Honeywell DR4300 Product Manual page 15

The six keys are used to select the real time value to be displayed, and to select set up parameters and their
values during configuration. The display and keypad are behind the door, protecting them from dirt.
A supplementary external keypad is also available.
For more information about the operator interface on models having a display and keypad, see Subsection
4.2.
Configuration
The models without a display are configured with two switchbanks: one for configuration, the other for
input definition. Configuration is a simple matter of consulting a table in this manual; selecting the
appropriate combination of range, chart speed, engineering unit, and input type; then setting the switches as
shown in the table.
The display and keypad are used to configure models with these options. When the unit is in configuration
mode, set up parameters are displayed, and grouped by function. Designate site-specific values by selecting
them from a list of choices, or entering them as numeric values. The operator can be locked out from
making configuration changes.
The models with display also use a switchbank to define the type of input to be expected by the hardware.
Input parameters used by the software are configured using the display and keypad.
Self-diagnostics
All DR4300 recorders run self-diagnostics at power up and in the background during normal operation.
Problems are reported by error messages on the display when present. An LED in the models without a
display lights if the unit fails a self-diagnostic.
Construction
All DR4300 recorders are housed in a rugged molded case which can be panel-, pipe- or surface-mounted.
An acrylic-windowed, gasketed door protects internal components from harsh environments while allowing
easy access to the chart.
