Hints and Instructions Regarding the Use in
Hazardous Areas
5.7 Breakdowns, Causes and Elimination
breakdowns causes
hints to danger for
hazardous areas
elimination
operating
parameters do not
correspond to the
performance of the
coupling
---
1) put the unit out of operation
2) check the operating parameters and
select a larger coupling (consider
installation space)
3) assemble new coupling size
4) check alignment
break of the
elastomer part /
toothing
mistake in service of
the unit
---
1) put the unit out of operation
2) disassemble the coupling and remove
remainders of the elastomer part
3) check coupling parts and replace
damaged coupling parts
4) insert elastomer part, assemble
coupling parts
5) instruct and train the service staff
drive vibrations
danger of ignition due
to hot surfaces
1) put the unit out of operation
2) disassemble the coupling and remove
remainders of the elastomer part
3) check coupling parts and replace
damaged coupling parts
4) insert elastomer part, assemble
coupling parts
5) check alignment, correct if necessary
6) find out the reason for the vibrations
ambient / contact
temperatures which
are too high for the
elastomer part, max.
permissible
e. g. T4 =
-30 °C / +100 °C
danger of ignition due
to hot surfaces
1) put the unit out of operation
2) disassemble the coupling and remove
remainders of the elastomer part
3) check coupling parts and replace
damaged coupling parts
4) insert elastomer part, assemble
coupling parts
5) check alignment, correct if necessary
6) check and regulate ambient / contact
temperature
excessive wear at
the elastomer part /
toothing
e. g. contact with
aggressive liquids /
oils, ozone-
influence, too high
ambient
temperatures etc.
effecting a physical
change of the
elastomer part
---
1) put the unit out of operation
2) disassemble the coupling and remove
remainders of the elastomer part
3) check coupling parts and replace
damaged coupling parts
4) insert elastomer part, assemble
coupling parts
5) check alignment, correct if necessary
6) make sure that further physical changes
of the elastomer part are excluded
If you operate with a worn elastomer part (see item 5.2) a proper operation meeting the explosion
protection requirements and acc. to Standard 94/9/EC is not ensured.
