Hi,
This clarification on the requirement of manual override for ASC, at first, should be performed by who has designed/prepared the P&ID and control philosophy of the mentioned compressor...then try asking them to clarify...

Hi,
The manuel override is required during the start up preparation of the expander and is part of the start up procedure required by the manufacturer in order to be sure that the surge valve is fully open and then the controller should be put back on auto mode before start up.

Thanks Ankur.
Thanks all for our responses.
This was a requirement from FEED Datasheet, hence thought to retain it b4 understanding is clear.
MFR doesnot know what it is
Well Ankur.
Is that has to do anything with the Calibration of Antisurge valve and its associated instruments.
Like we take the ASV Control alve in manual mode and once Calibrated then to Auto Mode.
If it is ok to discuss..
Thanks,
