Operating instructions 10/2017
9.3
Incorrect use
Experience has shown that the following faults can result in incorrect use of the ARPEX coupling. In
addition to observing the other instructions in this manual, care must therefore be taken to avoid these
faults.
Directive 2014/34/EU requires the manufacturer and user to exercise especial care.
WARNING
Risk of serious injury through flying fragments
Risk of serious injury through flying fragments and/or risk of damage to the coupling.
The coupling is designed only for the application specified in the order. Other operating conditions are
regarded as incorrect and must be contractually agreed. For any damage resulting therefrom only the
user or operator of the machine or plant is responsible.
DANGER
Danger of explosion
Risk of explosion when operating in potentially explosive areas through damage.
Damaged coupling modules and coupling parts are potential explosion hazards.
Use only undamaged coupling components. Operating the coupling with damaged coupling parts is not
permitted in potentially explosive environments in accordance with Directive 2014/34/EU.
9.3.1
Possible faults when selecting the coupling and/or coupling size
─
Important information for describing the drive and the environment are not communicated.
─
System torque too high.
─
System speed too high.
─
Application factor not correctly selected.
─
Chemically aggressive environment is not being taken into consideration.
─
The temperature in the direct vicinity of the coupling is beyond the permissible range.
─
The transmission capacity of the shafthub connection is not appropriate to the operating conditions.
─
Fitting and/or operational misalignment values of the shaft ends of the machines to be coupled are too
high.
