The GT frame 6b and the control system is MARK VI TMR unit was tripped from the HVAC short circuit. This kind of events had happened twice this year. VPRO and S controller shown power supply fault.
This unit has only one 110VDC supplied to the power distr. What are the possible causes of the trip?
- Please advise how to prevent this
- Can the PDM and VPRO limits of the lower/over voltage input be adjusted?
- Would it be solved by adding AC power supply to PDM?
Would it help to install AC through DACA?
- Can the HVAC panel be moved to the 110VDC main bus bar?
Please advise
