MANUAL OPENING
If the gate has to be operated manually due to a power failure or malfunction, use the release device
as follows:
EMERGENCY RELEASE/FRICTION CLUTCH
The vandalism protection for the barriers KOLOSS 60 – 90 – 120 consists of an internal friction
clutch, which can be operated by a rating nut, accessible from the outside. Is the barrier boom forced
upwards, the clutch slides through when a certain force is applied. The barrier boom is still connected
mechanically with the motor-gearbox-unit. After the vandalism protection was activated, no parts of
the barrier need to be exchanged. The gearbox suffers no damage. Adjusting the friction clutch:
Loosen the rating nut of the friction clutch located behind the emergency release cover (anti-clockwise,
direction 1) using the supplied key SW 27/32 (see Drawing and Table ). Do not remove the rating nut
completely. The barrier opens through the spring tension to approx. 30-45°, when the rating nut was
loosened sufficiently.
