NT UF 811 CP GB (e) / June 2015
1.7 Inputs/Outputs
The Uf 811 provides the following options:
 Integration of up to 4 single modules (or 2 double modules) of inputs/outputs.
 Connection of the inputs/outputs to the equipment directly via connectors, without the need for
any intervention inside the flow meter.
The modules are factory-installed by Ultraflux.
The Uf 811 allows six types of inputs/outputs to be used:
 Single module 1 active 4-20 mA insulated analogue output: current from 0 to 24 mA,
 Single module 2 passive 4-20 mA insulated analogue inputs: current from 0 to 24 mA,
 Single module 2 passive 0-10 V insulated analogue inputs: voltage from 0 to 15 V,
 Single module 2 on/off outputs (50 V - 10 mA) which can be used as frequency outputs,
 Single module 2 on/off inputs (5 V),
 Double module 2 PT100/PT1000 temperature inputs; 2- 3- or 4-wire.
Notes :

Please refer to the descriptive sheet for each module for more details.
 The sensors on the 4-20 mA loop may by powered from an external power supply.
1.8 Ultrasound chords
The Uf 811 can manage 2 ultrasound chords. Each connector corresponds to one ultrasonic chord, in other
words two probes. As standard, it is therefore necessary to use the Y-cable provided with the flow meter in
order to separate the two probe cables.
1.9 Navigation keys

Changing from one type of screen to another is done by using the "Fn" (for Function) key. This "Fn"
key in particular is used to enter "configuration" mode. The

and

keys allow the user to browse
through the menus for this mode.
 A long press on the Fn key, or allowing approximately 1 minute to pass without using the keypad,
returns you to "measurement" mode.

Within a menu, the

and

keys are used to change page. These keys may also have a contextual
function which in this case will be shown at the bottom of the screen page, such as that of selecting
the measurement mode screen which is displayed by default.
 After powering on the Uf 811, the screen displays the page which has been selected as priority. To
choose this "default" screen, select and validate it by pressing the "B" key in measurement mode.

To scroll through the measurement screens, use the

and

keys.
 To access the other menus, press the "Fn" key, then successively press the

key, or browse using
the

and

keys.
