VG OSG
Version 3

The test rig is fitted with a pulse encoder mounted from “the lift car” and running
on the guide rails. The encoder and a 16 channel data logger is then connected
to a computer to measure and record the information required in section F.8.3 of
EN81:-
1) The individual response times of different phases of the OSG and UCM
detection system.
2) The overall time of the test
3) The average acceleration
4) The velocity increase after the governor has been tripped
5) The time to decelerate.
In addition, absolute measurements of the total travel and the slide distance
through the rope brake will be taken. These results are then used to derive the
salient points indicated in Figure F.2 of the code. A dynamic profile of a typical
test is illustrated in Figure 2.
