19.2 Maintenance
19.2.1 Maintaining modules
The AirLINE Ex system modules do not require maintenance if used in accordance with these operating
instructions.
If coarse residue occurs in the compressed air supply lines, it may accumulate in the filter of the connection
segments (only REV.2). If necessary, uninstall the filter as described in chapter “16.10.1 Connection seg-
ments” on page 73 , clean it and reinstall it.
19.2.2 Cleaning
Danger
Risk of explosion due to electrostatic charge
If there is a sudden discharge of electrostatically charged devices or persons, there is a risk of explosion
in the potentially explosive atmosphere.
▶
Clean the device surface by gently wiping it with a damp cloth only.
→ Only use a damp, lint-free cloth to clean the system.
Detergents or alcohol are not suitable for cleaning. They can damage plastic parts.
19.2.3 Diagnostics function
switching cycle counter
The current counter values are saved in the electronic modules in an outage-proof manner at regular
intervals.
In the event of frequent operating voltage failures, it may happen that individual switching cycles are
not documented in the remanent storage, thereby causing the saved number of switching cycles to
be slightly lower than the number of actual switching cycles.
Details can be found in chapters “12.1” on page 45 and “17” on page 83 .
