SummarySummarySummary Summary • TTCS mirco-g functional test is done for the 1st loop.TTCS mirco g functional test is done for the 1 loop.• The system operated very well and passed the test.• Suggestion for control scenario (done by ground

control):)– Do not run the loop at pump speed lower than 5000RPM in

any tracker operation case.any tracker operation case.– Use the start-up heater to depress pressure spike caused by

superheating during the start-up process in nominal casesuperheating during the start up process in nominal case and cold case.
