Introduction and overview
A new programming pendant , type WSP3 is available, and provides a
larger multi-line display, making programming easy.
A powerful built-in logic sequencer program provides the timer with a
flexible means of fully controlling small machines or tooling
arrangements, without the need for additional hardware.
A plug-in option board provides a 10/100Base-T Ethernet connection.
Units may then be networked to a PC running WS98-2003 software
for programming and monitoring purposes.
Fieldbus operation (Profibus, Interbus, DeviceNet Modbus etc.) is
supported via plug-in option boards.
The new WELDSTAR model WS2003 is a direct plug-in replacement for the original WS2000. It
will fit into existing cabinets, and will work with the existing power supply. Existing connections
are duplicated, including outputs at 110V AC or 24VDC. MF operation is also supported.
This manual details the features of the WS2003 timer, and shows how
to program the timer using the WSP3 programmer.

…functions
In early 2008, a number of new circuits were added to the original design.
These are used to provide the following additional features:
• 0..10v or 4..20mA input for pressure monitoring.
• Two general purpose 0..10V inputs can be used by the sequencer. One of
these inputs may be used to connect a CT for current measurement.
Note that these features are not available when running this firmware on the
original design.
