8.4 Replacing the Entire Detector
To replace the detector, proceed as follows:
1. Document all software parameters of the installed detector
2. Take the old detector out of operation as described in chapter “Decommis-
sioning”.
3. Install the new detector as described in chapter “Installation”.
4. Perform the electrical installation as described in chapter “Electric Installa-
tion”.
5. Transfer the software parameters of the old detector to the new one.
If the detector has been previously used, please note that detectors that were
used in non-hazardous areas must no longer be used in a hazardous area!
Intrinsically safe detectors whose intrinsically safe signals were connected to
non-intrinsically safe circuits must not be connected to intrinsically safe circuits.
