CONFIGURATION PARAMETERSTo get access to the parameter configuration menu, press button■ + for 5 seconds.With button■ or select the parameter to be modified.Press button■ to display the value.By keeping button■ pressed, use button or to set the desired value.When button■ is released, the newly programmed value is stored and the following parameter is displayed.To exit from the setup, press button■ or wait for 30 seconds.PAR RANGE DESCRIPTIONSCL 1°C;2°C;°FReadout 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°...SPH Minimum limit for 1SP settingSPH SPL...150° Maximum limit for 1SP setting.1SP SPL... SPH Setpoint (value to be maintained in the room).1CM HY; PID Control 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 used1CH REF; HEA Refrigerating (REF) or Heating (HEA) control mode.1CM=HY1HY 0...19.9° OFF/ON thermostat differential. With 1HY=0 the output is always off.1T0 0...30min Minimum off time.After output 1 has been turned off, it remains inactive for 1T0 minutes regardless of thetemperature value measured.1T1 0...30min Minimum on time. (the following parameter will be 1PF).After output 1 has been turned on, it remains active for 1T1 minutes regardless of the temperaturevalue measured.1CM=PID1PB 0...19.9° Proportional bandwidth.Temperature control takes place by changing theON time of the output: the closer the temperatureto the setpoint, the less time of activation. A smallproportional band increases the promptness ofresponse of the system to temperature variations,but tends to make it less stable. A purelyproportional control stabilises the temperaturewithin the proportional band but does not cancelthe deviation from setpoint.With 1PB=0 the output is always off.1IT 0...999s Integral action time.The steady-state error is cancelled by inserting anintegral action. The integral action time, determinesthe speed with which the steady-state temperatureis achieved, but a high speed (1IT low) may be thecause of overshoot and instability in the response.With 1IT=0 the integral control is disabled.1DT 0...999s Derivative action time.Response overshoot may be reduced by insertinga derivative Action. A high derivative action (1DThigh) makes the system very sensitive to smalltemperature variations and causes instability. With1DT=0 the derivative control is disabled.1AR 0...100% Reset of integral action time referred to 1PBDecreasing the parameter 1AR reduces the integral control action zone, and consequently theovershoot (see figure on paragraph 1IT).1CT 1...255s Cycle time.It’s the period in which the output ON time changes. The quicker the system to be controlledreacts to temperature variations, the smaller the cycle time must be, in order to obtain highertemperature stability and less sensitivity to load variations.1PF ON/OFF Output state in case of probe failure.OAU NON;THR;AL0;AL1AUX 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).AL0: contacts open when an alarm condition occurs (the next parameter will be ATM).AL1: contacts make when an alarm condition occurs (the next parameter will be ATM).OAU=THR2SM ABS;RELSetpoint 2 mode.Channel 2 setpoint may be absolute (2SM=ABS), or a differential relative to setpoint 1 (2SM=REL)2SM=ABS2SP SPL...SPH Auxiliary output switchover temperature (the next parameter will be 2CH)2SM=REL2DF -19.9...19.9° Temperature differential relative to 1SP.

In the INFO menu, set parameter LOC=YES to inhibit all functions of the buttons. To resume normal operationof keypad, adjust setting so that LOC=NO.CONTROLLER AUTOTUNING IN PID MODEBefore startingIn 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 autotuningDuring normal operation, keep buttons + pressed for 3 seconds. 1CT blinks on the display. With + or set the cycletime in order to define the dynamic of the process to be controlled. To abort the autotuning function, press ; to start autotuningpress + or wait for 30 seconds.During autotuningDuring the entire autotuning phase, the display alternates TUN with the actual temperature measured. In case of power failure,when power is resumed, after the initial autotest phase, the controller resumes the autotuning function. To abort the autotuning,without modifying the previous control parameters, keep button pressed for 3 seconds. After the autotuning has taken placesuccessfully, the controller updates the control parameters and start to control.ErrorsIf 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■ 1SP in case of heatingcontrol, 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.E3 temperature overrange: check that the error was not caused by a probe malfunction, then decrease■ 1SP in case of heatingcontrol, 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 improvementTo reduce overshoot, reduce the integral action reset■ 1ARTo increase the response speed of the system, reduce the proportional band■ 1PB. Caution: doing this makes the system less stable.To reduce swings in steady-state temperature, increase the integral action time■ 1IT; system stability is thus increased, althoughits response speed is decreased.To increase the speed of response to the variations in temperature, increase the derivative action time■ 1DT. Caution: a highvalue makes the system sensitive to small variations and it may be a source of instability.RECALIBRATIONHave 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.With buttons■ and select 0AD or SAD: 0AD allows a calibration of 0, inserting a constant correction over the whole scaleof measurement. SAD allows a calibration of the top part of the measurement scale with a proportional correction between thecalibration point and 0.Press■ to display the value and then use + or to make the read value coincide with the value measured by thereference instrument.Exit from calibration by pressing button■ .OPERATIONThe L03B-- controller, size 71x98x61 mm (WxHxD), is to be secured to a DIN rail in such a position as to ensure that no liquid■infiltrates causing serious damage and compromising safety;Make sure that electrical connections comply with the paragraph “wiring diagrams”. To reduce the effects of electromagnetic■disturbance, keep the sensor and signal cables well separate from the power wires.Place the probe T1 inside the room in a point that truly represents the temperature of the stored product.■INSTALLATIONOUT1OUT2L1L2Channel 1 outputChannel 2 outputAlarmChannel 1 setpoint modificationChannel 2 setpoint modificationFig.1 - Front panelThank you for having chosen a Fantini Cosmi product.
