【Ex.1】Initial Conditon:1.LVL=2.LVL=FR-H, RDV=OFF
【예2】 LEVEL PID : FR-L ‹ 1.LVL ‹ 2.LVL ‹ FR-H, RDV = ON
【Ex.2】 LEVEL PID: FR-L‹ 1.LVL ‹ 2.LVL ‹ FR-H,RDV=OFF
1) Time unit of NP200 is determined by TIME parameter.
2) hh.mm refers hour(s) and minute(s) respectively while mm.ss refers minute(s) and second(s) respectively.
3) Changing TIME parameter will not affect other parameters.
4) Changing TIME parameter will affect other parameters as below :
•PRG Group: n.WTM, n.TM, nTS ON TM, and n.TS OFF TM
•PTEND Group: END.TM

PID3 is selected within a
range of 2.LVL~FR-H.
PID1~3 is selected within a range of
SP-RDV ≤ PV ≤ SP+RDV.
If SP-RDV › PV or SP+RDV ‹ PV,
PID-4 is selected.
PID2 is selected within a
range of 1.LVL~2.LVL
PID1 is selected within a
range of FR-L~1.LVL.

PID-1 Group is selected within a full range of
FR-L~FR-H because 1.LVL=2.and LVL=FR-H
PID-1 is selected within a full
range of FR-L~FR-H.
※ PID 4 is not selected because RDV is turned OFF.

PID-3 is selected within a range of 2.LVL~FR-H
PID-2 is selected within a range of 1.LVL~2.LVA
PID-1 is selected within a range of FR-L~1.LVL.

※ PID4 : If RDV is temporarily out of a specified range, the operation is corrected by PID-4.
If correction fails, the control is made by relevant PID NO.
