3.7 Self-tuning

(automatic adaption of control parameters) For determination of optimum process parameters, self-tuning is possible. After starting by the operator, the controller makes an adaptation attempt, whereby the process characteristics are used to calculate the parameters for fast line-out to the set-point without overshoot.

 The following parameters are optimized when self-tuning:

Parameter set 1:

Pb1

ti1

td1

Pb2

ti2

td2

Operation

Proportional band 1 (heating) in engineering units [e.g. °C] Integral time 1 (heating) in [s] r only, unless set to OFF Derivative time 1 (heating) in [s] r only, unless set to OFF Minimum cycle time 1 (heating) in [s]. This parameter is optimized only, unless

parameter Cntr/Adt0 was configured for “no self-tuning” using BlueControl

Proportional band 2 (cooling) in engineering units [e.g. °C] Integral time 2 (cooling) in [s] r only, unless set to OFF Derivative time 2 (cooling) in [s] r only, unless set to OFF Minimum cycle time 2 (cooling) in [s]. This parameter is optimized only, unless

parameter Cntr/Adt0 was configured for “no self-tuning”using BlueControl

9499-040-93811 / 59537-1 Page 15 of 88 Pro-16

Operation

3.7.2 Optimization after start-up or at the set-point

There are two methods of optimization; either after start-up or at the set-point. As control parameters are always optimal only for a limited process range, various methods can be selected dependent of requirements. If the process behavior is very different after start-up and directly at the set-point, parameter sets 1 and 2 can be optimized using different methods. page 23).

Switch-over between parameter sets dependent of process status is possible (see

 Optimization after start-up: (see page 17)

Optimization after start-up requires a certain separation between process value and setpoint. This separation enables the controller to determine the control parameters by evaluation of the process whilst progressing to the set-point. This method optimizes the control loop from the start conditions to the set-point, whereby a wide control range is covered. We recommend selecting optimization method “Step attempt after start-up” with tunE = 0 first. Unless this attempt is completed successfully, we then recommend a

“Pulse attempt after start-up”.

 Optimization at the set-point: (see page 17)

For optimizing at the set-point, the controller outputs a disturbance variable to the process. This is done by briefly changing the output variable. The process value changed by this pulse is evaluated. The detected process parameters are converted into control parameters and saved in the controller. This procedure optimizes the control loop directly at the setpoint. The advantage is in the small control deviation during optimization.

3.7.3 Selecting the method ( ConF/ Cntr/ tunE)

Selection criteria for the optimization method:

tunE Step attempt

after start-up

= 0 sufficient set-point

reserve is provided

= 1 sufficient set-point

= 2 Only step attempt after

Pulse attempt after start-up

Sufficient set-point reserve: inverse controller: process value is (10% of rnGH - rnGL) below the set-point direct controller: process value is (10% of rnGH - rnGL) above the set-point

9499-040-93811 / 59537-1 Page 16 of 88 Pro-16

3.7.4 Step attempt after start-up

Condition: - tunE = 0 and sufficient set-point reserve provided or - tunE = 2

The controller outputs 0% correcting variable or Y.Lo and waits, until the process is at rest (see start-conditions on page 15). Subsequently, a correcting variable step change to 100% or Y.Hi is output.

The controller attempts to calculate the optimum control parameters from the process response. If this is done successfully, the optimized parameters are taken over and used for line-out to the set-point.

With a 3-point controller, this is followed by “cooling”. After completing the 1st step as described, a correcting variable of -100% or Y.Lo (100% cooling energy) is output from the set-point. After successful determination of the

“cooling parameters”, the controller will proceed to the setpoint using the optimized parameters.

3.7.5 Pulse attempt after start-up

Condition: - tunE = 1 and sufficient set-point reserve provided. The controller outputs 0% correcting variable or Y.Lo and waits, until the process is at

rest (see start conditions page 15) Subsequently, a short pulse of 100% or Y.Hi is output (Y=100%) and reset. The controller attempts to determine the optimum control parameters from the process

response. If this is completed successfully, these optimized parameters are taken over and used for stabilized to the set-point.

With a 3-point controller, this is followed by “cooling”. After completing the 1st step as described and stabilized to the set-point, correcting

variable "heating" remains unchanged and a cooling pulse (100% cooling energy) is output additionally. After successful determination of the “cooling parameters”, the optimized parameters are used for stabilized to the set-point.

Operation

3.7.6 Optimization at the set-point

Conditions:

 A sufficient set-point reserve is not provided at self-tuning start (see page 16).  tunE is 0 or 1  With Strt = 1 configured and detection of a process value oscillation by more

than ± 0,5% of (rnG.H - rnG.L) by the controller, the control parameters are preset for process stabilization and the controller realizes an optimization at the

set-point (see figure “Optimization at the set-point”).

 when the step attempt after power-on has failed

9499-040-93811 / 59537-1 Page 17 of 88 Pro-16

Operation

 with active gradient function ( PArA/ SETP/ r.SP OFF), the set-point

gradient is started from the process value and there isn't a sufficient set-point reserve.

 Optimization-at-the-set-point procedure:

The controller uses its instantaneous parameters for control to the set-point. In stable condition, the controller makes a pulse attempt. This pulse reduces the correcting variable by max. 20% 1, to generate a slight process value undershoot. The changing process is analyzed and the parameters thus calculated are recorded in the controller. The optimized parameters are used for stabilized to the set-point.

Optimization at the set-point

With a 3-point controller, optimization for the “heating“ or “cooling” parameters occurs dependent of the instantaneous condition.

While the controller is in the "heating-phase" the heating-parameters are determined. If the controller is in the "cooling-phase" the cooling-parameters are determined.

1 If the correcting variable is too low for reduction in stable condition it is increased by max. 20%.

9499-040-93811 / 59537-1 Page 18 of 88 Pro-16

Operation

 Optimization at the set-point for 3-point stepping controller

As position feedback is not provided, the controller calculates the actuator position internally by adjusting an integrator with the adjusted actuator travel time.

For this reason, precise entry of the actuator travel time (tt), as time between stops is highly important. Due to position simulation, the controller knows whether an increased or reduced pulse must be output. After supply voltage switch-on, position simulation is at 50%. When the motor actuator was varied by the adjusted travel time in one go, internal calculation occurs, i.e. the position corresponds to the simulation:

Simulation real position

Internal calculation

Internal calculation always occurs, when the actuator was varied by travel time tt in one go , independent of manual or automatic mode. When interrupting the variation,

internal calculation is cancelled. Unless internal calculation occurred already after selftuning start, it will occur automatically by closing the actuator once.

Unless the positioning limits were reached within 10 hours, a significant deviation between simulation and actual position may have occurred. In this case, the controller would realize minor internal calculation, i.e. the actuator would be closed by 20 %, and re-opened by 20 % subsequently. As a result, the controller knows that there is a 20% reserve for the attempt.

9499-040-93811 / 59537-1 Page 19 of 88 Pro-16

3.7.7 Self-tuning start

The operator can start self-tuning at any time. For this, keys simultaneously. With blinking in the second row the active adaptation is displayed Ad:PIR. The controller outputs 0%, waits until the process is at rest and starts selftuning: Ad:Stp

The self-tuning attempt is started when the following prerequisite is met:

 The difference between process value i set-point must be  10% of the set-point

range ( SP.Hi - SP.LO) (with inverse action: process value smaller than setpoint, with direct action: process value higher than set-point).

After successful self-tuning, the AdA-LED is off and the controller continues operating with the new control parameters.

 Self-tuning cancellation by the operator:

Self-tuning can always be cancelled by the operator. For this, press simultaneously. The controller continues operating with the old parameters in automatic mode in the first case and in manual mode in the second case.

 Self-tuning cancellation by the controller:

An error detected during self-tuning means that the technical conditions prevent successful self-tuning.

In this case, self-tuning was cancelled by the controller. The controller switches off its outputs (controller output 0%), to avoid exceeding the setpoint.

The user has two possibilities to acknowledge a failed adaptation:

1. Press keys The controller continues controlling using the old parameters in automatic mode. The self-tuning error must be acknowledged in the error list.

2. Press key Display of error list at extended operating level. After acknowledgement of the error message, the controller continues control in automatic mode using the old parameters.

Cancellation causes: r page 13: "Error status"

Ù and È key

 Acknowledgement of failed self-tuning

When pressing the

Ù key, the controller switches over to correcting variable display

(Y ....). After pressing the key again, the controller goes to the error list of the extended

operating level. The error message can be acknowledged by switching the message to 0 using the Ì - or the È key. After acknowledging the error message, the controller continues operating in the automatic mode, using the parameters valid prior to self-tuning start.

3.7.8 Examples for self-tuning attempts

(controller inverse, heating or heating/cooling)

9499-040-93811 / 59537-1 Page 20 of 88 Pro-16

Start: heating power switched on Heating power Y is switched off (1). When the

change of process value X was constant during one minute (2), the power is switched on (3).

At the reversal point, the self-tuning attempt is finished and the new parameter are used for controlling to set-point W.

Start: heating power switched off The controller waits 1,5 minutes (1). Heating

power Y is switched on (2). At the reversal point, the self-tuning attempt is finished and control to the set-point is using the new parameters.

Self-tuning at the set-point a The process is controlled to the set-point. With the

control deviation constant during a defined time (1), the controller outputs a reduced correcting variable pulse (max. 20%) (2). After determination of the control parameters using the process characteristic (3), control is started using the new parameters (4).

Three-point controller a The parameter for heating and cooling are

determined in two attempts. The heating power is switched on (1). Heating parameters Pb1, ti1, td1 and t1 are determined at the reversal point. The process is controlled to the setpoint (2). With constant control deviation, the controller provides a cooling correcting variable pulse (3). After determining its cooling parameters Pb2, ti2, td2 and t2 (4) from the process characteristics , control operation is started using the new parameters (5).

Operation

9499-040-93811 / 59537-1 Page 21 of 88 Pro-16

During phase 3, heating and cooling are done simultaneously!

3-point-stepping controller After the start (1) the controller closes the

actuator (2 Out.2). When the difference between process value and set-point is big enough (3), the changing of the process value is monitored for 1 min. (4). Afterwards the actuator is opened (5 Out.1). If the reversal point is reached (6) or there are made enough measurements, the parameters are detected and are adopted.

3.8 Help for manual tuning

The optimization aid should be used with units on which the control parameters shall be set without self-tuning.

For this, the response of process variable x after a step change of correcting variable y can be used. Frequently, plotting the complete response curve (0 to 100%) is not possible, because the process must be kept within defined limits.

The process characteristic is frequently affected by various factors such as process value, correcting variable and material differences.

To comply with these requirements, the controller can be switched over between two parameter sets. Parameter sets PArA and PAr.2 are provided for heating and cooling.

Dependent of configuration, switch-over to the second parameter set (ConF/LOG/Pid.2) is via key

or interface (OPTION).

Self-tuning is always done using the active parameter set, i.e. the second

parameter set must be active for optimizing.

Max. three alarms can be configured and assigned to the individual outputs. Generally, outputs OuT.1... OuT.6 can be used each for alarm signalling. If more than one

signal is linked to one output the signals are OR linked. Each of the 3 limit values Lim.1 … Lim.3 has 2 trigger points H.x (Max) and L.x (Min), which can be switched off individually (parameter = “OFF”). Switching difference HYS.x of each limit value is adjustable.

H.1 = OFF

Normally open: See examples (ConF / Out.x / O.Act = 0) Normally closed: The output relay action is inverted (ConF/ Out.x / O.Act = 1)

The alarm LED always shows the threshold violation on (out of limits, switching point). If several alarms are used can be checked at the operating level, which alarm is active (

Ù …r Lim.1 Ù … Lim.3)

The variable to be monitored can be selected separately per configuration for each

alarm.

Operation

Relative set-point Weff is used. E.g with a ramp, this is the changing set-point rather than the target set-point.

The alarm output is suppressed after switch-on or after a set-point change, until the process value is within the limits for the first time. At the latest after elapse of time 10 x ti1 the alarm is activated (ti1 = integral time 1; parameter r Cntr). If ti1 is switched off (ti1 = OFF), this is considered as Î , i.e. the alarm is not activated before the process value was within the limits once.

The effective set-point Weff for control. Absolute

Process value - internal set-point. The internal setpoint is used. E.g. with a ramp, this is the target set-point instead of the varying effective set-point Weff.

After switch-on or after a set-point change, the alarm output is suppressed , until the process value is within the limits for the first time.

generated.The alarm is reset automatically, when the process value is "within the limits" (including hysteresis) again.

exceeding the limit value, an alarm is output. A latched alarm persists, until it is reset manually.
