Welcome to the EVO2 Wiring Guide! This article will help you understand the wiring connections for the EVO2, ensuring a smooth reconnection process.
1. EVO2 Motor Cable Identification
The EVO2 features six distinct connections to the PCB (Printed Circuit Board), each serving a specific function. Here’s a breakdown of the connections:
- Motor Power (Red + Black): This connection supplies power to the motor and is polarity sensitive. Ensure that the red wire connects to the red wire and the black wire to the black wire on the PCB. Reversing these wires will cause the motor to run in the opposite direction, which can lead to operational issues.
- Encoder (4-wires: Brown, White, Green, Yellow): This cables provides position feedback from the hook to the PCB. Each wire must be correctly matched and soldered to ensure accurate communication.
- Power Input (Blue + Red): These wires come from the battery housing and supply main power to the hook. An additional red wire is available for powering bumper LEDs if your model is equipped with them.
- Autoclose Sensor (Violet - 2 wires): This connection is for the magnet sensor that enables the autoclose function, ensuring the hook operates automatically under certain conditions. The magnet sensor for autoclose is an option; not all EVO2 units have it incorporated.
-Load cell (if equipped): This connection includes four wires (black, white, green, red) that link to a dedicated PCB connected to the hook PCB pins, providing weight measurement capabilities.
- Bumper with LEDs (if equipped): This connection consists of three wires (Green, Red, White) that connect to the side PCB pins via a dedicated connector, allowing for visual feedback through LEDs.
2. Connection diagram (textual description)
When wiring, it is crucial to maintain correct polarity.
Motor polarity:
-Connect the red wire to the Positive (+) terminal on the PCB.
-Connect the black wire to the Negative (-) terminal on the PCB.
Encoder and autoclose wiring:
-The motor, encoder, and autoclose wires are soldered directly to the corresponding wires on the PCB.
Load cell (if equipped):
-The load cell uses a dedicated PCB that connects to the hook PCB pins. the wires from the LC must be conected to the deicated pcb wires. (green, white, red, black)
Bumper LEDs (if equipped):
-The bumper LEDs use three wires (green, red, white) that go to a pin connector on the side of the PCB.
Power input:
-The blue and red wires from the battery are pre-connected to the PCB. If you need to power bumper LEDs, use the additional red wire provided.
3. Common Reconnection Errors and Consequences
Be mindful of these common errors during reconnection:
- Motor Red/Black Reversed: If these wires are reversed, the motor will run backward, causing the hook to open when it should close.
- Encoder Connection with Crossed Wires: Crossed wires can lead to calibration failures, preventing the hook from detecting its position accurately.
- Loose Encoder Connection: A loose connection may result in intermittent feedback, erratic movement, and calibration errors, impacting overall functionality.
4. Post-Connection Verification
After reconnecting the wiring, follow these verification steps:
1. Power on the hook: Listen for a series of short beeps, indicating successful initialization.
2. Run a calibration test: Confirm that the encoder feedback is correct. Refer to the Encoder Calibration article for detailed instructions.
3. Test full opening: Ensure the hook opens completely and stops as expected.
4. Test full closing: Verify that the hook closes completely.
If calibration fails or the hook behaves unexpectedly, please recheck all connections before proceeding.
