IMPORTANT (NOTE)
Manipulation by users shall immediately render the
warranty for the device invalid.
To ensure fault-free operation, it is essential that
the device is supplied with instrument air that is
free of oil, water, and dust.
The positioner does not require any maintenance if it is used
as intended under normal operating conditions.
Description
If an external position sensor is connected, this parameter must be set to "On".
Use this parameter to select the version of the installed position sensor.
Standard – Standard position sensor
Non- Contact – Non-contact position sensor.
Once the position sensor has been replaced, the correction values used for linearizing the sensor
characteristic curve (supplied by the factory together with the position sensor) can be entered
here.
Use this parameter to set the fine adjustment of the 0° position after a sensor replacement.
Press the "Confirm" button to accept the current position as the center position of the sensor
range.
IMPORTANT (NOTE)
For this purpose, the positioner feedback shaft must be exactly in the center
position.
Use this parameter to set the alarm current for the analog position feedback. This current is
output even if the positioner is in a no-current state (external supply).
High – I > 21.5 mA
Low – I < 3.6 mA
IMPORTANT (NOTE)
In order to save the parameter in the non-volatile memory on the "analog position
feedback" module, the module must be supplied with 24 V during
parameterization.
IMPORTANT (NOTE)
Perform a functional check of the emergency
shutdown module (option) at least every 2 years.
For this purpose, the positioner must move the
valve into the safety position with the 24 V DC
signal (terminal +85 / -86) interrupted.
