8 Operation and use
NOTICE!
Property damage due to high temperatures.
Extreme pneumatic conditions (high cycle rate with high pressure amplitude) can
heat the product above 80C.
• Select the operating conditions (in particular the ambient temperature, pres
sure amplitude, cycle rate, current consumption) such that the product does
not heat up above 80°C.
• Switch on the operating voltage.
Ä
The SDE5 is in RUN mode (basic status).
9 Service
1. Turn off energy source and compressed air.
2. Clean sensor with nonabrasive cleaning agents.
