or panel installation (IR33), with IP65 index o protection, and or DIN railmounting (DN33). To simpliy wiring, all the models are ftted with plug-interminals. The controllers can be connected via a network to supervisoryand telemaintenance systems.The accessories available include: computer-based programming tool;

remote control or operation and programming; programming key, with battery; programming key, with 30 Vac power supply; RS485 serial card; RS485 serial card, with possibility o reversing the Rx-Tx terminals; module or converting the PWM signal to a 0 to 10 Vdc or 4 to 0 mA

analogue signal; module or converting the PWM signal to an ON/OFF relay signal.

IR33-DN33 Universale is a series o controllers designed or controllingthe main physical values (temperature, pressure, humidity) -conditioning,rerigeration and heating units. There are two product lines: the frstor two temperature probes only (NTC, NTC-HT, PTC, PT1000) and thesecond or two temperature probes with a wider range (NTC, NTC-HT,PTC, PT100, PT1000, J/K thermocouples), or pressure and humidity

transducers or or general signal transmitters (0 to 1 V, 0 to 10 V, -0.5 to1.3V voltage inputs, 0 to 5 V ratiometric inputs or 0 to 0 mA, 4 to 0 mAcurrent inputs). See the table below. The models also dier according tothe type o power supply (115 to 30 Vac or 1 to 4 Vac, 1 to 30 Vdcor controllers with temperature inputs only and 115 to 30 Vac or 4Vac/Vdc or controllers with universal inputs) and which based on themodel may be one, two or our relays, our PWM outputs or controllingexternal solid state relays (SSR), one or two relays plus one or two 0 to 10Vdc analogue outputs (AO) respectively. The type o control can be setas ON/OFF (proportional) or proportional, integral and derivative (PID).A second probe can be connected or dierential control or reecooling/reeheating, or or compensation based on the outside temperature.Alternatively, a second control cycle can be activated with independentset point, dierential and dedicated outputs.

1.2 Functions and main characteristics

The IR33/DN33 controllers eature two main types o operation: directand reverse, based on the value measured. In direct operation, theoutput is activated i the value measured exceeds the set point plusa dierential, and thus aims to keep the value below a certain level(typically used in rerigeration systems). Vice-versa, in reverse operationthe output is activated when the temperature alls below the set pointplus a dierential (typically used in heating systems).

There are nine preset operating modes in which the installer can choosethe set point and the activation dierential.In special operating mode, the exact activation point and deactivationand the control logic, direct or reverse, can both be set, guaranteeingsignifcant exibility. Finally, automatic cycles can be programmed, calledoperating cycles, used or example in processes where the temperaturemust remain above a certain value or a minimum time (pasteurisation). Anoperating cycle is defned by fve time intervals in which the temperaturemust reach a certain set point. The operating cycle is activated on thekeypad, via digital input or automatically on the models with RTC. Onall models, it runs or the set time , thanks to the internal timer. Theremote control, an accessory available or all the controllers, has the samebuttons as the controller interace, and in addition can directly display themost requently used parameters. Based on the model o controller, theoutput activated may be a relay, a PWM signal or solid state relays (SSR)

or a voltage that increases linearly rom 0 to 10 Vdc. The PWM output canalso be converted, using the ollowing modules:

CONV0/10A0: conversion rom PWM output or SSR to a linear 0 to 10Vdc or 4 to 0 mA analogue signal;

CONONOFF0: conversion rom PWM output or SSR to an ON/OFF relayoutput.

Starting frmware revision .0, IR33 Universale can manage two circuitswith independent PID control. New sotware unctions have also beenintroduced, such as speed-up, cut-o and orcing the output romdigital input, which can be selected or each output. See the paragraphSotware revisions and the chapter Functions.

Below is a description o the accessories or the IR33/DN33 Universal:

ComTool programming tool

(downloadable rom http://ksa.carel.com)With this useul tool, the controller can be programmed rom any PC,saving the dierent confgurations to fles that can be loaded during thefnal programming stage, creating custom sets o parameters or asterprogramming and setting dierent user profles with access protectedby password.The PC must be ftted with the USB/RS485 converter (CVSTDUMOR0) andthe RS485 serial interace (IROPZ48500).

2.6 Connection diagrams

2.6.1Connection to the CONV0/10VA0 and CONVONOFF0 modules (accessories)The CONV0/10AVA0 and CONVONOFF0 modules convert a PWM output or SSR to a 0 to 10 Vdc analogue output and ON/OFF relay output respectively.Below is an example o an application that uses model DN33A7LR0. Note that the same controller can thus have 3 dierent types o outputs. I only the0 to 10 Vdc analogue output and the relay output are required, models DN33E7LR0 or DN33E9MR0 can be used; the wiring diagram is shown below.

TEMPERATURE INPUTS

On models B and E with direct or alternating current power supply,the reerence (G0) or the 0 to 10 Vdc output and the power supply

reerence cannot be in common.

I the actuators connected to the analogue outputs require, theearth connection (PE) is perormed making sure that this is on G0 o

the ,outputs as shown in the fgure.

For models DN33x(B, E)7LR0 and IR33x(B, E)7LR0 the diagramshown must be adhered to, otherwise the instrument may be

damaged irreversibly.

UNIVERSAL INPUTS

For models B and E with DC or AC power supply, the reerence (G0)or the 0 to 10 Vdc output and power supply reerence may be incommon, make sure the polarity is observed or 4 V power supply (G,G0). This allows just one transormer to be used.

2.7 Installation

To install the controller, proceed as ollows, with reerence to the wiringdiagrams:

1. connect the probes and power supply: the probes can be installedup to a maximum distance o 100 m rom the controller, usingshielded cables with a minimum cross-section o 1 mm2. To improveimmunity to disturbance, use probes with shielded cables (connectonly one end o the shield to the earth on the electrical panel).

. Program the controller: see the chapter User interace.3. Connect the actuators: the actuators should only be connected

ater having programmed the controller. Careully check themaximum relay capacities, indicated in technical specifcations.

4. Serial network connection: i connection to the supervisor networkis available using the relevant serial cards (IROPZ485*0 or IR33and IROPZSER30 or DN33), make sure the system is earthed. Oncontrollers with 0 to 10 Vdc analogue outputs (models B and E) makesure there is only one earth connection. Specifcally, the secondaryo the transormers that supply the controllers must not be earthed(temperature only models). I connection to a transormer withearthed secondary winding is required, an insulating transormermust be installed in between. A series o controllers can be connectedto the same insulating transormer, nevertheless it is recommended

to use a separate insulating transormer or each controller.Case 1: a series o controllers connected in a network powered by thesame transormer (G0 not earthed). Typical application or multiplecontrollers connected inside the same electrical panel

Avoid installing the controller in environments with the ollowingcharacteristics:

relative humidity over 90% non-condensing; heavy vibrations or knocks; exposure to continuous jets o water; exposure to aggressive and polluting atmospheric agents (e.g.: sulphur

and ammonia gases, saline mist, smoke) which may cause corrosionand/or oxidation;

high magnetic and/or radio requency intererence (e.g. do not install

near transmitting antennas); exposure to direct sunlight and atmospheric agents in general.

The ollowing warnings must be observed when connecting thecontrollers:

incorrect connection o the power supply may seriously damage thesystem;

use cable ends that are suitable or the terminals. Loosen every screwand ft the cable end, next tighten the screws and gently pull thecables to check their tightness;

separate as much as possible (at least 3 cm) the probe and digitalinput cables rom inductive loads and power cables, to avoid anyelectromagnetic disturbance. Never lay power and probe cables in thesame cable conduits (including those or the electrical panels);

do not install the probe cables in the immediate vicinity o power

devices (contactors, circuit breakers or the like). Reduce the length othe sensor cables as much as possible, and avoid spirals around powerdevices;

avoid supplying the controller directly rom the main panel powersupply i also supplying power to other devices, such as contactors,solenoid valves, etc., which require another transormer.

IR33 is not a device that guarantees electrical saety, but rathersuitable operation: to prevent short-circuits or overloads rom

causing hazards, the customer must install appropriate electromechanicalprotection devices on the lines in question (uses or the like).

system being managed: Starting rom revision FW .0 two PID controlcycles can be set on two independent circuits;

I the controller is ftted with RTC (clock), set the current time and theon and o times;

Set the standard display; Set the probe type parameter based on the probe available and the

type o control (NTC, NTC-HT, PTC, PT1000, J/K thermocouple, voltage/

current input); Set the type o control: ON/OFF (proportional) or proportional, integral,derivative (PID);

I used as a thermostat, set the unit o measure or the probes (C or F),see paragraph 5.1;

Any operating cycles are programmed correctly; The protection unctions (delay at start-up, rotation, minimum on and

o times or the outputs) are active; The remote control enabling code is set, i a series o controllers are

installed in the same system; I the CONV0/10A0 module is connected, the cycle time is set to the

minimum (c1=0. s); The special mode is set in the correct sequence, i.e. frst parameter c0 is

set, and then parameter c33 (see the chapter on Functions).

5. FUNCTIONS

In the tables, the parameters that are repeated highlight thedierences in settings between the models with universal inputs

and the models with temperature inputs only.

5.1 Temperature unit o measure

On IR33 Universale the temperature unit o measure can be changedrom degrees Celsius to degrees Fahrenheit using parameter c18.

Par. Description Def Min Max UOMc18 Temperature unit o measure

0=C; 1=F0 0 1 -

Tab. 5.a

The models with universal inputs can be connected to PT100 or PT1000probes and thermocouples, and operate with temperatures rom -199Cto 800C, consequently the parameters corresponding to the minimumand maximum limits o the set point are dierent. See the table below.The unction works as ollows:1. in degrees Celsius the settable temperature range is -199T800C;. in degrees Fahrenheit the settable temperature range is -199T800F.

Due to the conversion using the ormula:T(F)=T(C) x1.8 + 3

the settable temperature range in degrees Celsius is wider than indegrees Fahrenheit.

I the display is showing the reading o probe 1 or in the range between-199C and -18C or between 46C and 800C, and the unit is set todegrees Fahrenheit, the error E01 or E0 will be shown;

I the controller is working in degrees Celsius and the temperature set pointis set over 46C or below -18C, i then switching to degrees Fahrenheitthe set point will be limited to 800F and -199F respectively.

When a probe with current/voltage signal is selected, the unit omeasure must be let at C (C18=0).

Parameter c13 defnes the type o probe 1 (B1) and any probe (B).For controllers with universal inputs, the corresponding selectionsare highlighted in the table. Parameters P14 and P15, or probe 1 andprobe respectively, are used to correct the temperature measured bythe probes indicated on the display, using an oset: the value assignedto these parameters is in act added to (positive value) or subtractedrom (negative value) the temperature measured by the probes. Whenpressing Set, ater having entered the value, the display does not showthe parameter, but rather immediately shows the new value o the probereading being calibrated. This means the result o the setting can bechecked immediately and any adjustments made as a consequence.Press Set again to access the parameter code and save the value. Forprobes with current/voltage signals, parameters c15, c16 or probe 1 andd15, d16 or probe are used to scale the probe output signal. The valueo parameters P14, P15 is added ater this operation.

Consequently, 0 V will be as displayed 30 and 10V will be displayed as 90.These are also the values used or control.

Parameter c17 defnes the coe cient used to stabilise the temperaturereading. Low values assigned to this parameter allow a prompt responseo the sensor to temperature variations, but the reading becomes moresensitive to disturbance. High values slow down the response, butguarantee greater immunity to disturbance, that is, a more stable andmore precise reading.

5.3 Standard operating modes (parameters

St1,St2,c0,P1,P2,P3)The controller can operate in 9 dierent modes, selected by parameterc0. The basic modes are direct and reverse. In direct mode, the outputis activated i the value measured is greater than the set point plus adierential. In reverse mode the output is activated i the temperature isless than the set point plus a dierential. The other modes are a combinationo these, with possibility o set points (St1 & St) and dierentials (P1 &P) based on the mode, direct or reverse, or the status o digital input1. Other modes include dead zone (P3), PWM and alarm. The numbero outputs activated depends on the model (V/W/Z=1,,4 relay outputs,A=4 SSR outputs, B/E=1/ analogue outputs and 1/ relay outputs).Selecting the correct operating mode is the frst action to be perormed

To be able to set c0, the value o c33 must be 0. I c33=1, changing c0has no eect.

For the mode set to become immediately operational, the controllerneeds to be switched o an on again. Otherwise correct operation is

not guaranteed.The meaning o parameters P1 & P changes according to theoperating mode selected. Fore example, in modes 1 & the

dierential is always P1. P, on the other hand, is the reverse dierentialin mode 6 and the direct dierential in mode 9.

5.3.1 Mode 1:Direct c0=1In direct operation the controller ensures the value being controlled (inthis case the temperature) does not exceed the set point (St1). I it does,the outputs are activated in sequence. The activation o the outputs isdistributed equally across the dierential (P1). When the value measuredis greater than or equal to St1+P1 (in proportional only operation), all theoutputs are activated. Similarly, i the value measured starts alling, theoutputs are deactivated in sequence. When reaching St1, all the outputsare deactivated.

5.3.2 Mode 2: Reverse c0=2 (Deault)Reverse operation is similar to direct operation, however the outputsare activated when the value being controlled decreases, starting romthe set point (St1). When the value measured is less than or equal toSt1-P1 (in proportional only operation), all the outputs are activated.Similarly, i the value measured starts rising, the outputs are deactivatedin sequence. When reaching St1, all the outputs are deactivated.

When the controller only has 1 output, it works in reverse mode withdead zone.

PWM mode should not be used with compressors or other actuatorswhose reliability may be aected by starting/stopping too requently.

For relay outputs, parameter c1 should not be set too low, so as to notcompromise the lie o the component..

5.3.5 Mode 5:Alarm c0=5In mode 5, one or more outputs are activated to signal a probedisconnected or short-circuited alarm or a high or low temperature alarm.Models V and W only have one alarm relay, while model Z has two: relay3 is activated or general alarms and or the low temperature alarm, relays4 is activated or general alarms and or the high temperature alarm. Theactivation o the alarm relay is cumulative to the other signals in the otheroperating modes, that is, alarm code on the display and audible signal.For models W & Z, the relays not used to signal the alarms are used or

control, as or mode 3 and shown the ollowing diagrams. This operationmode is not suitable or the models B and E.The parameters corresponding to probe become active withindependent operation (c19=7).

5.3.3 Mode 3:Dead zone c0=3The aim o this control mode is to bring the measured value within aninterval around the set point (St1), called the dead zone. The extent o thedead zone depends on the value o parameter P3. Inside the dead zone, thecontroller does not activate any outputs, while outside it works in directmode when the temperature is increasing and in reverse mode when itis decreasing. According to the model used, there may be one or moreoutputs in direct and reverse modes. These are activated or deactivatedone at a time, as already described or modes 1 & , according to the value

measured and the settings o St1, P1 or reverse control and P or directcontrol.

When the controller only has 1 output, it works in reverse mode with

dead zone.

5.3.4 Mode 4: PWM c0=4The control logic in PWM mode uses the dead zone, with the outputsactivated based on pulse width modulation (PWM). The output isactivated in a period equal to the value o parameter c1 or a variabletime, calculated as a percentage; the ON time is proportional to the valuemeasured by B1 inside the dierential (P1 or reverse control and P ordirect control). For small deviations, the output will be activated or ashort time. When exceeding the dierential, the output will be alwayson (100% ON). PWM operation thus allows proportional control oactuators with typically ON/OFF operation (e.g. electric heaters), so as toimprove temperature control. PWM operation can also be used to gavea modulating 0 to 10 Vdc or 4 to 0 mA control signal on IR33 (DN33)

Universal models A, D with outputs or controlling solid state relays (SSR).In this case, the accessory code CONV0/10A0 needs to be connected toconvert the signal. In PWM operation, the direct/reverse icon ashes.
