h. Program configuration notes
Basic parameters: Sn, Ctrl, OP1, OP2
Sn, Ctrl, OP1, OP2 are the basic four parameters. They have great impact on other
parameters. Therefore, we should set these four basic parameters first, according to the
specific requirements.
Output parameters: OP1, OP2, Hct.Cct
When setting OP1 and OP2, be sure to choose the right output module. If the output
module is a relay, logic level module or SCR zero module, then OP1 should be set at
Time proportion output. If we choose circuit output module, the OP1 should be set at
4-20mA or 4-20mA output.
When we choose time proportion output, we should set Hc,t.cc,t. If we choose
SSR(solid-state relay) or SCR zero module, the action period can be set at 2s; if we
choose relay to output, the action period should be no less than 20s.
Regulation parameter: ProP.ln
と
,
と
,dEr,
と
,rEL.C
ProP, ln
とと
,dEr
と
, rEL.C are the four regulation parameters, directly affecting
control precision.
Only if the system is heating or cooling, rEL.C displays.
In the process of PID self-setting, the system can only set ProP, ln
とと
and dEr
と
.
The cooling parameter rEL.C should be set by hand.
If the adjust method is set at positioning adjustment, ProP is the difference of positioning
adjustment.
When Pbd is set at C-F, the unit of ProP is Celsius or Fahrenheit; when Pbd is set at Pct,
the unit of ProP is %, and then the heating area equals ProP multiplied by the heating
proportion coefficient PH-L. The greater the cooling coefficient, the greater the cooling
output power. The cooling output power equals the temperature difference divided by
heating proportion,then mutiplied by cooling coefficient.
Control mode parameter Rc
と
When Rc
と
is set at rEu, the control mode is reverse-acting control. It means that as
the input signal of the meter increases, the adjustment output decreases. For example, in
heating control system, when the temperature rises, the output heating power should
decrease, so we choose reverse-acting control.
When Rc
と
is set at rEu, the control mode is positive-acting control. It means that
as the input signal of the meter increases, the adjustment output increases. For example,
in heating control system, when the temperature rises, the output heating power should
increase, so we choose positive-acting control.
