Safety instructions
S For devices operating in networks, safety precautions must be taken in
terms of both hardware and software, so that an open circuit or other inter
ruptions to signal transmission do not result in undefined states or loss of
data in the automation device.
S Following work on settings or password-protected activities, make sure that
any controls that may be connected remain in a safe condition until the
switching behavior of the device has been tested.
Additional safety precautions
Additional safety precautions to meet the requirements of the relevant national
and local accident prevention regulations must be taken in plants where
malfunctions could cause major damage, loss of data or even personal injury.
The scope of supply and performance of the device covers only a small area of
measurement technology. Before starting up the device in a system, a project
planning and risk analysis must first be implemented, taking into account all the
safety aspects of measurement and automation technology so that residual
risks are minimized. This particularly concerns personal and machine protec
tion. In the event of a fault, the relevant precautions must establish safe
operating conditions.
If this device is used as a component in a system, the system design must be
checked by qualified specialists who are familiar with the design and function of
all the individual components!
General dangers of failing to follow the safety instructions
The device is state of the art and as such is failsafe. The device may give rise
to residual dangers if it is inappropriately installed or operated.
Exercise caution when pressing the keys that control movable system parts
such as conveyor systems, flaps, etc. Before pressing these buttons, make
sure that no persons are in the danger zone of moving system parts!
The weighing terminal must not be used in a potentially explosive atmosphere.
It is the responsibility of the owner of the equipment to classify potentially ex
plosive areas (division into zones, equipment groups, temperature classes,
12 A4774-1.0 HBM: public WTX110
Page 15
Safety instructions
etc.). Local labor inspection authorities and technical inspection agencies can
be of assistance here!
The power input terminals of the device must be connected to safety extra low
voltage (12…30 V
). When connecting external components with their own
DC
power supply (e.g. serial interfaces), care must be taken to ensure that only
SELV is used in that case as well! This applies to variants with 12…30 VDC
power supply.
The weighing terminal contains a lithium battery for storing the data that is
entered. There is a risk of explosion if the battery is replaced incorrectly. It
must only be replaced with the same type of battery, or an equivalent type
recommended by the manufacturer. Dispose of used batteries in accordance
with the manufacturer's instructions.
Notices:
S All switching devices (e.g. relays and contactors) that are connected or in
the immediate vicinity must be wired to effective noise filters (RC filters,
free-wheeling diodes).
S In order to avoid static charge buildup, all metallic parts of a system must
be thoroughly grounded. Moving parts, such as portable scales on plastic
wheels, must be grounded with ground clamps or ground leads of
appropriate diameter.

Power supply
The power supply is connected to terminal 4.
WTX110 A4774-1.0 HBM: public 25
Page 28
Installation
The device power supply must not simultaneously supply machines or
equipment that cause grid interference (motors, relays, heaters, etc.). Even
brief surges or drops in the voltage supply can adversely affect how the device
functions or lead to damage. An uninterruptible power supply (UPS) or voltage
stabilizer can prevent this.
The device must be incorporated into the potential equalization of the system.
There is a threaded bolt on back for this purpose.
4.4 General cable assembly
All connection cables are directed through the bolted cable connection on the
bottom of the device to the inside of the housing.

Check
nut
► Slide the swivel nut over the cable sheath.
► Push the plastic insert over the cable sheath until the right edge of the
insert meets the end of the cable sheath.
► Unbraid the shield and lay it as flat as possible over the right part of the
plastic insert so that the shield is conductively connected with the housing.
The shield wires must not be longer than the right part of the insert.
Otherwise the bolted cable connection no longer provides a reliable seal.

Installation
► Guide the cable with plastic insert into the metal housing.
► Screw on the swivel nut and tighten it with a screwdriver.
WARNING
Cut the individual wires to length so that the parts conducting mains voltage
(connection cable, power supply unit) cannot touch! Use wire end ferrules for
leads with fine wires and make certain no individual wires are sticking out.

4.5.1 Connection cable for analog load cell
When laying scale connecting cables (analog load receptors) please note:
S Use only suitable scale connecting cables:
WTX110 A4774-1.0 HBM: public 29
Page 32
Installation
- Keep to the rated voltages of the connecting cable.
- Double-shielded cable is advantageous (braided shield)
- The length and cross-section of the individual wires must meet the
following conditions:
Cable length (m) / cross-section (mm@) v270 (m/mm@)
- Maximum line length between load cells and weighing terminal: 200 m
S The shield of the load cell cable must be fitted across a large area all-round
in the screwed cable gland of the weighing terminal. This can be done with
all WTX110 variants. An additional connection for potential equalization is
located on the bottom of the WTX110.
S The load cells and load receptors, terminal boxes and weighing terminal
must be integrated into the equipotential bonding system. To do this,
depending on the local conditions, it may be necessary to lay a separate
equipotential bonding line with a corresponding cross-section (e.g. 16mm@).
S Use only metal terminal boxes to extend cables, and fit the shielding for
both cables in the screwed cable glands.
S Cable laid a minimum of 50 cm away from power lines. Lay cable in
grounded steel conduit, metal tubing or metal cable ducts.
S When load cells are under tension rather than compressive load, the +
and – signal connections must be swapped.
4.5.2 Saving calibration data for legal for trade applications
The calibration data can be saved on the ADM motherboard with jumper W1.
In the factory settings W1 is always set to calibration enabled!
30 A4774-1.0 HBM: public WTX110

Installation
Calibration data saved:
Jumper set
Enable calibrating and saving: Jumper in
this position or completely removed
Information
Not removing the W1 jumper completely, or only removing it for replugging and
proceeding with care when moving the jumper is recommended to prevent the
jumper from being lost!
When setting the jumper, take care to ensure it is set on both pins to ensure
reliable calibration.
WTX110 A4774-1.0 HBM: public 31
Page 34
Installation
The position of the W1 jumper can be locked by a
weights and measures officer with thread and lead or a
seal:
A description of calibration can be found in section 11
"Calibration," page 159!
4.6 Serial interface connection
The WTX110 generally ships with the variant configuration with pre-wired
options.
RS232 or RS485 (4-wire) can be selected as serial options. The serial interface
module is always plugged into slot SIM1.
Fig. 4.3 Positioning the serial module on the WTX110 motherboard (CPU1)
32 A4774-1.0 HBM: public WTX110

Installation
Transfer lines connecting the serial ports must be installed so that inductive
and capacitive interference from other lines, machines or electrical devices is
ruled out. Interference on data transfer could result in delays or in the program
stopping.
To ensure optimal interference suppression of all injected frequencies, the
shield should be applied on both sides.
In the event of fluctuations in ground potential, a compensating current may
flow via the double-side shield. In this case an additional equipotential bonding
line must be laid.
WTX110 A4774-1.0 HBM: public 33

Installation
Important
Terminal designation: Some manufacturers of components with RS485 ports
designate the terminals differently. According to the standard, the TxD+ / RxD+
port is designated 'B' and the TxD– / RxD– port 'A'.
Important
Cable: Always use twisted-pair cables! The surge impedance of the cable
should be approximately 150 W.
When laying cables for serial interfaces please note:
S Transfer lines connecting the serial ports must be installed so that inductive
and capacitive interference from other lines, machines or electrical devices
is ruled out. Interference on data transfer could result in delays or in the
program stopping.
S Self-wired cables must meet the following specification:
Shielded with twisted pairs, for example LIYCY 3 x 2 x 0.14 mm@ or LIYCY 3 x 2 x
0.25 mm@; shielded applied on both side
Cable resistance ≤ 125 Ω/km

Y Start sending ICMP packets to the
gateway
Note: In some networks it might be necessary for
the weighing terminal to send data packets at
regular intervals, because the intermediate point
(gateway, router or switch) cuts the connection if
there is no communication for a lengthy period of
time. If Auto PINGis activated, an ICMP packet is
sent every 60 seconds.

S The reference weight can be determined by entering a value or by weighing.
When the reference weight is determined by weighing, the program
automatically performs unit weight optimization. This ensures that the
counting process will run with the maximum possible accuracy.
S If too many items are placed on the scale during the optimization, an error
message appears.
S The suggested number of reference parts is 10, but it can be changed.
S Counting into an empty container or counting from a full container are both
possible.
S The setting of the outputs can be adjusted in Service
mode\Application\General Setup\Output 1 or ...\Output 2
S Switching points S1 and S2 can be set in Supervisor Mode to allow for a
tolerance check (see section 10.1 "Supervisormode/General", page 130).
S If an optical tilt sensor is connected, Input 2 is no longer available for
functions of the operating modes.
