Operating the positioner
The time required for the initialization proce-
dure depends on the actuator transit time,
which means that initialization can take a few
minutes.
After a successful initialization, the positioner
runs in closed-loop operation indicated by the
closed-loop operation icon.
A malfunction leads to the process being can-
celed. The initialization error is displayed ac-
cording to how it has been classified by the
condensed state. Refer to section 9.

When Code 48 - h0 = YES, the diagnostics automatically start to plot the reference graphs
required for the valve signature after initialization has been completed. This is indicated by
TEST and D1 appearing on the display in alternating sequence.
An error during the plotting of the reference graphs is indicated on the display over Code 48
- h1 and Code 81. The reference graphs do not have any effect on closed-loop operation.
Fail-safe action AIR TO CLOSE
If the slide switch is set to AIR TO CLOSE,
the positioner automatically switches to the
direction of action increasing/decreasing
(
äæ
) after initialization has been complet-
ed. This results in the assignment (left) be-
tween set point and valve position.
The tight-closing function is activated.
