Functional Description
A functional description of the AEM-2020’s inputs and outputs is provided below.
Analog Inputs
The AEM-2020 provides eight analog inputs that are user-selectable for 4 to 20 mAdc or 0 to 10 Vdc.
Each analog input has under/over thresholds that can be configured as status only, alarm, or pre-alarm.
When enabled, an out of range alarm alerts the user of an open or damaged analog input wire. The label
text of each analog input is customizable.
RTD Inputs
The AEM-2020 provides eight user-configurable RTD inputs for monitoring genset temperature. Each
RTD input can be configured as status only, alarm, or pre-alarm to protect against high or low
temperature conditions. When enabled, an out of range alarm alerts the user of an open or damaged RTD
input wire. The label text of each RTD input is customizable.
Thermocouple Inputs
The AEM-2020 provides two thermocouple inputs for monitoring genset temperature. Each thermocouple
input can be configured as status only, alarm, or pre-alarm to protect against high or low temperature
conditions. The label text of each thermocouple input is customizable.
Analog Outputs
The AEM-2020 provides four analog outputs that are user-selectable for 4 to 20 mAdc or 0 to 10 Vdc. A
wide selection of parameters including oil pressure, fuel level, generator voltage, and bus voltage can be
configured as analog outputs. Refer to Section 4, BESTCOMSPlus
™ Software, for a full list of parameter
selections.
