National Controls Corporation-Dust Collector Controls (Model:DNC-T2110 Series)

Operating Logic: The DNC-T2110-A10/B10 are ten output sequencer, cycle timers with adjustable ON-TIME, OFF-TIME and DELAY times. When voltage is applied to L1 and L2 and the pressure switch is closed, the OFF-TIME is started, At the end of the preset OFF-TIME the control will cycle through the outputs until the pressure switch opens. The ENABLE/DISABLE switch on the control can enable the OFF-DELAY. When the pressure switch opens and the OFF-DELAY is enabled, then the the OFF-DELAY time is started and the OFF-TIME, ON-TIME cycles  will continue until the end of the OFF DELAY time. If the OFF-DELAY times out during the ON-TIME, the control will allow the ON-TIME to time out. Upon closing of the pressure switch the control will commence the OFF-TIME, ON-TIME sequence on the next output and the OFF-DELAY time will reset. If the pressure switch is closed during the OFF-DELAY time, the control will reset the OFF-DELAY.  The ENABLE/DISABLE switch on the control can disable the OFF-DELAY. When the OFF-DELAY is disabled and the pressure switch opens, during the ON-TIME, the control will allow the ON-TIME to time out.  Upon closing of the pressure switch the control will commence the OFF-TIME, ONTIME sequence on the next output.
