Dear sir

After greeting i need to inform that i have in my plant Smarttrack for HP/IP turbine hydraulic system but i have a problem. in it this problem is floating. it suddenly happened when the bypass in service it is suddenly close. and after sometimes it is suddenly open again and flow the control signal from DCS (Ovation System). we check every thing in it signal wires, Main power supply 240VAC, feedback signals from proximaters. and we found every thing is ok. pls can u help me for solving this problem? we log in by remote control software to check the diagnostic file. and we cant identify the problem just "pos exed warn alarm" it is repeated about 128 times see the attached papers.

and i need to ask if the power fail from power supply board smarttrack it will record also in Diagnostic file? i note that the last 5 times for suddenly close date not recorded in the diagnostic file .
