9.6.5 - Fans and pumps drive alarms/alerts
Fan drive alarms or alerts are displayed based on the
following formula:
• 20-YYY to 25-YYY (20=A1, 21=A2, 22=A3 and
23=B1, 24=B2, 25=B3) for alarms
(YYY stands for the alarm code)
• 38-YYY to 43-YYY (38=A1, 39=A2, 40=A3, 41=B1,
42=B2, 43=B3) for alerts
(YYY stands for the alert code)
