Basic System Structure
DTK 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, DTK will then control the temperature variation within a specific range.

Digital Filter and Linear Compensation Setting
To avoid interferences on input signal that would cause instable display value, two parameters are provided below for users to set up with.

In Regulation Mode, parameters

and

can be used to adjust filter status.

Filter Factors (setting range = 0~50; factory setting = 2). Linear Compensation Gain Calculation equation: PV = (Last

displayed PV * n + Measured 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 Measured Value lies within the range of “Last displayed PV + / – 1.00”. Therefore, it is recommended to set a larger value

when noise interference is serious enough to cause large temperature oscillations.

When PV display value is different from user’s expectation, Linear Compensation can be adjusted via parameters

and

in Regulation Mode.

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

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 = Measured

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

For example: Measured 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, setting linear compensation value solves the deviation issue. If temperature deviation varies upon different temperatures, calculate the linear deviation error and adjust the temperature by setting Gain and Compensation value.

Analog Output Compensation

When the output mode is set to analog current output (4~20 mA), user’s desired output value can be obtained by using compensation

function. For example, the analog output 1 can be adjusted for compensation in parameters

and

in Regulation Mode.

The output value can be positive or negative (+/-) and can be changed by pressing the Up/Down key on the temperature controller. The

scale of each pressing is an increase or decrease of 1 uA. Ex: To change the current output range from 4~20 mA to 3.9~20.5 mA, set

parameter

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

Set parameter

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

To control the output manually: Set parameter

in Initial Setting Mode.

To set output to 0%: Set parameter

(output 1) or

(output 2) to

in Operation Mode.

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

value (for example: 4~20 mA, adjusting analog value will be 4 mA). Set parameter Mode.

to your desired value in Regulation

To set output to 100%: Set parameter

(Output 1) or

in Operation Mode.

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

value (for example: 4~20 mA, adjusting analog value will be 20 mA). Set parameter Mode.

to your desired value in Regulation

Check Firmware Version and Output Type
When the temperature controller is ON, the PV and SV display will show firmware version, output type, and input type during the first 3 seconds. PV indicates the firmware version. Ex: V110 indicates firmware version V1.10. SV (first digit) indicates the output type of OUT1.
N: No function, V: Voltage pulse output, R: Relay output, C: Current output SV (second digit) indicates the output type of OUT2. No display: No OUT2 (default), R: Relay output The 3rd and 4th SV digit are input types.
K, J, T, E, N, R, S, B, L, U, TX (TXK), JP (JPT100), PT (Pt100), CU (CU50), NI (NI120)

Selection for Heating/Cooling/Alarm/Dual-Loop Output Control
DTK series features 1 set of Output Control (OUT1) and 1 set of Alarm Output (ALARM1), both of which are built-in. Users can also purchase a 2nd set of Alarm Output (ALARM2). Using 1 set of Output Control:

In Initial Setting Mode, set parameter Using 2nd set of Output Control:

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

When the 1st set of alarm and the 2nd set of output control are used for dual output control, set parameter

in Initial

Setting Mode to controls such as heating (H1H2), cooling (C1C2), heating/cooling (H1C2), or cooling/heating (C1H2).

The Dead Band parameter

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

diagram below, the purpose for setting the Dead Band function is to reduce waste of energy from frequent acts of heating/cooling. Ex: For

example, if SV = 100 degree and

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

When the controller is in PID control and dual loop output mode, parameter

sets the P value of the 2nd set of PID. The

1st set of PID is generated when TUNE = AT, but user can also manually set the PID value. The P value of the 2nd set of PID = the

P value of 1st set of PID x

. The I and D value of the 2nd set of PID remains the same as the 1st set of PID.

Control Mode Setting
There are 3 control modes, which are ON-OFF, PID, 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 shown in the diagram below.

Setting of Dead Band for both outputs: Set Dead Band via parameter

in Regulation Mode.

PID Mode: When setting for heating or cooling, the program performs PID operation via input temperature and setting temperature, with the operation result output for control of the temperature. A PID parameter and control period must be set for this function; these parameters can also be generated automatically via auto-tuning (AT).

a. Set PID parameters and the control period: PID parameters can be adjusted manually according to system characteristics or created automatically by AT. Proportional error compensation is used when I parameter is set to 0 for adjusting reduced deviation from time to reach the temperature.The Control Period is the period of PID operation, if the control period is 10 seconds, it means a PID operation is carried out every 10 seconds. 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, lifespan of the relay shall be considered. A short control period will shorten the lifespan of relay.
b. 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 for the first and second group.

Set parameter

in Initial Setting Mode.

To set for heating or cooling control: Select desired output control via parameter

in Initial Setting Mode. If only

single output control is performed, items to be selected are H1 and C1 (H for heating, C for cooling, and 1 for output 1). If

dual output control is performed, the items to be selected are as follows: H1H2, C1H2,… C1C2 (H for heating, C for cooling,

1 for output 1, and 2 for output 2).

Set control period: In Regulation Mode parameter, PV is displayed as “o’x’ – ‘y'”. ‘x’ is 1 (output 1) or 2 (output 2). ‘y’ is H

(heating) or C (cooling).

Set double output Coef: Set Coef value via parameter

in Regulation Mode.

Setting of Dead Band for both outputs: Set Dead Band via parameter

in Regulation Mode.

Set control to running mode: Set parameter

in Operation Mode.

Set AT: Set parameter

in Regulation Mode. The selected number of PID sets will be adjusted

automatically. After that, a PID value will be created automatically and the display will automatically alter into

Note: When performing AT, set up for the entire system must be completed, 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. However, it is normally operated in combination with switchover of PID control.
a. Switch from PID control to manual control: Control output will retain the original control output before switching over to manual control. E.g., if the control output calculated by PID is 20% before the switch, then the control output is 20% after

switching to manual control. You may force a fixed output value after the switch, for example, controlling the output to be 40%. b. Switch from manual control to PID control: If manual control is 40% before switching over to PID control, the program will take this 40% after the switch-over as the initial value for calculating the PID value and then output the new control. Note: If power of the controller is switched off under manual control mode, the original output % will be retained when the power is switched on again.

Set parameter

in Initial Setting Mode.

Set control period: In Regulation Mode parameter, PV is displayed as “o’x’ – ‘y'”. ‘x’ is 1 (output 1) or 2 (output 2). ‘y’ is H

(heating) or C (cooling).

Set output %: In Operation Mode parameter, PV is displayed as “oUt’x'”. ‘x’ is 1 (output 1) or 2 (output 2).

Tune Function

This control features Auto_Tuning for automatic generation of PID parameters (only applicable when control mode is set to PID control). Auto_Tuning: Through output of full heating or cooling, temperature is allowed for upward and downward oscillation. Obtain
parameters for the magnitude and period to calculate PID parameters. In addition, save the temperature setting value obtained from performing AT, so that it could be used with PID control. After Auto_Tuning, PID control will be carried out automatically.

AT setting: Set parameter

in Regulation Mode.

Limits on control of output range

Maximum and minimum output can be limited. If the original maximum control output is 100% and the minimum control output is 0%, you may set the maximum control output to 80% and the minimum control output to 20%.

Setting the upper limit of control output: Set values for parameters

(output 1),

(output 2) in Operation Mode.

Setting the lower limit of control output: Set values for parameters

(upper limit) /

(lower limit) in Initial Setting Mode.

If lower limit is altered to 0 and upper limit is altered to 200, the limit function will be enabled in the following conditions:

When setting the SV value, range for the setting will be limited to 0 ~ 200.

Under ON-OFF and PID control conditions, the control output will be forced to shut off if the PV value exceeds the upper/lower limit.

(Alarm output is still normal)

CRC check code: CRC (Cyclical Redundancy Check) is obtained via the following steps. 1. Load in a 16-bit register FFFFH as the CRC register. 2. Perform an exclusive OR operation for the first byte of the data and low byte of CRC register. Place the operation result back to the CRC register. 3. Right-shift the bits in the CRC register and fill the high bits with “0”. Check the lowest bit removed. 4. If the removed lowest bit is “0”, repeat step 3. Otherwise, perform an exclusive OR operation for the CRC register and the value of A001H. Place the operation result back to the CRC register. 5. Repeat step 3 and 4 until the 8 bits (1 byte) are all right-shifted. 6. Repeat step 2 and 5 and calculate all the bits in the data to obtain CRC check code.
Please be aware of order of transmission for the high/low bytes in the CRC register.

Error code
When error occurs, you can read 1000H registers via communication. Please refer RS485 section for displaying the different error reason with hexadecimal H8001~H8007 codes.
Panel shows error code :
: Sensor is not connected.
: Sensor type is error, the measured temperature has exceeded the usable range of the sensor.

When installing the temperature controller, a certain surrounding space should be maintained (as shown below) to ensure proper

cooling and easy removal of mounting accessories.

At least 60 mm space for upper and lower sides and 40 mm space for left and right sides.

Mounting and Bracket Installation
4848 series: Step 1: Insert the controller through the panel cutout. Step 2: Slide M3*0.5 nut into the opening in the top of the mounting bracket and insert the M3*0.5*30mm mounting screw in the mounting
bracket. Insert the mounting bracket into the mounting groove at the right and left of the controller and push the mounting bracket forward until the bracket stops at panel wall. Step 3: Tighten screws on bracket to secure the controller in place. (The screw torque should be 0.4 to 0.5N.m )

Step 3: Tighten screws on bracket to secure the controller in place. (The screw torque should be 0.4 to 0.5N.m )

Wiring Diagrams and Precautions

Tighten the screw to the torque between 0.4 and 0.5N.m. To avoid signal interference, it is suggested that the power cable and the signal cable to be set separately. Please use solid wires between 14AWG/2C and 22AWG/2C. Maximum 300V and rated temperature to 105°C for input power pins.

The warning symbol

on the case indicated the ports for power input pins 1 and 2. If the power supply is connected to other

ports, the controller will be burned, and personnel injury or fire may occur.

Please use relay output models within the rated load. Otherwise, the cable and crimp terminal may build up heat due to overload.

When the temperature exceeds 50°C, contact burning may occasionally occur.

Please use the crimp terminal of maximum 5.8 mm.
