3.3.7 SETTING THE COMMUNICATION WITH DIGITAL CELLS
Premise
: Only load cells of the same model and the same capacity can compose two digital platforms.
In the case in which one chooses a digital cell type in the
CELtyP
step, the following operations are required:
1)
Check the correct matching of the ComAuX to the COM3 in the step
SEtuP >> SEriAL >>
PortS
;
2)
Set the number of scales; enter in the
nuM.SCA
step and select with the
arrow keys:
-
Remote
: only for remote scale (calibrations are not carried out)
-
1 SCALE (485 connection)
-
2 SCALES
and select the type of cells used and the number of digital cells / analogue channels connected for each scale.
The selection of a digital load cell type sets the correct communication parameters with the cells (see
SEtuP >>
SEriAL >> CoM.AuX
step. Moreover
ProtoC
must be set as
nonE
).
3)
In case of DGX conversion card selected as load cell type, it will be required to select the functioning MODE.
4)
Select “Multicells mode” in order to enable the conversion into digital of each single analogue load cell connected to
all the DGX cards.
5)
It will be possible to enter the number of DGX cards that are used to convert the total load cells forming ALL THE
SCALES.
EXAMPLE
: with DGX8 conversion boxes one has to consider 2 cards for each used conversion box (for
example with 2 DGX8, set 4 DGX cards).
6)
The display shows
SET.485
: press enter to access setting the 485 address of each load cell / DGX.
7)
The first address is proposed, confirm with ENTER and enter the first cell / DGX card serial number.
The last entered serial number is proposed for that address.
In the case of DGX conversion card selected as load cell type, after the serial number confirmation it will be
possible to enter the number of load cells connected to that conversion card.
Press
ENTER
to choose the next address and repeat the operations, or
C
to exit the step.
8)
Once all the connected cells have been assigned the message “-END-” will appear; by pressing the
C
key it will be
required to send the configuration; confirm with enter or
C
to cancel.
The indicator informs with an acoustic signal and the text "Error" if:
a.
The remote scale is enabled in the CoM.AuX (see the
SEtuP >> SEriAL >> rEM.SCA
step);
b.
The
SEtuP >> SEriAL >> rEAdEr
step is set as
CoM.AuX
;
c.
One tries to enter an address with a value greater than the cell number set in the
CELtyP
step;
d.
The serial number is wrong or not corresponding to the ones of the connected cells;
e.
The entered serial number is the same of the one of a cell already connected to the indicator with another 485
code. Correct the serial numbers till all of them are confirmed with "- oK -".
f.
The serial number is correct but:
The type of cell set is wrong (see the
CELtyP
step);
The assignment of the indicator ports is wrong (see the
SEtuP >> SEriAL >>
PortS
step);
The cell communication parameters are wrong (moreover
ProtoC
must be set as
none
, see
SEtuP >>
SEriAL >> CoM.AuX
);
There are some problems with the physical connection of the cells (expecially check the terminal
connections and the cell power supply);
g.
The number of total load cell or the number of the load cell connected to a DGX is wrong.
In case of error, the display shows the "rEtry?" message and it’s possible to press
ENTER
in order to repeat the
operation; otherwise, press
C
to exit the step.
