The AEM-2020 provides eight user-configurable RTD inputs that can annunciate a latching or non-
latching alarm. The RTD inputs are always monitored and their status is displayed on the appropriate
metering screens. To make identifying the RTD inputs easier, a user-assigned name
A
can be given to
each input.

user-adjustable arming delay
D
allows configuration of the RTD input threshold monitoring in one of two
ways. (1) When the arming delay is set to zero, threshold monitoring is performed all the time, whether or
not excitation is enabled. (2) When the arming delay is set to a non-zero value, threshold monitoring
begins when the arming delay time has expired after system startup is complete. An out-of-range alarm,
configured on the Alarm Configuration, Alarms screen in BESTCOMSPlus, alerts the user of an open or
