DFW series indicators DFW_03_12.07_EN_U

- (if listen mode = “no”) one is asked to enter the SLAVE keyboard type: “kb.dFW” (for DFW type instruments), “kb.dFkr“
(for DFWKR type instruments), “kb.dGt” (for DGT type instruments), “kb.CPWE” (for CPWE/3590E type instruments),
“kb.3590” (for 3590 type instruments).
- in the DFWPM10USB model, if the extended protocol (“EXtEnd”) has been selected, one is asked to disable the list of
weighs or to enable it in one of the two available functioning modes.
- if the list of weights is enabled, must be set the close list parameter (“CLoS.LS”).
- if two or more slaves are set, the menu “SuM.PAr” for the setting of the parameters of the sum is displayed; press
ENTER/PRINT to access to the parameters:
- - “SuM.dEC”: number of decimals (between 0 and 3);
- - “SuM.uM”: unit of measure (one can select kg, g, Lb or t).
- - “SuM.diV”: minimum division (the possible values are 1, 2, 5, 10, 20, 50, 100, 200);
- - “SuM.MAX”: maximum value displayed (between 100 and 999999 without decimals); if the sum of the weights has a
value of more of 9 sum divisions (“SuM.diV”) greater than the value set in this step, the message “oVEr” is alternated
to the display of “- - - -“ and an acoustic signal is emitted. The 0 value disables this function.
In the SLAVES, instead, one needs enter a code (between 01 and 32, to identify each single SLAVE) in the step SEtuP >>
SEriAL >> CoM.PC >> PCModE >> 485 (see set-up environment, TECH.MAN.REF.).
11.6.3 FUNCTIONING
When turned on, the MASTER predisposes itself for the connection to the SLAVES present (“ECo n” message appears, in
which n is the SLAVE number which is to be detected): if it has detected more than one SLAVE, it shows the “SuM”
message and then the sum of the weights of all the detected SLAVES; if only one SLAVE is detected, it positions itself on
that scale.
If the MASTER indicator has a 5-key keyboard, by pressing the MODE key:
- if just one slave is configured this is repeated also on the active slave in that moment;
- if various slaves are configured one goes from SLAVE to SLAVE, in order by 485 addresses: the display shows
“SCA n” (in which n is the SLAVE number); after this, the weight transmitted by the selected SLAVE is displayed.
By pressing the ZERO, TARE and ENTER/PRINT keys on the MASTER, these are repeated also on the active SLAVE
in that moment.
It is possible to view the sum of weights present on all the detected scales, (also if lower than the number set in
the F.ModE >> FunCt >> MAStr >> nuMSL step, as long as it is greather than 1), by pressing the MODE key pressed
for a few seconds: the display shows “SuM” and then the sum of the net weight present on the detected scales.
In the display of the sum:
- The reference unit of measure is the one set in the “SuM.uM” step.
- If the sum of the weights is greater than 999999, the segments in the upper part of the display are turned on.
- If the sum of the weights is less than -99999, the segments in the lower part of the display are turned on.
- If the sum of weights is not valid (because one or more slaves is in underload or overload), the segments in the
central part of the display are turned on and an acoustic signal is emitted.
- It is possible to execute the manual or the semiautomatical tare of the sum (in both cases the PT symbol on the LCD
display is activated).
If the MASTER indicator has a 17-key keyboard, the functioning is the same as the preceding one. Furthermore by
pressing the numeric keys:
- if just one slave is configured this is repeated also on the active slave in that moment;
- if are configured from 2 to 9 slaves,it is possible to directly select the desired SLAVE through the relative numeric key
of the keyboard (I.E.: MASTER press the 1 key selection of SLAVE 1).
- if are configured 10 or more slaves, it is possible to select the desired SLAVE by entering the corresponding number
through the numeric keys and then pressing the ENTER/PRINT key (I.E.: MASTER press the 1 key press the 0
key press ENTER/PRINT selection of SLAVE 10).
- if has been set the value “kb.dFkr” (keyboard for DFWKR instruments) in the step FunCt >> MAStr >> nuMSL >>
t.KEyb, by pressing the numeric keys it is possible to:
- - select the corresponding scale, if the sum of weights is displayed;
- - select the corresponding platform, if the weight of a slave is displayed.
