Environmental Considerations
The following environmental considerations must be taken into
account when installing the TMC470 Controller.
Contaminants.
The vented TMC470 is rated NEMA 1 (IP30) and
contains a thermostatically-controlled, variable speed fan.
Accordingly, in environments where solid and/or liquid
contaminants are present, the possibility exists that these
contaminants can be drawn into the TMC470 controller and
possibly result in failure. For that reason, in these types of
environments, the controller must be located in a sealed industrial
enclosure. To facilitate such installations, Telesis offers on
optional panel mounting kit for use with an appropriate customer-
supplied panel or enclosure. Telesis also offers an optional
TMC470N NEMA 12 (I.P. 65) enclosure in which the controller
can be mounted.
EMI Susceptibility.
Although the system has been found to be in
compliance with pertinent susceptibility standards, care should be
taken when installing near welders and other extreme generators
of electromagnetic interference (EMI). Particular care should be
taken to ensure welder currents are not injected through the
marking head chassis. The marking head chassis is connected to
the electrical service earth ground through the marking head cable.
The marking head should be electrically isolated from all surfaces
which could become part of a welder current path.
TMC470-based System Software
The system software is permanently installed in the controller. It
provides the user interface for the operator to control the marker.
The software also provides a library for storing, loading, and
editing user-defined patterns. Patterns are files stored in the
controller’s memory. Depending on the size of the pattern files, the
controller can store up to 200 patterns. Each pattern contains one or
more fields; each field defines a single object. Printable objects
may be created to define text strings, arc-text strings, geometric
shapes , graphics, and machine-readable data matrix symbols. Non-
printable objects may be defined to specific commands to the
marker (e.g., Pause, Go to, Input, or Output). Printable text fields
may include alphanumeric characters, symbols, and special
message flags. Message flags automatically insert data into the text
string, such as serial numbers, times, dates and user-defined codes.
PC-based Merlin III Visual Design Software
Optionally, the TMC470 Controller may be connected to a PC that
runs the Telesis Merlin III Visual Design Software. The software is
a 32-bit Windows
®
based
WYSIWYG
application that provides a
graphical user interface to make pattern design quick and easy. Just
“click and drag” for immediate adjustment to field size, location, or
orientation. The Merlin III software includes tools to create and
edit text, arc text, rectangles, circles, ellipses, and lines. Existing
DXF files can also be imported for marking.
After downloading patterns to the controller, the PC can be
disconnected from the controller to allow the TMC470 to control
marking operations. Optionally, the PC may remain connected to
the controller and allow the Merlin III software to fully control the
marking system.
