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.
