• Avoid contamination caused by abrasive media, reduce contamination by cleaning
on a regular basis.
9.1.3
Loading the workpiece pallet
The modular units are designed and tested under the assumption that the workpiece
pallets will not all have the same weight during one cycle on one conveyor section.
Workpiece pallets (WT) are both loaded and unloaded.
Signifi cantly different weights may require special measures to avoid malfunctions.
This applies to:
• The permitted accumulation length before stop gates.
• Damper functionality.
• Dampened stop gates.
9.1.4 Environmental
factors
• Our products are resistant to many media that are commonly found in manufacturing,
such as water, mineral oil, grease and detergents. Contact your Rexroth representative
if you have any doubts about resistance to specifi c chemicals, such as test oil,
doped oils, aggressive cleaning agents, solvents or brake fl uid.
• Avoid prolonged contact with highly reactive acidic or alkaline materials.
• Contamination can greatly increase wear – specifi cally from abrasive media from
the surrounding area, such as sand and silicates, e.g. from construction as well
as machining processes in the transfer system (e.g. welding beads, pumice dust,
glass shards, chips, waste parts, etc.). Maintenance intervals should be
signifi cantly shortened under these circumstances.
• Resistance to media and contamination does not mean that functional safety is
guaranteed in every case.
– Liquids that thicken as they evaporate and become highly viscous or adhesive
(sticky) can lead to malfunctions.
– If they get carried onto systems with rollers, media which have lubricating properties
can lead to a reduction in the drive power that is transmitted via friction.
In such instances, special care must be taken when planning the system,
and the maintenance intervals must be correspondingly shortened.
10 Maintenance and repair
WARNING
High electrical voltage!
Risk of severe injury or death from electric shock.
Disconnect the relevant system component before performing any maintenance
or repair work.
Secure the system against being unintentionally switched on again.
High pneumatic pressure!
Risk of severe injury or death.
Switch off the compressed air supply to the relevant system component before
performing any maintenance or repair work.
Secure the system against being unintentionally switched on again.
