2.1 - FAST PROGRAMMING OF SET POINTS

Push key “P”, then release it and the display will visualise “SP 1” alternatively to the programmed value.

To modify the value, press “UP” key to increase it or the “DOWN” key to decrease it.

These keys change the value one digit at a time but if they are pressed for more than one second, the value increases or decreases rapidly and, after two seconds in the same condition, the changing speed increases in order to allow the desired value to be reached rapidly.

Set Point “SP1” can be programmed with a value that is between the value programmed on par. “SPL1” and the one programmed on par. “SPH1”.

Once the desired value has been reached, by pushing key P it is possible to exit by the fast programming mode, or (if the instrument have 2 outpus) it is possible to visualise and modify the Set point

Set Point “SP2” can be programmed with a value that is between

and the one programmed

To exit the fast Set programming it is necessary to push key P, after the visualisation of the last Set Point, or alternatively, if no key is pressed for approx. 15 seconds, the display will return to normal

2.2 - PARAMETERS PROGRAMMING

To access the instrument’s function parameters, press the key P and keep it pressed for about 5 seconds, after which the display will visualised the code that identifies the first parameter.

Using the UP and DOWN keys, the desired parameter can be selected and pressing the P key, the display will alternately show the parameter code and its setting that can be changed with the UP and DOWN keys.

Once the desired value has been set, press the key P again: the new value will be memorised and the display will show only the code of the selected parameter.

Pressing the UP and DOWN keys, it is possible to select another parameter and change it as described.

To exit the programming mode, do not press any key for about 20 seconds, or keep the UP or DOWN key pressed until it exits the programming mode.

2.3 - PARAMETER PROTECTION USING THE PASSWORD AND

PARAMETER PROGRAMMING LEVELS

The instrument has a parameter protection function using a password that can be personalised, through the “PASS” parameter.

If one wishes to have this protection, set the password number desired in the parameter “PASS”.

When the protection is working, press the P key to access the parameters and keep it press for about 5 seconds, after which the display will show the par. “r.PAS” .

At this point, press P and the display will show “0” .

Using the UP and DOWN keys, set the password number programmed and press the key "P".

If the password is correct, the display will visualise the code that identifies the first parameter and it will be possible to programme the instrument in the same ways described in the previous section.

Protection using a password can be disabled by setting the parameter “PASS” = OFF.

The password protection hides all the configuration parameters behind a factory set password to avoid unwanted changes being made to the programming of the controller. To make a parameter accessible without having to enter a password follows this procedure.

Enter the programming using the Password and select the parameter which is desired to be accessible with no password protection. Once the parameter has been selected, if the SET led is off, this means that the parameter is programmable by entering the password (it’s then “protected”) if it’s instead on, this means the parameter is programmable without password (not protected).

If you want to change the accessibility of the parameter push U key and keep it pressed for approx.1 sec : SET led will change its state indicating the new access level of the parameter (on= not protected; off=protected).

In case some parameters are no longer protected, when one tries to have access at the programming, the display will show all the parameters not protected and the par. “r.PAS” (through which will be possible to have access to the “protected” parameters.)

Note: If the Password gets lost, just cut off the supply, push P key and keeping it pressed for 5 seconds whilst switching on the supply to the instrument.

In this way it’s possible to have access to all the parameters, verify and modify the par. “PASS”.

3 - INFORMATION ON INSTALLATION AND USE

3.1 - PERMITTED USE

The instrument has been projected and manufactured as a measuring and control device to be used according to EN61010-1 for the altitudes operation until 2000 ms.

The use of the instrument for applications not expressly permitted by the above mentioned rule must adopt all the necessary protective measures.

The instrument CANNOT be used in dangerous environments

(flammable or explosive) without adequate protection.

The installer must ensure that EMC rules are respected, also after the instrument installation, if necessary using proper filters.

Whenever a failure or a malfunction of the device may cause dangerous situations for persons, thing or animals, please remember that the plant has to be equipped with additional devices which will guarantee safety.

3.2 - MECHANICAL MOUNTING

The instrument, in case 33 x 75 mm, is designed for flush-in panel mounting. Make a hole 29 x 71 mm and insert the instrument, fixing it with the provided special bracket. We recommend that the gasket is mounted in order to obtain the front protection degree as declared. Avoid placing the instrument in environments with very high humidity levels or dirt that may create condensation or introduction of conductive substances into the instrument. Ensure adequate ventilation to the instrument and avoid installation in containers that house devices which may overheat or which may cause the instrument to function at a higher temperature than the one permitted and declared. Connect the instrument as far away as possible from sources of electromagnetic disturbances such as motors, power relays, relays, solenoid valves, etc.

3.3 - ELECTRICAL CONNECTION

Carry out the electrical wiring by connecting only one wire to each terminal, according to the following diagram, checking that the power supply is the same as that indicated on the instrument and

ASCON TECNOLOGIC S.r.l. - TLK 38 S - OPERATING INSTRUCTIONS - Vr.03 - ISTR-MTLK38SENG02 - PAG. 2

ADVANCED THERMOELECTRIC Toll-free: 1-866-665-5434 (603) 888-2467 [email protected]

that the load current absorption is no higher than the maximum electricity current permitted.

As the instrument is built-in equipment with permanent connection inside housing, it is not equipped with either switches or internal devices to protect against overload of current: the installation will include an overload protection and a two-phase circuit-breaker, placed as near as possible to the instrument, and located in a position that can easily be reached by the user and marked as instrument disconnecting device which interrupts the power supply to the equipment. It is also recommended that the supply of all the electrical circuits connected to the instrument must be protect properly, using devices (ex. fuses) proportionate to the circulating currents. It is strongly recommended that cables with proper insulation, according to the working voltages and temperatures, be used. Furthermore, the input cable of the probe has to be kept separate from line voltage wiring. If the input cable of the probe is screened, it has to be connected to the ground with only one side.

Whether the instrument is 12 V version it’s recommended to use an external transformer TCTR, or with equivalent features, and to use only one transformer for each instrument because there is no insulation between supply and input. We recommend that a check should be made that the parameters are those desired and that the application functions correctly before connecting the outputs to the actuators so as to avoid malfunctioning that may cause irregularities in the plant that could cause damage to people, things or animals.

4.1 - MEASURING AND VISUALIZATION

Depending on the model required the input accept:

C : Thermocouples temperature probes (J,K,S and ZIS Infrared sensors), mV signals (0..50/60 mV, 12..60 mV), Thermoresistances

PT100.

E : Thermocouples temperature probes (J,K,S and ZIS Infrared sensors), mV signals (0..50/60 mV, 12..60 mV), Thermistors PTC and NTC.

I : normalized analogue signals 0/4..20 mA

V : normalized analogue signals 0..1 V, 0/1..5 V, 0/2..10 V

Depending on the model, using par. “SEnS”, it’s possible to select the type of input probe, which can be :

- for thermocouples J (J), K (CrAL), S (S) or for infrared sensors serie ZIS with linearization J (Ir.J) or K (Ir.CA)

- for thermoresistances Pt100 IEC (Pt1) or thermistors PTC KTY81-

121 (Ptc) or NTC 103AT-2 (ntc)

- for normalised signals in current 0..20 mA (0.20) or 4..20 mA

(4.20)

- for normalised signals in tension 0..1 V (0.1), 0..5 V (0.5), 1..5 V

(1.5), 0..10 V (0.10) or 2..10 V (2.10).

- for normalised signals in tension 0..50 mV (0.50), 0..60 mV (0.60),

12..60 mV (12.60).

We recommend to switch on and off the instrument when these parameters are modified, in order to obtain a correct measuring.

For the instruments with input for temperature probes (tc, rtd) it’s possible to select, through par. “Unit”, the unit of measurement

(°C, °F) and, through par. “dP” (Pt100, PTC and NTC only) the desired resolution (0=1°; 1=0,1°).

Instead, with regards to the instruments with normalised analogue input signals, it is first necessary to program the desired resolution on par. “dP” (0=1; 1=0,1; 2=0,01; 3=0,001) and then, on par.

"SSC" , the value that the instrument must visualise at the beginning of the scale (0/4 mA, 0/12 mV, 0/1 V o 0/2 V) and, on par. "FSC", the value that the instrument must visualise at the end of the scale (20 mA, 50 mV, 60 mV, 5 V or 10 V).

The instrument allows for measuring calibration, which may be used to recalibrate the instrument according to application needs, by using par. “OFSt” and “rot”.

Programming par. “rot”=1,000, in par. “OFSt” it is possible to set a positive or negative offset that is simply added to the value read by the probe before visualisation, which remains constant for all the measurements.

If instead, it is desired that the offset set should not be constant for all the measurements, it is possible to operate the calibration on any two points.

In this case, in order to decide which values to program on par.

“OFSt” and “rot”, the following formulae must be applied :

“rot” = (D2-D1) / (M2-M1) “OFSt” = D2 - (“rot” x M2) where:

M1 =measured value 1

D1 = visualisation value when the instrument measures M1

M2 =measured value 2

D2 = visualisation value when the instrument measures M2

It then follows that the instrument will visualise :

DV = MV x “rot” + “OFSt” where: DV = visualised value MV= measured value

Example 1: It is desired that the instrument visualises the value effectively measured at 20° but that, at 200°, it visualises a value lower than 10° (190°).

Therefore : M1=20 ; D1=20 ; M2=200 ; D2=190

“rot” = (190 - 20) / (200 - 20) = 0,944

“OFSt” = 190 - (0,944 x 200) = 1,2

Example 2: It is desired that the instrument visualises 10° whilst the value actually measured is 0°, but, at 500° it visualises a 50° higher value (550°).

Therefore : M1=0 ; D1=10 ; M2=500 ; D2=550

“rot” = (550 - 10) / (500 - 0) = 1,08

“OFSt” = 550 - (1,08 x 500) = 10

By using par.

“FiL” it is possible to program time constant of the software filter for the input value measured, in order to reduce noise sensitivity (increasing the time of reading).

In the event of probe error, it is possible to set the instrument so that the outputs OUT1 and OUT2 continues to work in cycles according to the times programmed in the parameter “ton1” -

“ton2” (activation times) and “toF1” - “toF2” (deactivation times).

If an error occurs on the probe the instrument activates the relative output for the time “ton”, then deactivates it for the time “toF” and so on whilst the error remains.

Programming “ton” = OFF the output in probe error condition will remain switched off.

Programming instead “ton” to any value and “toF” = OFF the output in probe error condition will remain switched on.

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].

ASCON TECNOLOGIC S.r.l. - TLK 38 S - OPERATING INSTRUCTIONS - Vr.03 - ISTR-MTLK38SENG02 - PAG. 3

ADVANCED THERMOELECTRIC Toll-free: 1-866-665-5434 (603) 888-2467 [email protected]

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.

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.

4.4 - PID CONTROL active Set Point

The Single Action PID control can be obtained by programming par.

"Cont" = Pid and works on the output OUT1 depending on the

“SP1” , on the functioning mode "Fun1” the instrument’s PID algorithm with two degree of freedom.

In this mode, the output OUT2 works in ON/OFF mode. and on

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. o ff

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.

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.

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.

ASCON TECNOLOGIC S.r.l. - TLK 38 S - OPERATING INSTRUCTIONS - Vr.03 - ISTR-MTLK38SENG02 - PAG. 4

ADVANCED THERMOELECTRIC Toll-free: 1-866-665-5434 (603) 888-2467 [email protected]

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.

Example “PtS” with “Fun” = CooL

In addition to these delays, it is possible to prevent the activation of all the outputs after turning on the instrument for the time set in parameter “od” .The function is deactivated for “od" = OFF.

During the switch on delay phase the display shows the indication or alternates with the normal planned display screen.

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 :

"SLor" - Gradient of ramp expressed in unit/minute

S V

[ U n it ]

4.8 - PARAMETERS CONFIGURATION BY “A01”

The instrument is equipped with a connector that allows the transfer from and toward the instrument of the functioning parameters through the device A01 with 5 poles connector.

This device it’s mainly useable for the serial programming of the instruments which need to have the same parameters configuration or to keep a copy of the programming of an instrument and allow its rapid retransmission.

To use the device A01 it’s necessary that the device or instrument are being supplied.

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 Autotuning be started avoiding activating the ramp function and, once the tuning is finished, deactivate Auto-tuning (“Auto” = OFF), and program the desired ramp.

Instrument supplied from the device

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.
