INSTRUCTIONS1. Run all current carrying conductorsthrough sensor windowA. Use an auxiliary CT if conductors do not fit. Con-sult Factory for CT selection.2. Mount the sensor to a surface if needed.3. Connect output & power wiring.A. Use up to 14 AWG copper wires.B. Make sure load matches the output shown on thesensors’ label.• Sensors labeled “xxAC” will only switch AC.• Sensors labeled “xxDC” will only switch DC.C. Make sure power supply matches the power inputshown on the label.4. TestA. Pressing the “TEST” button tests the sensors inter-nal circuits. CAUTION: The output and any con-nected loads will switch!AG1-NCAC-120 -FS - 005Model Number KeySpecificationsQuick “How To” GuidePower Supply NotesAG 1, 2 & 3 SERIESGround Fault SensorsAuto-ResetOutput TypeNCAC Normally Closed 1A @ 240 VACNOAC Normally Open 1A @ 240 VACNCDC Normally Closed 0.15A @ 30 VDCNODC Normally Open 0.15A @ 30 VDCNCR Normally Closed, 0.5A @ 120 VAC, 0.25A@ 240 VAC, 2A @ 30 VDCNOR Normally Open, 0.5A @ 120 VAC, 0.25A @240 VAC, 2A @ 30 VDCPower Supply24U 24 VAC/DC1 2 0 120 VAC2 4 0 132-264 VACSetpoint Range1 5-100mA, Adjustable2 80-950mA, Adjustable3 Tri-Set, 5, 10 & 30 mA, Jumper SelectAG Series Ground Fault SensorSetpoint Range AG1 Series: 5-100mA Field AdjustableAG2 Series: 80-950mA Field AdjustableAG3 Series: Tri-Set, 5, 10 & 30 mA, JumperSelectVoltage Range Up to 1,500 VAC (Monitored Circuit)Frequency Range 50-400Hz (Monitored Circuit)Output Options (See Product Label)Solid State AC Switch 1A @ 240 VAC (2A for 10 Min)Solid State DC Switch 0.15A 30 VDC (500mAmomentary)Relay Output 0.5A @ 120 VAC, 0.25A @ 240VAC, 2A @ 30 VDCResponse Time 150 mS @ 5% above setpoint.100 mS @ 50% above setpoint.Power Supply Operates from 55-110% of nominal voltageNominal Voltages 120, 240 VAC (50-400 Hz)Green LED=PowerOptional Power 24VAC or 24 VDC Operates +/- 20%Power Consumption 2.5 WattsDimensions 2.5"H x 2.8"W x 1.5"D, (64x71x38mm),aperture 0.75" (19mm) dia.

Keep in mind thatthe best way to reduce noise in a system is to suppress it at itssource.1. Keep the sensor power isolated from noisy circuits.2. Do not power the sensor with the same circuit thatswitches contactors or other high current, inductive loads.Good design practice and code require that all AC powersystems be grounded. AG Series sensors are designed towork on grounded AC power systems. They may not operateproperly on ungrounded systems.Setpoint005 to 950 Factory AdjustedSetpoint in mA (specifywhen ordering)TR3 Tri-Set, 5, 10 & 30 mA,Jumper SelectOptionsFS Normally EnergizedNF Normally De-energizedBuy: www.ValinOnline.com | Phone 844-385-3099 | Email: CustomerService@valin.com |
