Models DNC-T2003 thru DNC-T2032 Operating Logic: Input power is applied to the control at all times.  For “On Demand”  cleaning,  closure  of  isolated  control  contacts (pressure  switch)  initiates  the  “Off”  time.    At  the  end  of the  off  time  the  control  energizes  solenoid  no.    1  to provide  a  cleaning  pulse;  it  then  transfers  to  the  next compartment  initiating  the  off  time  again.    This  cycle continues  until  the  control  contacts  open.    The  control remembers the last output activated and will activate the next one in line when the control contacts reclose.  For “continuous”   cleaning   the   pressure   switch   terminals should  be  shorted  together.    A  program  wire  allows  for field selection of number of outputs required. Specifications: Time Delay: On Time:   Adjustable from 50 to 500 milliseconds Off Time:   Range A-adjustable from 1.5 to 30 seconds Range B-adjustable from 8.5 to 180 seconds Repeatability: ± 3% over temperature and voltage ranges Input: Operating Voltage: 105 to 135 volts A.C.  50/60 Hz Output: Type:   Solid-state  switch  rated  at  200  VA  max.    per output. Number   of   outputs   to   be   activated   is   determined   by position of program wire. Protection: Transient Voltage: 30 joule varistor Short Circuit Protection: 3 amp.  fuse Environmental: Operating Temperature: -40 to 150F (-40C to 66C) Size And Hook-up Diagram of Dust Collector Controls, (Exact location of components varies from model to model) Off Model Time Max.
