Maintenance and Disposal

Guidelines for routine maintenance and proper disposal of the SUMO gear motor.

The Nice SUMO is an electromechanical gearmotor designed for automating the movement of sectional doors and two-wing sliding doors. It is available in two models: SU2000 and SU2010.

Function Description:

The SUMO gearmotor powers the direct current motor with an encoder, and its A924 control unit offers precise torque and gear motor speed adjustment, exact position detection, gradual departure and closing, and obstacle detection. It also features a maintenance LED that records the maneuvers performed by the gear motor during its working life. The cable outlet shaft is designed for easy connection to the spring holder shaft of most sectional doors available on the market. A key feature is the release device, which disengages the motor from the gearmotor and can be activated from the ground.

Usage Features:

The SUMO system is designed for automating well-balanced doors that can be opened by hand, requiring a force of less than 300N (30kg) and capable of stopping in any position without rising or lowering after being blocked. It is not suitable for installation in explosive atmospheres.

Before installation, preliminary checks are crucial:

Ensure the door does not stick when opening or closing.
Verify that the door can be moved with a force of less than 300N (30kg).
Confirm the door is well-balanced and remains motionless when stopped in any position.
Check that the door moves silently, smoothly, and without skidding.
Ensure the fixing area is compatible with the gearmotor's size.

The SUMO can be installed in several configurations:

Standard procedure: Involves mounting the gearmotor directly onto the spring holder shaft.
Vertical chain installation: Required for special applications, such as when the gearmotor size makes standard installation impossible, the release maneuver cannot be performed safely, or increased transmitted torque is needed. Nice offers accessories like CRA1 (shaft with pinion Z=18), CRA6 (gear Z=36), CRA7 (gear Z=18), CRA8 (wall-fixing bracket), and CRA2, CRA3, CRA4 (sufficient chain) for this setup. The chain must be at least 2.4m from the ground and positioned to prevent access by people's arms; if not possible, a safety guard is required. The shaft to which the gear is splined must be sufficiently rigid (not bending more than 2mm under a 4000N load).
Horizontal chain installation: Used for two-leaf sliding doors, with accessories like CRA1, CRA5 (chain tightening device), CRA8, and CRA2, CRA3, CRA4.

Electrical Connections:

The power unit must not be powered during electrical connections. The power cable (3x2.5mm²) connects to terminals 1-2 (ensuring the earth wire is insulated), and the encoder cable (2x0.75mm²) connects to terminals 3-4. For cables longer than 10m, a cross-section of 4mm² is recommended.

Manual Maneuver or Release:

For models SU2000 and SU2010, the door can be manually operated by pulling the knob downwards to position 1 and then moving the door by hand. The release device should only be activated when the door is stopped.

Testing:

Testing must be performed by qualified and expert staff. The procedure includes:

Closing the door.
Disconnecting power from the control unit.
Releasing the gearmotor.
Checking the slide way for cleanliness and debris.
Manually opening the door with a force less than 300N.
Verifying the door does not stick and remains motionless when stopped.
Checking safety systems, mechanical stops, and screw connections.
Ensuring the chain (if present) is taut and slides well, lubricating if necessary.
Blocking the gearmotor and powering the control unit.
Adjusting the actuator force via the electronic control unit.
Measuring impact force according to EN12445 and EN1245353 standards.

Maintenance Features:

The A924 control unit includes a maintenance LED that signals when routine maintenance is required. Regular maintenance is essential for longer life and safe system operation. Maintenance should only be performed by qualified staff and involves repeating the test procedure. Nice recommends a visit every six months for normal residential use, though this period can vary.

Disposal:

The SUMO comprises various materials that must be disposed of according to local laws. There are no particular dangers during demolition. If waste sorting is required, components should be grouped by material type (electrical, aluminum, plastic, etc.).

Important Information for Users:

Safety: The automated system offers a high level of safety with detection systems that stop movement in the presence of people or objects. Children should not play near the system, and remote controls should be kept out of their reach.
Faults: In case of abnormal behavior, disconnect the system, perform manual release, and contact a fitter. Do not attempt repairs yourself.
Remote Control Batteries: If the radio control unit malfunctions, check the batteries. A faint or non-lighting transmission OK LED indicates low batteries.
System Modifications: Do not modify the system or its programming/adjustment parameters.
Documentation: Final testing, routine maintenance, and repairs must be documented by the fitter and kept by the owner.
Power Failure: In case of power failure, the system can be used manually by performing the release operation.
