Sommer swing gate operators – installation and commissioning for single and double-leaf gates
Sommer swing gate operators are among the most reliable systems on the market. Whether twist 200 EL, twist XL, or twist UG, installation follows a clear pattern. There are differences, especially in installation dimensions and forces, but the basic principles are identical. In this guide, we explain installation and commissioning step by step, provide practical tips, and highlight typical sources of error – with practical expertise.
1) Why Sommer swing gate operators?
Sommer is a leading manufacturer of gate operators. Swing gate operators from the twist series are robust, durable, and suitable for a wide range of applications. Advantages at a glance:
- Suitable for single and double-leaf gates.
- Convenience through operation via hand-held transmitter, code keypad or smart home .
- Safety through obstacle detection, light barriers and automatic locking.
- CE-approved and compliant with European standards.
2) Preparation: Gate system & security
Before assembly:
- Gate test: Must run smoothly mechanically.
- Pillars: Check stability, observe installation dimensions.
- Tools: drill, spirit level, wrench, multimeter.
- Power: Prepare 230 V AC or 24 V DC depending on the model.
- Safety: Use only CE-approved components.
3) 24 V or 230 V – which drive is suitable?
| criterion | 24 V drive | 230 V drive |
|---|---|---|
| Security | Low voltage, safer | Mains voltage, professional installation required |
| Mission | Private, easier goals | Heavy gates, industry |
| Special features | Battery operation & solar possible | High continuous load capacity |
4) Installation 1-wing
Step by step:
- Install brackets: Align precisely on the pillar, drill holes according to the dimension plan.
- Attaching the motor arm: Mount the joint on the wing, ensuring freedom of movement.
- End stops: Set mechanical stoppers to prevent the motor from overrunning.
- Check emergency release: insert key, make gate moveable by hand.
5) Installation 2-wing
For double-leaf gates:
- Install two motors (one for each wing).
- Configure control to master/slave.
- Set synchronous operation: Wings must close at the same time.
- Activate partial opening for pedestrian passage.
6) Electrical connection & accessories - to be done by a specialist - do not work under voltage
- Motor connections: Correctly polarize cables, check direction of rotation.
- Control: Programming via DIP switch or display.
- Safety: Connect light barriers , warning lights, flashing lights.
- Operation: teach-in hand-held transmitter, code keypad , smart home .
7) Initial commissioning & learning run
- Turn on the power.
- Control starts learning run → end positions are taught.
- Check safety shutdown: Gate must stop when encountering an obstacle.
- Test synchronous operation (with 2 leaves).
8) Checklist: Before the first run
- Are all screws tightened?
- Cables laid properly?
- Light barriers tested?
- End positions programmed/set
- Emergency release works?
9) Special assembly situations
- Narrow pillars: special brackets required.
- Large wings: Use reinforced motors (e.g. twist XL).
- Slope: Adjust end positions and motor position.
10) Troubleshooting & Tips
| symptom | Caused | Solution |
|---|---|---|
| Gate does not open | No power supply | Check fuses |
| Gate remains half-stopped | End positions incorrect | Reprogram |
| Motor is running, gate does not move | Fastening loose | Tighten screws |
11) Safety, CE & DGUV
- CE marking: Mandatory for drives and accessories.
- DGUV regulations: Commercial doors must be inspected annually.
- Operator obligation: maintenance & documentation.
12) Practical examples from the Rhine-Main area
Mainz: Single-leaf courtyard gate with twist 200 EL – integration into smart home.
Wiesbaden: Double-leaf gate with twist XL – synchronous operation, code keypad.
Frankfurt: Underfloor swing gate (twist UG) – invisible installation, CE-compliant.
13) FAQ – frequently asked questions
Can I install Sommer swing gate openers myself?
Mechanically yes, electrical connection only with specialist knowledge.
What is the difference between 24 V and 230 V?
24 V: safer, battery-operated. 230 V: more powerful, for larger gates.
Do mechanical stops need to be set?
Yes, to prevent overruns.
How do I program the remote control?
Teach in via control, assign button.
How does partial opening work?
Control allows only one wing to open – ideal for pedestrians.
Which security is mandatory?
Light barriers, emergency release, obstacle detection.
Does a specialist company have to carry out the inspection?
Private not necessarily, commercial yes (DGUV).
How often does maintenance need to be done?
Private: every 1–2 years. Commercial: mandatory annually.
What to do in case of a power outage?
Use emergency release.
Where can I get spare parts?

14) Conclusion – reliable & durable
Sommer swing gate openers offer a high level of convenience and security. Installation is similar for all models, but there are differences in power and dimensions. Important: Mechanical work can be performed by experienced do-it-yourselfers themselves, while electrical installation should only be carried out by a specialist. With products from Tormeister24 and service from Schweighöfer Tortechnik, you're in the best hands.
