Page 29: List Of Alarms
LIST OF ALARMS There are three types of alarm resets: — Auto: automatic, when the event causing the alarm stops, also the alarm disappears. — Manual: manual, to restart normal operation manual acknowledgement is necessary. — Semi-auto: semi-automatic, the alarm is automatic but if it is present more than “n” times, it then becomes manual. The interventions are decreased by one unit every hour. Furthermore, there is a “timeout”, after which the alarm becomes manual, even if the maximum number of interventions is reached. - Page 32 SCARICA L’ULTIMA VERSIONE: DOWNLOAD THE LATEST VERSION: TÉLÉCHARGER LA DERNIÈRE VERSION: A E R M E C S . p .
