Operating instructions 01/2019
9.
Faults, causes and remedy
Observe the instructions in section 3, "Safety instructions"!
9.1
General
The following irregularities can serve as a guide for fault tracing.
Where the system is a complex one, all component units must be included when tracing faults.
The coupling must run with little noise and vibration in all operating phases. Irregular behaviour must be
treated as a fault requiring immediate remedy.
Flender will not be bound by the terms of the guarantee or warranty or otherwise be
responsible in cases of improper use of the coupling, modifications on the coupling
carried out without the agreement of Flender, or use of spare parts not supplied by
Flender.
When remedying faults and malfunctions, the coupling must always be taken out of
service. Secure the drive unit to prevent it from being started up unintentionally.
A notice should be attached to the ON switch stating clearly that work is in progress.
We also refer to the relevant accident prevention regulations at the place of
installation.

Possible faults
Table 8:
Faults, causes and remedy
Faults
Causes
Remedy
Sudden changes in the noise
level and/or sudden
vibrations.
Change in alignment.
Stop the installation.
If necessary, rectify any cause of the
changes in alignment (e.g. by fastening loose
foundation bolts).
Check wear; procedure as described in
section 10.
Plate breakage, torque
transmission via close-fitting
bolts / conical bolting
Stop the installation.
Demount coupling and remove remains of
pack.
Check and replace damaged coupling parts.
Check and, if necessary, adjust alignment
(see section 6).
Operating the coupling with broken ARPEX plate packs is not permitted under
Directive 2014/34/EU. A correct torque transmission is no longer guaranteed in such
case. Perform a visual check of the ARPEX coupling as described in section 10.
A damaged coupling becomes an explosion hazard. Operating the coupling with
damaged coupling parts is not permitted in potentially explosive environments in
accordance with Directive 2014/34/EU.
