4.5 Application Example 5
4.5.1 Description
• In normal operation the internal SED2 PID loop is working and managing the
pressure e.g. in a stairway. This application is equivalent to application 4 in the
Commissioning Guide CM1G5192 just enhanced with the ESM function.
• In case of fire the fire control panel signals this to the SED2, it is going in the
ESM mode and the internal PID loop keeps on working.
