AMI 100 UCM
Ex Amendment A3
AMI 100 UCM is a certified and patented device that meets the requirements of paragraph 5.6.7 of the EN 81-20: 2014 standard; paragraph 5.8 of the standard EN 81-50: 2014 or EN 81-1 / 2: 2010 (Former amendment A3).
In compliance with UNI 10411-1, 10411-2, 10411-3, 10411-4, 10411-5,10411-6, AMI 100 UCM allows – in the case of matching with appropriate parachute brake – to prevent any type of uncontrolled movement, for example, the uncontrolled movement caused by slipping of the ropes on the winch’s drive pulley.
How AMI 100 UCM works
The AMI 100 UCM device prevents uncontrolled movement of the cabin away from the floor, which can occur both during descent and during ascent.
The pin of the device, in case it is not retracted (ie when it is stopped at the floor), interferes with brackets positioned directly on the guide.
AMI 100 UCM is connected to the parachute and, when the interference between the pin and the bracket causes it to rotate, the parachute itself is activated.
No need for motion sensors
The AMI 100 UCM device is itself the actuator of the stop systems: since it is mechanically fixed to the lift arch, it is not necessary to install any movement sensor.
In fact, the device automatically detects the movement in the moment in which this occurs.
For this reason – and since no electronic motion detector is used – it is therefore not necessary to check the sums of reaction times of the various components that must intervene to stop the cabin.
Not needing any movement detector, it is not necessary to replace the control panel with panels capable of receiving and processing the signals coming from the motion detector.
Safe in the event of breakdowns
The micro switches – with positive opening of the contacts and in accordance with Annex K, paragraph 2 of the EN 60947-5-1 standard – directly control the two extreme positions of the pin and are connected in series on the safety chain of the landing doors for being able to inhibit the operation of the lift in case of failure.
AMI 100 does not need any monitoring: the device, in fact, is electrically connected to the safety chain of the landing doors and the monitoring takes place during each lift stroke.
