Note 1 : An external 250Ω precision resistor should be connected when the current input is selected as the input temperature sensor type..
Note 2 :
(Operation mode) must be set if user wish to specify decimal point position. Except for the thermocouple B, S, R type, the decimal
point positions of all the other thermocouple type input sensors can be set.
The default range of analog input is -999 ~ 9999. For example, when a 0~20mA analog input is selected as the input temperature sensor type, -999
indicates 0mA and 9999 indicates 20mA. If change the input range to 0 ~ 2000, then 0 indicates 0mA and 2000 indicates 20mA. One display scale is
equal to 0.01mA.

Operation
There are three modes of operation: operation, regulation and initial setting. When power is applied, controller gets into the operation mode.
Press the
key to switch to regulation mode. If the
key is pressed for more than 3 seconds, controller will switch to the initial setting
mode. Pressing the
key while in the regulation mode or initial setting mode, forces the controller to return to the operation mode.

Dual Loop Output Control (Heating / Cooling Control)
Dead band
Temperature control can be achieved either by heating or cooling. In DTB series, heating and
cooling can be operated simultaneously (Dual Loop output control) to perform temperature
control. When Dual Loop output control are used, two control outputs must be connected to the
heating and cooling devices. Please refer to the following for the operation:

Alarm Outputs
There are up to three groups of alarm outputs and each group allows thirteen alarm types in the initial setting mode. The alarm output is
activated whenever the process temperature value (PV) is getting higher or lower than the set point of alarm limit.

Current Transformer (CT) Function
The Current Transformer (CT) function is used with the alarm output. When using a current transformer (CT) with the controller, change the
corresponding alarm output mode to mode 13 (alarm output set value is 13), then turn to operation mode and set the current lower-limit and
current upper-limit. You can set current alarm range between 0.5A ~ 30A, display resolution is 0.1A and measure accuracy is +/- 0.5A.
10
EVENT Inputs Function
5
There are two optional event inputs (contact inputs) supported (EVENT1and EVENT2) in DTB series.
EVENT1: RUN/STOP operation can be executed by RUN/STOP parameters (Operation Mode) or via the communication. User also can
control RUN/STOP operation by EVENT 1 in DTB series. The control output is ON if the circuit of EVENT 1 is open when the
controller is operating. Otherwise, the controller will stop output if the circuit of EVENT 1 is short or when the system parameter of
the controller is set to STOP mode.
EVENT2: DTB series allows user can switch two temperature setting value by changing the status (open/short) of EVENT 2. Each
temperature setting value has independent control parameters.
11
PID Program Control (Ramp/Soak Program Control)
Description of Function and Parameters Setting:
PID program control by 8 patterns (Pattern No. 0~7) is supported in DTB series. Each pattern contains 8 steps (step No. 0 ~ 7), one Link
Pattern parameter, one Cycle parameter and one Actual Step parameter.
Start Pattern:
is in operation mode and it is used to set the Start Pattern of PID program control (This parameter appear in
mode only).
Steps : Include set point X and execution time T, these two parameters setting. The set point (SV) should reach temperature X after the period
of execution time T. If the set point is the same as the result of the previous setting, then it is called Soak program control. If not, then it
is called Ramp program control. Therefore, PID program control is also called Ramp/Soak program control. The default of step No. 0
in this controller is Soak program control. The controller will control the temperature (PV) to reach the set point X and then keep the
temperature at set point X. The period of execution time is time T which provided by step No. 0.
Link Pattern Parameter : For example, when set
to 2, it indicates that pattern No. 2 will execute next after the execution of pattern No.
0. If set to
, it indicates the program will stop after executing the current pattern and the temperature will keep at the set point of
the last step.
Cycle Parameter : Additional execution cycle number. For example, when set
to 2, it indicates that pattern No. 4 should execute twice
in addition. Include origin one time execution, total execute three times.
Actual Step Parameter : Execution step number per pattern (can set to 0 ~ 7). For example, when set
to 2, it indicates that pattern No
7 will not execute other steps than step 0 to step2.
Execution : When
is set to
, the program will start to execute in order from the step 0 of start pattern. When
is set to
, the program will stop and the control output is disabled. When
is set to
, the program will stop and the temperature
at that time will be controlled at the set point before program stop. Select
again, then the program will restart and execute from
step 0 of start pattern. When
is set to
, the program will hold and the temperature at that time will be controlled at the set
point before program hold. Select
of the time.
again, then the program will follow the step before hold and start to execute through the rest
Display : During PID program control, the SV default display is P-XX, P indicates the current execution pattern and XX indicates the current
execution step. Press
to change the display item. After select
, press
, press
key, and then the temperature set point of the
key, and then the residual time of the current
current execution step will display on SV display. After select
execution step will display on SV display.

PID Control
One group can be selected from any one of 4 groups PID parameters (P, I, D, IOF) for PID control. After AT, PID value and temperature setting
will be stored in the selected one group. : PIDn, n=0~4 from which 0~3 correspond to each PID parameter. : n=4, auto PID
parameter. Program will automatically select a most useful PID parameter based on current temperature setting. Displayed SV values
correspond to
: Temperature setting corresponded to the selected PID parameter via user-defined or AT.

Valve Control:
When use valve control as output control, there are 2 Relay outputs for motor forward/reverse control, one (output 1) for valve open the other
(output 2) for valve close. The output volume is controlled by valve open/close and it can be set with feedback function enabled or disabled.
When feedback is disabled, output 1 will keep output while valve fully opens and output 2 will keep output while valve fully closes. But if
feedback is enabled, please follow the parameter setting for valve control as follows:
: Time for valve from full close to full open.
: Dead Band setting of valve. The value of current valve output minus previous one must be greater than Dead Band value; otherwise,
valve will remain OFF.
: Signal feedback setting, ON for enabling feedback and OFF for disabling feedback.
When
a.
set to ” 1”, it means signal feedback function is activated and will come up selections as follows:
: Upper/Lower limit of valve feedback by auto-tuning. must set to for showing up this selection.
b.
: D/A value when value fully opens. Set
: D/A value when value fully closes. Set
to be ”1” for auto setting or ”0” for manual setting.
to be ”1” for auto setting or “0” for manual setting.
c.
Note: If feedback function setting is with problem, program will see the setting as feedback disabled.
