2.4 Hardware Configuration and Wiring
The CPU board in the DLR series has been designed for easy access to wiring and configuration of all available
inputs and outputs. In addition to easy access, the wire and configuration mapping provide clear labeling of all
input and output signals and the associated configurations of their device drivers.
Figure 2-2. CPU Configuration
NOTE: Unit is shipped previously set up and configured. For information on changing hardware configuration see
Section 5.11 on page 21.
2.5 Display/Keyboard Functions
See Figure 2-3 on page 5 for information on display and keyboard functions.
• Six-digit LED display of the measured pressure (1).
• Three annuciators: Two of the LEDs are used for indicating whether the unit is operating as a GAGE
pressure unit or as an absolute (ABS) pressure unit. The LED marked
P indicates that the unit is in the
delta P display mode (2).
• Eight character LED display for indicating the conversion units that the pressure data is currently being
displayed in. This display also scrolls prompting messages if corrective action is required or a problem
occurred in performing an operation (3).
For example, if attempting to perform a push to ZERO while the pressure data is in motion, the display
shows
Unit is in MOTION .
• In GAGE units, the ZERO function key (4) allows the indicator to be zeroed if it is within the limits
defined by the ZERO configuration.
• DISPLAY key (5). In the normal operating mode this key is used to select and view all active displays that
were enabled in the Configuration mode (i.e., Pressure data, MIN/MAX data, Freeze mode data, and
delta P display mode data).
