TC12 Installation, Commissioning & Maintenance Handbook
When the OTU detects a recognised fault the system error led is
illuminated and an entry made in the fault log. The majority of the
fault flags are set to 1 (i.e. bit 0 set) to indicate a fault, however
flags 0,1 and 2 are a special case where each bit represents a lamp
fault for a particular current sensor. Some fault flags have further
information available in the fault data array that can be accessed
using the GLD command.
