8 Settings
The following setting parameters can be read using the PC software UCOM and are also alterable.
The customer-specific settings are shown on the parameter print-out, which is included in the
documents.
Please find operation instructions PC software UCOM in document U385.
9 Performance Test
sensor not connected
(pay attention to 6.2.1 Power supply and 6.2.3 Analog output)
after connecting the supply voltage the green and yellow LED light up.
The analog output sends a value between 3.4 mA and 3.6 mA with output current or between –0.3 V and
–0.2 V with output voltage.
10 Initial Operation
sensor connected
(pay attention to 6.2.1 Power supply, 6.2.2 Sensor input and 6.2.3 Analog output)
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 sends a value of 4 mA with output
current (or 12 mA depending on configuration with FAR sensors) or with output voltage a value of 0 V (or
5 V depending on configuration with FAR sensors, see under 7 Functional Description)
Flow at sensor: the green LED flashes, the analog output sends an analog value deviating from the zero
flow conditions (see above).
11 Operation
(Pay attention to 5.3 Operating Conditions and 5.6 Electrical Data)
12 Shut-down, Dismantling
Before disconnecting the cable, please ensure that the supply voltage is switched off.
