EAGLE QUANTUM PREMIER DEVICES
From a configuration standpoint, all DCU’s have the same basic adjustable parameters; Alarm 1, Alarm 2, and
Calibration gas concentration (Cal Level).
The DCU Universal also has a fields for entering the engineering units and unit range for the attached sensor.
The “PV Deadband” field determines what percentage change in the Process Variable (PV) will prompt the DCU
to send an immediate update to the controller instead of waiting for its regularly scheduled message time. The
default is 5%.
The “Gas Mode” selection has two choices; “Gas Detector” or “Other”. The default is “Gas Detector” which limits
the adjustable range of the low and high alarm setpoints to be consistent with regulatory requirements.
Common Settings
The bottom of the “DCU Editor...” dialog box contains buttons for setting all of the common settings on the
device.
