Basic System Structure
DT3 obtains the temperature of the controlled environment from the sensor and sending the measured data to the electronic processor. After computing and under a fixed control cycle, it proportionally sends the heating signal via different output interfaces such as relays, voltage pulse or DC currents. By providing power to the heater and raise temperature, DT3 will then control the temperature variation within a specific range.

Digital Filter and Linear Compensation Setting

In “Regulation Mode”,

and

parameters can be used to ajust the filter status and to avoid interferences on input signal.

: Filter Factors (setting range=0~50; factory setting=8). Digital Filter Calculation equation: PV=(Last displayed PV * n +

Measure Value)/ (n+1). When the parameter value is small, the PV display is close to the Measured Value. When the parameter

value is large, the PV response is slow.

: Filter Range (setting range=0.10~10.00/). If factory setting = 1, it means the controller will begin Digital Filter

Calcaulation when the Measure Value lies within the range of “Last displayed PV + / – 1.00/”. Therefore, it is recommended to

set a larger value when noise interferences is serious.

When PV display value is different than user’s expectation, Linear Compensation function can be set by

and

parameters in”Regulation Mode”.

: Linear Compensation Value (setting range= -99.9 ~ +99.9). Linear Compensation Calculation equation: PV = Measure

Value + Compensation Value.

For example: Measure Value=25.0; Compensation = 1.2. After applying to the Compensation equation PV=26.2.

Linear Compensation Gain (setting range = -0.999~0.999). Linear Compensation Gain Calculation equation: PV =

Measure Value* (1 + Gain/1.000) + Compensation.

For example: Measure Value=25.0; Gain= 0.100. After applying to the Gain calculation equation PV= 25.0 * (1 + 0.100 / 1.000) = 27.5

If temperature deviation is the same in every temperature, settting linear compensation value can solve deviation problem. If temperature

deviation varies upon different temperatures, calculate the linear deviation error and adjusts the temperature by setting Gain and

Compensation value.

Applications of Analog Voltage & Current Input
The input range of analog voltage and current are used as the uppler/lower limit of the controller’s voltage and current setting. When setting up the desire voltage or current, it must lies within the range of upper/lower limit. For example: If the range of analog input voltage is 0~5V, the upper limit setting will be 5000 and lower limit setting will be 0. If the decimal setting is set to 3 decimal place, a input voltage of 2.5V will displays as 2.500. The equation of Display Value = (Upper limit setting of controller Lower limit setting of controller)*(Input voltage- Analog lower limit)/(Analog upper limit analog lower limit) + Lower limit setting of controller.

Disable the Cold Junction Function

The cold conjunction function of a thermocouple is set to ENABLE, but in some cases, we can set it to DISABLE.

In Initial Setting Mode,

is used to set the first digit (Y) of Yxxx, (when Y=0, Enable; when Y=1, Disable).

Analog Output Compensation

When the output mode is set to analog current output (4~20mA) or linear voltage output (0~10V), user’s desire output value can be

attained by using compensation function. For example, the analog output 1 can be adjusted in

and

parameters in

“Regulation Mode”. The output value can be positive or negative (+/-) and it can be changed by pressing the Up/Down key on the

temperature controller. The scale of each pressing is an increase or decrease of 1uA and 1mV.

For example: To change the current output range from 4~20mA to 3.9~20.5mA, set

to 500 (20.5-20=0.5mA; 0.5mA/1uA= 500).

and set

to -100 (3.9-4=-0.1mA; -0.1mA/1uA=-100).

To control the output manually: Set parameter

to

inInitial Setting Mode.

To set output to 0%: Set parameter

to

or

to

inOperation Mode.

To adjust the lower limit of analog output: Input a desire value and check the meter to adjust the analog input value to desire value

(For example: 4~20 m A, adjusting analog value will be 20 m A). Set parameter desire value in Regulation Mode.

(Output 1) or

(Output 2) to your

To set output to 100%: Set parameter

Retransmission and Compensation Adjusting
When the input value changes, the retransmission output will also be changed correspondingly. For example: If retransmission = 4~20mA ; uppler/lower limit = 100.0 ~ 0. Wen the controller reads 0, it outputs 4mA; when the controller reads 100, it outputs 20mA. The value can also be a negative number to generate a negative slope. For negative slope, sets upper/lower limit = 0~100.0. In this case, when the controller reads 0, it outputs 20mA; when the controller reads 100, it outputs 4mA. Refer to the slope diagram below.

Output = Negative Slope

Output = Positive Slope

(Figure 1: Propotional Output Diagram)

To set Retransmission to positive/negative slopes (a Retransmission board must be installed first): In Initial Setting Mode set

the

parameter, the last digit (Y) of xxxY indicates when Y=0 positive slope; when Y=1 negative slope.

To adjust the lower limit of Retransmission:

a Make sure the slope of Retransmission is positive.

b Set lower limit value larger than the display value: InInitial Setting Modeset the value in

larger than the display value

(PV). c Input the analog value to meter, check the meter and adjust the analog input value: In Regulation Mode, enter the new value

into

. For example, if the range is 4~20mA, the new value will be 4mA.

To adjust the upper limit Retransmission:

a Make sure the slope of Retransmission is positive.

b Set upper limit value smaller than the display value: InInitial Setting Modeset the value in

smaller than the display

value (PV). d Input the analog value to meter,check the meter and adjust the analog input value: In Regulation Mode, enter the new value

into

. For example, if the range is 4~20mA, the new value will be 4mA.

Check the Firmware Version and Output Type
When the temperature controller is ON, the PV and SV display will shows firmware version, output type and accessory functions in first 3 seconds. PV (first 3 digits) indicates the firmware version. Ex: 110 indicates firmware version V1.10. PV (4th digit) indicates the function of accessory 1.

Selection for Heating/Cooling/Alarm/Dual Loop Output Control

DT3 series offers 1 set of Output Control (OUT1) that is built-in internally and 2 sets of Alarm Output(ALARM1 ALARM2). User can also

purchase a 2nd set of Output Control (OUT2) or a 3rd set of Alarm Output (ALARM3). Using 1 set of Output Control :

InInitial Setting Mode, sets

to Heating (H1) or Cooling(C1) mode.

Using 2nd set of Output Control:

When the 2nd set of output control (OUT2) is used as a 3rd set of arlarm (ALARM3), set Cooling + Alarm 3(C1A2) in Initial Setting Mode.

to Heating + Alarm 3(H1A2) or

OUT2 output types in relay, voltage pulse, analog current, linear voltage and SSR output can all be used for ALARM ON-OFF. For

9

example, OUT2 is set to analog current output. It outputs 4mA when alarm is OFF and outputs 20mA when alarm is ON.

When the 2nd set of output control (OUT2) is used as dual output control, set

to heating (H1H2); cooling (C1C2);

Heating/Cooling(H1C2) or Cooling/Heating (C1H2) control mode inInitial Setting Mode.

The Dead Band parameter

is automatically enabled when the temperature controller is in dual output control. As shown

in the diagram follow. The purpose of Dead Band function is to reduce the energy wastage of frequent heating/cooling actions. For

example, if SV = 100 degree and

= 2.0, there will be no output when the temperature is between 99~101°C..

SV Control Mode Setting

There are 4 methods for setting SV of the temperature setting; they are Fixed, Slope, Program and Remote.

Fixed SV Mode: controls the temperature to directly rise to a fixed setting value

Set parameter

to

in Initial Setting Mode

Set the target temperature: set SV value by a parameter in Operation Mode

Slope SV Mode: Control temperature rises at a slope (unit: /min.) to a fixed value.

E.G., if parameter

set to 1, set a slope of 0.5 and set SV to 200.0; this means the temperature rises 0.5 every minute

from room temperature up to 200.0.

If parameter

set to 0, set a slope of 5 and set SV to 200; this means the temperature rises 5 every minute from room

temperature up to 200.

Set parameter

to

in Initial Setting Mode

Set rising slope (unit: /min. or /s): set rising slope by parameter

in Regulation Mode

Set target temperature: set SV value by a parameter in Operation Mode

Set unit for rising slope (unit: /min. or /s): for parameter

in Initial Setting Mode, set the corresponding Y

position value to xxYx (Y can be 0 or 1; Y= 0: /min.; Y=1: /s).

Program SV mode: This means the temperature setting value is not a fixed value but a setting curve defined by the user according to his-her requirements. By way of PID control, the temperature input rises along with the defined temperature curve. As to how to input the temperature setting curve, the machine provides 16 patterns with 16 steps each, together with a linking parameter, a loop parameter, and a number of executions. Each step has 2 parameters (temperature setting value and time). If the initial step has a time parameter set to 0, temperature will rise from room temperature at the initial slope up to the target temperature. After setting these parameters, each temperature controller will have its own set of initial pattern and initial step for

10

creating its own temperature setting curve. Some of the terms are explained as follows: a Initial pattern: set the program to start running at a sequential number of patterns b Initial Step: set the program to start running at a sequential number of steps c Initial Slope: If the time setting of the initial step of the initial pattern is set to 0, an initial slope shall be set to allow the temperature to rise from room temperature to the setting value. d Step: includes 2 parameter settings: a setting point X and an executing time T, representing the setting value (SV) to rise to X after time T. If the setting point X is identical to the previous setting, this process is called a Soak, otherwise a Ramp, therefore this control procedure is also called a Ramp Soak control. The first running procedure is preset as a Soak control, to set the temperature control to setting point X in advance and maintain the temperature at X, at a duration of T. e Link Parameter: the number of the subsequent pattern to be linked after executing this pattern. If set to END, the program mode will end but maintain the last setting value; if set to STOP, all the program controls will end with the output switched off. f Number of loops: Number of extra loops to be carried out for the pattern. If set to 1, the pattern will be carried out 2 times. g Executing step: Number of steps executed for each pattern. h Wait time, wait temperature: After reaching the program temperature value, a wait time and wait temperature can be set; if the current temperature is not within the range of (temperature setting value ± wait temperature), the set wait time will start to count down until the currently measured temperature reaches the range of (temperature setting value ± wait temperature) of each step before proceeding to the subsequent step. An alarm will be issued if the range of (temperature setting value ± wait temperature) is not reached when the count down reaches 0. i Execution: If the setting control is in running mode, the program will start running from the initial pattern and initial step, and carry out commands one by one. When the setting control is in end mode, the program will stop running and give out an output disable. When setting control is in stop control and temperature is controlled at the setting value before the stop, by re-selecting the start status, the program will start running from the initial pattern and initial step. When setting control is in pause control and temperature is controlled at the setting value before the stop, by re-selecting the start status, the program will start running from the step where the program was paused and carry out the remaining part.

Remote Mode: Input of setting value can be dynamic, an analog value (voltage or current) can be converted into a dynamic input

value. Two methods can be used for the conversion: positive slope or negative slope, they are depicted as follows: a Positive slope Remote setting: Display of Remote analog input is in positive proportion with setting input, e.g.: Remote input

type is selected as 1~5 V analog voltage, Remote higher limit of input is set as 5000, Remote lower limit of input is 1000,

decimal display is set as 0; when Remote input is 5V, the screen shows 5000; when Remote input is 2V, the screen show

2000; this is the dynamic setting of the screen display. (Dynamic setting value =(Remote higher limit of input Remote lower

limit of input)*(Remote input value – lower limit of Remote input)/( higher limit of Remote input – lower limit of Remote input)+

Remote lower limit of input) b Negative Slope Remote setting: Display of Remote analog input is in negative proportion with setting input, e.g.: Remote

input type is selected as 1~5 V analog voltage, Remote higher limit of input is set as 5000, Remote lower limit of input is 1000, decimal display is set as 0; when Remote input is 5V, the screen shows 1000; when Remote input is 2V, the screen show 4000; this is the dynamic setting of the screen display.

Control Mode Setting
There are 4 control modes; ON-OFF, PID, FUZZY and MANUAL. ON-OFF Mode: For heating output, the output is off when input is greater than the setting value; output is on when input is smaller
than (setting value adjustment sensitivity setting value). For cooling output, the output is on when the input is greater than (setting value + adjustment sensitivity setting value); output is off when input is smaller than the setting value. If one of 2 outputs is set for heating and the other for cooling, a non-action zone can be set as follows.

PID Mode: When set for heating or cooling, the program performs PID operation via input temperature and setting temperature, with the operation result output for the temperature control. A PID parameter and control period must be set for this function; these parameters can also be generated automatically via auto-tuning (AT). a A total of six sets of PID parameters are available, one of which can be selected for carrying out PID, and the program may automatically select a set of PID that is most close to the input value. In order to achieve this, each set of PID parameters has a reference input setting value which allows the user to set for manual setting or for auto- tuning (AT). E.G., for the six sets of PID parameters as shown below, SV is reference input setting. Let us select the 4th set as the PID running parameter: i.e., P=40, I=220, D=55, IOF=30%. If we select AT to find the set closest to the setting value with a setting input of 230, the program will automatically find the second set as the running parameter for PID operation.

Set PID parameters and the control period: in which PID parameters can be adjusted manually according to system characteristics or created automatically by AT, the pre-set integral value is set as I parameter 0, allowing for promptly

achieving the setting value; unit is % output; proportional error compensation is: when I parameter is set to =0, for the

adjustment of reduced time to reach the temperature. The Control Period is the period of PID operation, if the control period is

10s, it means a PID operation is carried out every 10s. The result is then output to control the temperature. If the system

heats up quickly, the control period shall not be set too long. For relay output, the lifespan of the relay shall be considered; a

short period will shorten the lifespan of relay. c Coef and DeadBand are added in the PID parameter for double output (one for heating and one for cooling). Coef refers to

the ratio between the first and second portions of output (P parameter of second group =Coef*P, Coef= 0.01~99.99);

DeadBand is the overlapping temperature of the P output of the first group and the second group.

Note: When performing AT, the entire system must complete setting; i.e. the input Sensor must be wired and correctly set, and the

output must be connected to a heater or cooler pipe.

MANUAL Mode: Manual control function, may force output of a fixed value; normally operated by combining switchover of PID

control. a Switch from PID control to manual control: Control output will maintain the original control output before switching over to

manual control. E.g., if the control output before the PID calculation is 20%, then the control output after switching to manual

control is 20%. You may force a fixed output value after a switchover, for example: controlling the output to be 40%. b Switch from manual control to PID control: if manual control before switching-over to PID control is 40%, the program will

take 40% as the initial value for calculating the PID value and output the new control.

Note: If power of machine is switched off in manual control mood, the output % will be maintained when the power is switched on again.

FUZZY Mode: This comprises 2 parts: PID parameters and Fuzzy exclusive parameters. Since Fuzzy control is calculated based

on P.I.D values of PID control, the user must first set P.I.D parameters or perform auto tuning (AT) to produce these parameters. In

addition, Fuzzy control includes the following 2 exclusive parameters. a Fuzzy Gain Setting: altering this value will directly affect the calculation of Fuzzy gain. Increasing this value will directly

enhance the Fuzzy control; decreasing this value will weaken the Fuzzy control. It is recommended that this value shall be

decreased for systems with slow reaction to heating/cooling. This value may be increased for systems with quick reaction to

heating/ cooling. b Set Fuzzy DeadBand: The effective bandwidth of Fuzzy control, when PV value enters into the range of SV-FZDB

<PV<SV+FZDB, Fuzzy control will stop calculation. I.e., when the PV is within this temperature range, its Fuzzy control is fixed.

Setting of multiple PID sets

When PID control is selected, the system provides 6 sets (PID 0~5) PID parameter sets (P, I, D and IOF parameter) to be selected by the user. In general conditions, one set of PID (P0) is adequate. For different setting values (SV), when the same PID value is not adequate to control the precision, the user may set up multiple sets of PID parameters for the system to automatically switch-over to an applicable PID set. Set only one PID set:

Set parameter

to 0 (PID 0, the first set) inRegulation Mode, set parameter

to ON; at this time, the System starts to

Auto Fine-tune the PID value. During the calculation, AT LED lights up in the display panel. When the PV value generates 2 curves of temperature oscillation based on the SV value, the AT process is completed and the AT LED in the panel goes out. The calculated PID

parameters are displayed in

If more SV groups are required, PID2~PID5 can be set up with the same sequence as described above.

Tune Function

This machine provides 2 tuning methods (Auto_Tuning and Self_Tuning) for automatic generation of PID parameters (only applicable

when control mode is set to PID control).

Auto_Tuning: by full output of heating or cooling, temperature is allowed to oscillate up and down. Attain parameters of the

magnitude and period, calculate P, I, D, IOF parameters; in addition, save the temperature setting value for performing AT, for the

use of PID control. After Auto_Tuning, PID control will be carried out automatically.
