Commissioning and measuring operation
Before switching on the IVMZ.2 for the first time, please follow the instructions in the
following section.
6.1 Commissioning
Check that
the IVMZ.2 has been installed correctly and that all screw connections are
sealed.
the electrical wiring has been connected properly.
the measuring system is vented by flushing.
6.2 Switching on and off
The IVMZ.2 has no switch and cannot be switched on or off on its own. Switching on and
off is carried out by the applied supply voltage.
Switch on the supply voltage.
The green LED lights up. The IVMZ.2 is ready and goes into measuring
mode.
6.3 Measuring operation
In the measuring mode, the green LED flashes proportional to the measured flow.
For the human eye, the flashing is no longer visible from a frequency of ~30...40 Hz.
The green LED then seems to light up permanently.
IVMZ.2 with frequency output:
The IVMZ.2 provides according to the
version a flow proportional NPN, PNP or
Push-Pull square wave signal.
The frequency of the pulse output changes
according to the flow ( Fig.).
IVMZ.2 with analogue output:
According to the configuration of the IVMZ.2, the analogue output provides a voltage or cur-
rent signal.
This signal is proportional to the measured flow. You will find the scaling of the analogue out-
put on the type plate.
