STAI 1 series
Where there is only restricted installation space, the rail-mounted STAI 1 is used: For conditions such as restricted space at the sides, this is a good alternative to the classic shaft mounting option. The rails used withstand the tough conditions under which they operate. There are three lenghts to choose from, with hard-wearing roller chains up to a maximum of 4.5 metres, as well as all the installation materials required.
Rail-guided installation is a solution when there is not enough space for classic shaft mounting. The opener is mounted at the end of a robust rail in which a carriage moves over a roller chain. The sliding carriage is connected to the door. That gives the opener the power it needs for large, heavy doors.
Mains voltage variants 400 V | 230 V FU
We always have the right solution with our door openers. If you need to generate more power from 230 V mains voltage, we have a solution that includes a frequency converter.
Door opener 400 V, 3-phase: Silent, smooth, resilient. In a word: strong as a bear. This 3-phase 400 V motor is the right solution for large, heavy doors.
Door opener 230 V, single-phase with a frequency converter: Quiet and strong even without high voltage. This opener is more powerful than the available mains power would suggest. It’s the frequency converter that gives it that extra boost. It generates the strong 3-phase mains voltage where only 230 V is available. This gives the motor the power it needs for large, heavy doors. It runs at twice the speed but still uses the door-saving soft-start and soft-stop function. We offer it exclusively in combination with our external comfort control CS 310.
External control units
ttConvenient, safe and expandable: You can operate our door openers even more conveniently with our external control units. In addition, every system offers you the option of expanding it.
CS 310, the comfortable one: The CS 310 is our external comfort control unit, that leaves nothing to be desired. It offers four output relays for additional functions. Use this, for example, for signal lamps, traffic lights, electrical door locking or the end position alarm. Other elements can be supplied with 24 V or 230 V power. Accessories are connected directly to the control unit. A Multi-Bit radio antenna can be inserted directly into a slot in the CS 310 and plugged in without wiring.
CS 255 AC, the compact one: The CS 255 AC is our compact basic control unit in a mini-housing which has all the features needed for safe operation. With a deadman control unit as standard. This function can be expanded to press-and-release operation by installing safety components. An output relay for an additionally connectable function, such as a signal lamp, is included. External elements are powered with 24 V voltage from the CS 255 AC. Multi-Bit and bi·linked radio is possible with the CS 255 AC; the slot for the radio antenna is already included.
Expand as needed: Both control units can be expanded through MS-Bus modules, for example, for oncoming traffic regulation or draw-in protection.
Even more safety: Safety equipment, such as photocells or a closing edge safety device, can be connected via terminals.
Easy and comfortable: Easy, plug-in cable sets ensure comfortable installation.
Emergency operation of rail-guided, spring balanced doors
The emergency operation and release directly on the sliding carriage of the opener rail creates safety. The door is disconnected from the opener with a single click using a snare. That means the door can still be moved even if there is no power.
Length of use 60 % or 80 %
When choosing the right door opener, the load, or the length of use, is decisive in addition to the power. Here, we can provide you solutions with 400 V openers for average use doors or heavily frequented doors.
60 % duty cycle: Normal duty cycle for 400 V openers. Designed for doors with average opening frequency. This corresponds to a maximum of 20 door cycles per hour.
80 % duty cycle: Increased duty cycle for 400 V openers. Designed for doors with high opening frequency. This corresponds to a maximum of 30 doors cycles per hour.
One cycle corresponds to opening and closing the door one single time.
Digital limit switch
An absolute value encoder guarantees precise travel cut-out. The end position of the control unit is not only conveniently set using the digital limit switch, it also keeps it correct.
Silent, compact, smooth. Where there is an »S«, it’s silent inside. This single-phase 230 V motor door opener works particularly smoothly and silently because of its noise-optimised motor winding package.
