1 GENERAL INFORMATION BEFORE BEGINNING THE ASSEMBLY
1.1 DESCRIPTION, OPERATION MODE
The overspeed governor s a safety devce whch turns on when the allowed speed of the elevator car s excee-
ded.
If the elevator car, durng ts upward/downward run, exceeds ts nomnal permssble speed, (untl the trppng
speed s reached), the overspeed governor turns on and, n turn, releases – on the overspeed governor rope – a
brake mechansm, called safety gear, whch s located on the elevator car. The elevator car stops and s kept
back by the gudes.
The same overspeed governor (fig. 1) s made up of pulley wth:
- governor wheel (1) wth trapezodal undercut groove to house the overspeed governor rope
- test grooves for operaton tests (2)
- cam rm (3);
- eccentrc stop (4).
The rope, secured to the clamp of the safety gear and stretched by a weght, operates the governor wheel (1)
through ts own pressure n the trapezodal undercut groove.
Besde the trapezodal groove, a cam rm (3) wth eccentrc stop (4) s also mounted on the governor wheel.
Such rm allows the pendulum (6) to operate wth an upward/downward oscllatng moton, by means of a pul-
ley mounted on a ball bearng.
The pendulum s drawn to the cam rm by a preloaded tenson sprng, correspondng to the scheduled trppng
speed.
By reachng the trppng speed, the swng of the pendulum on the cam becomes so extended, that the osclla-
tng dog clutch (8) meets the perpheral gude of the eccentrc stop, where t s clamped.
A plate (5) appled on the pendulum operates the safety swtch (9) before the mechancal clampng of the pen-
dulum. Through t, the control power of the plant s swtched off.

1.2 RESPONSIBILITY AND GUARANTEE
These operatng nstructons are addressed to persons, who are well acquanted wth the assembly of eleva-
tors. Thorough knowledge of the elevator constructon and mantenance are necessary.
The firm P.F.B. declnes any responsblty for damages, dervng from not workmanlke or smlar actons, that
have not been carred out accordng to the followng operatng nstructons and that therefore may damage the
characterstcs of the product.
P.F.B.’s guarantee may not be vald f the component part s used n a dfferent way than that descrbed n these
nstructons.
For techncal securty reasons, t s not allowed:
• assemblng of wrong overspeed governors, or governors destned to other applcatons than the ntended one
• ntroducton of changes of any knd to the overspeed governor.
1.3 SAFETY PRECAUTIONS
Generally the fitters are themselves responsble for the safety of the work.
The observance and respect of all the safety regulatons n force and the legal rules are necessary to avod da-
mages to persons and to the product durng the assembly, mantenance and repar.
Instructons that should be partcularly consdered regardng safety and damage preventon are ponted out
wth the followng symbols:
ATTENTION! Indcaton of danger. It ndcates stuatons, that nvolve rsks for the persons and stres-
ses out behavoural procedures.
DANGER! Indcaton of danger of possble damages to the structural element and to ts component
parts (e.g.: mstakes n the assembly, etc.).
IMPORTANT! Indcaton of useful nformaton.
The followng operatng nstructons are an ntegral part of the whole plant. They must be kept n a protected
and easly accessble place (such as for nstance n the engne room).
1.4 WORKING INSTRUCTIONS ON SAFETY STRUCTURAL ELEMENTS
Overspeed governors belong to the safety structural elements group. It s absolutely necessary to observe the
rules and regulatons that refer to ths structural element, ncludng the nformaton gven n the operatng n-
structons.
For that reason, before begnnng to work on ths component part, the followng operatng must be
red and understood, n partcular wth regard to the chapter concernng “safety precautons”.
Safety devces need partcular attenton. Ther perfect functonng s essental for a safe operaton of the plant.
The regulaton of the safety devces, that can be set only after the assembly, must be carred out mmedately
after the assembly tself.
If safety devces are already preset at the factory, ther operatons have to be mmedately tested.
Should t be necessary to dsassemble the safety devces durng mantenance or repar, when termnated they
have to be mmedately reassembled and adequately tested.
In these nstructons, the followng safety devces are descrbed:
• safety swtch on the overspeed governor (adjusted n the factory)
• safety swtch on the tenson weght wth counterweght (only n the plants that are n conformty wth
EN81).

1.5 OPERATIONS SCHEDULING
Before begnnng the assembly, t must be made clear, n one’s own nterests, whch are the constructonal con-
dtons and condtons relatng to the space avalable, n order to carry out the assembly works n a safety con-
dtons and followng a logcal order.
It s therefore advsable, consderng all the gven crcumstances, to mentally smulate the varous processes
before the assembly actvty s nconsderately or hastly undertaken.
On recept of the supply, t s necessary to check the goods, by comparng each sngle part wth the purchase
order, n order to verfy ther conformty and completeness.
The data contaned n the type-plate have to be compared wth the order.
1.6 TYPE-PLATE, TEST MARK, IDENTIFICATION
The type-plate of the OVERSPEED GOVERNOR s attached to the structure on the sde.
The retaler of the plant s responsble for t beng legble.

2 ASSEMBLY
For all the assembly works n the engne room or n the elevator shaft, t should be made clear that:
The entrance nto the assembly area, resp. the executon of all works can be carred out only by skl-
led workers.
In partcular, the followng safety measures should be respected:
Fx the ant-fall protecton devce (workng platform, for safety of the persons);
- cover the hole n the floor;
- secure the assembly tools and other objects to avod falls;
- n case the works have to be executed n the elevator shaft, lock the doorways and attach the ap-
proprate warnng sgn.
2.1 ASSEMBLY OF THE OVERSPEED GOVERNOR
2.1.1 ASSEMBLY IN THE ENGINE ROOM
PREPARATION
The assembly of the overspeed governor occurs ether drectly on the floor n the engne room or on a support.
Floor and support must resst to a pressure of 25 kN
In the elevators n conformty to EN 81, the passng openngs of the rope should be kept as small as
possble and must be fitted wth safety rngs 50mm hgh.
For elevators n conformty to TRA, the same procedure s recommended.
Before the assembly takes place, t s necessary to fix an adequate safety rng on the floor.
If, after the assembly on the cement, a stone floor s lad down, ts heght should be consdered (fig. 1)

2.1.2 ASSEMBLY ON THE TOP OF THE ELEVATOR SHAFT
Safety measures, referrng to works on elevator plants, must be observed.
Mount the overspeed governor as shown n fig. 1 and 2 (or n an opposte way).
In case of assembly n the elevator shaft, the overspeed governor must be easly accessble from the
outsde (e.g. through an nspecton door for mantenance operatons).

2.2 ASSEMBLY OF THE ROPE OF THE OVERSPEED GOVERNOR/TENSION WEIGHT
WITH HORIZONTAL AND VERTICAL COUNTERWEIGHT
A techncally perfect operaton of the overspeed governor s only possble wth a correct assembly of the go-
vernor rope tself and of the tenson weght wth counterweght.
Whle determnng at whch heght the tenson weght wth counterweght has to be mounted, t must be made
clear that:
- n no case, the counterweght must touch the floor (fig. 1 and 2), otherwse, the functon of the overspeed
governor s put out of operaton;
- when the framework of the elevator car reaches ts lowest poston (by the compressed buffer), the lower
rope-anchor and the downward remanng rope-end must not meet the pulley of the tenson weght.
• Cut the overspeed governor rope sufficently and lay t down on the rope pulley of the tenson weght.
• Supply the first rope-end wth the rope-anchor (fig. 1 and 2) and attach t to the safety gear.
• Let the second pece of rope drop nsde the elevator shaft.

• Hold the counterweght, untl t s n an oblque pos-
ton (fig. 3).
• In the presence of a brake mechansm actng up-
wards, mount the second rope-end to the rope-an-
chor of the brake devce
or:
• Supply the second rope-end wth the rope-anchor
and attach t to the safety gear.
• Remove the support n order to stretch the rope.
If the assembly has been properly carred
out, the counterweght should take a slghty
upward angled poston (fig. 3).

2.3 ELECTRIC INSTALLATION OF THE SAFETY SWITCHES
All the works concernng the electrcal equpment should only be carred out by specalzed electr-
cans, sklled workers.
Before begnnng operatons, turn off the power of all the parts of the plant.
When layng the connecton cables, take care that:
• unpolar cables have a double coatng
• the use and layng of the cables are carred out accordng to the EMV rules and regulatons.
The safety swtches dsconnect the safety crcut of the elevator plant.
The followng safety swtches must be connected:

3 SETTING UP OPERATIONS
3.1 OVERSPEED GOVERNOR
The safety swtch of the overspeed governor has already been set n the factory. Its poston s fixed wth sea-
lng-wax and t cannot be modfied.
The settng up of the safety swtch on the overspeed governor s not necessary.
3.2 TENSION WEIGHT WITH COUNTERWEIGHT (EN 81 and TRA)
Only n plants n conformty to EN 81:
a) wth tenson pulley wth horzontal counterweght:
• shft the mountng clamp of the tenson weght wth counterweght n such a way that the safety swtch does
not become operatve (fig. 1, pos. 1).
At the same tme take nto consderaton the stretchng of the rope!
• On the safety swtch, adjust the horzontal connectng poston on the slots (fig. 1, pos. 2).
• After the assembly, release the tenson rope and check the control functon by movng the tenson arm. Then
fix the poston wth sealng-wax or smlar.
• After the nserton, the trppng pn of the safety swtch must be reset by hand n the startng poston.
b) wth tenson pulley wth vertcal counterweght:
• Move the mountng plate of the safety swtch n the vertcal drecton (fig. 2 – pos. 1) n such a way that the
swtch does not actvate.
• On the swtch, adjust the horzontal connectng poston on the slots (fig.2 – Pos. 2).
• After the assembly, release the overspeed governor rope and check the control functon by movng the coun-
terweght slowly downwards on the gude ral and payng close attenton. Then fix the poston wth sealng
wax or smlar.
• Followng the nserton, the trppng pn of the safety swtch must be reset n the startng poston.

4 OPERATION TESTING
Although qualty and operaton of each component are controlled by the factory at the delvery, before sale,
eventually, before the final test of the plant, an operaton testng should be carred out.
TEST RUN AFTER THE ASSEMBLY
Clean the gudes before the first test run takes place.
Before the begnnng of the run, leave the elevator shaft free from persons and objects.
Before the general test takes place, t s necessary to slowly run through the whole area of acton (wth nspec-
ton control devce). After that, verfy the dstance to be sufficent for all fastenng parts (partcularly n the fixng
area of the gudes and of the governor rope).
If possble before that, locate and remove screw projectons and other dangerous narrow ponts.
Subsequently, a statc functon test has to be carred out:
• operate by hand the overspeed governor: press down the rocker lever;
• drve the elevator cars lowly downwards.
The overspeed governor must release the safety gear.
The safety swtch must release and swtch off the safety crcut of the elevator plant.
Wth a slow movement upwards and/or downwards, place the overspeed governor and the satety gear back-
wards.
CONTROL OF ALL OPERATIONS
Subsequently, the release s to be controlled at a nomnal speed, as well as the relatve safety devces.
The control of the release s to be carred out as a dynamc functon test, wth or wthout rated load of the ele-
vator car.
Durng test runs, no-one must stay n the elevator car.
Lay down the governor rope nto the test groove and drve the elevator car at nomnal speed downwards/up-
wards.
Alternatvely, the overspeed governor can be operated also by hand, by pressng the rocker lever down.
The safety swtch must release and swtch off the safety crcut of the elevator plant.
Wth a slow movement downwards/upwards, brng the overspeed governor and the brake devce (the safety
gear) back agan.
CONTROL OF THE SAFETY DEVICE FOR ROPE TENSION
The safety swtch on the tenson weght wlh counterweght s controlled by removng the rope of the overspeed
governor from the rope pulley.
When the control s finshed, the release pn of the safety swtch must be reset by hand.

5 MAINTENANCE, CONTROL AND REPAIR
5.1 MAINTENANCE AND CONTROL
Generally, the overspeed governor and respectve tenson weght wth counterweght do not need any mante-
nance.
The whole plant has been conceved n such a way that, wth proper use wthout damages, there s no need for
mportant mantenance nterventons.
Accordng to the frequency of use, controls of the plant should be carred out perodcally.
After substantal changes or after an accdent, t s necessary to carry out a control of the plant (see
EN 81-2, annex E2).
Ths s necessary especally when safety devces are changed.
Changes, damages or other rregulartes must be notfied and, f necessary, repared wthn the lmts of the al-
lowed feasblty.
Perodcal controls ncrease, not only the safety, but also the trouble-free and long-lfe operaton of
the plant!
Partcularly recommended are controls and mantenance operatons before the operatng tests foreseen by the
law take place.
Please contact your suppler f there are any doubts regardng the operaton efficency of the components of
the plant.
MAINTENANCE AND CONTROL SCHEDULE
• Check every 6 (sx) months the operaton efficency of the overspeed governor.
• Check the damage or the dstortons of the overspeed governor and respectve structural elements.
• Check the wear of the undercut grooves of the overspeed governor and the grooves of the tenson pulley.
Danger of tear to the rope! When the governor rope runs n an rregular way, that s to say when the
