2 - PROGRAMMAZIONE
2.1 - FAST PROGRAMMING OF SET POINTS
Press the key P then release it and the display will show “SP 1” alternating with the set value.
To change it, press the UP key to increase the value or the DOWN
key to decrease it.
These keys increase the value by one digit but if pressed down for
more than one second, the value increase or decreases rapidly
and after two seconds in the same condition, the speed increases
further to all the value desired to be set quickly.
The Set point “SP1" can be set at a value between the value set in
par. “SP1L” and the value set in par. “SP1H”.
If only Set Point 1 has been programmed, the unit will exit rapid
setting mode by pressing the key P once the desired value has been set.
If Set Point 2 can also be set by pressing and releasing key P
again, the display will show “SP 2” alternating with the set value.
To change it press the keys UP and DOWN.
The Set point "SP2" can be set with a value included between the
value set in par. “SP2L” and the value set in par. “SP2H”.
Once the desired value has been set, the unit will exit rapid setting
mode by pressing the key P.
Pressing the key P allows the user to exit rapid setting mode, after
visualising the last Set or automatically if no key is pressed for 15
seconds, after which time the display returns to the normal function
mode.
2.2 - PARAMETERS PROGRAMMING
To access the function parameters it is necessary to press key P
and keep it pressed for about 3 seconds, after which time the led
SET will light up, the display will show the code that identifies the
first parameter and using the UP and DOWN keys it will be possible to select the parameter that the user wishes to change.
Once the desired parameter has been selected by pressing the key
P, the display will show the parameter code and its setting, alternately. The setting can be changed by using the UP or DOWN keys.
Once the value has been set as desired, press key P again. The
new value will be memorized and the display will show the abbreviation of the parameter only once more.
By pressing the UP and DOWN keys, it is possible to select another parameter and to change it as described below.
By pressing the UP and DOWN keys, it is therefore possible to select another parameter and change it as described
To exit the programming mode, do not press any key for about 30
seconds, or keep the UP or DOWN key pressed until it exits the
programming mode.
If the user wishes to use this protection, he must set the password
number chosen in the parameter “PASS" and exit the parameterprogramming mode.
When the protection is active, in order to access the parameters
press the key P and keep it pressed for about 3 seconds, after
which the led SET will flash the display will show the parameter
“r.PAS” and pressing the key P again, the display will show “0" .
At this point, set the programmed password number using the keys
UP and DOWN and press key P.
If the password is correct, the display will show the code that identifies the first parameter and it will be possible to set the instrument's
parameters in the same way described in the previous paragraph.
The protection using passwords can be disabled by setting the par.
“PASS" = OFF.
The manufacturer's settings cause the password to protect all
parameters.
If the user desires after enabling the password using the “PASS", it
is possible to make some parameters programmable without the
password by using the following procedure.
Access programming using the password and select the parameter
you wish to make programmable without password.
Once the parameter has been selected, if the led SET is turned off,
it means that the parameter can be programmed using the password only (therefore it is protected) if instead it is lit up it means
that the parameter can be programmed without the password too
(not protected).
To change the parameter visibility, press the key U and keep it
pressed for about 1 sec. The led SET will change status showing
the new accessibility level of the parameter (turned on =not protected; turned off = protected by a password).
If the password is enabled and if some parameters have their protection removed, all the non-protected parameters will be shown
when programming is accessed and the par. “r.PAS” will be shown
which will allow the user to access the protected parameters.
NOTE: If the password is lost, remove the instrument's power supply, press key P and reinsert power, keeping the key pressed for
about 5 seconds.
All parameters will be accessed in this way and it will therefore be
possible to check and change the parameter “PASS".

4.2 - ON/OFF CONTROL
This regulation mode can be started by setting the parameter
"Cont" = On.FA. and acts on the outputs OUT1 and OUT2 depending on the measurement, of the set points “SP1” and “SP2”, of
the function mode “Fun1” and “Fun2”, and of the hystereses
“HSE1” and “HSE2” programmed.
The instrument starts up a ON/OFF regulation with asymmetric
hysteresis.
The regulators acts in the following way if they are inverted or if
heated (“Fun"=HEAt), they deactivate the output when the process
value reaches the value [SP]. To reactivate it when it goes below
the value [SP - HSE].
Vice versa, in the event of direct action or cooling ("Fun"=CooL),
they deactivate the output when the process value reaches the value [SP], to reactivate it when it rises above the value [SP + HSE].
The Set “SP2" can also be set as independent or dependent from
the set “SP1", through the parameter "SP2C".
If “SP2"is set as dependent (“SP2C" = di) the actual regulation setting of the output 2 will be [SP1+SP2].
The functioning of the outputs working in ON/OFF mode can be affected by delay functions that can be set on parameters “Ptd" and
“PtS" described below.

In order to obtain good stability of the process variable, in the event
of fast processes, the cycle time “tcr1” has to have a low value with
a very frequent intervention of the control output.
In this case use of a solid state relay (SSR) is recommended for
driving the actuator.
The Single Action PID control algorithm foresees the setting of the
following parameters :
"Pb" – Proportional Band
"tcr1" – Cycle time of the output
"Int" – Integral Time
"rS" – Manual Reset (if “Int =0 only)
"dEr" – Derivative Time
“FuOC” - Fuzzy Overshoot Control
This last parameter allows the variable overshoots at the start up of
the process or at the changing of the Set Point to be avoided.
Please remember that a low value on this parameter reduces the
overshoot while a high value increase it.

4.3 - NEUTRAL ZONE ON/OFF CONTROL
The neutral zone function is used to control systems that have an
element that causes positive increases (e.g. heating, humidifying
etc) and an element that causes a negative increase (e.g. cooling,
dehumidifying etc.).
This function can be activated when there are 2 outputs and it can
be obtained by programming the par. “Cont” = nr .
Using this programming, the instrument excludes the parameters
“SP2" , “Fun1" and “Fun2" from the function.
The regulation function acts on the outputs depending on the measurement, of the Set point “SP1”, and the hystereses “HSE1” and
“HSE2” that have been programmed.
The regulator acts in the following way: it turns off the outputs when
the process value reaches Set SP1 and activates the output OUT1
when the process value is less than [SP1-HSE1], or it turns on output OUT2 when the process value is greater than [SP1+HSE2].
Consequently the element that causes the positive increase is connected to output OUT1 while the negative increase element is connected to output OUT2.
The functioning of the outputs working in neutral zone mode can be
affected by delay functions that can be set on parameters “Ptd" and
“PtS" described below.

4.5 - AUTOTUNING FUNCTION
The AUTOTUNING function foresees the calculation of the PID
parameters through an OSCILLATING tuning cycle, which, when it
ends, the parameters are memorized by the instrument and remain
regular during regulation.
The function calculate the following parameters automatically:
“Pb” - Proportional ban
“tcr1” - output cycle time
“Int” - integral time
“dEr” - derivative time
“FuOC” - Fuzzy Overshoot Control
To activate the AUTOTUNING function, proceed as follows:
1) Set the Set point “SP1" desired.
2) Set the parameter "Cont" =Pid.
3) Set the parameter "Fun1" depending on the process to be
controlled by the output OUT1.
4) Set the parameter "Auto" as:
= 1 - if the autotuning is to be started automatically each time the
instrument is turned on.
= 2 - if the autotuning is to be started automatically when the
instrument is turned on the next time and, once tuning has been
completed, the parameter “Auto"=OFF is set automatically.
= 3 - if autotuning is started up manually, by the key U
= 4 - if autotuning is to be started automatically each time the
regulation set is changed.
5) Exit the parameter programming mode.
6) Connect the instrument to the controlled system.
TECNOLOGIC spa - TLK 96 S - OPERATING INSTRUCTIONS - Vr.01 - 09/05 - ISTR 06874 - PAG. 4
7) Start up autotuning turning off and on the machine if “Auto" = 1
or 2, pressing the key U (suitably programmed) if “Auto" = 3, or by
varying the Set value if “Auto" = 4.
At this point, the Autotuning function is started up and is marked by
the turning on of the led AT/CNT.
The regulator starts up a series of operations on the connected
system in order to calculate the most suitable PID regulation
parameters.
The autotuning cycle is limited to a maximum of 12 hours.
If the process has not ended in 12 hours the instrument will show
"noAt" .
Instead, if a probe error should occur, the instrument will interrupt
the cycle being carried out.
The values calculated by Autotuning will be memorized
automatically by the instrument at the end of the correct completion
of the autotuning cycle in the parameters related to PID regulation.
4.6 - REACHING OF “SP1” SET POINT AT CONTROLLED
SPEED (RAMP)
It is possible to reach the set point SP1 in a predetermined time (in
any case longer than the time the plant would naturally need). This
could be useful in those processes (heating or chemical
treatments, etc.) where the set point has to be reached gradually,
in a predetermined time.
The function is determined by the following parameter :

t im e [m in .]
Example with start from values lower than SP 1 and with
decreasing of SP 1.
Note : In case of PID control, if Auto-tuning is desired whilst the
ramp function is active, this will not be carried out until the tuning
cycle has been completed. It is therefore recommended that
Auto-tuning be started avoiding activating the ramp function and,
once the tuning is finished, deactivate Auto-tuning (“Auto” = OFF),
and program the desired ramp.
4.7 - DELAY IN OUTPUT ACTIVATION FUNCTION
In ON/OFF type regulation modes it is possible to start up two timed controls on the output activation.
The first control foresees a delay in the relative output activation
according to what is set on the parameters “Ptd1” and “Ptd2”.
The second control foresees an inhibition when the relative output
is started up if the time set on the parameters “PtS1” has “PtS2”
not been completed .
These functions can be useful for avoiding frequent interventions of
the outputs, especially when they control the compressors.
If the regulator request is missing during the delay phase, the planned output activation is cancelled.
The delay function are deactivated by programming the relative parameters = OFF.
During the output switch-on delay phases, the led for the relative
output involved flashes to shown the delay function is working.
