4. Enstalasyon
4.1. Enstalasyon batri
The 521E system requires batteries for both the transmitter and receiver. Batteries are not included.
- Transmitter (521-T): Requires six (6) 1.5V D-cell alkaline batteries. Open the battery compartment on the underside of the transmitter and insert the batteries, observing correct polarity.
- Receiver (521E-R): Requires four (4) 1.5V AA-cell alkaline batteries. Open the battery compartment on the handle of the receiver and insert the batteries, observing correct polarity.

4.2. Receiver Assembly
Attach the carbon fiber reinforced rod to the receiver handle by screwing it into the designated port until secure.
Figure 4.2: The 521E Receiver with the carbon fiber rod attached.
4.3. Konekte transmetè a
The transmitter sends a signal through the wire you wish to locate. Connect the transmitter leads as follows:
- Connect the red lead to the wire you want to trace.
- Connect the black lead to a good ground source, such as a metal stake driven into the earth, a cold water pipe, or the neutral wire of a power source (if safe and appropriate for the application).
- Ensure all connections are secure to establish a clear signal path.

5. Operasyon
The 521E locator tool is designed for accurate and efficient tracing of buried wires, irrigation valves, and cable faults.
5.1. Powering On and Signal Adjustment
- Turn on both the transmitter and receiver. The large, sunlight-compatible LCD displays will illuminate.
- Adjust the signal level on the transmitter as needed. A higher signal level may be required for deeper or longer wires.
- Connect the HS-1 Headset to the receiver for clearer audio feedback, especially in noisy environments.
5.2. Wire Tracing
To trace a buried wire:
- With the transmitter connected and powered on, hold the receiver with the carbon fiber rod pointing towards the ground.
- Walk slowly along the suspected path of the wire. The receiver will provide visual and audio indications of the signal strength.
- The signal will be strongest directly over the buried wire. Follow the path where the signal is maximized. The receiver's ergonomic design allows for comfortable one-handed operation.
Figure 5.1: Demonstrating the use of the 521E Receiver for wire tracing.
5.3. Depth Determination
The 521E features a 45-degree angle indicator for determining wire depth:
- Once the wire path is located, hold the receiver at a 45-degree angle to the ground, directly over the wire.
- The 45-degree angle indicator on the display will light up when the receiver is within 3 degrees of the correct angle.
- The depth of the wire can then be triangulated within 10% accuracy.
5.4. Fault Finding and Valve Location
The 521E is effective for locating underground wire breaks, large nicks, and solenoid valves:
- When tracing a wire, a sudden drop or loss of signal can indicate a break or fault.
- For valve location, trace the control wire to the area where the valve is suspected. The signal will often change or become more localized directly over the valve.
- The receiver's triple-stage filtering helps provide a clearer signal, allowing for visual identification of subtle signal changes to pinpoint splices, wire damage, or decoders.
6. Antretyen
6.1. Ranplasman batri
The typical battery life for both the transmitter and receiver is approximately 50 hours. Replace batteries promptly when the low battery indicator appears on the display to ensure optimal performance.
6.2. Netwayaj ak Depo
- Netwaye eksteryè a nan inite a ak anonsamp twal. Pa sèvi ak pwodui netwayaj abrazif oswa solvang.
- Ensure the unit is dry before storing.
- Store the 521E in its carry case in a cool, dry place, away from direct sunlight and extreme temperatures.
- Retire pil yo si ou pa pral itilize aparèy la pou yon peryòd tan pwolonje pou anpeche flit.
NAN. Depanaj
If you encounter issues with your 521E locator tool, refer to the following common problems and solutions:
| Pwoblèm | Kòz posib | Solisyon |
|---|---|---|
| Aparèy pa limen | Pil ki mouri oswa ki mal enstale. | Tcheke polarite pil yo epi asire w pil yo fre. Ranplase yo si sa nesesè. |
| Weak or no signal detected | Poor transmitter connection, low transmitter battery, wire too deep, or signal interference. | Ensure transmitter leads are securely connected to the target wire and a good ground. Replace transmitter batteries. Increase transmitter signal level. Reduce interference from other electrical sources. |
| Inaccurate wire tracing or depth readings | Improper technique, environmental factors (e.g., wet soil, metallic objects), or signal interference. | Review operation instructions for proper tracing and depth determination techniques. Be aware of surrounding metallic objects. Practice in a known area. |
| Intermittent signal or erratic readings | Loose connections, damaged wire, or strong external electrical noise. | Check all connections. Inspect the wire for visible damage. Move away from known sources of electrical interference. |
