10 ELECTRICAL CONNECTION
WARNING!
The electrical connections must be executed by a qualified
electrician and with respect to codes and regulations. For
safety measures, shut off power supply to the collector prior
to perform the installation. Lock off any power supply prior
to servicing or maintenance.
The dust collector control panel regulates the cartridge cleaning system.
The dust collector control panel may be installed on the MAXIFLO unit, inside or outside the
building or remote of the unit.
1.
Using the electrical diagram supplied with the panel, connect the power supply from the
main breaker (supplied by the customer) to the control panel.
2.
Refer to the descriptive identification plate to select proper voltage and amperage.
3.
If the unit is supplied with a customized control panel, refer to the descriptive schematics to
perform connection to the power supply.
4.
Verify for proper motor rotation.
10.1 Electrical connection for DCT-500 sequencer
The MAXIFLO 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.
Figure 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 22 of this document to program
the sequencer.
