1.3 Terms and Identification of Notices
Important notices in Chapter 4 (Assembly), Chapter 5 (Operation) and Chapter 6 (Disassembly /
Exchange) referring to technical security as well as to industrial safety are particularly
highlighted by the following signal words:
ÎDanger!
Refers to processes and operation procedures which are to be thoroughly
observed in order to exclude a hazard to persons.
ÎAttention!
Refers to safety measures which must absolutely be followed in order to
avoid brake failures .
ÎStop!
Refers to instructions that have to be particularly observed when carrying
out the work described.
In order to simplify the text of these operating and assembly instructions, certain longer and
complicated terms are replaced by shorter ones which will have the following meanings in the
scope of these instructions:
Instructions
= Operating and assembly instruction
Working brake
= Brake which implements friction work in regular operation, i.e. performs a
braking function
Brake
= Spring-applied brake = electromagnetically released spring-applied brake
Data sheet = Technical data sheet
Holding brake = Brake which does not perform friction work in regular operation but merely
holds the load in position. In case of an emergency, however, it may also perform a braking
function.
End plate = Motor end plate = end plate of an electric motor
Dimension sheet = Dimension drawing
PRECIMA = M/s. PRECIMA = PRECIMA Magnettechnik GmbH, Bückeburg
Shaft = Motor shaft = shaft of an electric motor
In the scope of these operating and assembly instructions, the spring-applied brake is
considered to be a machine element to be connected to an electric motor since this
combination represents the most frequently used variant.
Accordingly, certain designations
refer to said fact (motor shaft, motor end plate Î see above). However, this is no general
limitation of the validity of these instructions to such combinations - just as there is no
comparable limitation to the application of the spring-applied brake at all.
