Explanation and setting options
Standard measurement parameter for evaluation by OUT2:
FLOW or TEMP
Output function for OUT1:
▪ Flow: Hno, Hnc, Fno, Fnc, I, ImP
Temperature: Hno, Hnc, Fno, Fnc, I
▪
Hno = Switching signal with hysteresis function normally open
Hnc = Switching signal with hysteresis function normally closed
Fno = Switching signal with window function normally open
Fnc = Switching signal with window function normally closed
I = Analog signal 4 to 20 mA
In.D = Input for external counter reset signal
Imp = Consumption quantity monitoring (totaliser function)
OFF = Output OFF (high impedance)
Analog starting point for OUT2
Analog end point for OUT2
Switching point for OUT2
Reset point for OUT2
Upper limit value for OUT2
Lower limit value for OUT2
Pulse value = flow quantity at which 1 pulse is delivered.
Configuration of OUT2 for consumption quantity monitoring:
YES (pulse signal), no (switching signal).
Switching delay on OUT1.
Reset delay on OUT1.
Response of OUT2 in the event of an internal error:
OU = output reacts as normal
On = output switches ON / analog signal goes to 21.5 mA
OFF = output switches OFF / analog signal goes to 3.5 mA
FOU2 is not available if ou2 = ImP was selected.
