1GENERAL 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.

•Dixell S.r.l. reserves the right to change the composition of its products, even without notice,

ensuring the same and unchanged functionality.

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.

2GENERAL DESCRIPTION

Model XWi70K is a microprocessor-based controller suitable for applications on medium or low

temperature refrigerating units. It must be connected by means of a two-wire shielded twisted cable (

1mm) at up to 30 meters to the keyboard CH620, T620T/H or T820T/H. It is provided with five relay

outputs to control compressor, defrost (which can be either electrical or hot gas), evaporator and

condenser fans and light or alarm. It is also provided with 4 NTC or PT1000 probe inputs. It has a both

a frequency output and a serial port which can be used to control variable speed compressors. A couple

of analogue outputs (4-20mA or 0-10Vdc) and a master 2-wire RS485 output for serial controlled

ventilator complete the HW resources.

The HOTKEY I/O port allows connecting the unit, by means of the external module XJ485-CX, to a

network line ModBUS-RTU compatible such as an X-WEB monitoring system. With the HOTKEY port

it is possible to modify the configuration of the controller (by using the Wizmate Progtool Kit).

The instrument is fully configurable and it can be easily programmed through an external keyboard.

3FIXED SPEED COMPRESSOR CONTROL

The regulation uses the temperature measured by the regulation 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 any

regulation probe fault, the compressor management will switch to fixed ON/OFF time mode, as set in

the parameters Con and CoF.

3.1 DOUBLE FIXED SPEED COMPRESSOR CONTROL

The controller can drive double compressor circuits. To do this, a couple of relays need to be properly

configured: oAx=CP1 and oAy=CP2. (do not use oA5 for compressor management). The parameters

used for this kind of regulation are the following:

Compressor anti-short-cycle delay

AC1

Second compressor anti-short-cycle delay

2CC

Activation mode for second compressor (valid if oAx=CP1 and oAy=CP2)

rCC

Compressors rotation enabled

Cdd

Maximum time with compressor active

The second compressor output is activated by following the 2CC parameter:

-If 2CC=FUL then in parallel with the relay of the first compressor (CP1), with a possible

delay as set in the AC1 parameter. Both compressors are switched off at the same time.

-If 2CC=HAF then only if the temperature T>SET+HY+HY1. The delay AC1 is always

respected. The second compressor is deactivated when T<SET+HY.

With parameter rCC it is possible to enable the compressor rotation function: the activation of the first

and the second compressor will be alternated to equalize the number of working hours of both of them.

In case of hot gas defrost operation, it is possible to select if one or both compressors will be used.

3.2 PULL DOWN

When defrost is not in progress, it can be activated by keeping the UP button pressed for 3 sec. The

compressor will operate to reach the CCS set point by the time set through the CCt parameter. The

cycle can be terminated before the end of the CCt time by using the same activation button (keeping

the UP pressed for 3 sec when PULL DOWN is running)

4DEFROST

Two defrost modes are available through the tdF parameter: defrost through electrical heater

(tdF=EL) and hot gas defrost (tdF=in).

The defrost interval depends on the presence of the RTC (optional). The internal RTC is controlled by

means of the EdF parameter:

-EdF=in: the defrost is made every idF time –standard way for controller without RTC.

-EdF=rtC: the defrost is real time controlled, depending on the day enabled in the parameters

dd1…dd7 and the hours set in the parameters Ld1...Ld6.

Other parameters are used to control defrosting cycles: the maximum length (MdF) and defrosting

modes: timed or controlled by the evaporator’s probe (P2P).

At the end of defrost dripping time is started, its length is set in the Fdt parameter. With Fdt=0 the

dripping time is disabled.

4.1 SYNCHRONIZED DEFROST

This defrost function requires:

-To set a digital input of any controller as ixF=dEF

-To connect (by wire) all digital inputs set as ixF=dEF

A maximum number of 20 controllers can be used in this configuration.

The Synchronized defrost mode is enabled by par. SYd=SYn. After any defrost request (received by

RTC, timed by par. idF, manually by defrost button or by digital input set as dEF), all controllers will

activate their own defrost phase. The first controller which ends its defrost phase will release the defrost

line and load its dripping time. At the end of the dripping time the normal regulation will restart.

The other controllers follow the same logic.

4.2 DESYNCRONIZED DEFROST

This defrost function requires:

-To set a digital input of any controller as ixF=dEF

-To connect (by wire) all digital inputs set as ixF=dEF

A maximum number of 20 controllers can be used in this configuration.

The De-Synchronized defrost mode is enabled by par. SYd=nSY. After any defrost request (received

by RTC, timed by par. idF, manually by defrost button or by digital input set as dEF), all controllers will

load a random delay. The first controller which ends the random delay will retain the ixF=dEF line to

signal to the other controllers that they have to wait before starting their own defrost phases. When the

first controller ends its defrost phase, it will release the ixF=dEF line. The other ones will repeat the

same procedure. The total defrost phase will end when all controllers complete their own defrost phases.

NOTES:

-take care about the time available to complete the defrost phase. It must be used for selecting

the proper MdFvalue

-all controllers in waiting mode will keep on the normal regulation

4.3 RANDOM DEFROST

A random defrost mode can be enabled by par. Syd=rnd. After any defrost request (received by RTC

or timed by par. idF) a random delay will be added. At the end of the added delay the defrost will start.

The random function lead to desynchronize the start of the defrost phases in those cases where more

than a cabinet is installed in the same “island”. The maximum defrost delay is linked to the following

parameters:

-Mdf=maximum time for any defrost

-ndE=delay multiplier

by the following formula:

MAX_DEFROST_DELAY = Mdf*ndE (min)

For example: if ndE=10 and Mdf=20 min, this means that the total interval of time used by any device

for complete its defrost phase is 200 min (worst case).

NOTE:

-take care about the interval of time available for defrost. It must be used for selecting both MdF

and ndE values

-the higher is the ndE value and the better is the result in terms of desynchronization. On the

other side, the longer will be the total interval of time required to complete defrosts

5FAN MANAGEMENT

The controller can manage the following type of fans:

-Fixed speed fans (oAx=FAn, Cnd)

-Variable speed fans with 0-10V or 4-20mA control signal (1Ao or 2Ao=FAn, Cnd)

-Variable speed fans with Modbus control signal (EBM models only)

5.1 MODBUS FAN SUPPORTED

It is possible to use up to 4 fans with EBM Modbus communication protocol. The following parameters

need to be properly configured:

-S00: number of condenser fan controlled via Modbus

-C01 to C04: serial address for condenser fans

-vdF: serial output for fan management enabled

1592026601 XWi70K STD FULL EN r1.6 2022.07.29.docx XWi70K 2/15

NOTE:

-All configured fans must have a valid Modbus address

-The internal logic controls the available fans in parallel mode: all (configured) fans will receive

the same speed command.

-Set S00=0 to disable condenser fans controlled via Modbus

6EVAPORATOR FAN CONTROL

The evaporator 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.

The par. FAP is used to select which temperature probe will be used from the evaporator fan regulator.

A specific setpoint (par. FSt) provides the temperature value, 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-HYF.

6.1 FORCED ACTIVATION FOR EVAPORATOR FANS

This function, managed by the FCt parameter, is designed to avoid short cycles of fans, that could

happen when the controller is switched on or after a defrost, when the room air warms the evaporator.

If the difference between the evaporator temperature and the room temperature is higher than the FCt

value, the controller will activate the fans. This function is disabled if FCt=0.

6.2 CYCLIC ACTIVATION OF THE FANS WHEN THE COMPRESSOR IS OFF

When FnC=C-n or C-Y (fans in parallel to the compressor), the fans will be able to carry out on and off

cycles even if the compressor is switched off. The on and off interval of time follow the Fon and FoF

parameters. When the compressor is stopped, the fans will go on working for the Fon time. On the other

side, with Fon=0 the fans will stay always off when the compressor is off.

7CONDENSER FAN CONTROL

The condenser fan control mode is selected by means of the FCCparameter:

FCC = C_n: fans will switch ON and OFF with the compressor and not run during defrost;

FCC = o_n: fans will run even if the compressor is off, and not run during defrost;

FCC = C_Y: fans will switch ON and OFF with the compressor and run during defrost;

FCC = o_Y: fans will run continuously also during defrost.

The par. FAC is used to select which temperature probe will be used from the condenser fan regulator.

This regulator uses a specific setpoint (par. St2) and differential (par. HY2) to activate and deactivate

the condenser fans:

-If T>St2+HY2 the condenser fans are activated

-If T<St2 the condenser fans are deactivated.

The par. FCo can be used to keep the ventilators active for a period after compressor OFF.

7.1 MODBUS CONFIGURATION

In case of fan controlled via Modbus, the following parameters need to be properly configured:

CMi: minimum speed in percentage

CMA: maximum speed in percentage

CSS: safety speed in case of any communication od regulation error

8AUXILIARY REGULATORS

Up to 2 auxiliary regulators can be used. Both can be linked:

-To a digital output (relay) for ONOFF regulation

-To an analogue output for proportional regulation

The parameters used to configure the auxiliary regulators are the following:

9ANALOGUE OUTPUTS

The controller is equipped with 2 configurable analogue outputs, type 4-20mA or 0-10Vdc (both

selectable). It is possible to use them for proportional regulation of:

-Evaporator fan speed

-Condenser fan speed

Or as proportional output linked to the:

-Auxiliary regulator 1 (linked only to analogue output 1)

-Auxiliary regulator 2 (linked only to analogue output 2)

The parameters used to configure the analogue outputs are the following:

10 VARIABLE SPEED DRIVE CONTROL

10.1 FREQUENCY MODE

The controller can drive variable speed drives with frequency control input. The frequency output port

can issue a frequency signal from 0 to 200Hz, duty cycle=50%. A special cable must be used to connect

the frequency output of the controller to the frequency input of the specific inverter.

-CAB/EMB2: cable DD900002 20 for Embraco models

-CAB/SE1: cable DD900002 21 for SECOP NLV models

NOTE:

-An inverter compressor is totally controlled from the frequency output.

-Due to maximum current value of the frequency driver, only one compressor can be connected

when frequency mode is used.

10.1.1 CABLES FOR FREQUENCY MODE CONTROL

EMBRACO

GRAY →GND (-)

PINK →FREQ (+)

SECOP

R- →GND

R+ →FREQ

10.2 SERIAL MODE CONTROL

The controller can drive variable speed compressors with serial control input. The speed command will

use RPM’s (from 0 to 4500rpm) instead of values in Hertz. A special cable must be used to connect the

serial port of the controller to the serial port of the relative inverter.

-CAB/EMB 1.5MT: cable DD190001 51 for Embraco models

-CAB/SE2 1.5MT: cable DD190001 52 for SECOP NLV models

10.2.1 CABLES FOR SERIAL MODE CONTROL

EMBRACO

SECOP

10.3 PARAMETERS

The regulation band is from SET to SET+HY+HY1. When the regulation is running, the compressor

speed is continuously calculated and updated by the PI regulator.

I case of regulation probe error, the compressor speed will be set to the value of par. SPi.

It is possible to enable a cyclic or a continuous mode operation both during normal mode and energy

saving mode:

-CMn, CME = Y: after reaching the SETPOINT the VSC will keep on running

-CMn, CME = n: after reaching the SETPOINT the VSC will be stopped

10.4 HOT GAS DEFROST

If hot-gas defrost is selected, it will be possible to set the compressor speed by using par. Aod.

10.5 PULL DOWN

An automatic function named PULL DOWN is implemented. This function forces the controller to work

at FMA until reaching a specific SETPOINT (par. CCS) for a maximum interval of time (par. CCt). The

PULL DOWN function is activated:

-At start-up if the temperature measured from the regulation probe is higher than the

SET+HY+HY1

-After any defrost

-If the temperature measured from regulation probe go over the SET+HY+HY1+oHt value.

If one of the above conditions happens, the controller will maintain the maximum compressor speed

(FMA) until reaching the CCS setpoint. The maximum interval of time for any PULL DOWN is defined

from par. CCt. At the end of any PULL DOWN it is possible to set an interval of time (par. t1F) with

predefined compressor speed (FMi).

10.6 OIL MIGRATION CONTROL (VALID ONLY FOR VSD)

To avoid oil migration during variable speed compressor operation, a lubrication control is implemented.

If the compressor works with a speed lower than the MnP threshold for tMi time, then the compressor

speed will be increased to FMA for tMA time.

NOTES:

-MnP= FMi to FMA, nu, OFF

-If MnP=nu, then this function is disabled

1592026601 XWi70K STD FULL EN r1.6 2022.07.29.docx XWi70K 3/15

-If MnP=oFF, then the compressor will be stopped for tMA if it works continuously for tMi

10.7 PI ALGORITHM

The VSC regulator implements a PI (Proportional-Integral) algorithm to guarantee temperature stability

11 SPECIAL FUNCTIONS

By using the parameters oAx it is possible to configure the functions of the relay outputs as described

in the following paragraphs:

11.1 LIGHT RELAY (oAx = LiG)

By setting oAx=Lig the relay will work as light relay, it is switched on and off by the light button on the

keyboard and is affected by status of the digital input when i1F=dor.

The parameter LHt (Light timer) sets the time the light will stay on after pressing the light switch on the

keyboard. Every time the key is pushed the timer is re-loaded.

11.2 SECOND COMPRESSOR MANAGEMENT (oAx = CP2)

By setting one of the parameters oAx=CP2, the correspondent relay will operate as “second

compressor”. It will be activated in parallel with the relay of the first compressor, with a possible delay

set in the AC1 parameter (seconds).

11.3 ON/OFF RELAY (oAx = onF)

By setting one of the parameters oAx=onF, correspondent the relay will operate as “on-off” relay: it will

be activated when the controller is switched on and it will be switched off when the controller is in stand-

by status.

11.4 ALARM RELAY (oAx =Alr)

By setting oAx=ALr the correspondent relay will work as alarm relay, it is switched on when an alarm

happens.

Parameters involved:

-tbA (n, Y) Alarm relay silencing

-AoP (cL; oP) Alarm relay polarity

11.5 ANTI-SWEAT HEATER (oAx =tiM)

If oAx=tiM, the correspondent relay will be able to work as Anti-Sweat Heater output.

The relay will work based on the parameters btA (base time setting: seconds or minutes), AtF (output

OFF time) and Ato (output ON time) with the following logic: the relay output will cycle (starting with the

OFF time) between OFF and ON status.

11.6 ENERGY SAVING TIMEOUT

If the Energy Saving function has been activated by buttons or digital input, the Energy Saving will be

automatically deactivated once the time defined in the parameter ESt is expired. If the value of ESt=0

the timeout is not considered and the Energy Saving, once activated by button or digital input, can be

deactivated only manually by the user.

11.7 DEAD BAND (oAx =db)

By setting oAx=db the controller will perform a

“dead band” regulation.

The heating element has to be connected to the

correspondent relay.

If the temperature increases and reaches set

point plus differential (HY) the compressor is

started and then turned off when the temperature

reaches the set point value again.

If the temperature decreases and reaches the set

point minus differential (HY) the output (heater)

is switched on and then turned OFF when the

temperature reaches again the set point.

16 DIGITAL INPUT

The free voltage digital inputs are programmable in different configurations by the i1F or i2F

parameters.

16.1 DOOR SWITCH INPUT (dor)

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 did, the door alarm is enabled, the

display shows the message “dA” and the regulation restarts is rtr = yES. The alarm stops as soon as

the external digital input is disabled again. With the door open, the high and low temperature alarms are

disabled.

16.2 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 doesn’t change. The alarm stops just after the digital input is de-

activated.

16.3 SERIOUS ALARM MODE (bAL)

When the digital input is activated, the unit will wait for did delay before signalling the “CA” alarm

message. The relay outputs are switched OFF. The alarm will stop as soon as the digital input is de-

activated.

16.4 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 “CA” pressure alarm message will be displayed. The compressor and the

regulation are stopped. When the digital input is ON the compressor is always OFF. If the nPS

activation in the did time is reached, switch off and on the instrument to restart normal

regulation.

16.5 AUXILIARY OUTPUT CONTROL (AUS)

To activate and deactivate the auxiliary output

1592026601 XWi70K STD FULL EN r1.6 2022.07.29.docx XWi70K 8/15

16.6 DEFROST CONTROL (dEF)

It starts 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.

16.7 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.

16.8 HOLIDAY MODE (HdF)

Holiday mode activation.

16.9 REMOTE LIGHT CONTROL (LIG)

To manage the light activation from remote.

16.10 REMOTE ON OFF (onF)

To issue a remote ON/OFF command.

16.11 PARAMETER MAP CHANGE (Lnt)

To change the used parameter map from nt (first configuration or “normal temperature”) to Lt (second

configuration or “low temperature”) and vice-versa.

16.12 DIGITAL INPUTS POLARITY

The digital input polarity depends on the i1P or i2P parameters:

i1P or i2P=CL: the input is activated by closing the contact.

i1P or i2P=OP: the input is activated by opening the contact

17 HOW TO INSTALL AND MOUNT

The controller XWi70K shall be mounted in a din rail and in a horizontal position or with the relay output

on the bottom side (IEC/60730).

It must be connected to the keyboard by using a 2-wire cable (1mm). The temperature range allowed

for correct operation is 0 to 60°C. Avoid places subject to strong vibrations, corrosive gases, excessive

dirt or humidity. The same recommendations apply to probes. Let the air free to circulate by the aeration

holes.

17.1 XWi70K –8 DIN CASE - DIMENSIONS

18 ELECTRICAL CONNECTIONS

XWi70K is provided with screw terminal blocks to connect cables with a cross section up to 2.5 mm2 for

the RS485 (optional) and the keyboard. To connect the other inputs, power supply and relays, XWi70K

is provided with Plug-in connections (6.3mm). Heat-resistant cables must 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, in case of heavier loads use a suitable external relay.

NOTE:

-The maximum current allowed for the common line of the relays is 14A (IEC/60730)

-The maximum current allowed for insulated relay (oA5) is 3A (IEC/60730)

18.1 PROBE CONNECTIONS

The probes shall be mounted with the bulb upwards to prevent damages due to 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.

19 TTL/RS485 SERIAL LINE

The TTL connector allows, by means of the external module TTL/RS485 (XJ485CX), to connect the unit

to a network line ModBUS-RTU compatible as the Dixell monitoring system. The same TTL connector

is used to upload and download the parameter list of the “HOT-KEY”.

20 HOW TO USE OF THE “HOT KEY”

NOTE: the XWi controllers need a 64KB HOT KEY (Dixell code: DK00000300). Standard Hot Key is not

supported.

20.1 PROGRAM A HOT-KEY FROM AN INSTRUMENT (UPLOAD)

1. Program one controller with the front keypad.

2. When the controller is ON, insert the “HOT-KEY” and push UP button; the “uPL”message

appears followed a by a flashing “End” label.

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

4. Turn OFF the instrument, remove the “HOT-KEY” and then turn it ON again.

NOTE: the “Err” message appears in case of a failed programming operation. In this case push again

button if you want to restart the upload again or remove the “HOT-KEY” to abort the operation.

20.2 HOT TO CHANGE PARAMETER MAP BY USING AN HOT-KEY

(DOWNLOAD)

1. Turn OFF the instrument.

2. Insert a pre-programmed “HOT-KEY”into the 5-PIN port and then turn the Controller ON.

3. The parameter list of the “HOT-KEY” will be automatically downloaded into the Controller

memory. The “doL” message will blink followed a by a flashing “End” label.

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

5. Remove the “HOT-KEY”.

NOTE: the message “Err” is displayed 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.

21 INTERNAL MEMORY

The controller has an internal memory where are stored:

-Parameter maps nt and Lt

-Factory default configurations for both nt and Lt parameters map

The controller is always shipped with:

-Parameter map nt = factory default configuration “nt”

-Parameter map Lt = factory default configuration “Lt”

Any modification to parameter map nt or Lt does not change factory values.

It will be possible to restore factory defaults values for nt or Lt parameters map by using UP2=CC

function.

NOTES:

-If controller is using nt parameter map, the factory default configuration nt will be reloaded

overwriting nt parameter map. The same for parameter map Lt.

-The factory default configurations are read only (it is not possible to modify them on the field).
