6.1 Switching
Outputs
The EDS 8000 has 2 switching outputs. The following settings can be made under the
basic settings:
6.1.1 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.
Example for switch point 1 (normally closed and normally open function):
Abbreviations:
"SP1", "SP2" = switch point 1 / switch point 2
"RP1", "RP2" = switch-back point 1 / switch-back point 2
"HNO",
= normally open when hysteresis function is active
"HNC"
= normally closed when hysteresis function is active
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.
6.1.2 Window function setting (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 relevant output will then switch when the pressure enters this range.
When the pressure leaves this range, i.e. when the switch-back point has been reached,
the output switches back. The lower switch-back value is just below the lower switch
value. The upper switch-back value is just above the upper switch value. The range
between the switch value and the switch-back value forms a safety margin which
prevents unwanted switching operations from being triggered (such as those triggered by
the pulsations of a pump).
