The specified switching times apply to nominal clearance and nominal torque. It relates to average values and depends on the type of rectification and coil temperature.

Mbr: Static braking torque after completed run-in phase
Mbred: possible reduced brake torques
JB: Inertia
P20: Excitation rating at 20°C
t2: Release time, time from connecting the current to the beginning of torque decrease
t11~: Engagement delay time for AC side switching (Fig. 1,3) Time from disconnecting the current to the raise of the torque
t11=: Engagement delay time for DC side switching (Fig. 2) Time from disconnecting the current to the raise of the torque
WR0.1: friction work until 0.1mm abrasion
WRmax: permissible friction work for emergency stop from 3000 1/min (B08..B10 - 1500 rpm)
X: Nominal air gap
Xn: Air gap, at which a readjustment is recommended
gmin: minimum lining thickness
m: The dimension m applies to rated torque and operation with rated voltage

Electrical Connection

Figure 1: AC side switching

The brake is switched independent from the motor voltage, engagement delay time t11~
Suitable for operation with frequency inverter

Figure 2: DC side switching

The switching of the brake on AC and DC side leads to faster engagement delay times t11=.

Figure 3: Brake ready for connection

Voltage supply from motor terminal board.
The brake is switched together with the motor voltage, engagement delay time t11~
In comparison to Figure 1 the connection to the brake is made within the motor terminal box
Not suitable for frequency inverter operation and for pole changing motors

Inspection and maintenance

air gap control periodical, adjust if air gap met value Xn

Adjust air gap

disconnect the brake from load to avoid uncontrolled rotation
release cylindrical screws (4)
Adjust air gap by turning the adjusting screws (5)
Pay attention to symmetrical adjustment
tighten cylindrical screws (4)
control air gap again, repeat process if necessary
the adjustment can be repeated until the brake lining thickness is gmin. Then the lining (6) has to be changed
Manual brake release: Check dimension m with attracted armature, adjust if necessary

Change brake torque

disconnect the brake from load to avoid uncontrolled rotation
release cylindrical screws (4), dismantle adjusting screws (5) and armature disk (7)
Change or remove springs according to table
Attention! Arrange springs always symmetric.
Assembly in opposite sequence
Adjust air gap and hand release

The given torques are index values.
