Checks after start-up
After approximately 50 hours' operation, check that the screws
fixing the motor and the coupling device are still tight. In the
case of chain or belt transmission, check that the tension is
correctly adjusted. Check the electrical connections. Check the
vibrations. Check that there is no abnormal noise. If the brake
wear needs to be checked: measure that the clearance is lower
than the max dimension authorised. (see the "Adjusting the air
gap" procedure in section 4.4 ref. 5287 FFB maintenance)
Preventive maintenance visit
- Check regularly that the recommendations concerning
mechanical and electrical installation are still complied with.
- Inspect the seals.
- Remove any dust or foreign bodies which might clog the
cover grille and the housing fins.
- Lubricate the bearings of the motors fitted with grease
nipples.
Cleaning
Precautions to be taken: before carrying out any cleaning
operation, check that the brake motor is totally sealed
(terminal box, drain holes, etc).
Dry cleaning (vacuuming or compressed air) is always
preferable to wet cleaning.
To ensure the brake motor operates correctly, remove any
dust or foreign bodies that might clog the brake moving
parts, the cover grille and the housing fins.
Always clean at reduced pressure from the
center of the brake motor outwards to avoid
introducing dust and particles under the seals.
Draining condensation water
Temperature variations cause condensation to form inside the
motor, which must be removed before it adversely affects
motor operation.
Condensation drain holes, located at the bottom of the motors
(bearing in mind their operating position) are sealed with plugs
that must be removed and then replaced every six months (if
they were not replaced, the motor degree of protection would
no longer be maintained). Clean the orifices and plugs before
reassembling them.
Note: In conditions of high humidity and significant temperature
variations, a shorter period is recommended.
When there is no risk to the motor protection, the condensation
drain plugs can be removed.
