6.2.4 Adjustable parameters
Switch point 1/2
Upper limit value at which the output changes its
switch status.
SP 2 is only active if
OU2 = Hno, Hnc, Fno or Fnc
(see below)
Return switch point 1/2
Lower limit value at which the output changes its
switch status.
rPx is always smaller than SPx. Values can only be
entered which are lower than SPx.
When the switch point is changed, the return switch
point changes with it (the interval between SPx and
rPx remains constant). If the interval is larger than the
new switch point, it is automatically reduced (rPx is
set to the minimum setting value). rP2 is only active if
OU2 = Hno, Hnc, Fno or Fnc . (See below)
Configuration for output 1
5 functions can be set:
•
Hno = Hysteresis function/normally open (NO
contact)
•
Hnc = Hysteresis function/normally closed (NC
contact)
•
Fno = Window function/normally open (NO con-
tact)
•
Fnc = Window function/normally closed (NC con-
tact)
Output signal for consumption quantity:
•
ImP = Pulse (value depends on the nominal
width, see electronic sensor assembly identifica-
tion plate)
Configuration for output 2
6 functions can be set:
Output signals for flow measurement:
•
Hno = Hysteresis function/normally open (NO
contact)
•
Hnc = Hysteresis function/normally closed (NC
contact)
•
Fno = Window function/normally open (NO con-
tact)
•
Fnc = Window function/normally closed (NC con-
tact)
•
I = Analog signal (4 - 20 mA)
Output signal for consumption quantity:
•
ImP = Pulse (value depends on the nominal
width, see electronic sensor assembly identifica-
tion plate)
Analog starting point
Measurement value at which 4 mA are output. ASP is
only active if
OU2 = I
Analog end point
Measurement value at which 20 mA are output.
Minimum distance between ASP and AEP = 25 % of
the measuring range final value. AEP is only active if
OU2 = I .
