Hints and Instructions Regarding the Use in
Hazardous Areas
5.7 Breakdowns, Causes and Elimination
The below-mentioned errors can lead to an incorrect use of the
POLY
coupling. In addition to the stipulations in
these operating and mounting instructions please make sure to avoid these errors.
The errors listed can only be clues to search for the errors. When searching for the error the adjacent
components must be generally included.
Due to incorrect use the coupling can become a source of ignition.
EC Standard 94/9/EC requires a special care from the manufacturer and the user.
General errors incorrect use
•
Important data for the coupling selection was not forwarded.
•
The calculation of the shaft/hub connection was not considered.
•
Coupling parts with damage occurred during transport are assembled.
•
If the heated hubs are assembled, the permissible temperature is exceeded.
•
The fits of the parts to be assembled are not coordinated with each other.
•
Tightening torques are below/exceeded.
•
Components are exchanged by mistake/put together incorrectly.
•
A wrong or no elastomer elements is inserted into the coupling.
•
No original KTR parts (purchased parts) are used.
•
Old elastomer elements/already worn out elastomer elements or superposed elastomer elements
are used.
•
The coupling used/the coupling protection used is not suitable for the operation in hazardous
areas and does not correspond to EC Standard 94/9/EC, respectively.
•
Maintenance intervals are not observed.

danger of ignition due
to sparking
1) put the unit out of operation
2) eliminate the reason for the
misalignment (e. g. loose foundation
bolts, break of the engine fixing, heat
expansion of unit components, change
of the assembly dimension E of the
coupling)
3) check coupling parts and exchange
damaged coupling parts
4) checking of wear see under point
Control

of coupling slip
danger of ignition due
to hot surfaces
1) put the unit out of operation
2) disassemble the coupling and remove
rests of the elastomer elements
3) check coupling parts and exchange
damaged coupling parts
4) insert elastomer elements, assemble
coupling parts
5) check alignment, correct if necessary
