BlueLogic
®
System
The Model DST-4 Regenerative Air Sweeper uses a BlueLogic
®
control system to interface
the auxiliary engine and control sweeper functions. BlueLogic
®
is a multiplexing control
system which has the ability to process logic and communicate with other electronic devices
on the sweeper. The BlueLogic control module is located on the front of dust separator and
communicates with the HMI display, 8 bank switch pack, and the auxiliary engine control
unit or ECU over the primary Control Area Network (CAN) datalink cable. The CAN datalink
is made up of one cable consisting of three wires (green, yellow, and a shield wire). The
control module is constantly monitoring the state of the 8 bank switch pack, the HMI display,
and each discrete module input. The control module processes these state changes and
activates its outputs or sends command messages over the primary CAN datalink to these
devices as programmed.
Some functions on the Model DST-4 are controlled discretely rather than through the
BlueLogic
®
module. The functions controlled by the BlueLogic module are: gutter brooms,
pickup head, main water system power, auxiliary hydraulics motor, and variable speed gutter
broom valve. Some examples of the discrete switches are the work lights, individual water
nozzle circuits, optional hydraulic circuits, etc.
The Model DST-4 with Final Tier 4 emissions is powered by an electronically controlled
auxiliary engine. The engines ECU controls, monitors, and protects the engine from
damaging itself. The ECU broadcasts engine information to the HMI display on the control
panel. In the event of an engine derate or shutdown condition, the display will communicate
the engine fault to the operator. The display also monitors and commands certain functions
of the auxiliary engine over the primary CAN datalink such as the regeneration of the exhaust
system and engine speed.
To protect the integrity of the BlueLogic control system, user installed lighting or electrical
accessories should be avoided. All aftermarket installed circuits should be powered through
the spare circuits on the fuse panel under the control panel or the auxiliary power distribution
panel.

CONTROL MODULE
The BlueLogic control module is powered by the 12V chassis electrical system and grounded
through the module harness. The module is mounted to the front of the dust separator. See
