3.2 Behaviour after power-on
After supply voltage switch-on, the unit starts with the operating level.
The unit is in the condition which was active before power-off.
If the controller was in manual mode at supply voltage switch-off, the controller
will re-start with the last output value in manual mode at power-on.
3.3 Operating level
The content of the extended operating level is determined by means of BlueCon
trol (engineering tool). Parameters which are used frequently or the display of
which is important can be copied to the extended operating level.

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, where
by 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
BlueControl
®
.
Pb2 - Proportional band 2 (cooling) in engineering units [e.g. °C]
ti2 - Integral time 2 (cooling) in [s]r only, unless set to OFF
td2 - Derivative time 2 (cooling) in [s]r only, unless set to OFF
t2 - Minimum cycle time 2 (cooling) in [s] r only, unless Adt0
was set to “no self-tuning” during configuration by means of
BlueControl

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, vari
ous 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 ).
Optimization after start-up: (see page 4)
Optimization after start-up requires a certain separation between process value
and set-point. This separation enables the controller to determine the control pa
rameters 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 recom
mend a “Pulse attempt after start-up”.
Operation
-
-
-
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.

KS 90-1 / KS 92-1 17 Self-tuning
Operation
3.5.4 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 8).
Subsequently, a correcting variable step change to 100% is output.
The controller attempts to calculate the optimum control parameters from the pro
cess 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 parame
ters.
-
-
3.5.5 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 8)
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 parame
ters”, the optimized parameters are used for line-out to the set-point.

Operation
Optimization-at-the-set-point procedure:
The controller uses its instantaneous parameters for control to the set-point. In li
ned out condition, the controller makes a pulse attempt. This pulse reduces the
correcting variable by max. 20% 1, to generate a slight process value unders
hoot. The changing process is analyzed and the parameters thus calculated are re
corded in the controller. The optimized parameters are used for line-out to
theset-point.

increased by max. 20%.
KS 90-1 / KS 92-1 19 Self-tuning
Operation
3.5.7 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 mo
tor 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 volta
ge 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 actual position
-
-
Internal calculation
tt
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 self-tuning start, it will occur automatically by closing the actuator
once.
Unless the positioning limits were reached within 10 hours, a significant deviati
on between simulation and actual position may have occurred. In this case, the
controller would realize minor internal calculation, i.e. the actuator would be clo
sed by 20 %, and re-opened by 20 % subsequently. As a result, the controller
knows that there is a 20% reserve for the attempt.

3.5.8 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.

BlueControl - the engineering tool for the BluePortâcontroller series
3 engineering tools with different functionality facilitating the device configu
ration and parameter setting are available (see chapter 9: Accessory equipment
with ordering information).
In addition to configuration and parameter setting, blue control
â
is used for
data acquisition and offers long-term storage and print functions. Blue control
is connected to the device via the front-panel interface "BluePortâ" by means
of PC (Windows 95 / 98 / NT) and a PC adaptor.

Set-point gradient / ramp
To prevent setpoint step changes, a maximum rate of change is adjustable for
parameter r setpoint r r.SP. This gradient acts both in positive and negative
direction.
With parameter r.SP set to OFFas in the factory setting, the gradient is
switched off and setpoint changes are made directly.

4.4 Switching behaviuor

With these controllers, 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.
4.4.1 Standard ( CyCl= 0 )
Configuration level
The adjusted cycle times t1 and t2 are valid for 50% or -50% correcting varia
ble. 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 ¼
x t1 or¼x t2. The characteristic curve is also called “bath tub curve”

Parameters to be adjusted: t1 : min. cycle time 1 (heating) [s]

4.4.2 Switching attitude linear ( CyCl= 1 )
For heating (Y1), the standard method (see chapter 4.4.1) is used. For cooling
(Y2), a special algorithm for cooling with water is used. Generally, cooling is en
abled only at an adjustable process temperature (E.H2O), because low temperatu
-
-
res prevent evaporation with related cooling, whereby damage to the plant is
avoided. The cooling pulse length is adjustable using parameter t.on and is fi
-
xed for all output values.
The “off” time is varied dependent of output value. Parameter t.off is used for
determining the min “off” time. For output of a shorter off pulse, this pulse is
suppressed, i.e. the max. effective cooling output value is calculated according to
formula t.on /(t.on + t.off) w 100%.
Parameters to be adjusted: E.H2O: minimum temperature for water cooling
( PArA / Cntr) t.on: pulse duration water cooling
t.off: minimum pause water cooling

be used for changing the characteristic curve. The standard method (see section 4.4.1) is
also used for heating. Cooling is also enabled dependent of process temperature .

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 ).

7.1 DAC®– motor actuator monitoring
(Digital Actor Control DAC
®
)
With all controllers with position feedback Yp, the motor actuator can be monito
red for functional troubles. The DAC
®
function can be started by chosing the pa
-
rameter C.Fnc = 5 or 6 at the configuration level ( ConF):
ConF / Cntr / C.Fnc = 5 3-point-stepping controller with
w
position feedback Yp as potentiometer
ConF / Cntr / C.Fnc = 6 Continuous controller with integrated
w
positioner and position feedback Yp as
potentiometer
If an error occures, the controller switches to manual operation (ò - LED blinks)
and no impulses are given out any longer. If one of the relays shall switch when a
®
DAC
error occures, parameter dAC.A = 1 and inverse action O.Act = 1 must
be selected for the relevant output OUT.1 … OUT.4 in the ConF menu
( OUt.3 and 4 only possible if O.tYP = 0 [relay/logic]):
ConF / OUt.x/dAc.A = 1 Motor actuator monitoring (DAC) aktive
w
The system detects the following stepping controller errors:
-
defective motor
w
defective capacitor (wrong rotating direction)
w
wrong phase followers (wrong rotating direction)
w
defective force transmission at spindle or drive
w
excessive backlash due to wear
w
jamming of the control valve e.g. due to foreign body
w
In these cases the controller will change to manual operation and the outputs will
be switched off. Is the controller switched to automatic operation again or any
modification is done the controller activates the DAC function again and the out
puts will be setted.
Resetting of a DAC error:
After solving the technical problem the DAC errror can be acknowledged in the
error list. Thereafter the controller works again in normal operation mode.

Special functions
Functioning of the DAC function
No input filter should be defined for the Yp input ( PArA / InP.x/t.Fx=0).
Therewith no wrong detection of blocking or wrong method of operation can be
recognized.
The automatic calibration can be used with drives outfitted with spring assembly.
Execution of the calibration:
It is controlled if the mean alteration between two messurements is enough for
the DAC monitoring. The calibration will be stopped if the alteration between
two messurements is too small.
The position of 0% is searched. Therefor the drive will be closed until there is no
changing of the input signal for 0,5 sec.
Assuming that the drive is outfitted with spring assembly, the drive is opened for
2,8 sec. The drive should then still be within the spring assembly. This position is
allocated and stored as 0%.
With the same procedure the position for 100% is allocated and stored.
Simultaneously the motor running time is determined and saved as parameter tt.
Afterwards the controller sets the drive in the position before calibration.
Was the controller in automatic mode before calibration it will be set to automatic mode again otherwise it remains in manual mode.
g
g
g
The following errors can be occure during calibration:
the change of the Yp input is to small, no monitoring is possible
w
the motion is in wrong direction
w
the Yp input is broken
w
In these cases the automatic calibration will be stopped and the controller remains
in manual mode.
If the automatic calibration leads to no resonable results the calibration of the Yp
input can be done manual.
If the conroller reaches the positions of 0% or 100% the outputs will be switched
off. Also in manual mode it is not possible to exceed these limits.
Because no controller with continuouse output and Yp input is defined there
won't be the DAC function for this controlling type.

7.2 O2measurement
This function is available only on the instrument version with INP3.
As the O
-measurement result range can extend over many decades, automatic

display switch-over between“%”and“ppm“ was realized.
The instantaneous unit is displayed in
the lower line.
With set-point changing via keys I or
D, the unit of the set-point and of the
other parameters is displayed.
Lambda probes (l probes) are used as
sensors.
The electromotive force (in Volts) generated by l probes is dependent of instan
taneous oxygen content and temperature. Therefore, KS 9x-1 can only evaluate
exact measurement results, if it knows the sensor temperature.
Distinction of heated and non-heated lambda probes is made. Both can be evalua
ted by KS 9x-1.
Heated lambda probes
Controlled heating which ensures constant temperature is integrated in the heated
l probe. This temperature must be entered in KS 9x-1 parameter Probe temperature.
-
Parameter r Controller r Probe temperature r .....°C (/°F - dependent of confi-
guration)
Non-heated lambda probes
With the probe always operated at a fixed, known temperature, a procedure as
used for a heated probe can be used.
A non-heated l probe is used, unless the temperature is constant. In this case, the
probe temperature in addition to the probe mV value must be measured. For this
purpose, any temperature measurement with one of the analog inputs INP2 or
INP3 can be used. During function selection, the input must be set to X2 (second
process value).
7.2.1 Connection
Connect the input for the lambda probe to INP1.
Use terminals A15 and A17.
If necessary, temperature measurement must be connected to INP2 or INP3.

7.3 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.
In.1 < In.2 < ...< In.16 and Ou.1 < Ou.2 ...< Ou.16.

7.4 Loop alarm
The loop alarm monitors the control loop for interruption
(not with three-point stepping controller and not with signallers.)
With parameter LP.AL switched to 1(= loop alarm active), an interruption of
the control loop is detected, unless the process value reacts accordingly with
Y=100% after elapse of 2xTi.
The loop alarm shows that the control loop is interrupted. You should check hea
ting or cooling circuit, sensor, controller and motor actuator.
During self-tuning, the control loop is not monitored (loop alarm is not active).
7.5 Heating current input / heating current alarm
The heating current alarm monitors the heating current.
In addition to short circuit monitoring, checking either for overload (current >
heating current limit value) or for interruption (current < heating current limit va
lue) is done.
Each of the analog inputs can be used as measurement input.
If electrical heating is concerned, INP2 which is always provided can be configured for measuring range 0...50mA AC and connected directly using a heating current transformer.
