Easy and quick auto-calibration
Quick auto-calibration by pushing one button provides optimal positioner setting easily and fast.
Improved display (Advanced diagnostics option)
ASD positioner has a wide display with high visibility and it’s possible to re-size information with 3 steps and available to show control graph on LCD.
Multi-lingual display (Advanced diagnostics option)
English, Chinese and Korean are available on LCD and more languages are planned to add through a continuous update.
Self-diagnostics
Advanced self-diagnostics is performed with pressure sensors installed inside of ASD positioner and results from self-diagnostics can be shown on LCD or transmitted over communication according to NAMURT NE107 standard.
Offline diagnostics (self-diagnostics)
•Loop current failure
•Loop voltage failure
•Supply air failure
•Auto calibration failure
•Position high / low limit
•Temperature high / low limit
•Supply air high / low limit
•Not calibrated
•Use small angle
•Deviation error
•TUNE-point adjust error
•PST Failure
•Use SHAPE parameter
•Valve friction high
•Check EMI / RFI
Online FDT DTM ( Device Type Manager)
It’s possible to make use of advanced of ASD positioner by using an online DTM
Available only with HART communication option
Online Diagnostics
• Valve signature (Advanced diagnostics option)
Valve signature is the result which records air pressure change and valve position according to ramp input signals. The following values about performance of valve control are obtained from this valve signature and it’s possible to confirm a current valve status(integrity)
a. Seating force
b. Friction
c. Spring range
• Valve step response
This is the result which shows a valve control status with on-off signals or on every 25% step.
a. Full stroke test
b. Normal step test
c. Large step test
d. Small step test
e. Trace test
• PST (Partial Stroke Test)
This is the function which records changes by operating the positioner with the set values automatically without influencing system in an automatic control mode.
It’s possible to confirm a valve status(integrity) by comparing the past one with the present one.
