Anti-Condensation Heating (Option)

The anti-condensation heating is used to prevent condensation
precipitate in the brake interior.
To connect the anti-condensation heating (AC voltage), see the
Wiring Diagram.

Condensation (Fig. 14)

The condensation must be checked regularly via the screw plug
(14) with the copper sealing ring (15).

Disposal

Our electromagnetic brake components must be disposed of
separately as they consist of different materials. Please observe
the relevant authority regulations. Code numbers may vary
according to the disassembling process (metal, plastic and
cable).

Electronic Components
(Rectifier / ROBA-switch / Microswitch):
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 pads with coil / cable
and all other steel components:

Steel scrap

(Code No. 160117)

Aluminium components:

Non-ferrous metals (Code No. 160118)

Brake rotor (steel or aluminium pads with friction linings):

Brake linings

(Code No. 160112)

Seals, O-rings, V-seals, elastomers, terminal boxes (PVC):

Plastic

(Code No. 160119)

Malfunctions / Breakdowns:

Results of Malfunction

Possible Causes

Solutions

Brake does not release

Abraded particles between the armature disk and
the coil carrier.

Air gap too large

Air gap too small (remove the distance washers
before reaching the max. air gap)

Coil interruption

Rectifier failure

Incorrect voltage on rectifier

Clean the brake

Re-adjust the brake; replace the brake

Insert distance washers between the coil
carrier and the flange plate

Replace brake

Replace rectifier

Apply correct voltage

Brake does not brake

Emergency release screws are not loosened

Grease or oil on the friction surfaces

Loosen the emergency release screws

Replace rotor

Release monitoring
does not emit a signal

Abraded particles between the armature disk and
the coil carrier.

Switching position misaligned

Defective microswitch

Clean the brake

Adjust the switch again

Replace the switch
