Hysteresis function
The PSA10 has 2 switch outputs. The following settings can be made under the basic settings:
Example for switch point 1 (normally closed and normally open function):
Switch point setting (SP)
One switch point and one switch-back point can
be set for each switching output.
The particular output will switch when the set
switch point is reached and switch back when the
pressure drops below the switch-back point.
Abbreviations:
"SP1", "SP2" = Switch point 1, switch point 2
"RP1", "RP2" = switch back point 1, switch back point 2
"HNO",
= normally open with hysteresis function
"HNC"
= normally closed with hysteresis function
NOTE:
It is only possible to set the switch point (SP) if it is higher than the respective switch-back point
(RP). In the case of low SPs we recommend setting the RP first.
