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).
