1. GENERAL WARNINGS

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.

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.p.A.” (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 DESCRIPTION

Model XLR470, 32x74 mm format, is a microprocessor based controller, able to control 2 temperatures in an independent way. The first section is suitable for applications on medium or low temperature refrigerating units. It is provided with 3 relay outputs to control

compressor, defrost - which can be either electrical or hot gas - and the evaporator fans. It is also provided with 2 NTC or PTC probe inputs, one for temperature control the other one to control the defrost end temperature of the evaporator. The second section is suitable for applications on medium or low temperature refrigerating units. It is provided with 3 relay outputs to control compressor, defrost - which can be either electrical or hot gas - and the evaporator fans. It is also provided with 2 NTC or PTC probe inputs, one for temperature control the other one to control the defrost end temperature of the evaporator.. There are two digital inputs (free contact) completely configurable by parameters. 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”.

3. TEMPERATURE CONTROL

1. THE COMPRESSOR 1 (2)

For each section, the regulation is performed according to the temperature measured by its own thermostat probe with a positive differential from the set point. If the temperature increases and reaches set point1 (2) plus differential1 (2) 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 “COn1(2)” and “COF1(2)”.

4. DEFROST

1. SECTION 1

For the section 1 two defrost modes are available through the “tdF1” parameter: tdF1= rE defrost with electrical heater tdF1= in or hot gas. The defrost interval is control by means of parameter “EdF1”: rtc (only for instruments with RTC): beginning of defrost cycles is set by the L1d1÷L1d6 parameters during the working days and S1d1÷S1d6

during the holidays

in the defrost is made every “IdF1” time Sd the interval “IdF” is calculate through Smart Defrost algorithm (only when the compressor is ON) At the end of defrost the drip time is controlled through the “Fdt1” parameter.

2. SECTION 2

For the section 2 two defrost modes are available through the “tdF2” parameter: tdF2= rE defrost with electrical heater tdF2= in or hot gas. The defrost interval is control by means of parameter “EdF2”: rtc (only for instruments with RTC): beginning of defrost cycles is set by the L2d1÷L2d6 parameters during the working days and S2d1÷S2d6

during the holidays

in the defrost is made every “IdF” time Sd the interval “IdF” is calculate through Smart Defrost algorithm (only when the compressor is ON) At the end of defrost the drip time is controlled through the “Fdt2” parameter.

3. RELATION BETWEEN DEFROSTS

Different kinds of defrosts are available for each section. The relation between defrosts is set by the dFS parameter: relation between defrosts. 4 relation between the 2 sections of the controller are available, to manage different kinds of applications:

in = independent defrosts; StS = same defrost start, synchronised defrost end; St = same defrost start, independent defrost end; SE = sequential defrost;

• dFS= in - independent defrosts

The defrosts of the 2 sections of controller are completely independent.

First section: defrost interval is set by idF1 parameter. Second section: defrost interval is set by idF2 parameter. The defrost interval is control by means of parameter “EdF1(2)”: in the defrost is made every “IdF1(2)” time Sd the interval “IdF1(2)” is calculate through Smart Defrost algorithm (only when the compressor is ON)

Manual defrost activation, by pushing the DOWN key (defrost 1) or UP key (defrost 2). By pushing the Down key or Up key for 3s, a defrost request is generated for section 1 or 2 respectively. The defrost interval is re-loaded.

• dFS = StS – Same defrost start, end defrost synchronised or dFS = St - Same defrost start, end defrost independent.

The defrost of the 2 sections of controller starts at the same time. idF1 parameter sets the defrost interval for both the sections. The defrosts are performed at regular interval if EdF1 = in or according to the Smartdefrost algorithm if EdF1 = Sd.

With dFS = StS regulation restarts only when defrost is finished for both the sections. The section that finishes the defrost before the other starts dripping time until also the other section has not finished its defrost. Manual defrost activation, by pushing the DOWN key (defrost 1) or UP key (defrost 2). By pushing the Down key or Up key for 3s, a defrost request is generated for both the sections 1 and 2. The defrost interval is re-loaded.

With dFS = St each section restarts regulation as soon as its defrost is finished.

• dFS = SE – sequential defrost

The defrost of 2 sections is synchronised. idF1 parameter sets the defrost interval for both the sections. Defrosts are performed at regular interval if EdF1 = in or according to the Smartdefrost algorithm if EdF1 = Sd. Section 1 does its defrost first, at the end of the defrost of section 1, section 2 starts its defrost.. Manual defrost activation, by pushing the DOWN key (defrost 1) or UP key (defrost 2). By pushing the Down key or Up key for 3s, a defrost request is generated for both the sections 1 and 2. The defrost interval is re-loaded.

5. CONTROL OF EVAPORATOR FANS FOR SECTION 1

Section 1 has 1 relay to control evaporator fan (25-26) The fan control mode is selected by means of the “FnC1” parameter:

FnC1=C-n fans will switch ON and OFF with the compressor and not run during defrost:; FnC1= O-n fans will run continuously, but not during defrost

After defrost, there is a timed fan delay allowing for drip time, set by means of the “Fnd1” parameter.

FnC1=C-y fans will switch ON and OFF with the compressor and run during defrost; FnC1=O-y fans will run continuously also during defrost

An additional parameter “FSt1” 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 “FSt1”.

9. DIGITAL INPUTS

The instrument can support up to 2 free contact digital inputs. Both of them can be configured as One is always configured as door switch, the second is programmable in seven different configurations by the “I2F” parameter.

1.14 DOOR SWITCH INPUT (MP1, MP2, MP)

It signals the door status to the controller: MP1: door open for section 1; MP2: door open for section 2; MP door open for both the sections. When the door is open the status of compressor (and fans) depends on the “odc1” and “odc2”parameters: no = normal (no changes); Fan = Fan OFF (if fan is present); 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.

1.15 CONFIGURABLE INPUT - GENERIC ALARM (EA1, EA2, EAL)

It signals to the controller: EA1: generic alarm – section 1; EA2: generic alarm – section 2; EAL: generic alarm – it counts for both the sections. As soon as the digital input is activated the unit will wait for “did1” time for section 1 and “did2” time for section 2 delay before signalling the “EAL” alarm message. The outputs status don’t change. The alarm stops just after the digital input is de-activated.

1.16 CONFIGURABLE INPUT - SERIOUS ALARM MODE (BA1, BA2, BAL)

It signals to the controller: bA1: serious alarm – section 1; bA2: serious alarm – section 2; bAL: serious alarm – it counts for both the sections. As soon as the digital input is activated the unit will wait for “did1” time for section 1 and “did2” time for section 2 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.

1.17 CONFIGURABLE INPUT - START DEFROST (DF1, DF2, DEF)

It executes a defrost if there are the right conditions, respectively for: dF1: section 1; dF2: section 2; dEF: both the sections. After the defrost is finished, the normal regulation will restart only if the digital input is disabled otherwise the instrument will wait until the “Mdf1” and “MdF2” safety time is expired.

1.18 CONFIGURABLE INPUT - REMOTE ON/OFF (OF1, OF2, ONF)

This function allows to switch ON and OFF a sections of the instrument or the whole instrument according to the following setting: oF1: section 1; oF2: section 2; onF: it counts for both the sections. When the digital input is de-activated, the corresponding section restarts working.

1.19 CONFIGURABLE INPUT - ENERGY SAVING (ES)

The Energy Saving function allows to change the set point value as the result of the SET1+HES1 for section and SET2 + HES2 fro section 2. This function is enabled until the digital input is activated.

1.20 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

10. INSTALLATION AND MOUNTING

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. Thanks to the case, XLR470 model can be panel or wall mounted. See the following instructions for details.
