▶
LSP = LOW SP, MSP = MIDDLE SP, HSP = HIGH SP, NPV = NOW PV, NSP = NOW SP
▶
LD = LOW deviation, HD = HIGH deviation, T = ON/OFF signal
▶ ON/OFF signal operation according to PV
Setting
ON/OFF signal operation
① NPV < LSP
▶ always : OFF
② LSP ≤ NPV < MSP
▶ NPV ≥ NSP – LD : ON
▶ NPV < NSP – LD
::
: OFF
③ MSP < NPV ≤ HSP
▶ NPV ≥ NSP + HD : ON
▶ NPV < NSP + HD
::
: OFF
④ NPV > LSP
