4 2 Technical description 1.Design Linear actuator LiMax 60, 80 Framo Morat linear actuators are electromechanical drives which convert the rotating motion of the integrated electric motor into a linear forward or backward motion. Framo Morat actuators are primarily designed for industrial use. They are particularly robust and equipped with many safety standards. All installation positions are permissible. The complete stainless steel housing protects all mechanical and electrical parts. Only the connecting cables and the movable piston rod needs to be retracted. IP 54 is the standard protection class for all linear actuators. 2. Piston rod The stainless steel piston rod is ground. The piston rod is not locked to prevent torsion. The customer must provide a locking facility with the part that is to be moved. Radial forces are generally not allowed. 3. Motors Depending on size, the motors can be delivered with three-phase, single-phase (special voltage on request, DC motors will be mounted with a special flange). With the exception of the direct current motor, all motors are fitted with a thermal protection switch (trigger temperature +125 C). The motor winding is ISO class B. Standard protection class: IP 54. The three-phase motors can be connected as y or delta wiring. 3.1 DC actuators Separate power tables are available for DC actuators. If the DC motor operates as an individual unit, a suitable EMC interference suppressor shall be provided close to the motor terminal drive. For unit installation, the unit has to be suppressed. For this reason direct interference elimination is not always necessary and the interference suppressor is not located in the drive, therefore the customer has to plan for this possible requirement. 4. Duty cycle The indicated duty cycles relate to a total cycle time (ON + OFF) of 10 minutes, a maximum ambient temperature of 40 C and a maximum installation height of 1000 m above sea level. 5. Gears, stroke lengths The installation of 1- or 2-stage planetary gears allows the selection of different stroke speeds for every type (3 to 84 mm/s). Depending on type, special stroke lengths of 500 to 800 mm are possible. 6. Spindle LiMax actuators are delivered with a rolled acme lead screw. The spindle nuts are made of extreme wear resistant and self lubricating high-performance plastic. The following spindle types are available:

5 60, 80 3 LiMax 60 Spindle Tr 12 x 2 Sd Tr 12 x 3 Sd Tr 12 x 4 Ss Tr 12 x 6 So Nominal diameter 12 mm 12 mm 12 mm 12 mm Pitch 2 mm 3 mm 4 mm 6 mm Self locking dynamic dynamic static without LiMax 80 Spindle Tr 18 x 3 Sd Tr 18 x 4 Ss Tr 18 x 8 So Nominal diameter 18 mm 18 mm 18 mm Pitch 3 mm 4 mm 8 mm Self locking dynamic static without Attention! As for the declaration about self locking we refer to chapter 14. For precise positioning tasks, high stroke speeds, cycles and durability demands, LiMax-actuators are available with ball screw spindles and flanges for servo motor adaption. 7. Limit switches A limit switch is incorporated for each stroke-end position. A safety limit switch is available optionally. The safety limit switches prevent fatal actuator damages in case of faulty wiring or if a limit switch fails. The limit switches are fully adjustable over the entire stroke length. 8. Brake At stroke speeds of more than 20 mm/s, three-phase and single-phase actuators should be equipped with a brake because of their tendency to overrun (DC actuators see performance table notes). We also recommend that a brake is installed if the drive is not self-locking; the load takes affect while the actuator stands in idle position and the application requires a high positioning accuracy. A magnetic-electric single-disc pressure brake is available for all sizes. 9. Connection cables The standard actuators are supplied with external connection cables (1m length). Longer or special cables are available upon request, e.g. for low temperatures or with shielding. 10. Fixing options, connection heads Flange, foot and attachment bolts can be supplied in addition to standard attachment configuration A (attachment eye to eye). The actuator can also be delivered with different connection heads (see dimensional drawings). 11. Reliability and quality assurance Every actuator is produced according to order and tested under nominal load conditions. A proven modular system makes it possible to produce a large number of different models and to adapt them to customer requirements. All individual parts and sub-assemblies are generally kept in stock.

6 4 Linear actuator LiMax 60, Conditions of use The conditions of actuator use prohibit the movement of loads whereby persons can be directly or indirectly endangered. The application of actuators in equipment intended to transport passengers is not permitted without permission of the manufacturer. In this context we refer to EU Machinery Directive 98 / 37 / EC and the Act on Technical Equipment (Equipment Safety Act) where the user is responsible for the implementation of protective guards/barriers" to prevent touching (crushing hazard) during operation. This also applies for the application of actuators with suspended loads where persons can be endangered. 13. Special safety equipment It is possible to bring the actuator to a higher safety standard by using a force-dependent shut-off. Generally, sufficient safety margin should be included when sizing the actuator. 14. Self-locking ability The self-locking ability depends on the spindle pitch, the surface quality of the spindle/nut, the sliding speed, lubrication and temperature. We differentiate between dynamic (out of motion) and static (stationary) self-locking. Vibrations can eliminate self-locking. A certain number of factors such as lubrication, sliding speed and load can create sliding characteristics that the self-locking is negatively influenced. Therefore a theoretically self-locking spindle cannot replace a brake. It is impossible to assume guarantee obligations regarding self-locking. Important: Self-locking is not intended to satisfy security-related characteristics! To minimize additional dangers, observe the usual care for technical products. 15. Options The following options allow individual applications: 1. IP65 (splash proof) 2. Force-dependent shut-off (as protection for block movement or if a preset stroke force is exceeded) 3. Cushioned connecting head (e.g. approaching a permanent stop) 4. Adjustable connection head (for small changes to the attachment position) 5. Brake (for precise switch-off and non-self-locking actuators) 6. Mounting angles in combination with fixing version D (attachment bolts) 7. Integrated encoder (for position and speed control) 8. Different mounting possibilities (installation conditions can be taken into account) 9. Humidification seal coating of rotor and stator and/or condensation hole (if there is danger of condensation). 10. Explosion proof according to directive 94 / 9 / EG (ATEX 95) 11. Connection cable motor shielded (for frequency converter operation etc.)

10 8 Linear actuator LiMax Installation instructions (Translation) 1.0 Safety information 1.1 Warning notices 60, 80 Signal words are meant to indicate danger, proscription or important informations. The following signal words are used: Danger:! Warning:! Caution:! Notice : DANGER indicates a hazardous situation which, if not avioded, will result in death or serious injury. WARNING indicates a hazardous situation which, if not avioded, could result in death or serious injury. CAUTION indicates a hazardous situation which, if not avioded, could result in minor or moderate injury. NOTICE is used to address practices not related to personal injury. For furter visualisation we use the following symbols:! General Warning Hot surfaces Electrical dangers Slip danger Pending loads Crush hazard Environmental danger The symbol indicates the type of danger, the signal word indicates the severity of the danger. 1.2 General safety notes Before installation of the Framo Morat Linear Actuator LiMax Type 60 / 80 the following predictions have to be fulfilled, so that it can be assembled with other parts to a complete machine, without harming the security or health of persons. Every linear actuator is shipped with the installation instruction and the circuit diagram. These are taped to the drive in an envelope. Installation without this documentation is forbidden. Unintended or inappropriate use leads to the loss of any liability claim. This installation instruction and the annexed declaration of incorporation have to be attached to the drive until it is assembled into a complete machine and become by then a part of the technical documentation of the complete machine. Before installation and operation read all documents carefully and follow all instructions. The abidance of basic safety- and health protection requirements is considered by application of accredited engineer standards during design and is approved by the declaration of incorporation.! The mechanical and electrical installation as well as the adjustment and setup has to be done by certified electricians, authorized by responsible authority. Doublecheck the technical data on the name plate and follow the instructions on the labels of the drive.

11 60, 80 9! Moving parts have to be secured against unintentional contact to avoid injuries. The manufacturer points out that this is the responsibility of the user. Don't modify the drive. Modifying the drive is dangerous and voids the warranty. Don't block the drive while operating. This may cause hazard to persons and/or property and may damage the drive seriously. Don't overload the drive. The values for stroke force, voltage and duty cycle declared on the name plate can't be exceeded. Non-observance may cause danger to persons and property and the drive may be damaged seriously. Make sure that power is disconnected before working on the wiring. Secure the power source against unintentional switch on. Connect the drive only to a power source with ground terminal. Pay attention to the appropriate circuit diagram (schematic). Don't touch the drive during operation. The housing temperature can rise up to 90 C (close to 200 F). 1.3 Conditions of use Framo Morat linear actuators are drive systems, solely determined to drive machines, devices and equipment that exclude direct or indirect hazards to persons. If hazards to persons can t be excluded, it is obligatory to build additional devices (e.g. cover, shut off, cutting unit) to eclude the risk. As long as this additional device is not attached it is forbidden to use our drive. We refer users of gear motors to safety rules, regulations and laws governing the protection of staff working in the area of moving equipment. Protective guards or barriers shall be used. Similarlyprotective measures are required where suspended loads are involved. Keep in mind the common due diligence in connection with technical products to avoid further hazards.! Attention Danger! Applications intended for the transport of passengers are not permissible! Attention Notice! If our product optionally allows such an application, has to be clarified with the manufacturer in advance.!! Attention Caution! By default our gear motors are intended for environmental temperarture from 0 C up to 60 C, and a duty cycle of up to 60%. The protection class is IP54. Optional variances are noted on the name plate. Attention Danger Generally the drive ist not for use in dangerous explosive areas. Exception (not standard): Drives with the following characterization (on the name plate) can be used (exclusively) in the named zone. EEx II 3D, bck II T5 Please note: This application has to be confirmed with an added special confirmation.

12 Transport, Setup and Installation 2.1 Transport Linear actuator LiMax 60, 80! Attention Caution! Wear safety-shoes while carrying and working on/with the drive. A falling drive may cause injuries. Use a solid packaging to tansport the drive to the installation-site. 2.2 Setup and Installation Mount the drive without tensioning. Attaching parts must not be mounted by hammering. 2.3 Fastening torque for mounting screws! Attention Warning The property class for the mounting screws has to be 8.8 or better. Use the following table for correct fastening torques and screw-in depth. Type Screw Fastening torque Min. screw-in depth Max. screw-in depth LiMax 60 2 x M6 8 Nm 8 mm 12 mm LiMax 80 2 x M8 14 Nm 12 mm 16 mm Mounting screws 2.4 Fastening torque for the clamping flange While adjusting the clamping flange (fastening D,E,F) regard the following fastening torques: LiMax 60 = 10 Nm; LiMax 80 = 30 Nm 3.0 Electrical Installation! Attention Danger! Make sure to interrupt the current supply before working on the wiring and secure it against unintentional switch on. Connect the drive only to a power source with ground terminal. Read the circuit diagram carefully and pay attention to use the right voltage (see name plate on drive) Connect all external control- and power supplies according to circuit diagram. If limit switches and/or thermal protection are not connected the drive can be destroyed. The thermal sensor (bimetal) is an NC contact (normally closed) and shall interrupt the motor power if activated.

13 60, 80 11! Attention Danger! Protect the motor against unintentional start, because the thermal switch automatically closes the contact after cooling down (bi-metal contact). Confirm that the direction of the drive correponds with the dedicated limit switches (see adjustment instructions). Confirm the correct connection of the limit switches by pressing limit switch 2 (for position stroke retracted ) while the piston rod moves toward position stroke retracted (see picture). Therefore you have to remove the locking screw (allen screw M5) and push back the control rod - preferably with a allen key AF3 - approximately 5-6 mm. If the drive doesn t stop you have to change the connections of the limit switches. Limit switch 2 for position retracted Allen screw Control rod Attention Notice! Don't decellerate the motor by reversing the motor power. The life of the gear motor will be dramatically reduced. 4.0 Important informations 4.1 Duty cycle The duty cycle reference time is 10 minutes in a max. ambient temperature 40 C at an altitude of 1000 meters. 4.2 Ambient temperature, water condensation Attention Notice! Consult the manufacturer for operation under 0 C (to select a suitable gear lubrication). Permanently changing temperatures or high humidity can lead to water condensation. For proof we offer optional versions (condensed water drain holes or moisture protection vanish coat for rotor and stator).! Attention Warning! The drain holes will effect the standard protection class (IP54). 4.3 Operating temperature! Attention Warning! If the temperature of the drive, in spite of approved usage, exceeds 90 C, refer to the manufacturer. Perhapst there's a defect.

14 12 Linear actuator LiMax 60, Oil leaks Use extra caution if the gear motor is leaking oil. The surface might be slippery. Under these circumstances environmentally detractions are possible. 4.5 Self-locking Attention Notice! Self-locking is affected by lead angle, face surface roughness, running speed, lubricant and temperature rise. A distinction must be made between dynamic (from motion) and static (standstill) self-locking. Shocks or vibrations can annul the self-locking. Similarly a number of factors associated with lubrication, running speed and load can favour slip characteristics to such an extent that self-locking is counteracted. This means that gearing which is self-locking in theory is no substitute for a brake or reverse lock. Therefore it is impossible for us to accept warranty obligations in respect of self-locking.! Attention Danger! Important: Self-locking can NOT be responsible for safety characteristics! 5.0 Adjusting the limit switches The limit switches are preset according to the ordered stroke length. Nevertheless if you want to change the stroke length, this can be easly done. Retraction spring Pos. extended Limit switch 2 Pos. retracted wrench size 3 Limit switch 1 Pos. extended Limit switch 2 Pos. retracted Switch cam Pos. extended Control rod Pos. extended Limit switch 1 Pos. extended Bore for adjusting the limit switch Safety limit switch 1 (optional) Pos. extended Direction +" increases stroke Direction -" reduces stroke The bores for adjusting the limit switches are closed with allen screws M5 to prevent contamination. Unscrew the allen screws and use a allen key wrench size 3 to adjust the control rod as requested (see picture above). One revolution adjusts the switch cam (and therewith the stroke) by one millimeter.

15 5.0 Warranty, maintenance, approved usage 60, The drive is maintenance free due to lifetime-lubrication. The lifetime of the drive depends on the application (eg. ambient temperature, torque, speed, cycles, environmental influences). The piston tube should be cleaned from time to time with an oiled cloth to avoid dirt and deposit. 6.0 Warranty and repair All drives are tested before delivery. During warranty-time the drive shall not be opened. Dismantling leads to expiration of any warranty by the manufacturer. If a drive has to be repaired send it back to the manufacturer or a suitable agency. A service technician can be ordered for on-site service on short notice. 7.0 End of product life-time: 7.1 When the indicated lifetime is reached you can send the drive back for overhaul. 7.2 If you want to dispose the drive please pay attention to ecological and legal regulations. 8.0 Service To offer fast and competent help to our customers - e.g. while installation - we provide a servicenumber. Under +49 (0)160 / you can reach the 24 hour hotline. Please note that the usual fee will arise.
