10.3 Electrical connection for DCT-1000 sequencer
The MAXITOP dust collector is equipped with 115V solenoids which activate the cleaning valves.
These solenoids are grouped in a NEMA 4 ½ panel installed behind the cabinet, above the air tanks.
A differential control panel (DCP) may also be included on the electronic panel. Wiring for these
solenoids is factory assembled. The DCT-1000 activates the solenoids in sequence in response to
either cartridge pressure drop or a continuous bases. Figure 2 represents a typical connection with
a starter to a DCT-1000 sequencer card. The electronic panel is activated in parallel with the fan
startup. This operation will regulate the pulsation required as per the status of the filters.
