Alarm Log Logi

the system wil
l not log the same alarm twice. For
example, if th
e system goes back forth between low
flow (F2) and n

only once, to
keep the log from filling up before the
operator cor
rects 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.
