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. 

 

 

EVENT Inputs Function

 

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. 

 

 

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

 

 

again, then the program will follow the step before hold and start to execute through 

the rest of the time. 

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 

  key, and then the temperature set point of the current execution step will display on SV 

display. 
After select 

, press

 

  key, and then the residual time of the current 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 

set to ” 1”, it means signal feedback function is activated and will come up selections as follows: 

a. 

: 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 

to be ”1” for auto setting or ”0” for manual setting. 

c.

 

: D/A value when value fully closes. Set 

to be ”1” for auto setting or “0” for manual setting. 

Note: If feedback function setting is with problem, program will see the setting as feedback disabled.
