2. GENERAL DESCRIPTION
Models XW270K and XW271K are microprocessor based controllers suitable for
applications on medium or low temperature refrigerating units. They must be
connected by means of a two-wire cable (∅1mm) at a distance of up to 30 meters
to the keyboards T820 or T821. They are provided with six relay outputs to control
compressor, defrost - which can be either electrical or hot gas - the evaporator
fans, the lights, the alarm and an auxiliary output. In XW271L the auxiliary output is
configured as anti-condensing heater.
They are 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 RS485 direct 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
èè
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,
èè
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:
C-n = running with the compressor, OFF during the defrost;
C-y = running with the compressor, ON during the defrost;
O-n = continuous mode, OFF during the defrost;
O-y = continuous mode, ON during the 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”.
3.5 AUXILIARY OUTPUT
The auxiliary output is switch ON and OFF by means of the corresponding button
on the keyboard.
The auxiliary output of the XW271K model controls the anti-condensing heater and
it is automatically activated if the room temperature is lower than the “SAA”
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 - RELAY AUX ACTUATION (AUS)
This function allows to turn ON and OFF the auxiliary relay by using the digital input
as external switch.
6.7 CONFIGURABLE INPUT - ENERGY SAVING (ES)
The Energy Saving function allows to change the set point value as the result of the
SET+ HES (parameter) sum. This function is enabled until the digital input is
activated.
6.8 CONFIGURABLE INPUT - REMOTE ON/OFF (ONF)
This function allows to switch ON and OFF the instrument.
6.9 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. INSTALLATION AND MOUNTING
T820 and T821 keyboards shall be mounted on vertical panel, in a 150x31 mm
hole, and fixed using two screws ∅3 x 2mm. To obtain an IP65 protection grade
use the front panel rubber gasket (mod. RG-L). Power modules XW270K and
XW271K shall be mounted in a panel with two or more screws and they must be
connected to the keyboards by means of a two-wire cable (∅1mm). The
temperature range allowed for correct operation is 0 - 60 °C. Avoid places subject
to strong vibrations, corrosive gases, excessive dirt or humidity. The same
recommendations apply to probes. Let the air circulate by the cooling holes.

8. ELECTRICAL CONNECTIONS
XW270K and XW271K are provided with screw terminal block to connect cables
with a cross section up to 2,5 mm2for the RS485(optional) and the keyboard.
Connecting other inputs, power supply and relays, XW270K and XW271K are
provided with 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/RS485 SERIAL LINE
The TTL connector allows, by means of the external module TTL/RS485 (XJ485), to
connect the unit to a network line ModBUS-RTU compatible as the
dIXEL
monitoring system XJ500 (Version 3.0).
The same TTL connector is used to upload and download the parameter list of the
“HOT KEY“. The instruments can be ordered wit the serial output RS485(Optional).
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.
