PARRANGEDESCRIPTION

SCL

1°C;

2°C;

°F

Readout scale (see table of input specifications)

Caution: upon changing the SCL value, it is then absolutely necessary to reconfigure the param-

eters relevant to the absolute and relative temperatures (SPL, SPH, 1SP, 1HY etc..)

SPL

-50°...SPHMinimum limit for 1SP setting

SPH

SPL...150°Maximum limit for 1SP setting.

1SP

SPL... SPHSetpoint (value to be maintained in the room).

1CM

HY; PIDControl mode.

With 1CM=HY you select control with hysteresis: parameters 1HY, 1T0 and 1T1 are used.

With 1CM=PID you select a Proportional-Integral-Derivative control mode: parameters 1PB, 1IT,

1DT, 1AR, 1CT will be used

1CH

REF; HEARefrigerating (REF) or Heating (HEA) control mode.

1CM=HY

1HY

0...19.9°OFF/ON thermostat differential. With 1HY=0 the output is always off.

1T0

0...30minMinimum off time.

Afteroutput1 has beenturnedoff,itremainsinactivefor 1T0 minutesregardless of the

temperature value measured.

1T1

0...30minMinimum on time. (the following parameter will be 1PF).

Afteroutput 1 has beenturnedon,itremainsactivefor 1T1 minutesregardless of the temperature

value measured.

1CM=PID

1PB

0...19.9°Proportional bandwidth.

Temperaturecontrol takesplace bychangingthe

ON time of the output: the closer the temperature

to the setpoint, the less time of activation. Asmall

proportionalbandincreasesthe promptness of

response of the system to temperature variations,

buttends to makeitless stable.Apurely

proportionalcontrol stabilisesthe temperature

withinthe proportionalbandbutdoes not cancel

the deviation from setpoint.

With 1PB=0 the output is always off.

1IT

0...999sIntegral action time.

The steady-state error is cancelled by inserting an

integralaction. The integralactiontime,determines

the speed with which the steady-state temperature

isachieved,buta highspeed (1ITlow)maybethe

causeof overshootand instabilityinthe response.

With 1IT=0 the integral control is disabled.

1DT

0...999sDerivative action time.

Response overshoot may be reduced by inserting

a derivative Action. A high derivative action (1DT

high)makesthe systemverysensitiveto small

temperaturevariations and causesinstability. With

1DT=0 the derivative control is disabled.

1AR

0...100%Reset of integral action time referred to 1PB

Decreasingthe parameter 1AR reducesthe integralcontrol actionzone,and consequentlythe

overshoot (see figure on paragraph 1IT).

1CT

1...255sCycle time.

It’s the period in which the output ON time changes. The quicker the system to be controlled

reacts to temperature variations, the smaller the cycle time must be, in order to obtain higher

temperature stability and less sensitivity to load variations.

1PF

ON/OFFOutput state in case of probe failure.

OAU

NON;

THR;

AL0;

AL1

AUX output operation.

NON : output disabled (always off). (the next parameter will be ATM)

THR: output programmed for second thermostat control (the next parameter will be 2SM).

AL1: contacts make when an alarm condition occurs (the next parameter will be ATM).

DISPLAY

During normal operation, the display shows either the temperature measured or one of the following indications:

Controller in stand-byController in autotuning

ProbeT1 overrange or failureIn tuning: timeout1 error

Room high temperature alarmIn tuning: timeout2 error

Room low temperature alarm In tuning: overrange error

MENU INFO

The information available in this menu is:

Maximum temperature recordedKeypad state lock

Minimum temperature recorded

Access to menu and information displayed.

Press and immediately release button ■

.

With button ■ or select the data to be displayed.

Press button ■ to display value.

To exit from the menu, press button ■ or wait for 10 seconds.

Reset of THI, TLO recordings

With button ■ or select the data to be reset.

Display the value with button ■.

While keeping button ■ pressed, use button .

CHANNEL 1 SETPOINT (display and modification of desired temperature value)

Press and release button ■ : theLED L1 blinks, the display shows 1SP for 1 second and then the setpoint associated value.

Press buttons ■or to set the desiredvalue(adjustment iswithin theminimumSPLand maximum SPHlimit).

To store the new value press button ■, or wait for 10 seconds.

To go back to normal mode without saving the new value, press ■.

CHANNEL 2 SETPOINT

Withthe auxiliaryoutputset as thermostat control (■OAU=THR),it’s possibleto modifysetpoint2 duringthe normal operation

of the controller.

Press and release button ■:the LEDL2blinks,the displayshows2SP for 1 second ifsetpoint2 isan absolutethreshold

(2SM=ABS),alternativelythe displayshows2DF,ifsetpoint2 isa threshold relativeto setpoint1 (2SM=REL),then the value

associated to the parameter appears.

Press buttons ■ or to set the desired value.

To store the new value press button ■ or wait for 10 seconds.

To go back to normal mode without saving the new value, press ■.

STAND-BY

Button, whenpressed for3 seconds, allows the controller to beput on a standbyor output control to beresumed(with SB=YES only).

KEYPAD LOCK

The keypad lock avoids undesired, potentially dangerous operations, which might be attempted when the controllers is operating

in a publicplace. In the INFO menu, set parameter LOC=YES to inhibit all functionsof the buttons. To resume normal operation

of keypad, adjust setting so that LOC=NO.

CONTROLLER AUTOTUNING IN PID MODE

Before starting

In the setup mode (see configuration parameters): set 1CM=PID; make sure that 1CH matches the desired operation mode

(1CH=REF for refrigerating control, 1CH=HEA for heating control); then adjust setpoint 1SP at the desired value.

Start autotuning

During normal operation,keepbuttons + pressed for 3seconds. 1CT blinks on the display. With + or set the cycle

timeinorder to definethe dynamicof the process to becontrolled. To abort the autotuning function, press ; to start autotuning

press

+ or wait for 30 seconds.

During autotuning

Duringthe entireautotuningphase,the displayalternates TUNwiththe actualtemperaturemeasured.In case of powerfailure,

whenpowerisresumed,after the initialautotestphase,the controller resumes the autotuningfunction.To abort the autotuning,

withoutmodifyingthe previouscontrol parameters,keepbutton

pressed for 3 seconds. After the autotuning has taken place

successfully, the controller updates the control parameters and start to control.

Errors

If the autotuning function failed, the display shows an error code:

E1 timeout1 error: the controller could not bring the temperature within the proportional band. Increase ■1SPin case of heating

control, vice versa, decrease 1SP in case of refrigerating control and re-start the process.

E2 timeout2 error: the autotuning has not ended within the maximum time allowed (1000 cycle times). Re-start the autotuning ■

process and set a longer cycle time 1CT.

E3temperatureoverrange:check that the error was not causedbya probemalfunction, then decrease ■1SPin case of heating

control, vice versa increase 1SP in case of refrigerating control and then re-start the process.

To eliminate the error indication and return to the normal mode, press button ■

.

Control improvement

To reduce overshoot, reduce the integral action reset ■1AR

To increase the responsespeed of thesystem, reduce theproportionalband ■1PB. Caution: doing thismakes thesystem less stable.

To reduce swings in steady-state temperature, increase the integralactiontime ■1IT; systemstabilityisthusincreased,although

its response speed is decreased.

To increase the speed of response to the variations in temperature, increase the derivative action time ■1DT. Caution:a high

value makes the system sensitive to small variations and it may be a source of instability.

RECALIBRATION

Have a precision reference thermometer or a calibrator to hand. Ensure that ■OS1=0 and SIM=0.

Switch the controller off then on again.■

During the auto-test phase, press buttons ■ + and keep them pressed till the controller shows 0AD.

Withbuttons ■ and select 0AD or SAD: 0ADallows a calibration of 0,inserting a constant correctionover the whole scale

of measurement. SAD allows a calibration of the top part of the measurement scale with a proportional correction between the

calibration point and 0.

Press ■

to display the value and then use + or to make the read value coincide with the value measured by the

reference instrument.

Exit from calibration by pressing button ■

.

OPERATION

The L03B--controller,size71x98x61 mm (WxHxD),is to besecured to a DIN railinsucha position as to ensure that no liquid ■

infiltrates causing serious damage and compromising safety;

Makesurethat electricalconnectionscomplywiththe paragraph “wiringdiagrams”.To reduce the effects of electromagnetic ■

disturbance, keep the sensor and signal cables well separate from the power wires.

Place the probeT1 inside the room in a point that truly represents the temperature of the stored product.■
