6.5Emergency evacuationAttention!The measures for emergency evacuation described below may only be performed by instructedpersons for maintenance of the lift or qualified personnel of lift companies.6.5.1 Manual emergency evacuationIn case of power failure or failure of the recovery control, emergency rescue is only possible byreleasing the brakes manually. The picture shows how the levers must be actuated for hand release.Manual lifting of the brakeThe levers for hand release can be inserted with an offset of 90° in every position and can be actuated±25° on both sides.possible insertion positions of the levers for hand releaseWhen the brakes are released manually, the lift moves in the direction of the greater weight. If there isa balance between the cabin and the counterweight, the cabin must be made heavier by suitablemeans.To reduce the acceleration of the lift, we recommend to short-circuit the motor for the evacuation. Theshort-circuit is generated by the motor contactors.The short-circuit generates a speed-dependent braking torque. The maximum braking torque isachieved at lower speeds.Depending on the system type and weight ratios, it is possible that due to the short-circuitgenerated braking torque is not sufficient to limit the lift speed. So the speed must bemonitored closely during evacuation and evacuation interrupted if necessary.Manual release of the brake is finished when a floor is reached. Now the lift door can be opened witha triangular key.The lift manufacturer's safety instructions have priority!Danger!The levers for hand release must be removed after brake hand release action.A brake with a mechanical hand release system is available optionally. The hand releasesystem cannot be fitted later. The complete brake must be replaced to retrofit the hand releasesystem.6.5.2 Electrical emergency evacuationThe electrical emergency evacuation is described in the operation instructions of the control, theinverter and, if available, an evacuation unit with UPS.Start-up$7%$B*% Part.-No. 01008166-GB (EU-BD 845)14/682ULJLQDORSHUDWLQJLQVWUXFWLRQVZAtop – model series SM160.30B/40B
