Industry Association in conjunction with the N E C National Electrical Council have established rules regarding the rating of electrical systems and the use of energy management systems One of these rules requires that if an energy management system is used the average total load current for the system over a 3 hour period be limited to 80 of the service rating For that reason the 50 amp EMS calculates the average running current for the system and if itexceeds 8096 ofthe service rating the EMS sheds loads to reduce the average current below that limit For example if a system operating under 120 VAC 30 Amp service has been running at the 30 Amp limit for three hours the EMS will change its shedding threshold to 24 Amps and turn off loads until the 24 Amp limit is attained If the user selects the 20 Amp service mode this limit will translate to 16 Amps Because the EMS calculates a running 3 hour average if the average load current drops below the limit the system will restore power to loads based on their impact on the limit If the System is in the Averaging mode the decimal point at the lower right corner of the Load Meter display on the Display Panel will illuminate DISPLAY PANEL 50 AMP SERVICE TYPE SMART EMS POWER STATUS GEN SET AC LINE FIRST SHED 50 MEM AMP NEXT SHED 30 EV 30 NEXT SHED 20 EU NEXT SHED 30 20 AMP ta SELECT LOAD METER NEXT SHED LAST SHED by Mfintellitec POWERED WHEN LIT The Display
