Replacing an exchange module

Depending on the application, exchange modules can wear down and should be replaced
to ensure a consistent level of activation. Proceed as described in Point 7.4.
With reference to the exchange modules, the availability of the system is described in terms
of Mean Time to Failure (MTTF).
Due to the different integration situations and processes, these values can only be taken as
approximate guide values that need to be defined under laboratory conditions. Due to the
mode of operation and the device, the device may be subjected to certain kinds of process
feedback which can affect the load capacity of the exchange modules.
Attention – System availability
To keep downtime on the system to a minimum, we advise keeping a certain
number of exchange modules in stock.
For the Standard module, the MTTF is 3,000 operating hours. For the Nearfield module, the
MTTF is 2,000 operating hours.
Please refer to the separate data sheets and/or manuals for these modules to obtain values
for other modules.
You can source replacement modules directly from relyon plasma GmbH. To optimise our
exchange modules, we evaluate the ones that are returned to us. Please contact us and
return your defective or replaced exchange modules to us for analysis.
Attention – Damage to device!
Never touch the piezo element on the front side of the device with sharp-edged objects.
This component may be damaged by improper handling.
