Operating the positioner
The positioner only needs to work with its default settings. If necessary, perform a reset (see
section7.9).
An initialization procedure in progress can be canceled by pressing the rotary pushbutton.
STOP is displayed for three seconds and the positioner changes to the fail-safe position
(SAFE). Clear the fail-safe position again over Code0 (see section7.11.2).
The time required for the initialization proce-
dure depends on the actuator transit time and
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
canceled. The initialization error is displayed
accordingtohowithasbeenclassiedbythe
condensedstate.Refertosection9.

When Code 48 - h0 = YES, the diagnostics automatically start to plot the reference graphs
(drive signal steady-state d1 and hysteresis d2) after initialization has been completed. This
is indicated by tESt and d1 or d2 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.
