AEM-2020 Configuration
AEM-2020s are enabled on the Remote Module Setup screen in BESTCOMSPlus. If more than one
AEM-2020 is connected, the serial number of each module must be entered. An AEM Not Configured pre-
alarm will occur if the expected serial number does not match the serial number detected on the General
Settings, Device Info screen. The Remote Module Setup screen is illustrated in Figure 194.

Remote Analog Inputs Configuration
Eight remote analog inputs provide metering for a variety of industrial transducers. An element can be
configured to trip when the metered input increases above or decreases below the user-defined
threshold.
The eight, identical remote analog input protection elements are designated AEM x Input #1 through AEM
x Input #8 (where x = 1 to 4). Element logic connections are made on the BESTlogic
™Plus screen in
BESTCOMSPlus ® and element operational settings are configured on the AEM x Input #y (where x = 1 to
4 and y = 1 to 8) settings screen in BESTCOMSPlus.

Label Text
In order to make identification of the remote analog inputs easier, each of the inputs can be given a user-
assigned label. The label is an alphanumeric string with a maximum of 16 characters.
Hysteresis
The hysteresis setting provides a level of hysteresis between a threshold detection tripping and dropping
out. For instance, if the hysteresis is set for 5% and the threshold is set as an over threshold, once the
threshold detection trips, the measured value must drop to 95% of the threshold before the threshold
detection will drop out. This hysteresis helps prevent rapid or repeated transitions between trip and
dropout in cases where the measured input is nearly equal to a level equal to the threshold.
