Symbol Description
Operation or access is restricted.
Control loop is active.
The symbol is displayed when the positioner is in operating
mode 1.0 CTRL_ADP (adaptive control) or 1.1 CTRL_FIX (fixed
control) at operating level. On the configuration level there are
test functions for which the controller will be active as well. The
control loop symbol will also be displayed when these functions
are active.
Manual adjustment.
The symbol is displayed when the positioner is in operating
mode 1.2 MANUAL (manual adjustment within the stroke range)
or 1.3 MAN_SENS (manual adjustment within the measuring
range) at operating level. At configuration level, manual
adjustment is active when setting the valve range limits
(parameter group 6 MIN_VR (min. of valve range) and 6 MAX_VR
(max. of valve range)). The symbol will also be displayed when
these parameters are being set.
The configuration icon indicates that the positioner is at the
configuration level. The control operation is inactive.

Menu levels

The positioner has two operating levels.
Operating level
On the operating level the positioner operates in one of four
possible operating modes (two for automatic control and
two for manual mode). Parameters cannot be changed or
saved on this level.
Configuration level
On this level most of the parameters of the positioner can be
changed locally. The PC is required to change the limit values
for the movement counter, the travel counter, and the user-
defined characteristic curve.
On the configuration level the active operating mode is
deactivated. The I/P module is in neutral position. The
control operation is inactive.
NOTICE
Property damage
During external configuration via a PC, the positioner no
longer responds to the set point current. This may lead to
process failures.
• Before any external parameterization, always move the
actuator to the safety position and activate manual
adjustment.
