PRECAUTIONS BDespite the fact that the instru-ment has been designed to workin an harsh and noisy environ-mental (level IV of the industrialstandard IEC 801-4), it is recom-mended to follow the followingsuggestions.

AAll the wiring must comply withthe local regulations. The supply wiring should be rout-ed away from the power cables.Avoid to use electromagneticcontactors, power Relays andhigh power 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, useshielded cables on the sensorinput, with the shield connectedto earth.

Conduit for supply and output cables

2.3 EXAMPLE OF WIRING DIAGRAM (HEAT / COOL CONTROL) B

Notes:1] Make sure that the power supply voltage is

the same indicated on the instrument.2] Switch on the power supply only after that

all the electrical connections have beencompleted.

3] In accordance with the safety regulations,the power supply switch shall bring theidentification of the relevant instrument. Thepower supply switch shall be easily acces-sible from the operator.

4] The instrument is is PTC protected. In caseof failure it is suggested to return the instru-ment to the manufacturer for repair.

5] To protect the instrument internal circuitsuse:- 2 A~ T fuse for Relay outputs (220 VAC)- 4 A~ T fuse for Relay outputs (110 VAC)- 1 A~ T fuse for Triac outputs

6] Relay contacts are already protected withvaristors.Only in case of 24 V ~ inductive loads,use model A51-065-30D7 varistors (onrequest)

4.4.2.1 AUTOMATIC TUNE

The Fuzzy-Tuning determinesautomatically the best PID termwith respect to the processbehaviour.

The controller provides 2 types of“one shot” tuning algorithm, thatare selected automatically accord-ing to the process condition whenthe operation is started.

#tune This type is selected when, atthe start of the autotune oper-ation, the PV is far from theSetpoint of more than 5% of thespan. This method has the bigadvantage of fast calculation,with a reasonable accuracy inthe term calculation.

This type is selected when the PVis close to the SP Setpoint.This method has the advantageof a better accuracy in the termcalculation with a reasonablespeed calculation.

The Fuzzy Tuning determinesautomatically the best methodto use to calculate the PIDterm, according the processconditions.

4.4.2.2 HEAT / COOL CONTROL

By a sole PID control algorithm, the con-troller handles two different outputs, oneof these performs the Heat action, the otherone the Cool action.It is possible to overlap the outputs.

The dead band parameter #d.bnd, is the zonewhere it is possible to separate or overlapthe Heat and Cool actions.

The Cool action can be adjusted using therelative cool gain parameter #r.C.Ga.

To limit the Heat and Cool outputs the para-meters #0p. H and #0p.HC can be used.

When there is an overlap, the displayed out-put # OUt shows the algebric sum of theHeat and Cool outputs.

4.4.4 TIMER AND START-UP MENU (OPTION)

To improve the instrument per-formances and to reduce thewiring and installation costs,two special functions are avail-able:4.4.4.1 Start-up4.4.4.2 Timer

In order to have the above func-tions the product code digitemust be 2 (see page 19).

For example: Q3 3100-2000To select these functions use theparameter: (see page 43).

A Selecting Timer or Start-up, the Soft-start functionis disabled, therefore theparameters #st.Op and#st.tM will not be shown(see page 29).

#t.Mod

By means of this function it ispossible to manipulate the con-trol output when the controlleris switched on.

To config-ure Start-up func-tion theparameter

“Timer/Start-up operating mode”must be set to # 1 (see page43).Three parameters are associat-ed to the Start-up function.

2nd “Hold” - The process variableis maintained to the Start-upSetpoint for the time fixed bythe parameter #t.h.s.U

3rd “Off” - When the #t.h.s.Utime is elapsed the processvariable is maintained to theworking Setpoint.

Whether the process variable,for any reason (e.g. loadchange), decreases at a valuelower than ( #s.p.sU - 40 digits),the Start-up function starts againfrom the “Limy” phase.

#Op.Hs

42

4 - Operations

When the Start-up is in Holdphase, if the local Setpointbecomes lower than the Start-up Setpoint or if the operatingmode changes to manual, theStart-up function passes to the“Off” phase.

There are two possibilities:A Start-up Setpoint #sp.sU

lower than the localSetpoint.The “Hold” phase startswhen the process variablePV achieves the #sp.sU(with a tolerance of 1 digit).

B Start-up Setpoint #sp.sUgreater than or equal tothe local Setpoint.

When the process variable PVachieves the local Setpoint (with atolerance of 1 digit), the Start-upfunction passes directly to the “Off”phase.

If, at the controller power-on, theprocess variable PV is greater thanthe lowest between the #sp.sUand the working Setpoint , thenext phase (“Hold” or “Off”) willbe executed instead of the “Limy”phase.

During the “Limy” and “Hold”phases the Ö led is on.

With CT option, it is possible todisplay the load current and setan alarm threshold.

The setting can be done bymeans the 8 or 9 configurationindex of the codes O, P or Q(see pages 21 and 22).It is possible to set one of thealarms (see pages 21 and 22) tohave an alarm when, during theON time of the time proportion-al output, the load current is lessthen the specified threshold(index 8), or during the OFFtime there is a value > 3% of fullscale load current.

The alarm condition must belonger than 120 ms to set thealarm.By the parameter:

CT primary high rangeOFF/ 1…200A

the load current display can beadapted to the transformercharacteristics (OFF means dis-abled).

During the OFF time the para-meter #t.Cur latches the last ontime current value.

A function is assigned, throughthe configuration procedure toeach IL1, IL2 and IL3 digitalinput. (see the parameters set-ting at tab. 1 at page 31).The configured function is acti-vated when the digital input (freevoltage contact or open collec-tor output) is in the On state(closed). It is deactivated by set-ting the input to the Off state(open).The activation of the functionthrough the digital input has thehighest priority than through thekeypad or through the serialcommunication.

7 PROGRAMMED SETPOINT

INTRODUCTIONThe controller supplied with theSetpoint programmer option (mod.Q3-3… &) offers the functionali-ty to define, store, display and exe-cute a program consisting in theSetpoint profile in time.

MAIN CHARACTERISTICS• 1 program, 8 segments/program• start, stop, hold etc, com-

mands from the keypad• time base in seconds, min-

utes or hours• continuous or up to 1…9999

time cycling of the program• 1 OP3 digital output with the

state profile defined by theprogram

• setting of the maximumallowed deviation from theSetpoint

The program consists of asequence of segments.

For each segment, it is specified:• the Setpoint

to reach#s.p.

• the duration of the segment#t.i.

• the state of the OP3 output

The program consists of:• 1 initial segment named O• 1 end segment named f• 1…6 normal segments

alvayspresent

Initial segment - 0Its main purpose is to define thevalue the process variable hasto maintain before starting theprogram.

End segment - FIts main purpose is to define thevalue the process variable hasto maintain at the end of the pro-gram and until further changesof Setpoint.

Normal segments - ===These segments build up theprofile program. There are 3types of segments:
