Dwyer Instruments DCT1010DC User Manual

Thank you for purchasing the Dwyer
®
DCT1000DC Dust Collector Timer
Controller. You have selected a state of the art dust collector timer control
that will provide years of dependable operation and service.
The Dwyer
®
DCT1000DC Dust Collector Timer Controller was designed to
be used with pulse-jet type dust collectors for on-demand or continuous
cleaning applications.
Continuous cleaning applications do not require external inputs and can
be used for time based “on-demand” cleaning through use of the cycle
delay feature.
For on-demand applications, the plug-in pressure modules
(DCP100A/200A) can be used to take full advantage of all the features the
DCT1000DC offers, or an external pressure switch can be used for
High/Low limit control.
The Dwyer
®
DCT1000DC was designed so that it is easy to use, thus
allowing for a quick and easy start up for your dust control applications.
The contents inside this installation and operating manual will guide you
through the features of the DCT1000DC and how they can be applied to
get the most out of your dust control requirements.
