Replacing four separate control modules with one integrated unit changes the layout of a remote-controlled mower. This guide explains the MERI dual-motor architecture, the demonstrated six-wire receiver connection and the checks needed to match the controller to a machine.
One integrated controller combines the two travel motor drives, conversion control and actuator control. The radio receiver remains external. Match the motor type, supply, feedback connections and receiver assignments before connecting the system. Both the 110A and 190A versions feature protective potting and IP56 protection.
Understand What the Integrated Unit Replaces
Separate modules
- Left travel motor driver
- Right travel motor driver
- Signal conversion controller
- Actuator controller
Integrated architecture
One unit combines all four control modules. The external receiver sends the matched commands to this integrated control system.
This brings travel and auxiliary control together while reducing the separate boxes and inter-module connections.
Potted Electronics & IP56 Protection for Field Work
Dust, moisture and contamination are everyday challenges around outdoor equipment. MERI’s potting and sealing protect the internal electronics and reduce contamination-related failure risk. Both 110A and 190A specifications are rated IP56.
Protected circuits
Potting adds a protective barrier around sensitive electronics.
Cleaner wiring
Fewer inter-module connections simplify the control layout.
Centralized functions
Travel, actuator, engine start/stop and lighting interfaces share one control architecture.
Prepare the Hardware Before Wiring
- Identify the specification. The110A version is listed at 1600W and 230×112×72mm; the 190A version at 2400W and 260×140×70mm. Compare the model-specific technical sheet.
- Record both motors. Confirm voltage, rated power, square-wave BLDC motor type and feedback connections.
- Identify the receiver. Photograph its label, outputs and existing channel assignments.
- Record auxiliary functions. Identify the actuator, engine enable/start-stop and lighting circuits.
- Isolate power. Follow the machine’s delivered instructions before handling wiring or connectors.
Both technical sheets list 24–72V DC compatibility. Use the actual delivered controller configuration for the machine; do not use wire colors or plug shape as the only identification.
Six-Wire Receiver Connection: Watch the Demonstration
The following positions describe the harness in the MERI demonstration. They are not a universal pinout for every receiver or controller.
| Harness position | Demonstrated function |
|---|---|
| 1 and 3 | Travel signals; shown connected to receiver channels 1 and 2. |
| 5 | Electric actuator control. |
| 6 | Engine start/stop. |
| 7 | Lighting. |
| 8 | Additional actuator signal; unused in this setup. |
Harness position and receiver channel are different identifiers. Check the connector orientation and wiring diagram for the actual controller/receiver pair before applying power.
Connection & Commissioning Checklist
Before power is applied
- Compare supply terminals and polarity against the correct diagram.
- Match each motor’s phase and feedback connections.
- Match receiver assignments to travel and auxiliary functions.
- Secure the harness away from heat, sharp edges and moving parts.
- Check mounting, connector engagement and the machine’s protective components.
Commission the complete system
- Use the commissioning procedure for the delivered controller and machine.
- Confirm left/right travel and direction in a controlled setup.
- Check actuator travel, engine start/stop and lighting functions.
- Verify emergency-stop and loss-of-signal behavior according to the approved system instructions.
- Stop and resolve unexpected motion or incorrect outputs before field work.
For other systems, use this as a preparation checklist alongside their specific wiring and commissioning instructions. It does not authorize bypassing safety functions or adapting unidentified electrical connections.
Choose the Right Controller Before Replacing Parts
If an existing machine has one failed board, first identify what that board controls. A main board replacement and a complete integrated-controller upgrade are different jobs. The receiver, retained drivers and actuator or hydraulic controls determine the correct replacement scope.
Use the full-system controller replacement checklist, then compare the 110A and 190A integrated controller specifications.
Read the Swiss main-board parts enquiry case for an example of tracing the affected function before ordering.
Installation Questions
Does integration include the radio receiver?
No. The receiver remains external; the controller integrates motor drives, conversion control and actuator control.
Can I connect wires by color alone?
Use the verified connector orientation, function and pin assignments. Colors are not a universal wiring standard.
Why are travel positions 1 and 3 connected to channels 1 and 2?
The first numbers identify positions in the demonstrated harness; the latter identify receiver channels. They refer to different parts of the connection.
Is position 8 always unused?
It is unused in this demonstrated setup. Another matched configuration may use the additional actuator function.
Which PDF should I download?
Use the 110A or190A formal TDS for the unit under consideration. The product page and Support Downloads share the same formal files.
Get the Controller & Wiring Matched Together
Send the motor labels, receiver model, controller photos and machine wiring layout. MERI can review the replacement scope before quoting.
