Are you interested in the technical details of our sectional door operators? Obtain detailed information on the features of the operators for spring-balanced sectional doors (STA 1, STAC 1, STA 1 FC/I, STAI 1) and springless sectional doors (MDF) here. General information is available on our overview page for sectional door operators.
Our operators for sectional doors offer the right solution for every situation – both with and without heavy-duty power supply. Depending on your individual requirements, you can choose between various options.
Door/Gate Operator 400 V, 3-Phase
This operator can be described in a single word: mighty. This makes a 3-phase 400 V motor the ideal solution for big, heavy doors and gates – springless and spring-balanced.
Door/Gate Operator 230 V, 1-Phase for STA 1 and STAC 1
No heavy-duty power supply available? No problem, with a single-phase 230 V motor, we also offer variants for our STAW 1 and STAWC 1 operators that can be used without a heavy-duty power supply. This operator is the best solution for smaller door surfaces or gates with a low opening frequency, i.e. a small number of door cycles.
Door/Gate operator 230 V, 1-Phase with Frequency Converter (FC) for STA 1 FC/I and STAI 1
These operators variants from the STA 1 FC/I and STAI 1 FC/I series are more powerful than the existing power supply would make them appear. The secret here is the frequency converter. It generates powerful 3-phase voltage and current where only 230 V is available. This makes the motor powerful enough for large, heavy doors and gates. It runs at almost double the speed, yet still features soft start and soft stop functions, which are gentle on the door or gate. We offer it exclusively in combination with our external CS 320 comfortable control unit.
We offer you systems with two different shafts. Both our cost-effective universal solution, the standard hollow shaft with a diameter of 25.4 mm, and on request a special hollow shaft, for example with a diameter of 30.0 mm, 31.75 mm, 35.0 mm, are high-quality solutions.
Our standard 25.4 mm hollow shaft is the compact and cost-effective universal solution for most doors and gates. The operator can simply be fitted onto the spring shaft of the gate or door. The hollow gear shaft of the operator is made of steel.
When choosing the right door operator, decisive factors include not only its strength, but also what is called the opening cycle: How often will the door or gate be opened and closed again each hour?
Hence, we offer you solutions for doors and gates with average usage, as well as for those with a high frequency of use with 400 V operators.
Emergency operation mechanisms provide safety: They ensure that a gate or door can be opened and closed even during a power outage .
Emergency Operation of Spring-Balanced Doors and Gates (KE, E/KE)
KE (emergency hand chains) provide standard emergency operation for openers with a 25.4 mm standard hollow shaft. The emergency hand chain enables convenient operation of the door/gate from the ground.
E/KE (emergency hand chains with maintenance release) are the most convenient and best solution. The E/KE is the standard emergency operation option for openers with a splined hollow shaft. The emergency hand chain enables convenient operation of the door/gate from the ground. At the same time, the maintenance release enables fast and inexpensive servicing because there is no need for time-consuming disassembly of the motor or detachment of the opener shaft from the door/gate shaft.
Emergency Operation of Springless Doors and Roller Shutters (KE, KU)
KE (emergency hand chain): The emergency hand chain can be ordered for springless doors and roller shutters . It allows for convenient operation of the door/gate from the ground in the event of a power failure.
KU (emergency hand crank): The emergency hand crank provides standard emergency operation for springless doors and roller shutters. The crank is attached directly to the opener to save space. If desired, the operator can be retrofitted for emergency operation from crank to chain.
Emergency Operation of Rail-Guided, Spring-Balanced Doors and Gates
The emergency operation and unlocking takes place directly on the guide carriage of the operator rail, ensuring safety. The door or gate is separated from the drive with a single action via a pull loop. This allows the gate or door to be moved, even when there is no power.
Are you looking for a operator that is particularly silent? Is there limited space for installation? Or is an integrated safety catch important? We have suitable solutions for your specific requirements.
The absolute encoder guarantees a precise limit stop. With the digital limit switch, the end position can not only be conveniently set on the control unit – it also ensures that it is always adhered to precisely.
For STAWS 1: Quiet, compact, smooth-running. The “S” stands for “silent”. Thanks to its noise-optimized motor winding package, this operator with single-phase 230 V motor operates particularly smoothly and quietly.
The rail-guided mounting of the STAI 1 is the solution when there is insufficient space for classic shaft mounting. The operator is mounted at the end of a robust rail, on which it drives a carriage via a roller chain. This carriage is connected to the gate or door. This makes the operator powerful enough for big, heavy doors and gates..
The safety catch of the MDF series equates to added safety. In an emergency, it prevents the door or gate from falling down. It is maintenance-free and independent of position and speed: No matter the position in which the motor is mounted, the safety catch works reliably. It does this regardless of the output speed.
Depending on the operator, we offer you different control units and options.
The CS 320 is our external comfortable control unit that leaves nothing to be desired. It offers numerous useful functions and can be used with all types of operators. This makes the CS 320 a universal control unit for industrial doors and gates.
Our CS 255 AC Basic Control Unit
The CS 255 AC is our compact basic control unit in a mini housing or integrated in the operator, and which includes all features for safe operation. With dead man’s control as standard.
To our Industrial Door Control Units
Expand as required
Both control units can be expanded via MS bus modules, e.g. for two-way traffic control or with a safety device that prevents objects getting pulled in.
Even more safety
Safety features such as a light barrier or a closing edge safety device can be easily connected using the provided terminals.
Ease of use and convenience
Easy plug-in cable sets ensure convenient installation.
