When the setting of the Level PID differential gap is set larger than the half of the
range between two continuous Level set values, the Level PID differential gap is
forcedly limited to the half of the range between the two relevant Level set values.
[Example] When Level PID
differential gap is “40
C
”
Autotuning (AT) at Level PID
Autotuning (AT) can be started even while Level PID function is used whether or not
the Level PID action selection is “Switching by SV” or “Switching by PV”. Autotuning
(AT) will be executed at the Set value (SV) when it is initiated.
The calculated PID values are stored in the memory area which has the Set value
(SV) at the time of Autotuning (AT) start.
[Example]
Level PID at Differential temperature control
When the Level PID action selection is “Switching by Set value (SV)”:
Level PID is done at the Input 1_Monitor Set value (SV)*.
* Input 1_Monitor Set value (SV) = Input 2_Measured value (PV) + Set value of Differential
temperature input
When the Level PID action selection is “Switching by Measured value (PV)”:
Level PID is done at the Measured value (PV) Input 1.
The Level PID will not work at the Set value (SV) or Measured value (PV) of the
Differential temperature input.
