Robotiq PE10 Palletizing Solution - Fuse F3 Frequently Tripping – Recommended Corrective Action

In certain PE10 Palletizers, Fuse "F3" has been reported to tripping regularly. This intermittent issue can lead to temporary downtime and necessitates manual resetting of the fuse.

Probable Cause

Inspection revealed that Fuse F3 was installed flush against the power supply module. This proximity may cause increased heat transfer or mechanical stress, leading to the fuse tripping more frequently than expected.

Solution

  1. Create a Gap Between Fuse F3 and the Power Supply

    • Introduce a gap of 2–3 mm between Fuse F3 and the power supply module.

    • This small separation helps to reduce heat transfer and mechanical pressure on the fuse, thereby preventing the nuisance tripping.

  2. Verify/Replace the Fuse

    • Ensure that the appropriate electronic fuse is installed.

    • Confirm that the fuse rating matches the system’s requirements as specified in the PE10 Electrical Schematics documentation. This might involve checking whether the fuse’s nominal current (for example, 2 A or 3.2 A) is set correctly.

Additional Tips

  • Programming the Nominal Current:
    Many electronic fuses allow you to program the nominal current by pressing and holding a button on the unit. To change the nominal current:

    1. Press and hold the channel button for more than 2 seconds to enter programming mode.

    2. Observe the flashing pattern, which indicates the current setting (e.g., two flashes for 2 A).

    3. Press the button repeatedly to cycle through the available current settings.

    4. Press and hold the button again for more than 2 seconds to store the new setting.

  • Mounting Best Practices:

    • Ensure that all DIN rail components are installed with adequate spacing to minimize heat transfer.

    • Confirm that all wiring connections are secure to prevent loose terminations, which can lead to voltage drops or additional fuse tripping.
