by did param eter, the pressure s witch has reached the number of
activation of the nPS parameter; the “CA” pressure alarm message will be displayed. The
compressor and the r egulati on are stoppe d. Whe n the di gital i nput is ON the compres sor i s always
OFF. If the nPS acti vation in the did time is reached, s witch off and on the instrument to

restart normal regulation.

8.4 DOOR SWITCH INPUT (i1F or i2 F = dor)

normal (any change); FAn: Fan OFF; CPr: Compressor OFF; F_C: C om pressor and fan OF F.
Since the door is ope ned , a fter the delay ti me s et thr ou gh par am eter did, the door al arm is ena bled ,
the display s hows the m essage “dA” and th e regulation rest arts if rtr=YES. The alarm s tops as
soon as the ext er nal digital i npu t is disabled again. With the door open, the hi gh and low temp erature
alarms are disabled.

8.5 START DEFROST (i1F or i2F = dEF)

It starts a defr ost if th ere are t he right c onditi ons. A fter the de frost is finish ed, the n ormal re gulatio n
will restart only if the digital input i s disa bled ot herwis e the ins trume nt will wait unt il the MdF safety
time is expired.

8.6 SWITCH THE AUXILIARY RELAY (i1F or i2F = AUS)

With oAx=AUS the digital input will change the stat us of t h e aux i l iary relay.

8.7 INVERSION OF THE KIND OF ACTION: HE ATI NG-COOLING (i1F or i2F=Htr)

This function allows to invert the regulation of the controller: from cooling to heating and viceversa.

8.8 ENERGY SAVING (i1F or i2F = ES)
