1.8 Inputs/Outputs
The Uf 841 provides the following options:
•
Up to 4 input/output single modules (or 2 double modules), made by Ultraflux in the factory only
(in accordance with the customer order).
•
Insulation of all the inputs and outputs. There is therefore no requirement for additional insulation
for the external equipment connected to them.
The Uf 841 allows 6 types of inputs/outputs to be used (maximum values in brackets):
•
Single module 1 active 4-20 mA insulated analogue output: current from 0 to 24 mA (24 V
maximum),
•
Single module 2 passive 4-20 mA insulated analogue inputs: 0 to 24 mA (50 mA maximum),
•
Single module 2 passive 0-10 V insulated analogue inputs (15 V maximum),
•
Single module 2 on/off outputs that can be used as frequency outputs (50 V - 10 mA maximum),
•
Single module 2 on/off inputs (5 V maximum),
•
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 probes (inputs) on the 4-20 mA loop must be powered from an external power supply.
1.9 Ultrasound chords
The Uf 841 enables the control of a maximum of 4 ultrasonic chords, or 8 probes. 8 cable glands are
provided to pass the probe cables through.
In principle, only ultrasonic probes supplied by Ultraflux may by used with the Uf 841. Ultraflux accepts no
responsibility for damage or incidents which may occur following a failure to respect these instructions. It is
however possible to use other makes of probe after consulting Ultraflux.
1.10 Navigation keys
•
The "Fn" (Function) key is used to go from one menu to another. This is used in particular to enter
the different "configuration" menus. The
t
and
u
keys are used to browse through the menus of
this mode.
•
Holding down the Fn key, or allowing approximately 1 minute to pass without using the keypad,
returns you to "measurement" mode.
•
Within any one menu, the
t
and
u
keys are used to change page. These keys may also have a
contextual function. If this is the case, a reminder of this function will be provided at the bottom of
the screen page, such as the choice of screen in measurement mode, which is displayed by default.
•
After powering on the Uf 841, the screen displays the page that has been selected as priority. To
choose this default screen, position yourself on it and define it by default by pressing on the "B"
key.
