LOCK BEWEGT // LOCK MOVES 4 Ventilation tYPeS CHAPTER 01 – APPLICATIONS 2024 | 11 With Open-Roof systems, the roof can be opened almost completely to assure maximum ventilation. With our versatile selection of options for drive units and rack & pinion units, we are able to provide a solution to all Open-Roof variants. The mechanism can be an continous system (Types A + C) or a push-rod system (Type B). The distinguishing features of the three most commonly used type of Open-Roof ventilation system (Types A – C) are itemized below: Example of Open-Roof ventilation with Type A Type B Type C Open-Roof ventilation – Type A as continous system > Drive provided by a ventilation shaft centrally arranged under primary roof ridge. > Both sides of roof are moved simultaneously by one drive unit. > EWA power drives are used with 1–9 rpm. > In conjunction with the ZSG, AZD and EZD ranges of rack & pinion units, optimum closing times can be achieved. Open-Roof ventilation – Type B as push-rod system > Drive delivered by a push-rod system arranged on the rail mountings (see fig. on p. 18). > Each side of the roof is moved by its own drive unit. > The drive units employed are our high-speed EWA power drives, our tried and tested SpeedLogic or our TurboLogic systems. > In conjunction with the LZG / UBL ranges of rack & pinion units, optimum closing speeds can be achieved. Open-Roof ventilation – Type C as continous system > Arrangement of full-length ventilation flaps, same principle as on wide-span greenhouses. > The EWA power drive operating at 1–9 rpm is used here. In conjunction with our ZSG, AZD and EZD ranges of rack & pinion units, you obtain an optimum ventilation system. > With our reversing gear units, several ventilation flaps can also be grouped together to form a system.

CHAPTER 01 – APPLICATIONS RAIL VENTILATION 19 2024 | 11 General notes The following tables contain a sub-set of the roof systems available on the market. If you are unable on our tables to find the ventilation flaps or system dimensions you are planning to use in your project, we will be pleased to help you work out which types of LZG and EWA you require for an optimum drive system configuration. In our applications table, you can establish whether your project needs our LZG 20 with 5500 N or 10000 N, or even the LZG 24 with 13000 N and 16000 N. The torque required for the LZG is based on the linear load rating of the rack. Loadings applied by push bars are not taken into account here, and must be dissipated by the rail mounting on the building structure. The figures in these tables are non-binding. STANDARDS The table calculations are based on the German greenhouse standard DIN EN 13031-1 : 2003-09 greenhouse dimensions and construction - part 1: Culture greenhouses. This was based on the German edition EN 13031 – 1 : 2001. BASICS These tables can be used for projects involving the following dimensions: > Greenhouse widths (flap width) of 3.20 to 4.80 m. > The roof angle a is 22°– 25°. > The glass thickness is 4 mm (10 kg/m2). > The ‘gutter height‘ up to top edge of rail mounting (Tr) is 150 –180 mm. > The rack height (Hzd) may be 11–60 mm. > Calculation of the required stroke H presupposes that the opening angle of the window flaps is twice as large as the angle of roof inclination. > An LZG needs approx. 70 Nm of input torque at a load of 10000 N. INSECT PROTECTION for applications with insect protection, the details for ventilation flaps reduce due to their increased weight. With insect protection weighing 1800 g per linear metre, the value for the flaps must be reduced as follows: > With panel width of 3.20 m – 25 % > for all other panel widths – 20 % Note: > We are always delighted to advise you on configuration questions.

LOCK BEWEGT // LOCK MOVES 6 EWA CHAPTER 03 – POWER DRIVES 2024 | 11 Everything you always wanted to know about the drives of the EWA 5 and 1 series! 1. Self-locking: In all cases, a distinction is made with self-locking between static and dynamic self-locking. Static self-locking only works when stationary and can be cancelled by shaking or by vibration. This is why our self-locking drive units always have dynamic self-locking (also called autobraking). This occurs whenever an operating gear unit comes to a complete stop automatically, for example after the motor has been switched off. Like all self-locking gear units, our gear units cannot be operated in continuous basis. 2. Load details and service life: Our nominal load details are minimum figures, not maximum figures, unlike the practice of many other manufacturers. That means that if we quote a torque rating of ‚250 Nm‘, that means that the drive unit is capable of delivering this torque rating throughout its entire service life. This explains why our drive units are renowned for having high reserves of power. On our in-house test benches, we test our units for 1000 operating hours at the nominal load quoted in the catalogue, over the specified engagement period. The drive units are designed for endurance loads depending on utilization level (actual torque levels applied), application, peak loads and engagement cycles. 3. Electric motors: We do not use standard motors. Instead, we only use motors with optimized characteristics curves, and we optimize these for each version and for every variant. They are designed in such a way that voltage fluctuations of approx. +/- 5 % can be contended with, even in the 60-Hz range.
CHAPTER 03 – POWER DRIVES EWA 7 2024 | 11 4. Single-phase motors: Single-phase motors are always wired by ourselves before they leave the factory, and are supplied with a long connection cable. That means that the electric motor is switched off directly by the limit switch. This greatly simplifies assembly and is less expensive, because there is no need for a reversible contactor control system. A test run can be conducted on location using manual push-button TST 10. Having said that, single-phase motors must not be over-dimensioned. If they are operated at levels well below their nominal load rating, they are prone to heating up more, and this shortens their engagement period. The internal winding protection contact can be routed externally. 5. Special voltages: For 60 Hz we have always used special motors. We also always guarantee that the nominal load rating quoted is consistently achievable. This also applies to the other special voltage ratings. All special motors are optimized and tested before they are used on the test bench. 6. 24 V DC motors: Power drives EWA 10 and EWA 12 can be supplied with 24 V DC motors. A typical feature of DC motors is that current intake rise sharply as torque levels rise. 7. Smoke & heat extraction systems: Natural ventilation systems are often combined with smoke & heat extraction systems. With building-specific special constructions, no usability verification can be provided in accordance with DIN 12101-2. Here, it is possible to apply for consent in individual cases from the construction authorities. Our drive units have been inspected by the Fraunhofer Institut in respect of ‚usability‘ as defined in DIN 18232. Request the Fraunhofer certificate when needed. 8. A60 option: This option is suitable for use in protected outdoor areas, as it has corrosion-resistant output shafts and a special low-temperature cooling oil. Separate installation conditions apply for use in outdoor environments (see chapter Service/ operating instructions). 9. Optional LSC 40 control unit: Optional equipment available for the END 20 limit switch includes our power drives with the LSC 40.10. As standard, this includes the additional limit switch and can be extended to take LPR 02 analogue signals, or can be extended with the LPR 04 to take analogue and digital signals.
