VG OSG
Version 3
15
The dynamic profile of the test rig has been appended to the VG rope brake
application programme. A printout of the programme is appended for reference
purposes. This amended programme will be used for all future applications using
the overspeed governor.
The individually measured response times, as required by section F.8.3, are used
to calculate the theoretical dynamic profile of the rig and then compared with
the actual recorded values. This will enable the effect of any changes in the
individual response times to be assessed accurately.
