A Control Area Network(CAN) is a standard interface that enables communication between the AEM-2020 and the DECS-250.The Remote Module Setup screen is illustrated in Figure 173.Figure 173. Remote Module SetupFunctional DescriptionAnalog InputsBESTCOMSPlus Navigation Path: Settings, Programmable Inputs, Remote Analog InputsHMI Navigation Path: Settings, Programmable Inputs, Remote Analog InputsThe AEM-2020 provides eight analog inputs that can annunciate a latching or non-latching alarm. Theanalog inputs are always monitored and their status is displayed on the appropriate metering screens. Tomake identifying the analog inputs easier, a user-assigned name A can be given to each input.Select the input type B. Select the amount of hysteresis Cneeded to prevent rapid switching of the alarm. Auser-adjustable arming delay Dallows configuration of the analog input threshold monitoring in one of twoways. (1) When the arming delay is set to zero, threshold monitoring is performed all the time, whether ornot excitation is enabled. (2) When the arming delay is set to a non-zero value, threshold monitoringbegins 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 ordamaged analog input wire. When enabled, Stop Mode Inhibit E turns off analog input protection whenexcitation is stopped.Ranges must be set for the selected input type. Param Min Fcorrelates to Min Input Current Gor Min InputVoltage H and Param Max I correlates to Max Input Current J or Max Input Voltage K.Each analog input can be independently configured for over or under mode Lto annunciate an alarm whenthe analog input signal falls beyond the threshold M . Alarms are configured on the Alarm Configuration,Alarms screen in BESTCOMSPlus. A user-adjustable activation delay N setting delays alarm annunciationafter the threshold has been exceeded.The remote analog inputs are incorporated into a BESTlogicPlus programmable logic scheme byselecting them from the I/O group in BESTlogicPlus. For more details, refer to the BESTlogicPlus section.BESTCOMSPlus settings for remote analog inputs are illustrated in Figure 174. Remote Analog Input #1is shown.CALL US TODAY1-888-POWER-58REQUEST A QUOTEparts@genpowerusa.comSHOP ONLINEwww.genpowerusa.comCALL US TODAY1-888-POWER-58REQUEST A QUOTEparts@genpowerusa.comSHOP ONLINEwww.genpowerusa.com
