Precautions for Pump Truck Remote Control Operation

Operating Tips for Concrete Pump Truck Remote Control System

1. When controlling the boom movement, push or pull the corresponding joysticks with steady, even force. Avoid pushing or pulling too quickly. The boom's unfolding and retracting speeds are controlled by the system's internal current (which is pre-set based on normal control parameters). Once the joystick is moved to its limit, the output current has already reached its maximum; forcing it further will have no effect. Forcibly pushing or pulling the joystick can easily cause misalignment, preventing it from returning to neutral and leading to system malfunction.

2. When the indicator light on the transmitter changes from green to red, it indicates low battery power, and the battery needs charging. When fully charged under normal working conditions, the battery can last for eight to ten hours. It is best to use the battery until the red light appears before recharging.

3. Both the receiver and transmitter have an ingress protection rating of IP65. During operation, as the transmitter is manually handled, try to avoid exposing it to excessive rain, especially during the rainy season. If it gets wet, dry it appropriately before storing it.

4. It is best not to frequently remove the antenna from the receiver. Especially during the rainy season, because the receiver is located externally. If the antenna is removed while the pump truck is parked, the antenna jack on the receiver is left exposed. When it rains, water can accumulate in this jack. If this water is not dried before subsequent use, it can severely affect the signal reception.

5. When operating on high-rise buildings, if the receiver is installed inside the cab, you can replace the antenna with a magnetic mount antenna to lead it out of the cab and place it on top of the vehicle's cab for better signal reception. If the receiver is installed on the right (or left) side of the vehicle body, try to position the vehicle during setup so that this side faces the working face, or replace the receiver antenna with a magnetic mount antenna placed on the roof.

6. If co-channel interference occurs during operation (identified when the normally off red indicator light on the receiver starts flashing during normal operation and the boom does not respond to commands), indicating interference in the work area:

• For the FST-719 remote control: Turn the system key switch off and on once. The system will automatically jump to the next frequency point to avoid interference. If interference persists after one auto-hop, try switching it off and on once more.

7. If the work area is subject to fixed frequency band interference (e.g., near high-power radio transmitters like TV towers, broadcast stations, or military interference stations), the remote control system may be unable to function, regardless of frequency changes. In this situation, wired control can be used. (The wired control for HBC remote systems uses a bus control method and can resolve system failure caused by wireless interference). Connect the transmitter to the receiver using the provided 30-meter control cable as instructed. Note: The two connectors are different; ensure they are fully inserted and screwed tight after connection. During operation, be careful not to pull the control cable too tightly and protect it from being crushed by construction equipment or materials.
