6. SYSTEM DIAGNOSTICS
The 8000 Series System diagnostic requirements will depend upon client
requirements. The recommended minimum diagnostics are included in the
Software manual. Whilst some alarms indicate a fault on the module (which require
replacement), others are used for analysis of the 8000 Series
System and indicate
a fault in a secondary component.
6.1 TEMPERATURE ALARMS
Each module has dedicated monitoring points for temperature. A high temperature
may indicate a faulty fan unit.
6.2 POWER SUPPLY UNIT
Redundant or N+1 configuration tolerates the loss of a power supply unit. A Power
supply fault is annunciated via status contacts from the power supply to inform the
operator that a power supply needs replacing.
6.3 FEED FAILURE
Should a system feed fail, and the two power feeds are isolated up to the 8000
Series
System, all three slice LED’s flash red on all modules.
