9 Performance Check
Sensor not connected
(Please pay attention to 6.2.2 Power supply and 6.2.5 Analog outputs)
After connecting the supply voltage the green and yellow LED light up.
The analog output provides a value between 3.4 mA and 3.6 mA with current output or between –0.3 V
and –0.2 V with voltage output.
10 Initial Operation
Sensor connected
(Please pay attention to 6.2.2 Power supply, 6.2.3 and 6.2.4 sensor inputs and 6.2.5 Analog outputs)
After connecting the supply voltage the green LED lights up and the yellow LED is off.
No flow at sensor: the green LED is permanently on; the analog output provides a value of 4 mA with
current output and 0 V with voltage output.
Flow at sensor: the green LED flashes; the analog output supplies an analog value deviating from the
zero flow conditions (see above).
11 Operation
(Please pay attention to 5.3 Operating Conditions and 5.5 Electrical Data)
12 Shut-down, Dismantling
Before disconnecting the cable, please ensure that the supply voltage is switched off before
disconnecting the cable.
13 Inspection
Check the LEDs, (see under 7 Functional Description, Self diagnosis)
