Set the secondary control loop anomaly PV threshold .
The function is to detect an abnormality in the control loop.
When width of tS1 has PV from an SV , a judgment of the loop anomaly acts.
The real judgment in PS2 and LoP2.
For details, see sectionLoop abnormality function on pages 5-38 and 39.

PV
When PV is out of the judgment
domain, the control loop anomaly is
not judged.
PV indicates present temperature.
Temperature threshold is a value
specified by [SV TS2].
