OPURGE NO SETUP PARAMETER NO ALAR Alarms management Alarm page management differs from monitoring of status pages due to following details e When an alarm status begins the display shows a blinking page containing alarm information alarm page until the acknowledgement operation e After the acknowledgement the display alternates the status page to the blinking alarm page in sequence with refresh period 5 seconds The acknowledgement of the alarm page occurs by pushing the ACK pushbutton on front panel when this appears on display When more than four alarms are in progress these are shown by more alarm pages each requiring a distinct ACK acknowledgement sequence in this case the display will resume the cyclical visualization of status page and alarm pages after completing the acknowledging sequence In case a new alarm goes active when all current alarm pages are acknowledged the display stops on alarm page showing new information 10 spectr Whichever acknowledged alarm status persisting longer than the recovery time automatically returns into the unacknowledged condition and requires a new cumulative acknowledgement operation only one for all alarms pages The acoustic signal continues until unacknowledged alarm pages exist The red light signal remains alight until the alarm status exists Typical ALARM PAGE Ident 1 value 1 unl The example left shows an Alarm Pag
