Precautions: LINAK control boxes are designed so that they will short-circuit the motor terminals (poles) of the actuator(s), when the actuator(s) are not running. This solution gives the actuator(s) a higher self-locking ability. If the actuator(s) are not connected to a LINAK control box the terminals of the motor must be short-circuited to achieve the self-lock ability of the actuator. Improved self locking ability The H-bridge ensures that the motor is shorted when the relays are incactive. This is necessary to improve the selflocking of the actuator. When using LA3 with stereo jack plug be aware of the reversed direction of travel as standard. The current supply to LINAK actuators must be cut off in case of overload when the actuators reach end position. Various other information: Noise levels: LA3: db(a) 5; LA3S: db (A) 55; LA3L: db(a) 48. Measuring method DS/EN ISO 3746, actuator not loaded. Accessories for LA3: Limit Switch There are two types of LINAK limit switches, for LA3, LS and LSD. The LSD type controls the stroke length of the actuator between two fixed end positions by cutting off the current to the motor. The LS type gives signal in two fixed end positions, but requires a control unit to stop the actuator when the micro switches are activated. Bellows Give a better protection and therefore give a higher liftetime of the actuator Protects inner tube against dust and dirt Can be used for actuators: LA3 Does not change the IP rating Available in black colour Ask for special folder Please contact your nearest LINAK dealer for further details or read more on www.linak.com.
