โ๏ธ Parameter Configuration and Modification Methods
As a passive power distribution and voltage routing board, the DS200TCPDG2B does not require software programming or firmware configuration. However, physical setup and verification involve precise maintenance steps:
- ๐ป Hardware Inspection: Inspect physical jumpers, terminal blocks, and fuse configurations against engineering drawings before installation.
- ๐ Power Isolation: Ensure all primary rack power sources and external AC/DC supplies are completely de-energized and locked out prior to handling the board.
- ๐ ๏ธ Chassis Installation: Carefully align and slide the board into its designated slot within the Mark V core or VME cabinet enclosure, securing all retention screws.
- ๐ฅ Voltage Verification: Power on the system and use a digital multimeter to test output bus voltages and verify that fuse status indicators show normal operation.
๐ Manual / Automatic Mode Switching
Operational modes for power distribution modules are managed entirely by the automated power supply architecture of the Mark V control system.
- โ๏ธ Automatic Mode: The board continuously routes, filters, and distributes regulated power rails to system modules without requiring operator intervention.
- ๐ ๏ธ Manual Mode / Inspection: Physical fuse checking and voltage testing can be performed manually by authorized technicians during scheduled maintenance outages.
- ๐ Switching Procedure: No active runtime mode switching is required, as power distribution is entirely automatic based on primary rack power activation.
