2 Function and application
The SDE3 has been designed for monitoring changes in pressure in the
compressed air system or terminals. Variants for relative pressure measurement
and differential pressure measurement are available:

3 Requirements for product use
Warning
Depending on the functions of the machine/system, the manipulation of signal
statuses can cause serious injury to people or material damage.
Note that if the switching characteristics of the switching outputs is modified
in EDIT mode, the new status becomes effective immediately.
Enable the password protection option (security code) to prevent accidental
alteration by an unauthorised third party (è Chapter 5.3 section Set security
code).
Warning
The usage of the SDE3 in combination with impermissible media can lead to
personal injury or material damage.
Use the SDE3 only with compressed air
Observe the specified air quality class (è Chapter 11 Technical data).
