Remote version:
– Switch off the power supply and check the wiring
– If necessary, reverse the connections at terminals 41 and 42
2.
Change the setting in the INSTALLATION DIRECTION SENSOR function accordingly
Measured value reading fluctuates even
though flow is steady.
1.

3.
Increase the following values:
– Analog Input function block 1 to 2
→
RISING TIME (PV_FTIME)
– BASIC FUNCTIONS
