9 Operation
CAUTION
Hot electric motor surfaces during operation!
Risk of burns from touching hot surfaces above 65 °C.
Install appropriate guards.
Let the unit cool down at least 30 minutes before performing maintenance and/
or repair tasks.
9.1 Notes regarding operation
9.1.1 Wear
• Individual components are subject to unavoidable wear by their very nature.
Structural measures and the selection of materials are used to achieve functional
reliability over the full service life. However, wear is also dependent on the
operating, maintenance and ambient conditions at the place of use (resistance,
contamination).
• The overloading of conveyor sections can lead to failure of the conveyor medium
and the premature failure of motors and transmissions.
• If pneumatically activated components are overloaded, it is not possible to
guarantee their function.
9.1.2
Measures to reduce wear
The following commonsense measures will reduce wear:
• Switch off the conveyor section during system shutdowns, for example, during
breaks, at night, and on weekends.
• Do not select a higher speed for the conveyor section than that required for the
corresponding function.
• Avoid contamination due to abrasive media, reduce contamination by cleaning on a
regular basis.
9.1.3
Loading the workpiece pallet
The components are designed and tested under the assumption that the workpiece
pallets will not all have the same weight during one cycle on one line section. Pallet
assemblies both loaded and unloaded.
Signifi cantly different weights may require special measures to avoid malfunctions.
This applies to:
• The permitted congestion length before stop gates.
• Damper functionality.
• Dampened stop gates.
