NOTE
Neither the design of the device nor any technical safety aspects may be mo-
dified without the express permission of Hottinger Baldwin Messtechnik
GmbH. Any modification excludes Hottinger Baldwin Messtechnik GmbH from
any and all liability for any damage resulting therefrom.
When replacing the battery for the real-time clock, the device must be discon-
nected from the power supply (service life 5 years).
It is strictly forbidden to carry out any repairs and soldering work on the mo-
therboards or to replace any components. Repairs may only be carried out by
persons authorized by Hottinger Baldwin Messtechnik GmbH.
The production number set at the factory cannot be changed.
When connecting the cables, the device must be disconnected from the vol-
tage supply.

Safety instructions
•There are not normally any hazards associated with the product, provided
the notes and instructions for project planning, installation, appropriate ope-
ration and maintenance are observed.
•Each time, before starting up the modules, you must first run a project planning
and risk analysis that takes into account all the safety aspects of automation
technology. This particularly concerns personal and machine protection.
•It is essential to comply with the safety and accident prevention regulations
specific to the particular application.
•Installation and start-up must only be carried out by suitably qualified personnel.
•Do not allow damp and dirt to get inside the device when connec. the cables.
•When connecting the cables, take action to prevent electrostatic discharge
as this may damage the electronics.
•The required power supply for the device is an extra-low voltage (10...30 V)
with safe disconnection from the mains.
•When connecting additional devices, comply with the safety requirements.
•The ground connections of the supply voltage, the interface and the load
cell cable shield are interconnected in the device. If the potentials of the de-
vices to be connected are different, suitable steps must be taken to isolate
the signals (such as using an optocoupler).
•Shielded cables must be used for all connections apart from the supply vol-
tage (see note below). The shield must be connected to the provided termi-
nals (Chapter 5.3, page 12).
•The use of unshielded cables for the voltage supply is only permissible for
cables with a maximum length of 30 m, laid inside buildings. If cables are
longer or are installed outside buildings, shielded cables must be used (as
per EN 61326−1).
•To compensate for potential differences, the metal housing of the
DWS2103 must be connected to the scale structures as well as to the
ground potential of the connected devices by a low-resistance equalizing
conductor. This is unnecessary if a potential difference of 35 V is not ex-
ceeded.
•In the device, the reference ground (GND) of all the signals and the supply vol-
tage is connected directly to the cable shield connection but not to the housing.
•Connection to a wide-ranging supply network is not permitted as this often
causes interfering voltage peaks to be coupled into the electronics. Instead,
a local supply must be provided for the DWS2103 (even when grouped).
•The front foil is made from high-quality materials, providing a service life
appropriate to the external conditions. The keys must only be operated by
hand; under no circumstances must pointed objects be used to press them.

4 Scale commissioning overview
The permissible supply voltage for the DWS2103 is in the range of
+10...30 VDC and must be adequately smoothed (rms value less residual rip-
ple >10 V).
NOTE
When the C16i digital load cell is supplied via the DWS2103, the permis-
sible supply voltage is +10 ... 17 VDC
Type FIT, PW...i and AED... digital load cells can be operated with +10 to 30 VDC.
A 100...240 V power supply unit is available as an accessory (AC/DC15 V / 530
mA, for max. 8 load cells). This power pack is suitable for all digital load cells.

5 Electrical connections
5.1 Notes
Please observe the safety information at the start of this description.
The load cells and the supply cables are connected by means of screw termi-
nals on the back of the device. The terminals are fitted with wire protection
and the use of end sleeves is recommended, particularly for the load cell ca-
bles. The assignment of the connection terminals is displayed on the back of
the device.
NOTE
All the ground connections are interconnected on the motherboard!
5.2 Cable connection
All connections are accessible from the outside, the housing does not need to
be opened. Strain relief for the connection cable can be implemented via the
supplied terminal housing. It permits the use of round cables with a diameter
of 5...7 mm.
To minimize EMC problems, the individual wires from the end of the shielding
to the terminal should be as short as possible.
The cable shieldings must be twisted together and connected to one of the
terminals 1.1, 1.8, 2.1 or 2.8.

DWS2103

HBM A2936-1.0 en/de
5.3 Cable preparation
•Remove the outer sheath about 20 mm.
•Twist braided shield.
•If necessary, remove the inner sheath.
•Strip the wire ends about 5 mm.
•Connect the wires to the terminals.

5.4 Load cell connection
Only digital load cells or weighing electronics (FIT, AED, PWxi) can be con-
nected to DWS2103. An RS485 interface and a CAN interface are available
on DWS2103 for this purpose.
Load cells and weighing electronics can be operated via the main channel on
DWS2103 as well as via the diagnostic channel. Care must be taken to en-
sure that all weighing units connected to the BUS are connected either via the
main channel or via the diagnostic channel.
There is a choice of interface to use with the weighing units:
Main channel: RS485 4-wire (full duplex), RS485 2−wire (half duplex)
or CAN
Diagnostic channel: RS485 2-wire (half duplex) fixed baud rate 38400 Bd,
even parity
Mixed operation of the main and diagnostic channels is not permissible, nor is
using different interfaces (RS485, CAN).
Factory settings for all digital weighing units (such as FIT, AED, etc.), are ad-
dress 31 (for RS485) and address 63 (for CAN).
If several load cells with factory settings are connected to a scale, the load
cell addresses must first be changed. These settings are made in the ”BUS
SCAN” parameter menu.
NOTE
Call up the parameter menu ”BUS SAN” after connecting the load cells.
