Drive & Transmission
The motor and transmission create the movement. Review them with the moving door weight, travel and opening arrangement.
Sliding Door Systems
Automatic Sliding Door Opener
Select the opener around the door it will move. Review door-leaf weight, mounting space and operating requirements with SEPPES for a complete sliding-door project or replacement support for an earlier order.

What Does the Opener Include?
An automatic sliding door opener moves and controls the sliding leaves through a coordinated drive and mechanical assembly. Check the equipment included in the proposal, from the motor and controller to the track hardware and external devices.
Controller & Power
The controller coordinates opening requests and the configured closing response. Confirm the electrical supply and connected devices.
Track & Hangers
The track and hanger arrangement supports guided travel. Door connections, mounting support and service access belong in the same review.
Door leaves, frames, activation and presence sensors, locks and access devices require separate scope confirmation. An opener description alone does not define a complete entrance.

What Determines the Right Configuration?
Use the conditions below to prepare an opener selection discussion. If you are comparing an automatic sliding glass door opener for a new entrance, begin with the moving leaves and available installation space.
These are inputs for configuration review. Final capacities, dimensions, settings and interfaces are confirmed for the selected arrangement.
| Selection Input | What to Provide | What to Confirm |
|---|---|---|
| Door construction & weight | Dimensions and weight of each moving leaf; glass, frame and attachment details. | The drive, hangers and connections for that moving load. State per-leaf weight separately from total weight. |
| Opening arrangement & travel | Single-sliding or bi-parting layout, clear opening and available side space; identify telescopic requirements separately. | Panel travel, rail arrangement and the mechanical configuration required for the entrance. |
| Header & mounting space | Mounting surface, space above the opening, adjacent ceiling and photographs of the fixing area. | How the assembly is supported and whether the cover and components remain accessible for service. |
| Use & movement settings | Building use, busy periods and desired opening, closing and hold-open behavior. | The configuration and settings appropriate to the moving door, pedestrian use and sensing arrangement. |
| Power & installation environment | Available site power, cable routes and whether the header is exposed to weather or moisture. | Electrical preparation and the suitability of the selected equipment for those conditions. |
| Sensing & access requirements | Opening triggers, monitored areas, access equipment and the response required during restricted use. | Device functions, controller interfaces and who supplies and connects each item. |
Scroll across the table to read each selection input and its confirmation points.

Installation & Replacement
Reviewing an Existing Sliding Door
Before changing the opener, review the entrance around it. The existing door leaves, track, mounting support and control equipment affect what can be retained and what needs further attention.
- 01
Identify the earlier supply
Existing customers can send their order or project reference, available equipment labels and photographs of the door and relevant parts.
- 02
Describe what has changed
Explain the observed problem and any changes to the door leaves, hardware or connected controls. Include when the issue occurs.
- 03
Review the complete connection
Confirm mechanical fit, electrical interfaces, matching accessories and installation responsibilities before selecting a replacement.
A similar-looking opener or connector does not establish a replacement match. For an entrance conversion, the review may lead to a broader door and system scope.
Define the Required Response
Coordinate Activation, Safety and Access
Specify what the entrance should do when someone approaches, remains in the passage or requests restricted access. These requirements guide device selection and control coordination.
Opening Requests
Describe how users should request entry: approach detection, a push button or an access-control device. Identify which equipment supplies that request.
Presence & Closing
Identify the areas that need monitoring during passage and closing. Review device positions and the controller response with the door layout.
Access & Operating Modes
Explain normal and restricted access, locking requirements and special operating needs. Confirm the interface and response for the selected configuration.
Emergency Opening and Manual Release can be reviewed for the applicable configuration. Their activation logic, required accessories and power-loss response are confirmed with the project.
Understand Activation and Presence DetectionFor controller interfaces, connected equipment and maintenance coordination, review the Automatic Door Operator guide.
For sensing positions, approach routes and replacement information, review Sliding Door Sensor Requirements.
Working with SEPPES
Supply Scope and Project Support
Our main focus is complete door supply. Operator systems, components and accessories are generally supplied to existing customers as replacement, spare or repair parts. Large-volume standalone requirements, such as hundreds or thousands of sets, can be discussed separately.
Complete Door Projects
Start with the entrance and door construction. We review the opener as part of the coordinated complete-door supply.
Existing-Customer Support
Connect replacement, spare-part and repair requests to the original SEPPES order so the earlier configuration can be reviewed.
Large Standalone Requirements
Provide quantity, intended door construction, mounting conditions and requested items for a separate supply discussion.
Before you order, we’ll help you confirm the quantities, check that the equipment suits your door and clarify what’s included. We also provide remote installation guidance and troubleshooting to support your team on site.

Questions Before You Specify an Opener
Practical starting points for a sliding-door project, an existing entrance or replacement support.
Can you review an opener if I do not know the door weight?
Yes. Start with the dimensions of each moving leaf, glass specification and frame construction. We can identify the missing information with you. The final moving weight and hardware arrangement still need confirmation before configuration is agreed.
Can an opener be fitted to my existing sliding glass door?
An existing entrance needs a review of its door condition, mounting support, track, hangers, connections and control equipment. Share the available information before assuming the opener can be fitted. For an earlier SEPPES order, include the order reference so replacement requirements can be checked against the supplied configuration.
Does an automatic sliding door opener include sensors and the door leaves?
The name alone does not establish what is included. Confirm the drive, controller, mechanical hardware, sensing equipment and accessories in the itemized scope. Door leaves, frames and surrounding site work need their own scope confirmation.
How are opening and closing settings selected?
Opening, closing and hold-open requirements are reviewed together with door weight, travel, use and sensing. An automatic sliding door opener and closer should be specified around that combined behavior; available settings are confirmed for the chosen configuration.
Can the opener work with an existing access-control system?
Integration can be reviewed once the access equipment, signal requirements, intended door response and responsibilities are known. Share device information and any available connection records. A reader brand or connector appearance alone does not confirm compatibility.
