COMPATIBILITY.

Please, read carefully these instructions before proceeding withthe installation of the controller.Class II instrument, rear panel mounting.

This controller has been designed with compliance to:Regulations on electrical apparatus (appliance, systems and installa-tions) according to the European Community directive 73/23/EEC amend-ed by the European Comunity directive 93/68/EEC and the Regulationson the essential protection requirements in electrical apparatus EN61010-1 : 93 + A2:95.

Regulations on Electromagnetic Compatibility according to theEuropean Community directive n089/336/EEC, amended by the EuropeanCommunity directive n° 92/31/EEC, 93/68/EEC, 98/13/EECand the following regulations:Regulations on RF emissionsEN61000-6-3 : 2001 residential environmentsEN61000-6-4 : 2001 industrial environmentsRegulation on RF immunity EN61000-6-2 : 2001 industrial equipment and system

It is important to understand that it’s responsibility of the installer to ensurethe compliance of the regulations on safety requirements and EMC.This device has no user serviceable parts and requires special equipmentand specialised engineers. Therefore, a repair can be hardly carried ondirectly by the user. For this purpose, the manufacturer provides techni-cal assistance and the repair service for its Customers. Please, contact your nearest Agent for further information.All the information and warnings about safety and electromagneticcompatibility are marked with the B sign, at the side of the note.

Installation must only be carriedout by qualified personnel.

Before proceeding with the instal-lation of this controller, follow theinstructions illustrated in this man-ual and, particularly the installationprecautions marked with the Bsymbol, related to the EuropeanCommunity directive on electricalprotection and electromagneticcompatibility.

BTo prevent hands or metal touch-ing parts that may be electricallylive, the controllers must beinstalled in an enclosure and/orin a cubicle.

PRECAUTIONS B

Despite the fact that the instrumenthas been designed to work in anharsh and noisy environmental(level IV of the industrial standardIEC 801-4), it is recommended tofollow the following suggestions.

AAll the wiring must comply with thelocal regulations.

The supply wiring should be rout-ed away from the power cables.Avoid to use electromagnetic con-tactors, power Relays and highpower motors nearby.Avoid power units nearby, espe-cially if controlled in phase angle

Keep the low level sensor inputwires away from the power linesand the output cables.If this is not achievable, use shield-ed cables on the sensor input, withthe shield connected to earth.

Notes:1] Make sure that the power supply

voltage is the same indicated onthe instrument.

2] Switch on the power supply onlyafter that all the electrical con-nections have been completed.

3] In accordance with the safety reg-ulations, the power supply switchshall bring the identification of therelevant instrument. The powersupply switch shall be easilyaccessible from the operator.

4] The instrument is is PTC pro-tected. In case of failure it is sug-gested to return the instrument tothe manufacturer for repair.

5] To protect the instrument internalcircuits use:- 2 A~ T fuses for Relay outputs

6] Relay contacts are already pro-tected with varistors.Only in case of 24 V ~ induc-tive loads, use model A51-065-30D7 varistors (on request)

2.3.2 PV CONTROL INPUT B

A For L-J-K-S-T thermocouple type• Connect the wires with the

polarity as shown• Use always compensation cable

of the correct type for the ther-mocouple used

• The shield, if present, must beconnected to a proper earth.

B For Pt100 resistance thermometer

• If a 3 wires system is used, usealways cables of the same diam-eter (1mm2 min.) (line 20 Ω/leadmaximum resistance)

• When using a 2 wires system, usealways cables of the same diam-eter (1,5mm2 min.) and put ajumper between terminals 5 and 6

C For ∆T (2x RTD Pt100) SpecialAWhen the distance between

the controller and the sensoris 15 mt. using a cable of 1.5mm2 diameter, produces anerror on the measure of 1°C(1°F).

R1 + R2 must be <320Ω

Derivativetime

It is the time required by the proportionalterm P to repeat the output provided bythe derivative term D. When Off thederivative term is not included in thecontrol algorithm.

Control output cycle time Cycle time cool

It’s the cycle time of the logic con-trol output. The PID time propor-tional control output is providedthrough the pulse width modula-tion of the digital waveform.

By a sole PID control algorithm, thecontroller handles two different out-puts, one of these performs theHeat action, the other one the Coolaction.It is possible to overlap the out-puts. The dead band parameter #d.bnd,is the zone where it is possible toseparate or overlap the Heat andCool actions.

The Cool action can be adjustedusing the relative cool gain para-meter #r.C.Ga.

To limit the Heat and Cool outputsthe parameters #0p. H and #0p.HCcan be used.

When there is an overlap, the dis-played output # OUt shows thealgebric sum of the Heat and Cooloutputs.

5 AUTOMATICTUNING

Two tuning methods are provided:• Initial one shot Fuzzy-tuning • Continuous, self learning

Adaptive Tuning

The Fuzzy-Tuning allows the calcu-lation of the optimal PID terms para-meters, monitoring the response ofthe process to disturbances.The controller provides 2 types of“one shot” tuning algorithm, thatare selected automatically accord-ing to the process condition whenthe operation is started.Step responseThis type is selected when, at thestart of the autotune operation, thePV is far from the Setpoint of morethan 5% of the span.This method has the big advantageof fast calculation, with a reasonableaccuracy in the term calculation.Natural frequencyThis type is selected when the PV isclose to the SP Setpoint.This method has the advantage of

a better accuracy in the term cal-culation with a reasonable speedcalculation.The Fuzzy Tuning determinesautomatically the best method touse to calculate the PID term,according the process conditions.

The green led blinking goes onwhen the Fuzzy Tuning is inprogress. At the end of this opera-tion, the calculated PID terms para-meter are stored and used by thecontrol algorithm and the controllergoes back to the operator mode.The green led becomes off.

39

5 - Automatic tuning

The self-learning Adaptive Tuningis not intrusive. It doesn’t affect theprocess, at all, during the phase ofcalculation of the optimal termsparameters.

It is particularly suitable for con-trolling process whose controlcharacteristics change withtime or are not linear in relationto the Setpoint values.It doesn’t require any operation bythe user. It is simple and works fine:it samples continuously theprocess response to the variousperturbations, determining the fre-quency and the amplitude of thesignals. On the basis of this dataand their statistical values, storedin the instrument, it modifies auto-matically the PID term parameters.It is the ideal for all applicationswhere it is required to change con-

6 SPECIAL FUNCTIONS

Two special functions are available:6.1 Safety average OP on

sensor break6.2 Digital remote setpoint control

(Setpoint raise/lower + Stand-by Setpoint)

This function is available only if theindex E of the model code (seepage 17) engages the value 7 or 8.The averages comes effected, fil-tering the output with a first orderfilter with around 50 seconds ofconstant of time. Such filter isactive in a continuous way whenthe input is in conditions of normaloperation; in conditions of outscale the refresh of the filter comesjammed and the reached valuebecomes the output. The #Sa.OP parameter (see pages28,32) doesn't appear when theoption is enabled.

This function is available only if theindex E of the product code of themodel (see page 17) engages thevalue 6 or 8 and the digital inputoption (C index= 9) is present.The parameter of configuration#Il...fn (see page 35) allows to setthe Cust value that enable thefunction.Connecting to the digital input anoutput of the APG2- DRSPC card(see manual N. M.I.U. DRSPC J30-628-1ADRSPC) it is possible:

1. To increase the Setpoint of astep

2. To decrease the Setpoint of thesame step

3. To select the Stand-by Setpoint#S.P. 2 (see page 27)

The value of the step has givenfrom the # .S.P.In parameter (seepages 27,30).
