• Proportional control is that an outout capacity regarding a setting value(SV) is proportionally operated by a
deviation. the width which the output is varied within 0~100% is called proportional band(PB). therefore, for reverse
action, if PT=present(process) temperature, PB=proportional band
• PT＜PB→Output capacity 100%, PT＞PB→Output capacity 0%, PT=PB→Output capacity 50%
※ PT : Present(process) temperature, PC : Proportional cycle, SV : Setting value(temperature), PB : Proportional band
• This is a control method that if PT is higher than SV then output will be OFF or if PT is less than SV, then the output
will be ON, also, it is called 2－position control since it outputs either 0% or 100%. the status which the
temperature is unstable and there is high/low wave around SV is called hunting. the width between the point
where its output is OFF because PT is higher than SV and the point where its output is ON since PT is less than
SV is called adjusting sensitivity, hysteresis. if the width, hysteresis, is narrow, then high/low wave becomes
smaller but the cycle of ON-OFF gets smaller so that it may severly damage to electromagnetic switch,
electrovalve or etc.. especially, for controlling burner which is using freezer or electrovalve, 2－position control
is generly used.
※ PT : Present(process) temperature, SV : Setting value(temperature)
• For proportional control : if the proportional band(PB)
is narrow, then the output's variable width will
become smaller so that the time which the controlling
temperature(PT) is approaching to SV* is fast. also,
OFF－set(deviation)becomes small. however, if PB* is
too narrow, then there is over shoot or hunting, PB*
can be set within the max range of 1~10%. if turn the
PB volume in clockwise then PB* gets larger. if turn
the PB volume in counterclockwise then PB gets
smaller.
• For ON－OFF control : for the case of selecting ON－OFF
control, the adjusting sensitivity is varied within the
max range of 1~10% by the PB volume.
• For proportional control, when the controlling
temperature(PT) and SV* are the same, it generates
50% of output so that there is constant error(normal
deviation) by heat capacity or etc. of a controlling
target. to eliminate this matter, change the output
capacity by reset volume.
• Display value ＜ setting value : turn the volume in
clockwise.
• Display value ＞ setting value : turn the volume in
counterclockwise.
• Output : Example of ON/OFF+ON/OFF operation
※ PT* : Present(process) temperature,
PC*: Proportional cycle,
SV* : Setting value(temperature),
PB*: Proportional band
• It is depending on its specification code when you are ordering.
