• The pressure sensor detects the
system pressure (P1)
,
• shows the current system pressure on its
display
• and generates
2 output signals
according to the set output con-
figuration.
• In addition an
analogue signal (P2)
which can be configured can
be supplied. It has influence on the switch points preset in the basic
settings or on the preset window and on the pressure values dis-
played (display P2 or P1-P2).

IEP2: pressure value to which the
final value of the analogue
signal set in IHP2 is to
correspond
