Wiring Diagram and Installation Support
The final wiring depends on receiver voltage, machine control circuit and required function mapping. Send us the equipment wiring diagram, control-box photo or original receiver label before installation. HZBOY can confirm terminal assignments, interlocking logic and the correct receiver version. The model-specific wiring diagram will be added here when the final drawing is available.
How to Confirm the Correct Configuration
- Confirm the control-circuit voltage, not only the machine main-power voltage.
- List the four required functions and button labels.
- Specify which movements must be electrically interlocked.
- Provide the destination country so the frequency option can be checked.

Frequently Asked Questions
Can the four button functions be customized?
Yes. Button symbols, output assignments and interlocking logic can be configured according to the machine requirements.
How do I choose the receiver voltage?
Check the equipment control-circuit voltage or original receiver label. If uncertain, send a wiring diagram or control-box photo for confirmation.
Can I order a replacement transmitter?
Yes. Please provide the existing model, frequency, receiver label and pairing information so compatibility can be checked first.
Request a Configuration Check
Send the model, quantity, receiver voltage, four required functions, destination country and equipment type. For replacement projects, include clear photos of the existing transmitter, receiver label and wiring diagram.
