2.1 Functions
Self-adjustment function: automatic calibration of zero point and span of the valve
Optimization of control parameters to increase control accuracy
Configuration function: valve characteristic curve, action mode, dead band, stroke range, shut-off value and alarm events
Self-diagnosis function: display of the value of the input current, runtime, dead band
Fault mode function: fail safe or fail freeze
Communication: HART communication protocol (optional)
Position feedback function: 4 ... 20 mA (actual value) - optional
2.2 Special features
Positioning precision: 0,5 % FS
Small and compact design, modular design
Automatic initialization, automatic diagnostics, valve characteristic
Fewer mechanical parts, high stability against vibrations
Local or remote parameter configuration
Low power consumption and minimum air consumption in static state, resulting in lower operating costs
Use of the 4 ... 20 mA standard signal (setpoint)
Integrated surge
2.3 Integrated lightning protection (optional)
Modern position controllers become smarter, smarter and use BUS technologies for communication as technology advances.
Therefore, it is inevitable that electronic components will be used that are more sensitive to overvoltage. In the event of
lightning, these components would be quickly damaged, which can cause the positioner to fail. Many positioners do not have a
special protection function and are therefore prone to damage due to overvoltage or lightning.
One solution to this problem is the integrated discharge circuit in the AVP-350, which protects the positioner from overvoltage.
Note
1. The lightning protection function is offered as an option.
2. The grounding must be carried out in accordance with the relevant standards, before installing the
device.
