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.
