 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 :

appear in

is in operation mode and it is used to set the Start Pattern of PID program control (This parameter

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

execution of pattern No. 0. If set to

, it indicates the program will stop after executing the current pattern and the

to 2, it indicates that pattern No. 2 will execute next after 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

 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

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

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.
