Adjustmentandcommissioning
Switching only occurs if one of the thresholds, high or low (functions "High" or "Low"), is exceeded for a duration
longer than this time delay.
PULSE: When the choice “Pulse” is selected in MODE function above, enter here the volume of fluid for which a
pulse must be transmitted on transistor output 1 or transistor output 2 respectively.
hysteresis operating
The output status changes when a threshold is reached:
• by increasing flow rate, the output status changes when the high threshold ("high") is reached.
• by decreasing flow rate, the output status changes when the low threshold ("low") is reached.

pulse operating (choice "pulse")
This function is used to generate a pulse on the transistor output each time a predetermined volume of fluid passes.
Enter the desired fluid volume and, if necessary, modify the volume units/pulse in the “PULSE” function in the “Output.

• A “Warning” event is emitted and the message “W:TRnPu too big” is displayed when the volume
entered multiplied by the K factor of the device > 1000000.
• A “Warning” event is emitted and the message “W:TRnPu 1:1:set” is displayed when the volume
entered multiplied by the K factor of the device < 1. In this case, the pulse frequency is forced to the
value of the input frequency.
