12.5 Emergency evacuation by opening the brakes
Emergency evacuation through manually or electrically opening the motor brakes until the cabin has
reached the next
fl
oor in the direction of the pulling load.
Danger!
If an emergency evacuation is carried out by opening the brakes, the motor windings must be
short-circuited for the evacuation to prevent an uncontrolled acceleration of the elevator. The
short-circuit generates a speed-dependent braking torque, suf
fi cient in most cases to limit the
elevator speed to a safe level.
CAUTION!
Caution!
Short-circuiting the motor windings must be authorized by the motor manufacturer. This is tested and
guaranteed in Ziehl-Abegg motors.
