GENERAL WARNING
This document is an addition to the general manual ref. 1889 (recommendations), ref. 4850 (LSES motor), ref. 4155
(LSRPM motor), and the installation manual ref. 5286.
FFB brake motors are assemblies made of an asynchronous motor and a failsafe braking system (safety brake).
This brake motor benets 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
certication.
These symbols appear in this document whenever it is important to take special precautions during installation, operation,
maintenance or servicing of the brake motors.
It is prohibited to drive the extension shaft and the fan in manual rotation with the parking brake applied, or
the brake released under load.
General danger Electrical hazard Risk of physical injury
Risk of severe or lethal injury Risk of severe or lethal injury
These recommendations, instructions and descriptions refer to standard use. They do not take account of non-standard
versions or special adaptations. Failure to comply with these recommendations can lead to premature wear and tear of
the motor and can invalidate the manufacturer warranty.
Make sure that the brake motor is compatible with its environment before its installation and also throughout its
life.
The following preliminary precautions must be taken before working on any stationary device:
• Mains voltage disconnected and no residual voltage present
• Careful examination of the causes of the stoppage (blocked transmission - loss of phase - cut-out due to thermal
protection - lack of lubrication, etc.)
Electric brake motors are industrial products. They must therefore be installed by qualied, experienced and authorized
personnel. The safety of people, animals and property must be ensured when tting the motors into machines (please
refer to current standards).
Particular attention must be given to equipotential ground or earthing connections.
Safety of personnel: protect all rotating devices before power-up. If a brake motor is started up without a coupling device
having been tted, carefully immobilize the key in its location. All measures must be taken to ensure protection against
the risks which arise when there are rotating parts (coupling sleeve, pulley, belt, fan, etc.). Personal protective equipment
must be worn. After work is carried out, the lids of the terminal box and its cover must always be closed.
Beware of backdriving: when the brake motor is tted with an active brake release lock off system (DLM), it is vital to
ensure safety (of people and property) in exposed areas.
Before any intervention on the brake, check that it holds no load.
After an operating period, certain parts of the brake motor may be hot and are likely to cause burns.

4.4 - Air gap adjustment
The air gap requires adjusting when it reaches 0.9 mm..
Lining wear must be checked when the air gap is adjusted, by
checking the disc thickness (R). The dimension R must never
be below the following values, as this would result in damage
including total loss of braking torque, without any warning
signs.
Disc thickness must be measured with an accuracy of at least
0.5 mm.
Always change the disc when the R dimension
reaches the following values:
Brake size Minimum R dimension
FFB1, FFB2, FFB3 10 mm
FFB4, FFB5
16,5 mm
Exceeding R dimension can cause security
problems (quick decrease of braking torque Mf).
Procedure:
- Unscrew the screws 27 holding the metal cover 13.
- Remove the metal cover 13.
- Clear the O-ring 1107 to gain access to the air gap.
- Check the air gap between the yoke 1105 and armature
1102 in 3 points at 120°.
- Release spacers 1104, move them closer to the yoke 1105.
- Screw (to narrow the air gap) or unscrew (to increase
the air gap) the screws 1106 while measuring the air gap
between the yoke and the armature to obtain a dimension
as specied in the table below:

FFB4, FFB5 0,4 - 0,5 mm
- Screw the spacers 1104 in abutment on friction face-plate
(tighten to 2 Nm ±10% torque).
- Tighten xing screws 1106 brake yoke on face-plate to the
torque as follows:
Brake size
FFB1 4,9 Nm ± 10%.
FFB2, FFB3 8,5 Nm ± 10%.
FFB4, FFB5
21 Nm ± 10%.
- Check the value of the air-gap again.
- Reposition the O-ring 1107 into its groove.
- Fasten the cover 13 with its screws 27.
- Position the cover closing hatch 1406 by ensuring that the
lever travel (in the brake release position) is effective.
When DLRA or DLM mounted, refer to §6.1, 6.2.
After 3 air gap adjustments, always check the
value of the R dimension frequently and
changing the brake disc item 1101 is
recommended (according to dynamic brake use).
Atex zone 22
Refere to Specic recommendations for commissioning and
maintenance ref.3711.
If the brake is not equipped with an opening/closing detector,
check the clearance periodically according to the rates and
the energy to be dissipated on each braking operation (see
technical catalogue ref 5329 § Brake energy capacity).
4.5 - Maintenance
Control after commissioning (about 50h).
Check tightening of fastening screws and belt tensioning if
applicable.
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 ns.
- Lubricate the bearings of the motors tted with grease
nipples.
In the absence of a wear detector (highly recommended for
lifting - UL applications):
- Beyond the 3rd air gap measurement, the user must check
disc thickness at sufcient interval (according to the braking
cycle and energy to dissipate to avoid exceeding the R
dimension see § Operation in the technical catalogue ref.
5329) .
In the absence of opening/close detector (highly
recommended for applications in Atex zone):
- The user will check the air gap at a sufcient interval
(according to the braking cycle and energy to dissipate, for
information refer to § Operation in the technical catalogue
ref 5329) to prevent disc locking (risk of overheating and
early lining wear).
- Gaskets, bearings:

• Reassembly:
- Reverse the removal procedure.
6.8 - IP65 10 pin 16A connector kit
The LSES 71 to 132 4-pole motors can be tted with a
connector compliant with UL and CSA standards as per the
following two versions:
- WMS or male version, closed with lead cover
- WMFS or full version, with female extension cover on the
side, docking brass PE ISO 25 for cable entry (not supplied)
between 12.5 and 18 mm.
See connection diagram § 8.
6.9 - Particular conditions of use
- Thermal protections (§8)
- 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:
• +135°C if 40°C ≤ 50°C
• +145°C if 50°C ≤ 60°C
Caution: The motor's surface temperature
during operation requires wearing PPEs when
handling parts and during maintenance
operations.
- Maintenance of main bearings:
When detecting the following on the brake motor:
• abnormal noise or vibrations,
• abnormal heating on the bearing, check their condition.
Change damaged bearings as soon as possible to prevent
additional damage to the brake motor and driven devices.
When one bearing requires to be changed, also change the
other bearing. The oating bearing shall ensure expansion of
the rotor shaft (check its identication upon disassembly).
Always change the sealing gaskets when changing the
bearings.
- Sealing
After removing the bleeding plugs, ret them to ensure
the brake motor achieves the IP55 protection rating.
Non-ventilated brake (IC410): using the brake exclusively
as a parking brake. Service braking is forbidden.
Dust must be removed regularly to prevent it from building up.
For motors with voltages other than the catalogue standard,
with low voltage starting or running under variable voltage
or frequency: separate brake supply is required. (Also in the
case of a 20V DC coil).

The brake must be assembled with a motor which respects
the same EXAT level requirements at least.
If the brake is not equipped with a release/application
indicator, check the clearance periodically according to
the rates and the energy to be dissipated on each braking
operation (see technical catalogue ref 5329 § Operation).
Those persons required to work on electrical installations and
equipment in zones where there is a risk of explosion must be
specially trained in the necessary skills.
In effect, they must be familiar not only with the electrical
risks, but also with those that are due to the chemical
properties and physical characteristics of products used in
the installation (gas, vapour, dust), as well as the environment
in which the equipment operates. These elements dictate the
risk of re and explosion.
In particular, they must be informed and aware of the specic
safety reasons and requirements in order to adhere to them.
For example:
- do not open when powered up,
- do not open when powered up in atmospheres
D21containing explosive dust,
- do not repair when powered up,
- do not manoeuvre when on load,
- wait several minutes before opening,
- replace the seals tightly to ensure watertightness.
