Replacing the Rotor (4)
Before replacing the rotor (4)
Clean the brake.
Please observe the section “Cleaning the
Brake”, see right column.
Measure the rotor thickness of the new rotor (4).
The nominal dimension acc. Table 1 must be given.
DANGER
The brake must be load-free. Please check that
it is load-free before de-installation. In order to
replace the rotor (4), the brake must be un-
screwed from the machine wall.
Replace the rotor by following the Brake Installation instruc-
tions backwards.
When armature disk (3) replacement is necessary, please pro-
ceed as follows:
1) Unscrew the shoulder screws (8) from the coil carrier (2) and
remove the armature disk (3).
Attention:
The thrust springs (5) press against the armature
disk (3). In order to remove the shoulder screws (8), the ar-
mature disk (3) must be pressed against the coil carrier (2) to
avoid immediate relaxation of the thrust springs (5).
Observe the installation position of the armature disk (3), and
ensure that no thrust springs (5) fall out.
CAUTION
Danger of injury.
2) Lay the new armature disk (3) onto the coil carrier (2) or the
thrust springs (5) (observe installation position).
3) Press the armature disk (3) down against the spring force
and screw in the shoulder screws (8) up to their limits using
a tightening torque of
18.5 Nm
.
For further assembly of the brake, please follow the Brake Instal-
lation instructions, followed by Brake Inspection and Run-in Pro-
cedure, see pages 12 and 13.
Information on the Components
The
friction material
contains different inorganic and organic
compounds, which are integrated into a system of hardened
binding agents and fibres.
Possible hazards:
No potential dangers have been recognised so far when the
brake is used according to its intended purpose. When grinding
in the brake linings (new condition) and also in case of EMER-
GENCY STOP braking actions, functional wear can occur (wear
on the friction linings); on open brake designs, fine dust can be
emitted.
Classification: Hazardous property
Attention: H-classification: H372
Protective measures and rules of behaviour:
Do not inhale dusts.
Vacuum the dusts at the point of origin
(tested suction devices, tested filters acc. DIN EN 60335-2-69 for
dust classes H; maintenance of the suction devices and filter re-
placement at regular intervals).
If local dust suction is not possible or is insufficient, the entire
work area must be ventilated using appropriate technology.
Additional information:
This friction lining (asbestos free) is not a dangerous product in
terms of the EU Directive
Cleaning the Brake
Do not clean the brake using compressed air,
brushes or similar devices!
Wear safety gloves / safety goggles.
Use a suction system or wet towels to clean off the brake
dust.
Do not inhale brake dust.
In case of dust formation, a dust mask FFP 2 is recom-
mended.
Disposal
Our electromagnetic brake components must be disposed of
separately as they consist of different materials. Please also ob-
serve the relevant authority regulations. Code numbers may vary
according to the disassembling process (metal, plastic and ca-
bles).
Electronic components
(Rectifier / Switch):
Products which have not been disassembled can be disposed of
under Code No. 160214 (mixed materials) or components under
Code No. 160216, or can be disposed of by a certified disposal
firm.
Brake bodies made of steel with coil/cable and all other
steel components:
Steel scrap
(Code No. 160117)
All aluminium components
Non-ferrous metals (Code No. 160118)
Steel or aluminium pads with friction linings:
Brake linings
(Code No. 160112)
Seals, O-rings, V-seals, elastomers:
Plastic
(Code No. 160119)
Guidelines on the WEEE Directive 2012/19/EU
Avoidance of waste from electrical and electronic devices and
the reduction of such waste through recycling.
Our electromagnetic products (brakes, clutches) as well as the
components required to control them (rectifiers) are frequently
used in electrical and electronic devices within the appropriate
area of application of WEEE, independent of the applicable prod-
uct categories.
The stated products do not fall within the area of application of
this Directive. They have been classified as
electromagnetic /
electronic components
(VDE 0580) or as electronic equipment
(DIN EN 50178), and have been determined for installation in
devices for "use in accordance with the intended purpose". Only
products which are to be viewed as devices in terms of the Di-
rective and not as parts or components are subject to registration
obligations.
