Configuring the digital input DI1 to switch from a measured value to a replacement value
NOTE!
The replacement value is ignored if the checking function for proper output response is active (
see
chapter 8.7.3 "Checking proper response of the outputs", page 70).
NOTE!
The units of the displayed values and the values to be entered manually correspond to the values se-
lected in chapter 8.6.2 "Choosing the flow rate unit, the number of decimals, and the counter display
unit", page 38.
This function enables a replacement value specified by the user to be emitted instead of the mea-
sured value.
When the digital input is activated:
•
The device status LED flashes.
•
The signal transmitted at the 4 to 20 mA output is set to the replacement value.
•
The displayed flow rate is set to the replacement value.
•
Each transistor or relay output adopts the status depending on the replacement value.
•
The counters do not increment any more.
•
The replacement flow rate is active until the digital input switches again.
