NOYAFA NF-817 (01) PDF MANUAL

Parts Included:

1 x Wire Locator Transmitter

1 x Wire Locator Receiver

1 x Premium Durable Case

Note: The underground wire locator is ideal for users to trace low voltage cables. It is not recommended that unqualified people use this equipment to trace cables that are above 32 Volts.

(Requires 2 x 9V Batteries)

Read and understand this material before operating or servicing this equipment. Failure to understand how to safely operate this tool could result in an accident causing serious injury or death.

The underground wire locator is suitable for use on Un-energized or Low voltage installations only.

At no time should this device be used on utility mains powered devices or cabling connected to the utility mains! If in doubt do not use this device and call in a suitably qualified electrical contractor.

The underground wire locator is designed to allow the user to track low voltage cables used for garden and landscape automatic watering systems, and also low voltage garden lighting systems.

It can also be used to trace other metal cables.

The system uses a “transmitter” to send a signal down the cable being traced or to a solenoid valve that is being located.

A “receiver” is then used to pick up the signal and follow the cable or locate the coil.

Firstly long press the power button to turn on the device, push the toggle button of emitter to “polar” position, then use the clips to connect the two sides of battery with the two clips. If the indicator “polar” is green, it means that the red clip connects positive pole, the black clip connects negative pole. If the indicator “polar” is red, it means that the red clip connects negative pole, the black clip connects positive pole.

To locate a cable follow the following procedure:

1) Connect the transmitter to the cable you are looking for. If the cable is connected to an irrigation controller, Disconnect the cable from its normal power source and clip the RED alligator clips from the transmitter onto the cable.

2) There are several options for connections of the black alligator.

2.1) to a blade of a screw driver pushed into the ground (preferably wet ground), you might require to connect via a short length of cable.

2.2) to the ground wire.

2.3) to Nothing, just let the black alligator clip dangle in the air.

3) For NF-816, Move the transmitter switch to the “Cable scan” position. For NF-817, firstly long press the power key to turn on the transmitter, then shift the function switch on the top-left side to “SCAN” mode.

Once the transmitter is attached to the cable and the ground or common as in “B” above, ensure the transmitter switch is in the “Cable Scan” position and turn the “Thumb Wheel” switch to high tone.

Locate approximately the route of the cables and swing the receiver antenna in a pendulum type action at right angles to the cable path starting at least 3 meters away from the transmitter.

As the receiver antenna swings past the underground cable, a tone will be heard on either side of the cable path, when you are right over the buried wire, you’ll get a gradual increase in the tone and hear the loudest sound.

You can adjust the transmitter and receiver controls to move further distances according to your wire depth.

You can also use the ear phones to assist with the detection.

A cable break will be detected by the loss of signal in the receiver antenna.

To locate other wires, it is best to disconnect the wire in question and directly attach only one transmitter lead to the subject wire, letting the other lead hang. Trace the path as outlined in point ‘C’ (Locating & Tracking Buried Irrigation Wires).

Once the path has been determined, mark the ground at a null point along the path.

Hold the Receiver antenna at a 45-degree angle to the ground and move at a right angle away from the path of the wire until another null is found. Mark this point. The distance between the two marks is the approximate depth of the wire.

Setup the Transmitter as described in (Fig.01).

Locate and mark the path of any signal near your drill site. If you have reason to believe that other installations are present near your drill site, use the procedures outlined in section ‘C’ (Locating & Tracking Buried Irrigation Wires).

The signal generated by the Transmitter can be detected through walls and ceilings, to pin point the transmitter’s location (specific point), wrap the alligator clip leads around the Transmitter, short the leads together, turn the transmitter on and secure it to the opposite side of the wall or ceiling with tape. Scan the wall with the antenna flat against the wall. The PEAK signal will be heard when the antenna passes directly over the transmitter location.

The 3.5mm earphones can be connected to the Receiver earphone jack to improve efficiency in a noisy environment.

The user can activate the LED flash-light by pressing the ‘Push For Light’ button.

1. Slide off battery compartment cover.

2. Replace the 9V battery. Observe polarity.

3. Replace cover.

Before opening the case, remove the test leads from the circuit and shut off the unit. Failure to observe these warnings can result in severe injury or death.

Periodically wipe with a damp cloth and mild detergent; do not use abrasives or solvents.

Should you need for any reason to return the tester for repair or replacement take prior agreements with the local distributor from whom you purchased the item. Use only original packaging for any transit of shipment. The manufacturer will not be responsible for any damage to persons or things.
