Deviations and Advisories
Description
Alarm Log Logic: If Alarm Auto Clear is enabled,
the system will not log the same alarm twice. For
example, if the system goes back forth between low
flow (F2) and normal, the system will log this error
only once, 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
associated with each error code and icon.
How to Correct and Clear

Setup Screen 1, page
