Operating modes
The positioner can be operated in "manual" and "automatic" mode. This results in a variety
of operating options. These differences, as well as changing from one operating mode to the
other, are described below.
Automatic mode
"Automatic" is the commonly-used operating mode. In this operating mode, the positioner
compares the setpoint position with the actual position. The positioner moves the actuator
until the actual and setpoint value correspond, or until the deviation reaches the
parameterizable deadband. If it is not possible to reach the deadband, an error message is
provided. It is not possible to manually move the actuator.
Manual mode
Note
Failure of power supply
Once the power supply returns, the positioner switches into automatic mode.
In manual mode, you move the actuator with
maintained regardless of the setpoint current or occurring leakages.
