In this document, overspeed tests ask you to scale a run speed by 110% in order to exceed
the respective overspeed for that setting. This is almost always adequate. However, if the
speed required for the test exceeds 110% of contract speed, you will need to increase the
scaling percentage, F7-141, to compensate. Otherwise, the overspeed will not be detected
which, in some tests, may result in a car or counterweight unintentionally hitting a buffer or
overhead.

lways have a technician standing by to shut down the elevator if necessary.
