Analogue Output (Dgt4 An, Dgtq An And Dgtp An Version) - Vetek DGT Technical Manual

7. ANALOGUE OUTPUT (DGT4 AN, DGTQ AN and DGTP AN version)

In all the functioning modes, through an optional interface, it is possible to use an analogue output configurable at 0 –
10V, 0 – 20 mA or 4 – 20 mA. The voltage and the output current from the interface are proportional to the gross
weight or net weight present on the scale. In regards to the electrical connection scheme, refer to the section 11
"ELECTRICAL SCHEMES".
Note: The analogue output is updated every 50ms and takes on the value corresponding to the weight converted in
that instant; therefore if the filter is slowed on the weight, the analogue output also slows down.
For configuring the parameters, one should enter the setup environment and enter in the SEtuP >> ConFiG >>
Anout step.
SEtuP
ChAn
By entering this step, one selects the channel to be configured (from 1 to 4).
NOTE: The parameter is not displayed if one has set "dEP.CH" in the tYPE parameter or in case of one channel
application, step SEtuP >> ConFiG >> nChAn.
ModE
By entering this step one selects the tyep of analogue output:
Ao no = analogue output disabled.
Ao G = analogue output on gross weight.
Ao n = analogue output on net weight.
Once the functioning mode is confirmed, one sets the values of the analogue output; in other words, the
digital/analogue converter values are entered (between 0 and 65535) to which corresponds a certain output value in
voltage or in current.
In this configuration the instrument keys take on the following meanings (functions):
ZERO It decreases the selected digit (blinking).
TARE It increases the selected digit (blinking)
MODE It selects the digit (blinking) from left to right.
PRINT
C It allows to quickly zero the present value.
NOTE: The functioning mode is just one for all the configured channels.
AoMAX
By entering this step, one sets the maximum value of the analogue output, in other words:
− with functioning on the positive weight
condition.
− with functioning on the negative weight
This value can be anywhere between 0 and 65535 (values of the digital/analogue converter); if a higher digit is
An.out
By pressing once after have a value has been entered, it enables the corresponding output
analogue value, (allowing the check) but remains still inside the step in case of a new
modification. By pressing a second time (on the same entered value), it confirms and exits
the step.
the value corresponding tohe full scale capacity and in the overload
the value corresponding to the under load condition.
