AW16000 - Instruction Manual
CAUTIOn :
Do not use telephone jumper cables. Thesehave a “twist” in the connection and may
damage the controllers. Cables designed for use with the DCT1000are available from Dwyer
Instruments (Model DCAC02-2 ft., DCAC04-4 ft., etc.).
CAUTIOn :
Prior to installing the DCP100a/200a please review the operating specifications
carefully. Some operating systems, especially in pneumatic conveyingapplications, may see
static pressure or vacuum conditions that exceed the capability of the DCP100a/200a pressure
module. For these conditions there are a number of alternate Dwyer pressure products that
can be used to meet your application requirements, all of which can be terminated to the
Dwyer DCT1000 Dust Collector Timer Controller. For more information on these and other Dwyer products,
please call us at (219) 879-8000, or visit us on the web at www.dwyer-inst.com or www.dust-controls.com.
1.2.5 Continuous Cycle Mode
The master controller has several operating modes available for different applications. Starting with the
most basic mode, it is capable of operating in a continuous cleaning cycle. This can be initiated by either
placing a jumper between the high limit input and the common, or the manual override input to the
common connection. Controlling this cycle are three setup parameters: time off, time on, and cycle delay.
Time on and time off specifically deal with the solenoid on time and the time interval between the end
of the on pulse and the start of the next. The cycle delay allows a delay of up to 255 minutes to be
programmed between the end of one complete cleaning cycle and the beginning of the next. This allows
additional options for defining a cleaning profile.
1.3 DCP Installation
1.3.1 Location
The system should be located in an enclosure that meets relevant safety standards and electrical codes.
There are no other special orientation requirements as the pressure module is not orientation sensitive.
Care should be observed when routing the air hoses to ensure that any potential condensation or moisture
will not drain into the sensor. Where heavy condensation is present, a drip loop or an in-line filter should
be installed to ensure long term operation.
