8.6.7 Period T (PERIOd T)
Period T indicates the positioner
’s internal control time interval. As default, positioner will check
current position respective to current input signal in every 100 msec.
8.6.8 Auto DZ (AUTO dZ)
After the auto calibration, the positioner will create deadzone automatically. However, depending on
the valve’s period of use, hunting or oscillation may occur due to packing friction or other reasons
and this function stabilizes the valve by detecting them automatically and increasing the deadzone at
the time of its occurrence. This will stabilize the valve but deadzone is increased.
