8.18 Expansion Control Setting Level (l.exc)
p-db
• This parameter is used on a Position-proportional Control Model so
that PV = SP when the PV is within the PV dead band.
• This function prevents unnecessary output when the PV is near the
SP.

cjc.*
• When using a thermocouple input, these parameters are used to
specify whether cold junction compensation is performed inside the
Controller or outside the Controller.
• Select "External" when two thermocouples are used to measure the
temperature difference or when an external cold junction compen-
sator is used for increased accuracy.
