6 Alarms
The UC protects the unit and the components from operating in abnormal conditions. Protections
can be divided in preventions and alarms. Alarms can then be divided in pump-down and rapid
stop alarms. Pump-down alarms are activated when the system or sub-system can perform a
normal shutdown in spite of the abnormal running conditions. Rapid stop alarms are activated
when the abnormal running conditions require an immediate stop of the whole system or sub-
system to prevent potential damages.
The UC displays the active alarms in a dedicated page and keep an history of the last 50 entries
divided between alarms and acknowledges occurred. Time and date for each alarm event and of
each alarm acknowledge are stored.
The UC also stores alarm snapshot of each alarm occurred. Each item contains a snapshot of the
running conditions right before the alarm has occurred. Different sets of snapshots are
programmed corresponding to unit alarms and circuit alarms holding different information to help
the failure diagnosis.
