8 Taking out of service
• Apply a voltage of 0V to the 'Plasma On' switch input.
• To reduce superfluous power consumption, after extended periods of downtime, it is
advisable to deactivate the 24V power supply.
9 Maintenance
9.1 Cleaning
• Only clean the outside of the device.
• Ensure that the device is disconnected from its power supply.
• Only clean the device with a cloth dampened in water. Do not use solvents to clean the
device.
• Do not clean or touch the piezo element.
9.2 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
device's mode of operation, the device may be subjected to certain kinds of process
feedback which can affect the load on 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 other modules to obtain values
for these 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.
