Honeywell EC350 User Manual

5.4 Alarms
EC350 monitors a list of parameters and compares their measured values to configurable limits to
determine if a fault condition has occurred. When any of these measured parameters has exceeded their
respective limit, EC350 will create an Alarm.
EC350 currently supports monitoring eight (8) parameters and supplies an Alarm Item for each. Shown
below are the eight Alarm Items.
