SSDAC/ HASSDAC Health Monitoring

SSDAC/HASSDAC Health Monitoring

SSDAC/HASSDAC HMU receives diagnostic data from SSDAC/HASSDAC. Voltage, current & Vital relays are monitored by external sensor unit and SSDAC HMU gives diagnostic data through error codes even VR and PR are dropped. These error codes are available in the reset box. These error codes are made use in generating alarms for the maintainer.

Parameters SSDAC/HASSDAC HMU receives

Receives Diagnostic data from DAC through Serial / Ethernet ports
Voltage, current & Vital relays are monitored by external sensor unit
