Explanation and setting options
Standard measurement parameter for evaluation by OUT1:
FLOW or TEMP
Output function for OUT1:
▪ Flow: Hno, Hnc, Fno, Fnc, ImP
Temperature: Hno, Hnc, Fno, Fnc
▪
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
Imp = Consumption quantity monitoring (totaliser function)
OFF = Output OFF (high impedance)
Switching point for OUT1
Reset point for OUT1
Upper limit value for OUT1
Lower limit value for OUT1
Pulse value = flow quantity at which 1 pulse is delivered.
Configuration of OUT1 for consumption quantity monitoring:
YES (pulse signal), no (switching signal).
Switching delay on OUT1.
Reset delay on OUT1.
Response of OUT1 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
FOU1 is not available if ou1 = ImP was selected.
