Page 11: Mounting Optional Accessories
5 Mounting optional accessories 5.1 Mechanical or inductive limit switches For details regarding the technical characteristics of the limit switches please see the catalogue. Ensure that the cable is laid in a safe way. Avoid damages to the cable e. g. due to small radiuses; this may lead to failure of the system. The cable must not enter the travelling path of the linear system. -
Page 12: Mounting Coupling
5.3 Mounting coupling There are two methods to install the motor, either without gears or with a planetary gear. The manufacturing tolerance are very low, therefore we recommend buying the adapter directly from Bahr Modultechnik. Angular misalignments and misalignments with respect to the centre of the adapter can lead to serious damages at the coupling and the bearings. -
Page 13: Maintenance
6 Maintenance Before starting any work, ensure that the electric drives used are secured against being switched on. 6.1 Lubrication/Lubricants All linear systems are delivered EX Works with standard lubrication. Subsequent lubrication intervals are dependent on hours run, degree of loading and environmental factors (wide temperature ranges, high humidity, aggressive environment etc.) and the mileage. -
