Wiring check
After completion of wiring, it is necessary to check:
-
Connecting cables for damage.
-
Cables for pull relief.
-
Correct connection of cables to terminals.
-
Whether the supply voltage corresponds with the nameplate data.
Putting into operation
Prior to connection to power supply, check the device installation accuracy in accordance
with “Installation in pipeline“ and “Wiring” chapters.
Do not power up the meter during installation before the system is filled with the measured
medium and power off the meter before the system is discharged. After the meter is powered
up, the green LED on the top cover next to the M12 connector is lit, confirming the supply
voltage on the control PCB and stabilization of parameters of the meter takes place afterwards
(approx. 5 sec). After that period of time, the meter starts measuring.
Meter status:
It is continuously displayed by two indicator LEDs located in the evaluation unit top cover.
The meter status indicated by the LEDs can be as follows:
LED1
LED2

Flow direction:
The arrow indicates the direction liquid flow inside the sensor and thus the correct
orientation of the meter's sensor for installation in piping.
