1.- Seal.
The adjusted sealed points of the overspeed governor
should not be manipulated. The adjustments are
produced in the workshop and cannot be varied.
2.-Cables.
The ropes to be used are Ø 6 mm - 6.5 mm (6x19+1)
(8x19+1).
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 of the Overspeed Governor.
The overspeed governor has upward and downward blocking. Can be used indiscriminately mounted right or left (both directions of rotation).
The bloking speed may range from one direction to another of 4% and 8%. The overspeed governor can be mounted ONLY in
downwards, too (in these cases the reference will be 2129.B-----).
4.1.- Manual blocking.
It is possible to carry out the manual tripping of overspeed governor, to activate the safety gear, pushing downwards the tripping device of
overspeed governor, indicated in the arrow in the diagram.
4.2.- Remote blocking.
There is a solenoid to produce the tripping of the overspeed governor. There are different tension supplies of the solenoid.
4.3.- 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.
4.4.- Electrical contact reset.
The over speed switch has to be reset when it has been opened. This will be reset manually (machine room), automatically or remote reset
to 24 VDC (4,2 A) o 230 VAC (0,5 A) and will be after the mechanical reset of the overspeed governor.
4.5.- Mechanical reset.
When the overspeed governor is triggered, its rope is maintained in a locking position being required the displacement of the car in the
opposite direction of which the blocking was produced for the mechanical resetting.
