and the setting value SV-(AL-L).
Absolute value upper- and lower-limit:
5
This alarm output operates when PV value is higher than the setting value AL-H or lower
than the setting value AL-L.
Absolute value upper-limit:
6
This alarm output operates when PV value is higher than the setting value AL-H.
Absolute value lower-limit:
7
This alarm output operates when PV value is lower than the setting value AL-L.
Deviation upper- and lower-limit with standby sequence:
8
This alarm output operates when PV value reaches set point (SV value) and the value is
higher than the setting value SV+(AL-H) or lower than the setting value SV-(AL-L).
Deviation upper-limit with standby sequence:
9
This alarm output operates when PV value reaches set point (SV value) and the reached
value is higher than the setting value SV+(AL-H).

alarm output is OFF when PV value is higher than the setting value SV-(AL-L).
CT alarm output:
This alarm operates when the current measured by transformer (CT) is lower than AL-L or
13
higher than AL-H (This alarm output is available only for the controller with current
transformer).
14
When program control is end status, alarm output is ON.
15
When RAMP UP status happens to PID program control, alarm output is ON.
16
When RAMP DOWN status happens to PID program control, alarm output is ON.
17
When SOAK status happens to PID program control, alarm output is ON.
18
When RUN status happens to PID program control, alarm output is ON.
Note: AL-H and AL-L include AL1H, AL2H, AL3H and AL1L, AL2L, AL3L
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
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
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.
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.
Alarm Output Operation
: Dead Band setting of valve. The value of current valve output minus previous one must be greater than Dead Band
ON
value; otherwise, valve will remain OFF.
