UFS8000 Components 34
6.8. Pressure meter
The pressure meters equipped with a 0(4)-20mA output can be connected to the control panel.
It is possible to specify thresholds for the upper and lower limits, both with a programmable time delay.
It is also possible to specify whether the installation should be shut down in case of either positive or
negative crossing of the specified values.
If the thresholds are activated, it is possible to send an alarm message when, for instance, the upper
threshold is exceeded (this can be either through a relay or with an e-mail (only possible with
UFS8x1x-xxxx)).
The properties of the pressure meters are only visible if the control panel is equipped with prints with
0-20mA inputs (ca-fl-pr-3an).
