3.2 SAFETY GEAR ADJUSTMENT

In order to avoid problems with the installation’s
normal operation, it is very important that the person
carrying out the installation rigorously observes the
distances mentioned in this item.

3.3 COUPLING THE DRIVING BAR
It is the responsibility of the person who installs the safety gear to properly position the driving bar in relation
to the safety gear, as well as to properly synchronise the safety gears controlled by that driving bar. The driving
bar is properly positioned when the roller’s pivot is in the protection plate’s central position.
Once it has been fitted, and the safety gear’s rollers have been attached to the driving bar’s tripping bars, it
should be checked that both rollers operate simultaneously, controlled by the driving bar. This should be
checked in both directions, ascending and descending.
The minimum force to be generated by the overspeed governor is double the force that ensures that the
performance of the safety gears is synchronised.

The Standard demands that the installation incorporate an AC-15 or DC-13 safety contact as defined
in EN 60947-5-1.
