GENERAL WARNING This document is an addition to the general manual ref. 1889 (recommendations), ref. 4850 (LSES motor), ref. 4155 (LSRPM motor), and manual ref. 5286 (FFB brake installation). FFB brake motors are assemblies made of an asynchronous motor and a failsafe braking system (safety brake). This brake motor benefits from the experience of a global manufacturer, using cutting edge technologies - automation, selected materials, thorough quality control - in our motor plants who have been awarded the ISO 9001 - Issue 2008 international certification.

CORRECTIVE MAINTENANCE 4 - CORRECTIVE MAINTENANCE - If the brake is fitted with a DLRA, DLM or DMD system, unscrew the lever rod(s) (item 1502, 1605). - Unscrew the cover screws 27, remove the metal cover 13. Before any operation on the brake, always - Remove the fan 7 by removing the axial locking circlips 9.
CORRECTIVE MAINTENANCE 4.4 - Air gap adjustment Adjust the air gap when normal loosening is no longer possible. Always check the pad's thickness when adjusting to ensure pad wear does not exceed the R dimension in mm (i.e. R/2 on either side of the disc 1102). Its change is compulsory before the lenght R between each brake lining reaches: Brake size Minimum R dimension...
CHARACTERISTICS 5 - CHARACTERISTICS 5.1 - Braking moments The braking moment is defined according to the number of springs and their colour, based on the values indicated in the table below. Running-in: All brake linings, complete brake (Brake disk only: see section 3.2) are already run-in in the factory before assembly onto the motor.
OPTIONS 6.6 - Forced ventilation kit 6.8 - Particular conditions of use - Exploded view - Thermal protections (§8) 1405 - Heating resistors (§8) - Surface temperatures: As standard, the maximum temperature of our brake motors is +125°C with a maximum ambient temperature ≤ +40°C. Without derating the brake motor, the maximum surface temperature shall be: •...
