AQC Dust Collecting Systems
Electrical connection for DCT-500
sequencer
The
Maxiflo-VC unit is equipped with 115
VAC solenoids which activate the cleaning
valves. Those solenoids are integrated in a
NEMA 4/12 box behind the filter cabinet and
above the air tanks. Connections for those
solenoids are factory wired. The DCT-500
sequencer activates the solenoids in a cascading
sequence operating the cleaning valves.
Drawing # 5 shows a typical connection for a
DCT-500 sequencer with starter. The electronic
board is activated upon fan start up using an
auxiliary contact. The electronic board is fitted
in a NEMA 4/12 box.
To activate the pulse cleaning system when the
fan is OFF, install a selector or timer with
constant feed on the inlet connector of the
electronic board.
Refer to page 2 of this document to program the
sequencer.
