General Description
This series of displays accepts industrial sensors to allow various physical measurements to
be made, such a weight, temperature, pressure, humidity etc. Different models are available
for different sensor types.
The main function of this series is to give a clear numeric readout of the variable being
monitored. Most models include an excitation power output, to power the sensor directly.
Various digit heights are available, to suit the maximum viewing distance required in each
installation. For every 10 metres (33 feet) of viewing distance, use 1” of digit height.
Various optional output modules are also available to give alarm relay outputs, analogue
output or digital communications, or any combination of these options.
Displays are programmed using front panel pushbuttons. The front panel buttons can be
disabled. In addition, you can connect 4 remote wired pushbuttons to the display, so that you
can make adjustments while the display is mounted in an inaccessible location.
Displays have three power supply options : 100-240 VAC, 11-30VDC or 48V AC.
These displays must be installed fully assembled, and must be installed according to local
electrical installation rules.
When properly installed, and provided they have been ordered with cable glands exiting the
lower surface of the case, they provide ingress protection to IP65 / NEMA4X from all directions.
Safety
Obey all safety warnings in this manual, and install the display according to local wiring and
installation regulations. Failure to follow these guidelines may cause damage to the display,
connected equipment, or may be harmful to personnel.
Any moving mechanical device controlled by this equipment must have suitable access guards
to prevent injury to personnel if the display should fail.

There is a wide range of possible locations for the input board, output board and power
supply board/s. Their locations depend on the height of digits, number of digits, brightness of
digits and any installed options. Because the permutation of possible locations is large, we
will not describe the location of boards within the display, but simply identify the connectors
and their functions on each board, below ...
