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.
