voltage spikes and surges nature has a way of occasionally creating electrical forces that are beyond the capabilities of any device
to absorb without some degree of damage. In the rare instance that this occurs and the DCS circuit has been damaged, the Red
“ACFault”LEDindicatorwillilluminateandaninternalbuzzerwillsound.TheETA-ECS3willalsoshutoffpermanentlyuntilthe
unit is repaired. Note: If the AC Fault LED is illuminating it is important to have all equipment that was connected to that AC
Mains Line inspected for proper operation.
12. AC Mains Abnormal Voltage Indicator–ThisLEDflashesunderseveralACMainsfaultsituationsthatarelistedbelow.Normal
operating voltages for AC Mains voltage is considered to be between 108VAC and 125VAC. Any voltages exceeding those
parameters are considered a risk to damage equipment plugged into the ETA-ECS3.
High AC Line Mains–TheAbnormalVoltageLEDwillflashbetween128VAC–132VACindicatingpossibledamagemayoccur
to equipment due to high AC Mains voltage. The ETA-ECS3 outlets will remain active but the LED will stay flashing even if the
voltagereturnstoanormaloperatingrange.TostoptheLEDfromflashingthesystemactivationswitchmustbecycled“Off”.
Note: It is recommended prior to proceeding to have the AC Mains inspected by an electrician.
Low AC Line Mains–TheAbnormalVoltageLEDwillflashbetween101VAC–107VACindicatingpossibledamagemayoccur
to equipment due to low AC Mains voltage. The ETA-ECS3 outlets will remain active but the LED will stay flashing even if the

Extreme High AC Line Mains–IftheACMainsreach132VAC,theEVS(ExtremeVoltageShutdown)circuitwillbetriggeredto
shut off the AC outlets while activating the Abnormal Voltage LED. The Red LED will illuminate steady and the AC Mains Voltage
Meter will flash OL (Overload), indicating possible damage may occur to the equipment plugged into the ETA-ECS3 due to high
ACMainsvoltage.TheETA-ECS3outletswillremainoffuntiltheSystemActivationSwitchiscycled“Off”.

to shut off the AC outlets while activating the Abnormal Voltage LED. The Red LED will illuminate steady and the AC Mains
Voltage Meter will flash OL (Overload), indicating possible damage may occur to the equipment plugged into the
