Alarm Log Logi
c: If Alarm Auto Clear is enabled,
the system wil
l not log the same alarm twice. For
example, if th
e system fluctuates between low flow
(F2) and acce
ptable flow, the system will log this
error only on
ce, to keep the log from filling up before
the operator
corrects the condition.
If Alarm Auto Clear is not enabled, each alarm will
log only once if the operator corrects the condition
and then clears the alarm. The alarm will log twice
if the operator clears the alarm before correcting the
condition.
The following table explains the error type that is
