Avoid static and dynamic overpressure exceeding the given overload
pressure by taking appropriate measures�
The indicated bursting pressure must not be exceeded�
Even if the bursting pressure is exceeded only for a short time, the unit
may be destroyed� ATTENTION: Risk of injury!
Not suitable for use where the criteria for paragraph D10�1�2/74-03 of the 3A
standard 74-03 have to be met�
4 Function
• The unit displays the current system pressure�
• It generates output signals according to the operating mode and the parameter
setting�
• It moreover provides the process data via IO-Link�
• The unit is laid out for fully bidirectional communication� So, the following
options are possible:
-Remote display: reading and display of the current system pressure�
-Remote parameter setting: reading and changing the current parameter
setting�
