1. 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. Dixell Srl 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.
2. GENERAL FEATURES
The series XB has been created for fast chilling or freezing goods according to international food safety standards. Lo strumento dispone delle seguenti funzioni: there are FOUR types of cycles:
* Soft Chilling * Hard Chilling * Soft Freezing
* Hard Freezing At the end of each cycle the instrument switches automatically to Hold mode. The user can select one of them according to his own requirements and modify it as he wants..
Any cycle can be manually terminated before the normal. Each cycle can use up to 3 insert probes or a MultiPoint probe (max 3 points) to be inserted in the product. During the Cycle there are no defrosts and the fans are always on, a defrost cycle can be done before any
freezing cycle.
Each cycle can be divided into 3 phases + hold with dedicated parameters. Low and high temperature alarm management of the condenser. Log of last 15 HACCP alarm incidents (high temperature, power failure and maximum cycle time
exceeded).
Option to activate a delay on instrument startup to enable heating of the compressor carter. Each instrument is provided with an output for remote display The XB590L controller is provided with internal real time clock and can be connected to the XB07PR
printer.
Reading and writing parameters can be managed, in addition from the instrument keyboard, through the
Dixell Wizmate software.

7.2 STRUCTURE OF CHILLING/FREEZING CYCLES (1,2,3,4) - PARAMETERS
Par
Meaning
cyS
Cycle setting tEP: by temperature; The cycle is done according to the rEM parameter. tiM=timed cycle, based on the Pd1, Pd2, Pd3 parameters.
dbC
Defrost before the cycle Y= defrost is carried out with n=the cycle starts immediately without defrosting.
iS 1
Set point for insertion probe first phase OFF= the phase is timed. Other values= When the temperature measured by the three insert probes reaches this value,
the current phase is finished and the next one started.
rS 1
Room probe Set point for the first phase

Pd1
If the cycle is timed (first phase)
it is considered if the insert probe is not present or in the cases described in the section 7.3 (from 00h:00m to 32h00min, res 10 min); at the end of this time it switches to the next phase. If the cycle is of temperature (first phase) this value is used only if there is an insert probe; this is the maximum duration of the first phase if the temperature defined in parameter is1 is not reached
iS 2
Set point for insertion probe second phase OFF= the phase is timed. Other values = When the temperature measured by the insert probes reaches this value, the
current phase is finished and the next one started.
rS 2
Room probe Set point
it prevents temperature from reaching a too low value. This value controls the operation of the compressor.
Pd2
If the cycle is timed (second phase)
it is considered if the insert probe is not present or in the cases described in the section 7.3 (from 00h:00m to 32h00min, res 10 min); at the end of this time it switches to the next phase. If the cycle is of temperature (second phase) this value is used only if there is an insert probe; this is the maximum duration of the second phase in the event the temperature set in parameter iS2 is not reached.
iS3

If the cycle is at temperature (third phase) this value is used only if there is an insert probe; this is the maximum duration of the third phase if the temperature defined in parameter iS3 is not reached
dbH
Defrost before the hold phase Yes=defrost is carried out. No= the hold phase starts immediately. If the hold phase is disabled, defrost is not carried out in
any case.
HdS
Set point of the holding phase
if the value is 50.1°C, the hold phase is disabled.
IMPORTANT NOTE: If the duration time of a phase is set at the OFF value, the corresponding phase is
disabled. For example, if Pd3=OFF the third phase of the cycle is not active.
NOTE2 IMPORTANT: If the phases after the one in progress are disabled, the end-of-cycle message is
displayed.
1592006230 XB590L GB r1.0 29.02.2016 XB590L 12/32
7.3 INSERT PROBE MANAGEMENT
By means of the insert probe, it is possible to monitor the internal temperature of the product and, according to
it, to set the chilling and freezing cycles.
In fact, the different phases shall be completed when the internal temperature reaches the end-of-cycle values
set. If the probe is declared as not present, it is not considered.
If a multipoint insert probe (with 2 or 3 temperature sensors) is used, you must configure the parameters IS1,
IS2, iS3 with the value "MP". In this case, the product temperature, during the Chilling, Freezing or Hold
phases, will be the average of the temperatures measured by the sensors present in the probe.
As shown in the following table, in order to switch from one phase to another, all the insert probes in use must
have reached the end-of-phase temperature, iS1, iS2, and iS3 respectively.
If the current phase is the last one enabled, when an insert probe reaches the iSx temperature, where x = 1, 2
or 3, the lower display shows the labels “End i1P” or “End i2P” or “End i3P” alternately. This message remains
active until a key is pressed. When a key is pressed, the previous view restarts. During the second phase,
when the insert probe reaches the iSx temperature, also the buzzer is activated for the time "bUt" or until a key
is pressed.
If during this time another probe reaches iS3 temperature, the relevant identification message is added on the
display.
E.g.: if i1P and i3P reached iS3, i1Pi3PEnd is displayed.

7.4 CHILLING CYCLE EXAMPLE
The following drawing explains how a Blast Chiller cycle can be done. To simplify, the use of only one insertion
probe is shown.
7.4.1 First phase: “Hard chill”
It is usually used to blast chill food just cooked. It is normally used to fast chill hot foods. E.g. from 80°C / 170°F to 20°C / 70°F During “Hard Chill”, both compressor and fan are always on until the rS1 temperature is reached. At this point compressor is turned on end off so as to keep the temperature of the room at the rS1 value. “Hard
Chill” ends when the temperature measured by the 3 insert probes reach the iS1 value.
7.4.2 Second phase: “Soft chill”
The Soft Chill starts when the Hard Chill ends. It is used to prevent thin layer of ice from forming on the product. The Soft Chill lasts until the temperature measured by the 3 insert probes reach the set point iS2. During Soft Chill the temperature of the room is regulated by the ambient probe with the set point rS2.
7.4.3 Third phase: “Freezing cycle”
Freezing Cycle: used to fast freeze foods.
The Freezing Cycle starts when the Soft Chill ends. During the “Freezing Cycle” both compressor and fan
are always on until the rS3 temperature is reached. At this point compressor and fans are turned on end off so as to keep the temperature of the room at the rS3 value (normally some degrees below iS3). Freezing Cycle ends when the temperature measured by the 3 insert probes reach the iS3 value.
1592006230 XB590L GB r1.0 29.02.2016 XB590L 14/32
7.4.4 End of the freezing cycle and start of the hold phase (selectable)
The end of the freezing cycle is indicated by the sound of the buzzer (and possibly also by the activation of the alarm relay if oA1 or oA2 =ALL). The alarm automatically stops after the “but” time or by pressing any keys. Once the freezing cycle is complete, the instrument automatically starts the hold phase at the temperature set in parameter HdS. If HdS=50.1°C, the hold phase is not carried out and the machine turns off.
NOTE1: with dbH = yES a defrost is done before the holding phase.
NOTE2: If the end cycle temperature iS3 is not reached in the maximum time Pd1+Pd2+Pd3 the instrument
keep on working, but the alarm message “OCF” is given.
8. DEFROST
Interval defrost is enabled only during hold.
In this case, the defrost interval is defined by the parameter idF.
During the defrost cycle, the maximum and minimum temperature alarms are disabled.
If an alarm is already present, these remain also during defrost.
Further possible defrosts are defined by parameters:
- dbC: defrost before cycle.
- dbH: defrost before hold.
Below is the analysis of the sources of possible requests for defrost cycle start.
8.1 DEFROST REQUEST
Defrost request may occur by:
8.1.1 Expiration of interval between defrosts (only during hold)
A fixed interval between the start of a defrost cycle and the next one is expected and can be set using a
parameter (idF). When this interval ends, it is reinitialised and a defrost cycle starts.
8.1.2 Pressing of DEF key (only during hold)
Ensure there are no active cycles or hold is not in progress.
By pressing the UP/DEF key for 3 seconds, a request for defrost is sent, regardless of the interval between
defrosts (idF), which is reinitialised.
NOTE1: during manual defrost, it is possible to both modify the set point of the hold phase and to select a
cycle.
NOTE2: if the temperature detected by the evaporator probe is greater than the end-of-defrost temperature
(dtE), defrost is not carried out and the message “nod” appears on the display-
NOTE 3: to end manual defrosting, keep the corresponding key of the cycle shown in the display pressed for 3
seconds ( for 1 and 3, for 2 and 4).
8.2 TYPE OF DEFROST
The type of defrost, that can be set using a parameter (tdF), can be:
8.2.1 With electric heater (tdF=rE)
by simply turning off the compressor and activating the defrost relay. By simply stopping the compressor, it is
possible to run defrost cycles also without defrost relay.
1592006230 XB590L GB r1.0 29.02.2016 XB590L 15/32
8.2.2 With Hot Gas (tdF=in)
With compressor ON and defrost relay active for the entire duration of defrost. Before activating, the defrost
relay and the maximum duration time of the defrost cycle wait for the possible anti-short cycle delay.
8.3 END OF DEFROST
8.3.1 Timed
If the evaporator probe is absent (EPP=n), the defrost cycle ends at the expiry of the defrost cycle maximum
duration time, which can be set using the parameter (MdF).
Defrost ends in time if within MdF the temperature of the evaporator probe does not reach the value dtE. In
addition, it is terminated in any case if the evaporator probe fails (P2).
8.3.2 Because of temperature
If the evaporator probe is present (EPP=Y) and detects that the end-of-defrost temperature set using the
parameter (dtE) is reached, the defrost cycle ends.
If at the end of the defrost cycle maximum duration time (MdF) the consent temperature is not reached, defrost
ends in any case.
8.3.3 Request for defrost with evaporator probe temperature greater than the end-of-defrost temperature dtE.
If upon the request for defrost the conditions for the end of the defrost cycle (T2>dtE) are met, the defrost cycle does not start at all and the interval between defrosts is reinitialised.
8.4 DRAIN TIME
At the end of the defrost cycle, a Drain time is expected, during which all the adjustment relays are off and the LED flashes. The duration of the Drain time can be set using the parameter (Fdt).
8.5 TEMPERATURE ALARM DELAY AFTER DEFROST
Only if the exclusion time of the temperature alarm control upon start-up is expired, at the end of the defrost cycle, a delay expressed in minutes is loaded, which can be set using the parameter (EdA) for the exclusion of the temperature alarm control. When this time is expired, if a temperature alarm condition is present, the normal temperature alarm delay is loaded (ALd).
8.6 DISPLAY DURING DEFROST
For the entire duration of the defrost cycle, by setting with the parameter (dFd), it is possible to display the following information:
current temperature detected temperature at the beginning of the defrost cycle Set point value dEF message.
At the end of the defrost cycle, the message dEF is replaced by the temperature detected at the beginning of the defrost cycle. At the end of the defrost cycle, the temperature displayed shall be updated as soon as it is lower than the temperature detected at the beginning of the defrost cycle or the Set Point, or when a temperature alarm triggers; otherwise, temperature update shall be carried out at the end of the maximum delay time for temperature update after the defrost cycle set using the parameter (dAd).

10. CONDENSER TEMPERATURE ALARM MANAGEMENT
Managing alarms (ATC or btc) is controlled if one of the probes is configured as a Condenser Probe and when a cycle is active and if the probe is not in alarm. The probes can be configured as a condenser probe are those of the evaporator and those of the insert probe.
When an alarm occurs it is signalled on the display ( + “Atc” or “btc”) and by the buzzer; the silencing of the relay and the buzzer is managed as an actual tbA parameter (Relay silencing). The alarm stops when the temperature falls below the temperature with regard to the HyA differential. Depending on the configuration of the parameters bAc and/or bLc the compressor stops.

12. COMPRESSOR CRANKCASE HEATING DELAY
Compressor crankcase heating delay (CrankCase Heater) is a function which is managed upon instrument start-up (i.e., when the instrument is powered); the parameters for the management of this function are CCH and CCt.
With the CCH parameter it is possible to define how to activate the delay according to the status of the instrument before it is turned off.
If CCH=0, it means that the delay shall be activated only if the device, before it is turned off, was in OFF condition. In this case, when the device is powered, the message OFF shall appear on the display, both during and at the end of the same; if the count is still in progress and the user presses the ON/OFF key to turn the device on, the
label “HoLd” shall appear on the display. This one remains active until the end of the delay count, then the
controller shal be set to stand-by ("stand-by" means as if the ON/OFF key is pressed for the first time when the instrument is OFF). If the ON/OFF key is pressed, the message OFF will appear on the display (and, at the end of the delay, the instrument shall remain in this status).
If CCH=1, it means that the count is considered independently from the status of the device before it is turned off. If the device was OFF, the logic is the same as described above. If the device was in STAND-BY, with a CYLE or HOLD in progress, on the display the message HoLd will be displayed during the entire duration of the delay time; once the delay time has expired, the device will automatically restart from the condition it was in before it is turned off. Note: also in this case, the user can turn the device OFF and the message on the display will change from HoLd to OFF.

The instruments are provided with a screw terminal block to connect cables with a cross section up to 2.5mm2 for probes and digital input. Spade on 6.3 mm heat-resistant wiring for supply and loads. Before connecting cables make sure the power supply complies with the instrument’s requirements. Separate the input connection 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, a suitable external relay has to be used.
N.B. The maximum total current on the loads shall not exceed 20A.
16.1 PROBES 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 temperature. Place the defrost termination probe among the evaporator fins in the coldest place, where most ice is formed, far from heaters and from the warmest place during defrost, to prevent premature defrost termination.
