Advanced (Double Acting) Tuning Parameters
The Advanced (Double Acting) tuning parameters dialog provides two views for
comparison, the left half is the original one before changing the configuration, the right
half is downloaded to the positioner and implemented after selecting OK. Refer to
Table 11 for an explanation of parameters, which function the same as for single acting.
CAUTION Before performing Travel Calibration, check that the Tight
Shut Off, Full Open Feature and Position Limits are
disabled. If Travel Calibration is used to change zero and
span more than 10 percent then the Position limits defaults
may be incorrect. The position limits may need to be
increased or deceased.

relay, and valve.
