Important
The prerequisite for proper operation of the TZIDC-220 positioner on the
bus is that the Transducer Block can change over to AUTO mode. This
requires that the operating range of both the positioner and the valve be
matched to each other (as described in step 5 of the procedure below). If
this auto-adjustment should fail or cannot be performed for any reason,
the Transducer Block remains in “Out of Service” mode and the configu-
ration bit in the “BLOCK-ERR Parameter” is “active”.
IMPORTANT
The positioner should be mounted/adjusted in such a way that the por-
tions of the sensor’s operating range above and below the center point
are nearly identical. Make sure to use the rotation angle of the position
sensor in the positioner to its utmost extent. Refer to
chapter 3.1 "Me-
chanical mounting"
for details about how to readjust/correct if required.
