Setting “0” will turn the judgment on loop abnormality OFF
0
A function that detects the abnormality in Output 2 loop.
・
It detects “PV Variation” per “LoP2” time.
It detects “Loop Abnormality” if the value is less than “PS2.”

Setting "0" will turn the judgment on loop abnormality PV
variation OFF
0
A function that detects the abnormality in the control loop.
If tS2 satisfies the threshold value, the judgment on the following loop disconnection takes place:
・
It detects “PV Variation” per “LoP2” time.
・
It detects “Loop Abnormality” if the value is less than “PS2.”
・
If PS2 = 0, only the judgment on time by LoP2 will be performed. If the time duration in which tS2 satisfies the threshold
exceeds LoP2, then it detects “Loop Abnormality.”
