1) The specified values are nominal values that were determined during rating operation. The actual braking work that can be reached
before maintenance may vary depending on the actual load during operation.
2) When checking the working air gap, note: After a test run, parallelism tolerances on the brake lining carrier may give rise to devi-
ations of ±0.15 mm.
8.3 Operating currents
8.3.1 General information on determining operating currents
The tables in this chapter list the operating currents of BE.. brakes at different
voltages.
The acceleration current I
B
(= inrush current) flows only for a short t im e when
the brake is released.
The values for the holding currents I
H
are rms values. Only use current measurement
units that are designed to measure rms values.
INFORMATION
The following operating currents and power consumption values are nominal values.
They refer to a coil temperature of +20 °C.
Operating currents and power consumption usually decrease during normal operation
due to heating of the brake coil.
Note that the actual operating currents can be higher by up to 25% depending on the
ambient temperature and with coil temperatures below +20 °C.
