WST 3 is a high performance transmitter, designed for industrial measuring
by means of strain gauge transducers. It can be used as a slave unit,
communicating with a network master/PLC by Modbus or Profibus.
The network can be used for transmission of commands and measurement
values and also for set-up of the transmitter.
The compact transmitter is easy to install on a DIN rail or a flat surface.
This instruction includes the basic installation and quick set-up, required for
correct measurement with the transmitter.
Additional installation and set-up of more functions, not covered by this
description, can also be performed.
For a complete transmitter description, refer to publication 600 630:

Operating instructions
General
This section describes the display and the function key operation when WST 3
is in normal Operating mode.
Power supply
Power supply to the transmitter should not be turned off during week-ends and overnight. Continuous power supply to electronics and transducers prevents moisture
condensation in the units.
Start-up
As soon as power is connected to the transmitter, start-up is performed.
The text ‘WST 3’, the programme name and the serial number of the transmitter
are displayed for about five seconds.
Then WST 3 is automatically switched over into Operating mode.
(If the transmitter is set for operator start-up, the text
‘Press ENTER to start WST’ is displayed until the function key
to the right is pressed and the transmitter enters Operating mode.)
If an error occurs the start-up halts and an error message is displayed.
Error codes and error corrections are described in the Technical Manual for WST 3,
section 8, Troubleshooting.
As WST 3 enters in Operating mode, the first view is a standard view. It contains
the measurement value, status of the used relays (R1:/R2: '1' = on or '0' = off) and
at the lower right corner an area with information about the Modbus communication.
In this area 'EXT' means serial communication to an external display. An 'address'
means that the transmitter is set for Modbus communication with a master unit, and
the address flashes as a message to the transmitter is received. If the area is empty
this means that the serial communication is not in use.

Profibus status.
This view is always available.
The upper line displays the Profibus address of the transmitter and
the lower line contains status information for the Profibus communication.
Taring
Taring means storing the actual gross weight as a tare value and switching WST 3 over
to display of net weight. The net weight is the difference between the gross weight and
the tare value.
Taring of WST 3 is always possible as the weight value is valid.
Taring is performed as digital input IN1 (terminal 15) is activated with 24 VDC.
The tare value is automatically set to zero by zero setting of the WST 3.
Display of Gross/Net
By weight display, an area to the left of the weight value displays 'Net' when
the net weight is displayed.
If the area is empty, the displayed weight is the gross weight.
Switching between display of net weight and gross weight takes place as
digital input IN2 (terminal 16) is activated with 24 VDC.

Operating instructions, Quick installation
Zero setting
Minor correction of the zero setting can be performed during normal operation from
the ‘Zero setting’ view, see page 4.
But to perform a basic zero setting of the gross weight, the normal operation must be
interrupted and the following sequence carried out with WST 3 in set-up mode.
This type of zero setting is a part of the calibration sequences, but a separate zero
setting may also be needed, for example if the equipment on the scale has been
changed, influencing the weight.

Transmitter WST 3
Installation
Mechanical installation
Each transmitter WST 3 contains several circuit boards, built into a protective plastic
housing which can be snap-mounted on a 35 mm wide DIN rail, or mounted on a flat
surface by two 4 mm screws.
The transmitter should have at least 10 mm free space on each side.
Electrical installation
For the electrical connections to the connector and terminal blocks of the transmitter
shielded cables are needed, except for the power supply. All cables should be routed
so that electromagnetic interference from power cables is avoided.
Cable connection is shown in the diagrams below.
Transducer input
Terminals 1 – 7 (8).
Transducer connection should be handled with great care to achieve best measuring
data. Integrated transducer cables may not be shortened.
NOTE!
Transducer cables must be routed at least 200 mm away from 230/380 V,
50/60 Hz power cables. By cables with other frequencies or high power,
an even wider distance is preferable.
4-wire connection should be used if the integrated transducer cable can be connected
directly at WST 3. By 4-wire connection, excitation and sense must be interconnected
at the transmitter, see diagram below. The cable shield and
terminal 5 should be
connected to earth via the mounting rail.
6-wire connection should be used if the integrated cable must be lengthened or if several
transducers should be connected to the transmitter.
Connect the cable shield and
terminal 5 to earth via the mounting rail. In the diagram
below connections are shown for the junction box SL-4 from Vishay Nobel.

Set-up programme deltaCOM
Transmitter WST 3 should be connected to transducer(s) and power supply. Then it is
possible to perform a set-up from the front panel or from a connected PC with
Windows 95/98/2000/XP/NT4.0. A diskette with the set-up programme deltaCOM is
included in the WST 3 delivery. This diskette also contains instructions for connection
and set-up of the serial communication between the transmitter and the PC.
Through deltaCOM it is possible to find all modules communicating with the PC,
and to study and edit all set-up parameters for these modules.

Transmitter WST 3
Quick set-up, calibration
General
Set-up of all parameters in WST 3 can be performed from the control unit by serial
communication, using the programme deltaCOM. Set-up can also be performed from
the transmitter front panel, for example the ‘Quick set-up’ of certain parameters
described in this section.
Calibration is essential to get correct measurement results.
Two calibration methods are available in the ‘Quick set-up’:
Data sheet calibration, for calibration when transducer data are available and
the installation is free from disturbing mechanical forces.
Dead weight calibration, normally the most accurate calibration method,
where known weights are used to give well defined loads on the scale.
Before selection of calibration method, the value of some common parameters must
be set.
All parameter values from the calibration should be noted in the set-up list, see
Appendix 1. These values are useful later, if the transmitter must be replaced.
Common parameters
These parameters define: the language, measurement unit and resolution used by
the transmitter, and also the capacity and signal type for the analogue output.

This calibration type can be used when transducer data is available, the load is

by disturbing external forces.
Before editing of the following parameters is started, set-up of common parameters,
described in points 1. – 8. on pages 9 – 12 should be performed.
9. Edit the conversion factor.
If the ‘Data sheet’ alternative was chosen at 8. on page 12, next parameter will

expressed in the measurement unit, should be multiplied to be expressed in
the data sheet unit.
Default value for the parameter, 9.80665, can be used when the data sheet unit
is Newton (N) and the measurement unit is ‘kg’.
