Output behaviour

7.1

SWITCHING OUPUTS

The EDS 3000 has either 1 or 2 switch outputs. The following switch behaviour can be set
in the basic settings:

7.1.1 Set to switch point (SP)

A switch point and a reverse switch point can be set for each switching output. The output
will switch when the set switch point is reached and switch back when the pressure drops
below the reverse switch point.
Example for switching point 1 (normally closed and normally open function):
Normally open function
Normally closed function
Abbreviations:
"SP1", "SP2" = switch point 1 / switch point 2
"RP1", "RP2" = reverse switch point 1 / reverse switch point 2
"HNO", = Normally open when hysteresis function is active
"HNC" = Normally closed when hysteresis function is active

7.1.2 Setting to window function (Fno / Fnc)

The window function allows you to monitor a range. An upper and a lower switch value can
be entered for each switch output. These values determine the range.
The output then switches when the pressure enters this range.
When the pressure leaves this range, i.e. when it reaches the reverse switch point, the
output switches back. The lower reverse switch value is just below the lower switch value.
The upper reverse switch value is just above the upper switch value. The range between
the switch value and the reverse switch value forms a safety margin which prevents
unwanted transients from being triggered (such as those triggered by the pulsations of a
pump).
