The Armada Technologies GFL3000 Ground Fault Locator is designed to find wire or cable damage that results in an electrical path to ground. The GFL3000 works on the principle of earth gradient theory and is sometimes referred to as an earth gradient fault detector. The GFL3000 will pinpoint the exact location of a grounded cable fault. The GFL3000 is NOT a cable path locator. You will likely need a separate cable locator to locate the path of the entire cable.
How it Works – The GFL3000T transmits a voltage charge in succession approximately every 2 seconds. The charge is applied through the leads and into the connected cable where they travel to the ground fault. At the ground fault, some of the electrical current leaks to earth ground. This amount is
The receiver/A-frame is then inserted into the ground along the path of the wire. As the current flows down the wire, it travels out through the ground fault and then back to the ground stake. Some of this current, however, travels through the A-frame receiver. The needle at the top of the A-Frame will give a directional kick either left or right. The initial kick direction is the one that determines the direction. Usually after this intial kick, the needle will rebound in the opposite direction. Only the initial kick is important.
The receiver determines which side of the frame received the current first and therefore, which direction the fault lies. By relocating the frame, the user can zero in as to exactly where the fault lies.
Batteries – The GFL3000 transmitter uses a 12v rechargeable battery (included). There are also 110v AC and cigarette lighter rechargers included for this battery. The battery comes disconnected in shipping. To connect the battery, remove the finger screws located on each side of the transmitter control panel. Inside the compartment, you will see the battery and 2 connecting terminals using spade clips. Carefully remove the rubberized terminal covers and connect the spade clipped wires to the battery. Replace the cover and tighten the screws.
To recharge the transmitter battery, connect the charger to the charging receptacle on the transmitter and then plug into a wall outlet. The battery level indicator on the transmitter face will indicate the amount of charge in the battery.
The receiver module that sits atop the frame requires (1) 9V battery. Remove the screws on each side of the receiver and remove the cover. Tightly connect the 9v square battery to the battery boot and replace the cover.
