2. MAINTENANCE
2.1. Module Maintenance
The modules of the AirLINE Ex system are maintenance-free when operated in accordance with the
instructions in this operating manual.
2.2. Cleaning
DANGER!
Danger.of.explosion.caused.by.electrostatic.charge!
If there is a sudden discharge from electrostatically charged devices or persons, there is a danger of explosion in
the EX area.
• Clean the device surface of the solenoid valve by gently wiping it with a damp cloth only.
Clean the system with a damp, lint-free cloth only.
Solvents or alcohol are not suitable for cleaning. They may attack the plastic parts.
2.3. Diagnosis Function
2.3.1. Switching Cycle Counter
The current counter readings are stored in the modules at regular intervals where they are safe even in the event
of a power failure.
If the operating voltage is frequently switched off, it is possible that individual switching cycles are not
recorded in the remanent memory so that the stored number of switching cycles is slightly lower than the
actual number of switching cycles performed.
Details of this can be found in the chapter Configuration and Function of the Modules / Electronic
Modules and Commissioning / Initial Start-up.
