I need your technical suggestions to rectify the below problem, I would like to brief here shortly.
When we commissioned the RTHD chiller with solid state starter ( Chaina make) chiller it was running in good condition almost 18 hours after that it is started tripping in momentary power loss.
We have disabled the MPL then it is started tripping in power loss after 10-12 minutes of running.
Checked all the external controls, Para meter settings of dyna view & SSS & cabling of the chiller related all power loss problems.
Changed CT, PT, starter module, Power module, dyna view, put the loop for HP cutout, by passed disconnect switch, replaced SS Starter, incoming power analysis, connected separate cable from adjacent chiller, voltage sensing option disabled, checked water flow, bypassed the flow switch & disabled all the power related settings even though same problem (tripping after 10 -15 minutes)
After these exercise we have opened the compressor checked slide valve movement found to be okay, currently our team is checking the terminal status
If you have any more technical suggestion pls. advice.
