@@instrumentationandsolution5013 checked in 1.1 it's working fine and also able to operate in local mode. Only in remote mode it's not operating. ps. it's a profibus PA device
U can reduce hunting (permanently) by calibrate I/P ... plz check my I/P calibration video. And u can reduce hunting through parameters, go to parameters no 7 and reduce deadband to 0.1 and u can do PID adjustment in parameters increase (7, 7.1,) parameters.... hunting will reduce
@@instrumentationandsolution5013 deadband and gain of abb is already done but still there is a hunting . I tell u if we close or fully open there is no hunting but if we do 25%,50% or 75% hunting start .help me plz sir
@@shaktisingh4793 for how many seconds it's hunting or continuously hunting, generally if u give command 0 to 25 to 50 to 100 its will hunt for 2 to 3 seconds, if it's hunting more that 2 to 3 seconds then plz check following 1. Any play in Feedfack link , 2. did u checked I/P passing or not, 3. Check any leakage in actuator, 4. Check gland tightness, 5. U can reduce hunting by changing P 7.8 deadband approach fast to medium etc ....
@@AnilKumar-xo7ot more than 3 sec it do hunting .feedback link is checked,deadband parameter is reduced to 0.1 ,gland tightness is also checked ,there is no leakage . What else i do sir ?

sir i ues auto adjust and run 20 outlet no have any air come out how to do ?? can repair or no??
U can adjust I/P... Plz check my I/P adjustment video...
Positioner is not taking Setpoint/ demand from remote DCS... Able to operate locally... What can be the issue
Keep positioner operating mode to 1.1 ..
Check the feedback cable and current mA cable once ... Sometimes cable can be interchanged ...

Check the address in the positioner ..
Sir how can we overcome haunting problem in ABB positioner ?
