1. Overview

The PCB (Printed Circuit Board) is the "brain" of the Elebia evo2 hook. It controls all electronic functions, including motor operation, encoder signal processing, radio communication with remote controls, LED indicators (models with bumper with leds), and battery management.

A faulty PCB can cause a wide range of issues, from complete hook failure to intermittent operation, communication problems, or incorrect LED behavior.

Important: After replacing the PCB, you must:

1. Enter the hook serial number into the new PCB.
2. Re-link any remote controls (eMini, eMax, Einst).
3. Calibrate the encoder.

The hook will not function correctly without completing all these steps.

2. Symptoms That Suggest PCB Replacement is Needed

• The hook does not beep when the battery is inserted (no power reaching the board).
• The hook does not respond to the manual button or any remote control.
• The hook has water damage or visible corrosion on the PCB.
• The hook behaves erratically (random opening/closing, incorrect LEDs) after ruling out other components.
• The hook cannot be reset or does not respond to reset attempts.
• After replacing the motor, clutch, and encoder, the hook still does not function correctly.

Before concluding that the PCB is faulty: Verify that:

• The battery is fully charged and working (test with another hook).
• The battery contacts are clean and not bent.
• Check the voltage on the power wires.
• The motor and encoder cables are properly connected.

3. Required Tools

• L-shaped Hex Keys (Allen keys) set: For removing the hook's covers.
• Soldering iron and solder (if applicable): For models where cables are soldered rather than connected via plugs.
• New PCB unit (order correct spare part for your hook model and region).

4. PCB Location on evo2

On the evo2 model, the PCB is located behind the front cover of the hook. It is protected by an additional plastic cover.

5. Replacement Procedure

Step 1: Disconnect power
Remove the battery from the hook.

Step 2: Remove the front cover
Using the appropriate hex keys, remove the screws securing the front cover of the hook. Set the cover aside.

Step 3: Remove the PCB protective cover
Remove the plastic cover that protects the PCB. This cover is held by one screw.

Step 4: Document cable connections
Before disconnecting anything, take a clear photo or make a diagram of all cable connections to the PCB. This will be essential for correct reassembly.

The main connections on an evo2 PCB include:

Step 5: Disconnect all cables
Carefully disconnect all cables from the old PCB.

• For connectors: Gently remove any hot glue securing the connectors before disconnecting.
• For soldered connections: Note the exact connection of each wire before desoldering.

Step 6: Remove the old PCB
Remove the screws securing the PCB to the hook frame. Carefully lift the old PCB out of the hook.

Step 7: Install the new PCB
Place the new PCB in the correct position and secure it with the screws.

Step 8: Reconnect all cables
Following your photos or diagram, reconnect all cables to the new PCB.

• Ensure each connector fits into place securely.
• For soldered connections, solder each wire to the correct wire.
• Apply hot glue to connectors if the original installation had it (for vibration resistance).

Step 9: Reinstall the protective covers
Reinstall the plastic PCB protective cover and the front cover. Secure all screws.

6. Post-Replacement Configuration (Mandatory)

After installing a new PCB, you must complete the following steps in order. The hook will not work correctly if any step is skipped.

Step 1: Enter the hook serial number

Once the PCB has been installed, it is necessary to proceed with its initialization. In the following article, you can find the steps to perform this procedure [here].

Step 2: Configure radio frequency (if needed)

By default, new PCBs come with European frequency (F-8). Change it to match your region if necessary.

Step 3: Re-link remote controls

After entering the serial number, you must re-link remote controls (eMini, Einst) to the new PCB.

Step 4: Calibrate the encoder

After linking the remote controls, you must calibrate the hook.

Calibration procedure for evo2:

1. Hang the hook vertically in the closed position.
2. Turn off any eMAX remote in the area.
3. Press and hold the manual button on the hook.
4. Insert the battery.
5. You will hear a series of fast beeps. Release the button.
6. Press the button again once (short press, do not hold).
7. The hook will open and close automatically.
8. Verify calibration: A properly calibrated hook emits two beeps at the end of each stroke (both opening and closing).

7. Verification Checklist

After completing all steps, verify the following:

• The hook beeps twice when the battery is inserted.
• The manual button opens and closes the hook completely.
• The eMini remote opens and closes the hook completely.
• The eMAX remote (if used) detects the hook and shows the correct status.
• The LEDs (if equipped) show the correct colors (green when open, blue when closed).
• The hook emits two beeps at the end of each opening and closing movement.

8. How to Order a Replacement PCB

To order a replacement PCB, please visit the spare parts portal. [here]

Provide the following information:

• Hook model (evo2 or evo2L)
• Hook serial number
• Your region 
• Part number: EVO2-1400 / EVO2-1400-ARIB

Important: PCBs are region-specific due to radio frequency regulations. Always specify the country where the hook will be used.

9. When to Escalate

If after replacing the PCB and completing all configuration steps the hook still does not function correctly, contact Elebia technical support for further assistance.
