4.1.- Manual blocking.
It is possible to carry out the manual tripping of overspeed governor, to activate the safety gear, pushing the axis of the
rubber pulley and it is out of frame of overspeed governor, as indicated in the arrow in the diagram.
4.2.- Mechanical and electrical blocking.
When the rotation speed of the overspeed governor reaches the speed at which it has been calibrated and sealed, the
electrical contact is activated, which indicates the control panel to brake the machine and decelerrate the car. If this is not
enough, the overspeed governor will block mechanically and as a result activate the safety gears and the stoppage of the car
on the guide rails.
4.3.- Electrical contact reset.
The over speed switch has to be reset when it has been opened. This will be reset manually (machine room) o automatically
o can be reset by remote at 24 VDC or 230 VAC (maximum ampere of 4,2 A and 0,5 A) and allways will be after the
mechanical reset of the overspeed governor.

1.- Seal.
The adjusted sealed points of the overspeed
governor
adjustments are produced in the workshop and cannot
be varied.
2.-Cables.
The ropes to be used are Ø 6 mm - Ø 6,5 mm - Ø 8
mm. Avoid getting the rope greasy when lubrication
procedures are carried out in the lift.
3.- Fixture and Assembly.
To assemble the overspeed governor it will be
necessary to apply Hilti type wads or similar of
M12x100E. The overspeed governor will be fixed on
these wads in the middle of two drills situated in the
base, or better still, by means of screws if pre-drilled
guides have been installed in the floor.
4.- Blocking-Unblocking
Governor.
The overspeed governor has upward and downward
blocking. Can be used indiscriminately mounted right or
left (both directions of rotation). The blocking speed
may range from one direction to another of 4% and 8%.
