Note: All compressed air components must be sized to meet
maximum system requirements per the chart below at 80 PSI. See
specification drawing shipped with the unit.
• The compressed air supply must be oil and moisture free.
Contamination in compressed air used to clean filters will result in
poor cleaning, reduced filter life, cleaning valve failure, and poor
collector performance.
• Purge compressed air lines to remove debris before connecting to
the units compressed air manifold.
• Turn off compressed air supply and bleed lines before performing
service or maintenance work.
5.3 ELECTRICAL
5.3.1 Power Requirements
The controller has a “universal” power supply that will allow operation
on 120 VAC to 240 VAC power lines. The input voltage must be between
85 VAC and 270VAC either 50 or 60 Hz. No circuit changes are required
when switching between these voltages. The solenoid loads, however,
must be sized to accommodate the line voltage selected.
5.3.2 DCT1000 Terminal Connections
The line and solenoid connections are located at the lower edge of
the board below the plastic guard. The terminal block is a “Euro”
style connector system that clamps the wire within the connector
body. The connector will accept wire sizes from 14 to 22 AWG. The
wire should be stripped to no more than 0.25 inches to avoid shorts
or expose line voltages creating a potential safety hazard.
To assist you in determining the proper wire gauge required, a strip
gauge is provided at the lower right corner of the board. The
connector system used on the DCT1000 is specified for single
connection but you can piggyback to a single lug provided that local
codes allow for this and good workmanship practices are followed.
NOTICE
Do not increase supply pressure above
100 PSI. Component damage can result.
NOTICE
Do not run control wires, communication cables, or
other class 2 wiring in the same conduit as power leads.
The system may malfunction if class 2 wiring
is run together with power conductors.
