Measuring the wear of BE03 brakes
The working air gap of BE03 brakes cannot be adjusted. Check the stroke of the pres-
sure plate during maintenance.
Replacing individual parts of the brake is not permitted.
ü
The motor and all connected options are disconnected from the power supply.
ü
The motor is protected against unintended restart.
1. Measure the dimension "X" at the stroke of the studs when the brake is released
or applied using a depth gauge or slide gauge.
ð
The difference between both values is the working air gap.
ð
The maximum permitted working air gap is 0.65 mm. Replace the brake in case
this value is exceeded.

Setting the working air gap of BE05 – BE122 brakes
ü
The motor and all connected options are disconnected from the power supply.
ü
The motor is protected against unintended restart.
1. Disassemble the following parts:
ð
Forced cooling fan and rotary encoder, if installed, see chapter

ð
Fan guard with encoder mount [212] or fan guard [35], retaining ring [32]/[62]
and fan [36]
2. To move the sealing strip [66], loosen the clamping strap [157].
3. Remove brake abrasion by suction.
4. Measure the brake lining carrier [68].
ð
For the minimum thickness of the brake lining, see chapter
"
ð
If necessary, replace the brake lining carrier, see chapter
disk of BE05 – BE122 brakes" (→
5.
BE30 – 122:
To loosen the setting sleeves [67], turn the setting sleeves [67] to-
wards the B‑side endshield.
6. Measure the working air gap A with a feeler gauge according to the figure at
3 points offset by 120°.
ð
BE05 – 11
: between pressure plate [49] and damping plate [718].
ð
BE20 – 122
: between pressure plate [49] and magnet body [54].
