Product Q&A

Q:Why might communication fail?

Communication failure often occurs if the coupler's protective ground wire is grounded in the middle ground or if the protective earth wire in the hanging basket is not connected.

Q:What causes poor communication?

Poor communication can be caused by high resistance from ground wiring, poor connections, or interference from electric motors requiring better cable shielding.

Q:Do I need to apply for radio frequency?

No, this system uses a protection loop line for signal transmission and does not require radio frequency application or antenna wires.

Q:What are the available frequency channels?

The system offers three frequency channels: 250KHz, 741KHz, or 800KHz.

Q:What is the effective range of the system?

The effective range is more than 300 meters, provided the conductor loop resistance is less than 600 ohms.
