3.5 Self-tuning
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- Proportional band 1 (heating) in engineering units [e.g. °C]
ti1- Integral time 1 (heating) in [s]
r only, unless set to OFF
td1- Derivative time 1 (heating) in [s]
r only, unless set to OFF
t1- Minimum cycle time 1 (heating) in [s]
r only, unless Adt0 was set to “no self-tuning” during
configuration by means of 8800/8840 Configurator.
Pb2- Proportional band 2 (cooling) in engineering units [e.g. °C]

3.5.2 Optimization after start-up or at the set-point
The two methods are optimization after start-up and 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
behaviour is very different after start-up and directly at the set-point, parameter
sets 1 and 2 can be optimized using different methods. Switch-over between
parameter sets dependent of process status is possible (see page 25).
Optimization after start-up: (see page 17)
Optimization after start-up requires a certain separation between process value
and set-point. This separation enables the controller to determine the control
parameters by evaluation of the process when lining out 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
recommend a “Pulse attempt after start-up”.
Self-tuning168840 profiler
Optimization at the set-point: (see page 18)
For optimizing at the set-point, the controller outputs a disturbance variable to the
process. This is done by changing the output variable shortly. 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 set-point. The advantage
is in the small control deviation during optimization.
3.5.3 Selecting the method ( ConF/ Cntr/ tunE)

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% 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% (100%
cooling energy) is output from the set-point. After successfull determination of
the “cooling parameters”, line-out to the set-point is using the optimized
parameters.
8840 profiler17Self-tuning
Operation
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% 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 line-out to the set-point.
With a 3-point controller, this is followed by “cooling”.
After completing the 1st step as described and line-out 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 line-out to the set-point.

Self-tuning188840 profiler
Operation
Optimization-at-the-set-point procedure:
The controller uses its instantaneous parameters for control to the set-point. In
lined out 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 line-out to
the set-point.

With a 3-point controller, optimization for the “heating“ or “cooling” parameters
occurs dependent of the instantaneous condition.
These two optimizations must be started separately.
1 If the correcting variable is too low for reduction in lined out condition it is
increased by max. 20%.
8840 profiler19Self-tuning
Operation
Optimization at the set-point for 3-point stepping controller
With 3-point stepping controllers, the pulse attempt can be made with or without
position feedback. Unless feedback is provided, the controller calculates the
motor actuator position internally by varying 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:
Simulationactual position
Internal calculation
tt
Internal calculation always occurs, when the actuator was varied by travel time
tt in one go
variation, internal calculation is cancelled. Unless internal calculation occurred
already after self-tuning 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.

3.5.4 Self-tuning start
Start condition:
For process evaluation, a stable condition is required. Therefore, the
w
controller waits until the process has reached a stable condition after
self-tuning start.
The rest condition is considered being reached, when the process value
oscillation is smaller than ± 0,5% of (rnG.H - rnG.L).
For self-tuning start after start-up, a 10% difference from (SP.LO ... SP.Hi)
w
is required.

3.5.5 Self-tuning cancellation
By the operator:
Self-tuning can always be cancelled by the operator. For this, press Ù and È
key simultaneously.With controller switch-over to manual mode after self-tuning
start, self-tuning is cancelled. When self-tuning is cancelled, the controller will
continue operating using the old parameter values.
By the controller:
If the Err LED starts blinking whilst self-tuning is running, successful self-tuning
is prevented due to the control conditions. In this case, self-tuning was cancelled
by the controller. The controller continues operating with the old parameters in
automatic mode. In manual mode it continues with the old controller output
value.
3.5.6 Acknowledgement procedures in case of unsuccessful self-tuning
1.Press keys Ù and È simultaneously:
The controller continues controlling using the old parameters in automatic
mode. The Err LED continues blinking, until the self-tuning error was
acknowledged in the error list.
2.Press key Ò (if configured):
The controller goes to manual mode. The Err LED continues blinking,
until the self-tuning error was acknowleged in the error list.
3.Press key Ù :
Display of error list at extended operating level. After acknowledgement
of the error message, the controller continues control in automatic mode using

3.6 Manual self-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.
Values T

3.7 Second PID parameter set
The process characteristic is frequently affected by various factors such as
process value, correcting variable and material differences.
To comply with these requirements, the 8840 profiler can be switched over
between two parameter sets.
Parameter sets PArA and PAr.2 are provided for heating and cooling.
Dependent of configuration ( ConF/LOG/Pid.2), switch-over to the second
parameter set( ConF/LOG/Pid.2) is via one of digital inputs di1, di2, di3,
key è or interface (OPTION).
g
Self-tuning is always done using the active parameter set, i.e. the second
parameter set must be active for optimizing.
8840 profiler25Second PID parameter set
Operation
3.8 Alarm handling
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 and delay dEl.x of each limit value is adjustable.
The variable to be monitored can be selected seperately for each alarm via
configuration
The following variables can be monitored:
process value
w
control deviation xw (process value - set-point)
w
control deviation xw + suppression after start-up or set-point change
w
After switching on or set-point changing, the alarm output is suppressed,
until the process value is within the limits for the first time. At the latest after
expiration of time 10 ti1, the alarm is activated. (ti1 = integral time 1;
parameter r Cntr)
If ti1 is switched off (ti1 = OFF), this is interpreted as Î, i.e. the alarm
is not activated, before the process value was within the limits once.

If measured value monitoring + alarm status storage is chosen ( ConF / Lim /
Fnc.x=2/4), the alarm relay remains switched on until the alarm is resetted in
the error list ( Lim 1..3 = 1).

Resetting the controller configuration to factory setting (Default)
r chapter 12.1 (page 85)
8800/8840 Configurator - the engineering tool for the West controller series
3 engineering tools with different functionality facilitating 8840 profiler
configuration and parameter setting are available (see chapter 10: Accessoryequipment with ordering information).
In addition to configuration and parameter setting, the engineering tools are
used for data acquisition and offer long-term storage and print functions. The
engineering tools are connected to the 8840 profiler via the front-panel
interface by means of PC (Windows 95 / 98 / NT) and a PC adaptor.
Description 8800/8840 Configurator:
see chapter 9: 8800/8840 Configurator (page 77).

- at power on
Set-point gradient / ramp
To prevent set-point step changes, parameter
r set-point r r.SP can be adjusted
to a maximum rate of change. This gradient is effective in positive and negative
direction..
With parameter r.SPset to OFF (default), the gradient is switched off and
set-point changes are realized directly.

4.5 8840 profiler cooling functions
With the 8840 profiler , configuration parameter CYCL (ConF/ Cntr/ CYCL)
can be used for matching the cycle time of 2-point and 3-point controllers. This
can be done using the following 4 methods.
4.5.1 Standard ( CyCl= 0 )
The adjusted cycle times t1 and t2 are valid for 50% or -50% correcting
variable. With very small or very high values, the effective cycle time is extended
to prevent unreasonably short on and off pulses. The shortest pulses result from
¼x t1 or¼x t2. The characteristic curve is also called “bath tub curve”

4.5.2 Heating and cooling with constant period ( CyCl= 3 )
t1 and t2 are met in the overall
t
output range . To prevent
unreasonably short pulses, parameter
t1 t2/
tp is used for adjusting the shortest
pulse duration. With small correcting
50%
30%
values which require a pulse shorter
than the value adjusted intp, this
tp
pulse is suppressed. However, the
controller stores the pulse and
t1 t2/
totalizes further pulses, until a pulse
of duration tp can be output.

For direct action of the continuous controller, the controller action must be
changed ( ConF / Cntr / C.Act = 1 ).
To prevent control outputs Out.1 and Out.2 of the continuous controller from
switching simultaneously, the control function of outputs Out.1 and Out.2 must
be switched off ( ConF / Out.1 and Out.2 / Y.1 and Y.2 = 0 ).

5.3 Input scaling
When using current, voltage or resistance signals as input variables for InP.1,
InP.2 or/and InP.3 scaling of input and display values at parameter setting level

With a ramp segment (time), the set-point runs linearly from

p
With a ramp segment (gradient), the set-point runs linearly
from the start value (end value of previous segment) towards
the target value (Sp) of the relevant segment. The gradient is
determined by parameter Pt.
With a hold segment, the end set-point of the previous segment
is output constantly during a defined time which is determined
by parameter Pt.
With a step segment, the program set-point goes directly to the
value specified in parameter Sp. With configured control
deviation alarms, the alarm is suppressed within band
monitoring.
The last segment in a program is the end segment. When
reaching the end segment, output of the setpoint output last is
continued.
Waiting and operator call
a
All segment types except end segment can be combined with ”Wait at the end
and operator call”.
If a segment with combination ”wait” was configured, the programmer goes to
stop mode at the segment end (run LED is off). Now, the programmer can be
restarted by pressing the start/stop key (>3s), via interface or digital input.

7.3.6 Bandwidth monitoring
Bandwidth monitoring is valid for all
program segments. An individual
bandwidth can be determined for each
program.
When leaving the bandwidth (b.Lo =
low limit; b.Hi = high limit), the
programmer is stopped (run LED
flashes). The program continues running
when the process value is within the
predefined bandwidth again.
g
With segment type Step and bandwidth monitoring activated, the control
deviation alarm is suppressed, until the process value is in the band again.
g
If band alarm signalling as a relay output is required, a control deviation alarm
with the same limits as the band limits must be configured.

7.3.8 Behaviour after mains recovery or sensor error
Mains recovery
After power recovery, the last program set-points and the time elapsed so far are
not available any more. Therefore, the programmer is reset in this case. The
controller uses the internal set-points and waits for further control commands (the
run LED blinks).
Sensor error
With a sensor error, the programmer goes to stop condition (the run LED blinks).
After removal of the sensor error, the programmer continues running.

This function is only selectable with 8800/8840 Configurator (engineering tool)!
The 8840 profiler can be used as Modbus master ( ConF / othr / MASt =1).
The Modbus master sends its data to all slaves (Broadcast message, controller
adress 0). It transmits its data (modbus adress AdrU) cyclic with the cycle time
Cycl to the bus. The slave controller receives the data transmitted by the masters
and allocates it to the modbus target adress AdrO. If more than one data should
be transmitted by the master controller ( Numb > 1) , the modbus adress AdrU
indicates the start adress of the data that should be transmitted and AdrO
indicates the first target adress where the received data should be stored. The
following data will be stored at the logically following modbus target adresses.
With this it is possible e.g. to specify the process value of the master controller as
set-point for the slave controllers.

8.2 Linearization
Linearization for inputs INP1 or INP3
Access to table “ Lin” is always with selection of sensor type S.TYP = 18:
special thermocouple in INP1 or INP3, or with selection of linearization S.Lin
1: special linearization.
Dependent of input type, the input signals are specified in µV or in Ohm
dependent of input type.
With up to 16 segment points, non-linear signals can be simulated or linearized.
Every segment point comprises an input (In.1 … In.16) and an output (Ou.1
… Ou.16). These segment points are interconnected automatically by means of
straight lines. The straight line between the first two segments is extended
downwards and the straight line between the two largest segments is extended
upwards. I.e. a defined output value is also provided for each input value.
When switching an In.x value to OFF, all other ones are switched off.
Condition for these configuration parameters is an ascending order.
