Fault Logging

The unit maintains a time-stamped 200 event fault log in non-volatile memory, this include event acceptance
and clearance, and user logging in and out times. The non-volatile memory has an endurance of greater
than 100,000 cycles.
To prevent intermittent or frequently recurring faults from rapidly causing excessive write operations to the
memory, faults are latched so that a recurring fault is logged in its first instance, and thereafter any
repetitions are not recorded, unless a physical manual fault 'clear' has taken place.
Note that the fault log is continuously checked, and, if it is found to be corrupted, it is erased and a new 'LOG
CLEARED' fault is logged. A manual fault log clearing function is also provided.
It is possible to view a log of all faults logged by the VAR8-ACU. Multiple faults can be examined by scrolling
through the list by means of the front panel keys or rotary encoder.
