Eaton HFX Series Installation And Operation Manual

EATON HFX Product Family Installation and Operation Manual E-ELCL-II002-E2 July 201953List of Battery FaultsBatt_Low – This occurs whenever the supply voltagedrops below 6 V for more than 5 seconds.Batt_High – This occurs whenever the supply voltageexceeds 32 V for more than 3 seconds.List of PWM Faults for PWM1_2A to PWM16_2APWM#_2A Loss of Control – This fault indicates thatcurrent or reverse current exceeding a default 75 mAis flowing without any commanded output current onthe channel.PWM#_2A Over Current – High-Side currentmeasured on output 1(2A) is greater than thehardware limit or greater than a default Max currentof 2000 mA. The default current values can beoverwritten in the configuration of the unit.PWM#_2A Short to battery – This fault indicateswhen output channel 1(2A) has a short to the battery.Note: That the controller is comparing commanded current valueto the measured value to evaluate for the fault. The defaultcurrent value is 25 mA but can be overwritten in the configurationof the unit.PWM#_2A Open circuit or Low-Side drive grounded– This fault indicates when there is an open circuiton output channel 1(2A). The controller is comparingthe commanded current value to the measured valueor checking for a ground short on the output. Thedefault values can be overwritten in the configurationof the unit.List of PWM Faults for PWM1_4A to PWM8_4A –Fault DescriptionPWM#_4A Loss of Control – This fault indicates thatcurrent or reverse current exceeding a default 75 mAis flowing without any commanded output current onthe channel.PWM#_4A Over Current – High-Side currentmeasured on the output (4A) is greater than thehardware limit or greater than a default Max currentof 4000 mA. The default current values can beoverwritten in the configuration of the unit.PWM#_4A Short to battery – This fault indicateswhen output channel (4A) has a short to the battery.Note: That the controller is comparing commanded current valueto the measured value to evaluate for the fault. The defaultcurrent value is 25 mA but can be overwritten in the configurationof the unit.PWM#_4A Open circuit or Low-Side drive grounded– This fault indicates when there is an open circuit onthe output channel (4A). The controller is comparingthe commanded current value to the measured valueor checking for a ground short on the output. Thedefault values can be overwritten in the configurationof the unit.HFX Product Family
