- Page 15 Product description A mechanical linear unit converts rotational motion into linear motion and is used to move loads quickly, safely and precisely from one position to another. It consists of an aluminium base profile, a moving carriage supported by a guide element (recirculating ball bearing or roller bearing guidance system) and a drive element (screw or timing belt drive).

Page 16: Transportation And Storage
Transportation and storage Transportation and storage The mechanical linear unit is a precision item. Its mechanism may be damaged by heavy jolting, resulting in impairment of its functions. Risk of damage by heavy jolting or bending! Transport the assembled linear unit only with the transit protection fitted. -

Page 19: Setting The Positions Of The Inductive Limit Switches
Installation and adjustment 6.3.1 Setting the positions of the inductive limit switches The function of inductive proximity switches is to shut down the electric drive before the mechanical end position is reached. The necessary braking distance depends on the velocity and deceleration of the carriage base. - Page 20 Installation and adjustment As from type Alpha 20-B Inductive limit switch Bearing Figure 6: Inductive limit switches for types Alpha 20-B, 30-B, 35-B The limit switches must switch in such a way that the carriage does not run all the way to the stop and so that the bellows are not squashed. Procedure Setting for types Alpha 20-B, 30-B, 35-B Connect the power to the limit switches.

Page 21: Setting The Positions Of The Mechanical Limit Switches
Installation and adjustment 6.3.2 Setting the positions of the mechanical limit switches Mechanical safety limit switches (NC contacts) must be used if a hazard is posed to personnel as soon as the electric drive fails to shut down. The drive may only be started up when all limit switches are connected and correctly set! A combination with inductive proximity switches is possible. -
Page 22: Mounting A Drive Unit
Installation and adjustment Procedure Connect the power to the limit switches. Slacken the bracket fixing screw (figure 7). Run the carriage as far as the safety zone. Move the limit switch until it trips. Tighten the bracket fixing screw. Check the correct position of the limit switch: Move the carriage manually and observe the switching operation. -
